Executive Summary 

Ocklawaha Basin 

The Water Quality Assessment Report for the Ocklawaha Basin is 

part of the implementation of the Florida Department of Environmental 

Protection’s (Department) watershed management approach for restoring 

and protecting water resource problems and addressing Total Maximum 

Daily Load (TMDL) Program requirements. A TMDL represents the 

maximum amount of a given pollutant that a waterbody can assimilate and 

still meet the waterbody’s designated uses. A waterbody that does not meet 

one or more of its designated beneficial uses is defined as impaired. The 

watershed approach, which is implemented using a cyclical management 

process, provides a framework for implementing the requirements of the 

federal Clean Water Act and the 1999 Florida Watershed Restoration Act 

(Chapter 99-223, Laws of Florida). 

A Status Report, published during Phase 1 of the watershed 

management cycle, provided a Planning List, or preliminary identification, 

of potentially impaired waterbodies in the Ocklawaha Basin. This 

Assessment Report presents the results of additional data gathered during 

Phase 2 of the cycle. The report contains a Verifi ed List of impaired waters 

(Table 4.3 in Chapter 4) that has been adopted by Secretarial Order and 

is pending approval by the U.S. Environmental Protection Agency (EPA). 

TMDLs must be developed and implemented for these waters, unless the 

impairment is documented to be a naturally occurring condition that 

cannot be abated by a TMDL or where a management plan is already in 

place that addresses the impairment and is expected to correct the problem. 

The Verified List also constitutes the Group 1 basin-specific 303(d) list of 

impaired waters, so called because it is required under Section 303(d) of the 

Clean Water Act. See Noteworthy in Chapter 1 for a description of the 

contents of this report, by chapter. 

In the Ocklawaha Basin, state, federal, regional, and local agencies 

and organizations are making progress toward identifying problems and 

improving water quality. Throughout its watershed management activities, 

the Department works with these entities to support programs that are 

improving water quality and restoring and protecting ecological resources. 

The Department’s TMDL Program objectives will be carried out in the 

Ocklawaha Basin through close coordination with key stakeholders and 

initiatives such as the following: St. Johns River Water Management 

District’s (SJRWMD) Surface Water Improvement and Management 

(SWIM) Program, the development of agricultural best management 

practices (BMPs) by the Florida Department of Agriculture and Consumer 

Services, the East Central Florida Regional Planning Council’s Lake 

Apopka Planning Initiative, the Harris Chain of Lakes Restoration 

Council’s lake restoration effort, data collection efforts by the Lake Griffi n 

Stormwater Management Technical Working Group, water and habitat 

quality monitoring in lakes and urban streams as part of the Orange Creek


Basin Partnership, the work of the Silver Springs Basin Working Group, 

and restoration of the Lower Ocklawaha River and Rodman Reservoir 

through federal and state agency coordination. 

Not only do stakeholders in the basin share responsibilities in 

achieving water quality improvement objectives, they also play a crucial 

role in providing the Department with important monitoring data and 

information on management activities. Significant data providers in the 

basin include the Department, Florida LakeWatch, SJRWMD, Florida Fish 

and Wildlife Conservation Commission (FWC), Orange County, Alachua 

County, Lake County, Polk County, U.S. Army Corps of Engineers 

(USACOE), U.S. Geological Survey (USGS), and U.S. Forest Service 

(USFS). 

During the next few years, considerable data analysis will be done to 

establish TMDLs for impaired waters in the Ocklawaha Basin, establish 

the initial allocations of pollutant load reductions needed to meet those 

TMDLs, and produce a Basin Management Action Plan, or B-MAP, to 

reduce the amount of pollutants that cause impairments. These activities 

depend heavily upon the active participation of the water management 

districts, local governments, businesses, and other stakeholders. The 

Department will work with these organizations and individuals to 

undertake or continue reductions in the discharge of pollutants and achieve 

the established TMDLs for impaired waterbodies. 

U.S. Environmental Protection Agency Review 

of Florida’s Amended Section 303(d) List 

On June 11, 2003, the EPA released a Decision Document based on its 

review of the Department’s amendments to Florida’s 1998 Section 303(d) 

list. The EPA found that the Department’s Group 1 update substantially 

met the intent of Section 303(d) of the Clean Water Act and partially 

approved the submission. 

Applying its own evaluation methodology, the EPA proposed listing 

80 additional waterbody segments/pollutants for public comment by July 

18, 2003. Under this methodology, approximately half of the added waters 

failed to meet water quality criteria for dissolved oxygen, but no causative 

pollutant could be identified. Florida law precludes the Department from 

including such waters on its Verified List of impaired waters until the 

causative pollutant is known. The majority of the remaining waters were 

added to the list based on a different interpretation of the methodology for 

assessing potential impairment for bacteria. The Department agreed to 

apply this alternative methodology when assessing the next group 

(Group 2) of waterbodies for bacteria. 

The consequence of having the EPA add waters to Florida’s Section 

303(d) list is that the EPA would be obligated to propose TMDLs for 

these waters. However, the EPA has proposed assigning a “low” priority 

to these waterbodies, thus providing the Department an opportunity to 

investigate them further. Information on the status of Florida’s amended


11 

Section 303(d) list is available on the EPA’s Web site at 

http://www.epa.gov/region4/water/tmdl/florida/. 

Summary of Findings 

The Department’s Phase 2 assessment shows that 40 waterbodies in 

the Ocklawaha Basin are verified impaired and require the development of 

TMDLs. Impairments are summarized below, by planning unit. Planning 

units are smaller areas within the basin that provide a more detailed 

geographic basis for identifying and assessing water quality improvement 

activities. 

Lake Apopka Planning Unit 

Of the 29 waterbody segments in the Lake Apopka planning unit, 

10 have at least some type of data in the planning and/or verification 

periods, but in many cases the data are insufficient for assessment of 

segments under the Impaired Surface Waters Rule (IWR). Nine segments 

have sufficient data for assessment, and of these, 2 are verified impaired 

for at least one parameter assessed, 5 remain on the Planning List as only 

potentially impaired, and 2 meet standards for all parameters assessed. 

Listed below are the verified impaired segments in the planning unit, 

with the parameters for which they are impaired. 

Gourd Neck Spring Nutrients (Chlorophyll a) 

Lake Apopka 

Pesticides in fish tissue, Nutrients 

(Trophic State Index [TSI]) 

Other potential impairments in the planning unit include high 

metals concentrations, low dissolved oxygen (DO) levels, high unionized 

ammonia and turbidity levels, and poor biological community structure. 

Most of these problems are either directly or indirectly related to excess 

nutrients. The waterbodies in the planning unit that have at least some of 

the indicators of nutrient enrichment include Lake Apopka, Gourd Neck 

Spring, Lake Avalon, Johns Lake, and Black Lake Outlet. 

Palatlakaha River Planning Unit 

Of the 66 waterbody segments in the Palatlakaha River planning 

unit, 38 have at least some type of data in the planning and/or verification 


segments under the IWR. Nineteen segments have sufficient data for 

assessment, and of these, 1 segment is verified impaired for at least 1 

parameter assessed, 9 remain on the Planning List as only potentially 

impaired, and 9 meet standards for all parameters assessed. 

Listed below is the verified impaired segment in the planning unit, 

with the parameters for which it is impaired. 

Palatlakaha River DO, Nutrients (Chlorophyll a)


Other potential impairments in the planning unit include low DO 

levels in several lakes, one potential impairment for lead in Lake Lowery, 

and fish consumption advisories for mercury in fi sh tissue in Lake 

Minnehaha Outlet (previously named Crystal Lake Outlet) and Lake 

Louisa Outlet. 

There are many more waters meeting standards for nutrients in the 

planning unit than there are either potentially or verified impaired for 

nutrients; therefore, elevated nutrients do not appear to be a significant 

problem here. 

Lake Griffin Planning Unit 

Of the 58 waterbody segments in the Lake Griffin planning unit, 31 

have at least some type of data in the planning and/or verification periods, 

but in many cases the data are insufficient for assessment of segments under 

the IWR. Nineteen segments have sufficient data for assessment, and of 

these, 6 are verified impaired for at least 1 parameter assessed, 5 remain on 

the Planning List as only potentially impaired, and 8 meet standards for all 

parameters assessed.

Nutrients are the most pressing water quality concern in the Lake 

Griffin planning unit. Other potential impairments in the planning unit 

include low DO levels in canals, coliform bacteria in Haines Creek Reach, 

turbidity in Lake Griffin, metals in some of the lakes and mercury in fi sh 

tissue as indicated by fish consumption advisories in the Ocklawaha River 

at Sunnyhill Farm and Swim Pond. 

Lake Harris Planning Unit 

Of the 69 waterbody segments in the Lake Harris planning unit, 43 



the IWR. Thirty-two segments have sufficient data for assessment, and of 

these, 12 are verified impaired for at least 1 parameter assessed, 7 remain 

on the Planning List as only potentially impaired, and 13 meet standards 

for all parameters assessed.

It is apparent that nutrients are the major water quality concern in the 

Lake Harris planning unit. Other potential impairments in the planning 

unit include low DO levels in springs, which might be a natural condition, 

as well as high turbidity in Lake Denham; poor biological community 

structure in some of the sloughs, runs, and outlets from lakes and springs; 

and high metals concentrations in a few lakes. 

Marshall Swamp Planning Unit 

Of the 27 waterbody segments in the Marshall Swamp Creek planning 



segments under the IWR. Six segments have sufficient data for assessment, 

and of these, 3 are verified impaired for at least 1 parameter assessed, and 

3 remain on the Planning List as only potentially impaired. There are no 

segments that meet standards for all parameters assessed.

levels in Silver Springs and the Silver River, which might be natural 

conditions, as well as poor biological community structure in Silver 

River and the Ocklawaha River above Daisy Creek, high metals in Lake 

Weir, and fish consumption advisories for mercury in fi sh tissue in the 

Ocklawaha River above Daisy Creek and in Smith Lake. The major water 

quality concerns in the planning unit are reduced DO levels, nutrient 

enrichment, and metals impairments.


Florida Ridge Planning Unit 

Of the 7 waterbody segments in the Florida Ridge planning unit, none 

has any data of any type in the planning or verification periods; therefore, 

they could not be assessed under the IWR. There are several small lakes 

and ponds in the planning unit, particularly in the Noncontributing 

Area west of Lake Wauberg, Orange Lake, Newnans Lake, and Paynes 

Prairie (in the Orange Lake planning unit). Attention should be given 

to collecting data for these lakes to allow characterization of their water 

qualities. 

Rodman Reservoir Planning Unit 

Of the 57 waterbody segments in the Rodman Reservoir planning 



segments under the IWR. Twenty-three segments have sufficient data for 

assessment, and of these, 2 are verified impaired for at least 1 parameter 

assessed, 9 remain on the Planning List as only potentially impaired, and 

12 meet standards for all parameters assessed. 



Lake Bryant 

Ocklawaha River above Lake 

Ocklawaha 



Other potential impairments in the planning unit include high metals 

concentrations in several lakes and the Rodman Reservoir (also known as 

Lake Ocklawaha), as well as low DO concentrations and poor biological 

community structure in some lakes, creeks and river segments. 

Orange Creek Planning Unit 

Of the 105 waterbody segments in the Orange Creek planning unit, 53 



the IWR. Thirty-six segments have sufficient data for assessment, and of 

these, 14 are verified impaired for at least 1 parameter assessed, 7 remain 

on the Planning List as only potentially impaired, and 15 meet standards 

for all parameters assessed.

Chapter 1: Introduction 

Purposes and Content of the Assessment 

Report 

The Department is implementing a statewide watershed management 

approach for restoring and protecting water quality and addressing Total 

Maximum Daily Load (TMDL) Program requirements. Under Section 

303(d) of the federal Clean Water Act and the 1999 Florida Watershed 

Restoration Act (FWRA) (Chapter 99-223, Laws of Florida), TMDLs 

must be developed for all waters that do not meet their designated uses 

(such as drinking water, recreation, and shellfish harvesting) and are thus 

defined as impaired. 

TMDLs will be developed, and the corresponding reductions in 

pollutant loads allocated, as part of the watershed management approach, 

which rotates through the state’s 52 river basins over a 5-year cycle. 

Extensive public participation from diverse stakeholders in each of these 

basins is crucial in all phases of the cycle. 

A Status Report published during Phase 1 of the watershed 

management cycle provided a Planning List, or preliminary identification, 

of potentially impaired waterbodies in the Ocklawaha Basin. A copy of the 

report is available at http://www.dep.state.fl.us/water/tmdl/stat_rep.htm. 

This Assessment Report, which updates the information in the Status 

Report, incorporates data collected from the Department’s strategic 

monitoring efforts and those gathered from other agencies and groups 

during Phase 2 of the watershed cycle. The report contains a Verifi ed List of 

impaired waters, required by the FWRA and Section 303(d) of the federal 

Clean Water Act, for which TMDLs will be developed and implemented 

(see Noteworthy for a description of the Assessment Report’s contents, by 

chapter). Pending approval by the U.S. Environmental Protection Agency 

(EPA), this list will serve as the 2002 303(d) list of impaired waters for the 

basin. The 1998 303(d) list is currently the most recently EPA-approved 

list. 

Based on the Department’s assessment results, there are 40 waterbodies 

or waterbody segments in the Ocklawaha Basin that are verified impaired 

for one or more parameters. TMDLs will be developed for these waters, 

unless the impairment is documented to be a naturally occurring condition 

that a TMDL cannot abate or where a management plan is already in place 

that is expected to correct the problem. 

This report is intended for distribution to a broad range of potential 

stakeholders, including decision makers in federal, state, regional, tribal, 

and local governments; public and private interests; and individual citizens. 

The Verified List is required by Subsection 403.067(40], Florida 

Statutes (F.S.), and Section 303(d) of the federal Clean Water Act. The 

Total Maximum 

Daily Load 

The maximum amount of a 

given pollutant that a waterbody 

can assimilate and 

remain healthy, such that all 

of its designated uses are 

met.

23 

Department has adopted the Verified List of impaired waters in accordance 

with the FWRA and the Identification of Impaired Surface Waters Rule 

(Rule 62-303, Florida Administrative Code [F.A.C.]). The EPA also 

approved this list as the current 2002 303(d) list of impaired waters for the 

basin, so called because it is required under Section 303(d) of the Clean 

Water Act. 

The first 303(d) list, which was required by the EPA in 1998, is to 

be amended annually to include basin updates. Florida’s 1998 303(d) list 

included a number of waterbodies in the Ocklawaha Basin. Tables 3.5 

through 3.12 in Chapter 3 list these waters, by planning unit. 

This Assessment Report follows the EPA’s guidance for meshing 

Clean Water Act requirements for Section 305(b) water quality reports 

and Section 303(d) lists of impaired waters. This integrated water quality 

assessment is used to identify the status of data sufficiency, the potential for 

impairment, and the need for TMDL development for each waterbody or 

waterbody segment in the basin. 

A description of the legislative and regulatory background for TMDL 

development and implementation through the watershed management 

approach, and a brief explanation of the TMDL Program, are available 

in Appendix A. Background information on the Department’s TMDL 

Program, the process of TMDL development and implementation, lists 

of impaired and potentially impaired waters, and assessments for other 

parts of the state are available at http://www.dep.state.fl.us/water/tmdl/ 

index.htm. 

Stakeholder Involvement 

The FWRA requires the Department to work closely with stakeholders 

to develop and implement TMDLs. In addition, the Allocation 

Technical Advisory Committee report discussed in Chapter 5 includes 

recommendations that rely heavily on stakeholder involvement. 

Stakeholder involvement in the TMDL process will vary with each 

phase of implementation to achieve different purposes (Table 1.1). 

The Department will work cooperatively with a number of key 

stakeholders to develop, allocate, and implement TMDLs in the 

Ocklawaha Basin. These stakeholders include the following: 

Alachua County 

Alliance for Water Resources 

Cities/Chambers of Commerce

to undergo a preliminary assessment in 2000 and is the subject of this 

Assessment Report. A preliminary assessment of the Middle St. Johns 

River (Group 2) Basin was carried out in 2001. Similarly, a preliminary 

assessment of the Upper St. Johns River (Group 3) Basin was begun in 

2002, and preliminary assessments of the Kissimmee River (Group 4) 

Basin and the Indian River Lagoon (Group 5) Basin will be initiated in 

2003 and 2004, respectively. In 2005, the cycle will resume with the 

Ocklawaha (Group 1) Basin.

proposed management activities; identify 

management objectives and issues of concern; 

develop a Strategic Monitoring Plan; 

and produce a preliminary Status Report 

that includes a Planning List of potentially 

impaired waters. 

Cooperative efforts between the Department 

and local stakeholders to collect 

additional data; get data into STORET; 

complete water quality assessment; 

produce a final Assessment Report that 

includes a Verified List of impaired waters 

for Secretarial adoption; and provide an 

opportunity for stakeholders to document 

reasonable assurance (for Department 

review) that existing management plans 

and projects are adequate to restore water 

quality without the establishment of a 

TMDL. 

Coordination with stakeholders to discuss 

TMDL model framework, including model 

requirements, parameters to be modeled, 

model endpoints, design run scenarios and 

preliminary allocations; communication of 

science used in the process; public workshops 

for rule adoption of TMDLs. 

Broad stakeholder participation in developing 

a Basin Management Action Plan 

(B-MAP) (including detailed allocations and 

implementation strategies), incorporating 

it into existing management plans where 

feasible; public meetings during the planning 

process. 

Emphasis on implementing the B-MAP, 

other voluntary stakeholder actions, and 

local watershed management structures; 

Department will continue to provide technical 

assistance, fulfill oversight responsibilities, 

and administer National Pollutant 

Discharge Elimination System (NPDES) 

point and nonpoint source permits.

Chapter 2: Basin Overview 

Basin Setting 

The Ocklawaha Basin covers 2,769 square miles of the central to 

northern portion of Florida’s peninsula, from the Green Swamp near 

Haines City north to Gainesville. The largest tributary basin of the St. 

Johns River, it is defined as the area within U.S. Geological Survey (USGS) 

hydrologic unit code (HUC) 03080102. 

The Ocklawaha Basin is composed of two hydrologically distinct 

parts. The Ocklawaha River and its associated lakes and tributaries occupy 

the eastern half and northern portion of the basin, comprising a defi ned, 

connected surface drainage pattern. Interstate 75 approximates the western 

boundary of the surface drainage system. Dominant features of the surface 

drainage system are large, connected lakes and wetlands. This part of the 

basin has distinct subbasins, including, from south to north, Lake Apopka, 

Palatlakaha River and Clermont Chain of Lakes, Upper Ocklawaha 

Chain of Lakes, Ocklawaha River, and Orange Creek. Discharges and 

water levels are regulated for the Ocklawaha River and most of the large 

connected lake chains. The Ocklawaha River proper emerges out of Lake 

Griffin in the Upper Ocklawaha Chain of Lakes and flows north for about 

96 miles before joining the St. Johns River (Florida Department of Natural 

Resources [FDNR], 1989). 

The area west of Interstate 75, the Florida Ridge, is the second 

hydrologic part of the basin. It is largely an internally drained area 

with little developed, connected surface hydrography, but rather a welldeveloped 

ground water or subsurface flow system. Primary discharge 

points for ground water are Silver Springs to the Ocklawaha River and 

Rainbow Springs to the Withlacoochee River. 

The basin is politically and socially complicated and diverse. Moving 

from south to north, parts of Polk, Orange, Lake, Sumter, Marion, Levy, 

Putnam, and Alachua Counties are included. Major cities are Gainesville 

(Alachua County), Ocala (Marion County), Apopka and Winter Garden 

(Orange County), and the cluster of Lady Lake, Leesburg, Eustis, Mt. 

Dora, Tavares, and Clermont (Lake County). A large urban center, the 

city of Orlando, is just to the southeast of the basin, but exerts pressure on 

it through population growth, urban sprawl, and competition for water 

resources. 

Each county in the basin has unique characteristics. Most of the basin 

contained in Polk County lies within the Green Swamp. Orange County 

was historically noted for citrus and muck farming around Lake Apopka. 

Over the past two decades, the county has been transformed into an everexpanding, 

urbanized area where tourism is a primary industry. Lake


County lives up to its name with 1,440 lakes. Historically, agriculture 

(muck farms) and citrus were large contributors to Lake County’s economy. 

More recently, tourism and residential development, spurred by people 

moving from the Orlando area, and retirees have become important 

economic contributors. Marion County, another rapidly growing county, 

is known for thoroughbred racehorses and the glass-bottomed boats at the 

Silver Springs attraction. Levy and Putnam Counties are generally rural in 

character. Rodman Reservoir, also called Lake Ocklawaha, in Putnam and 

Marion Counties, is a nationally recognized recreational fishery. Alachua 

County is home to the University of Florida in Gainesville, Paynes Prairie 

State Preserve, and the Orange Creek Basin. Lakes in the Orange Creek 

Basin are well known as valuable recreational and commercial fisheries. 

Multiple entities are involved in the management of water resources 

and planning efforts in the basin. Water resource management is the 

responsibility of three water management districts and the Department. 

Most of the basin lies in the St. Johns River Water Management District 

(SJRWMD). The area west of Interstate 75 is within the Southwest 

Florida Water Management District (SWFWMD), except for a small 

northwest corner in the Suwannee River Water Management District 

(SRWMD). Similarly, three Department district offices—Central, 

Northeast, and Southwest—share regulatory jurisdiction. Comprehensive 

planning activities involve the Florida Department of Community Affairs 

and five regional planning councils, along with local governments. 

Regional planning councils include North Central Florida (Alachua 

County), Northeast Florida (Putnam County), Withlacoochee (Marion 

and Sumter Counties), East Central Florida (Lake and Orange Counties), 

and Central Florida (Polk County).

History of Settlement and Water Resource 

Modification 

The Ocklawaha Basin has a long history of use dating back to 

the earliest settlements of the Timucuan Indians. With the arrival of 

European colonists, the river basin provided commercial transportation, 

agricultural and domestic water supplies, and recreation. Raw materials 

such as cypress trees were logged from the Ocklawaha River’s floodplain 

forest. By the late 1880s, the development of tourism, agriculture, and 

commerce was well under way. 

Navigation was an important early function of the Ocklawaha River. 

Steamboats transported citrus, lumber, sea island cotton, sugar, and other 

agricultural commodities to ports on the St. Johns River. They also 

brought tourists and helped make the basin a tourist mecca by the late 

nineteenth century. Tourists visited Silver Springs as early as the 1850s, 

and the Clyde Steamship Company continued to run steamboat trips


29 

Figure 2.1: Geopolitical Map of the Ocklawaha Basin


on the Ocklawaha and Silver Rivers until the 1920s (Mitchell, 1947). 

Navigation still plays a role today, but it primarily supports recreational use 

of the river. 

While agriculture and navigation contributed to the basin’s economic 

growth, they also required significant modification of its hydrology 

and natural systems. Along with urbanization and direct discharges 

of wastewater, many of these modifications contributed to declines in 

water quality, impacts to fish and wildlife, and the loss of natural system 

function; they are now the targets of extensive restoration efforts. 

Water control projects were undertaken primarily to accommodate 

agricultural expansion, but also to allow navigation and later to provide 

flood control for the protection of farms and houses by managing and 

stabilizing water levels. The construction of water control structures and 

canals and the channelization of the Ocklawaha River began in the 1880s. 

Several congressional authorizations of the Rivers and Harbors Act between 

the late 1800s and early 1900s allowed for the dredging and deepening 

of the Ocklawaha River channel. Other modifications to the Ocklawaha 

River proper were the removal of snags, floating islands, and overhanging 

trees and vegetation, as well as the creation of cutoffs at sharp bends. The 

present configuration of control structures was achieved in 1974 with the 

completion of the Four River Basins Project. Authorized in 1962 under 

the Flood Control Act, this project provided for larger structures and the 

deepening of the river channel to provide flood protection and solve water 

control problems. 

As early as 1826, government surveys evaluated the feasibility of 

constructing a canal across Florida to provide a transportation route 

between the Atlantic Ocean and Gulf of Mexico. Interest in the canal 

was rekindled during World War II when German submarines became 

a potential threat to American shipping. Construction on the canal 

started in 1964. Included in the project were the construction of Rodman 

Reservoir and the Kirkpatrick and Eureka Dams. These structures were 

completed before President Richard Nixon halted the project in 1971 

because of environmental concerns. The Cross-Florida Barge Canal was 

fully deauthorized in 1991, and the former canal lands became the Cross- 

Florida Greenway. 

Historically, large expanses of wetlands throughout the basin were 

viewed as lands that could be made useful by draining them for agriculture. 

Muck farms were created by the drainage of wetlands around upper basin 

lakes, Orange Lake, and the Ocklawaha River. Drainage exposed rich 

organic soils that were valuable for growing crops. These farmlands were 

actually lower than adjacent waterbodies, which periodically required 

pumping water from the farmlands to adjacent waterbodies. Unfortunately, 

the effluent carried excess nutrients, sediments, and pesticides and has 

contributed to the decline in water quality in the receiving waters for many 

years. Figure 2.2 shows the general historical locations of muck farms in 

the basin. 

The earliest attempts at draining wetlands took place in the 1880s 

and 1890s with the construction of the Apopka–Beauclair Canal, 

which connected Lake Apopka through Lake Beauclair with the Upper


31 

Figure 2.2: General Locations of Historical Muck Farming Areas in the Ocklawaha Basin


Ocklawaha Chain of Lakes. Apopka–Beauclair Lock and Dam were added 

in 1956 to control the level of Lake Apopka. Around 1916 or 1917, under 

pressure from farming interests, the U.S. Congress approved draining parts 

of the Ocklawaha River floodplain to create 5,700 acres of muck farms. 

The river’s channel from Starkes Ferry to the Moss Bluff Lock and 

Dam was abandoned and flow was directed to the J. D. Young Canal, 

or C-231 Canal. A second stretch of river north of Moss Bluff was also 

diverted to the C-231 Canal. In total, more than 15 miles of river channel 

were abandoned to create Sunnyhill and Ocklawaha Farms. 

In 1925, a lock and dam were constructed on the Ocklawaha River 

at Moss Bluff to regulate water levels in the river and Lake Griffi n. In 

southern Alachua County, Shands Dike was constructed in the 1930s 

on the eastern side of Orange Lake to isolate wetlands and drain them 

for agricultural use. An additional 6,500 acres of the expansive sawgrass 

marshes north of Lake Griffin (part of Emeralda Marsh) and wetlands 

adjacent to Lake Harris and Lake Minneola were also converted to muck 

farms. Burrell Lock and Dam were constructed in the 1950s on Haines 

Creek to stabilize water levels in Lakes Eustis, Dora, Beauclair, and Harris 

to provide optimum levels for agricultural water supply and improve 

navigation. 

Early attempts at muck farming in the basin were not very successful. 

Large-scale muck farming began in the 1940s and 1950s, with the fi rst 

nutrient-rich discharges from Lake Apopka muck farms in 1942. The total 

acreage in muck farms was at its highest in the 1980s. 

Surface Water Resources 

The Ocklawaha Basin contains numerous surface waterbodies. Surface 

waters, including lakes, streams, wetlands, and springs, occupy 435,195 

acres, or about 24 percent of the total basin area. This section delineates 

the basin’s hydrology, describes the movement and management of water 

in the basin, briefly describes the major characteristics of surface waters 

that influence water quality in the basin, and describes surface water 

classifications and special designations. A more detailed discussion in 

Chapter 3 provides information on each planning unit. 

Hydrology and Water Management 

The surface drainage system of the Ocklawaha Basin begins 

in the Green Swamp near Haines City and the Lake Apopka Basin. 

Figure 2.3 shows the major features of this drainage system. Figure 2.4 

depicts schematically the movement and direction of water through the 

basin. 

Four other river basins share the Green Swamp as their headwater: 

Hillsborough, Withlacoochee, Peace, and Kissimmee. 

The Ocklawaha River begins as a discharge from Lake Griffi n and the 

Upper Ocklawaha Chain of Lakes. Water enters the Upper Ocklawaha 

Chain of Lakes from two different upstream pathways, the Palatlakaha 

River and Lake Apopka. The Ocklawaha River as a defined river channel


33 

Figure 2.3: Hydrography of the Ocklawaha Basin


Figure 2.4: Schematic of Water Movement through the Ocklawaha Basin


35 

begins as an outflow from Lake Griffi n and flows northward to where it is 

impounded as Rodman Reservoir, also known as Lake Ocklawaha. From 

there it makes a sharp right turn before joining the St. Johns River near 

the town of Welaka. The river travels approximately 96 miles from Lake 

Griffin to the St. Johns River (FDNR, 1989). As the Ocklawaha River 

flows downstream, it receives primary additional drainage from its Silver 

River and Orange Creek tributary basins before discharging to the St. 

Johns River. 

Chains of large connected lakes are prominent surface features of the 

basin. Within a chain of lakes, water quality problems that occur in one 

lake can be easily transferred to the other lakes. For example, many of 

the problems experienced by Lakes Beauclair and Dora result from the 

discharge of degraded water from Lake Apopka through the Apopka– 

Beauclair Canal. 

Palatlakaha River Basin 

The Palatlakaha River Basin covers approximately 280 square miles 

and stretches 48 miles from south to north (Wicks, 1982). From its 

southernmost end to Lake Louisa, it is confi ned by parallel sand ridges 

(Lake Wales to the east) and is only two to four miles wide. Stream 

channels in the southern part of the Palatlakaha River are not deep or well 

defined, and much of their drainage is through wide, shallow swamps. 

The headwater of the Palatlakaha River is Lake Lowery and a group of 

interconnected lakes (Tower Lake, Lake Bonnett, and Lake Hammock) and 

marshes near Haines City (Davis, 1982). Drainage between Lake Lowery 

and Lake Louisa is through the Little and Big Creek Basins. 

Green Swamp Run captures the southern part of Big Creek’s drainage 

between Lake Lowery and the Polk–Lake County line. Big Creek, 

including Green Swamp Run, drains about 70 square miles and covers a 

distance south to north of about 25 miles (Pride et al., 1966). Big Creek 

discharges to Lake Louisa, the uppermost lake in what is commonly called 

the Clermont Chain of Lakes. 

Little Creek drains the basin west of Big Creek, an area of about 15 

square miles, before discharging to Lake Louisa. The current Little Creek 

drainage area is smaller than its historical area because about 60 square 

miles of its southern drainage was diverted to the Withlacoochee River 

Basin by interceptor canals dug in about 1948 or 1949 near the Polk-Lake 

County line (as interpreted by Pride et al., 1966). 

The Palatlakaha River flows northward from Lake Louisa, connecting 

the Clermont Chain of Lakes before discharging to Lake Harris in the 

Upper Ocklawaha Chain of Lakes. The Clermont Chain of Lakes contains 

15 lakes; the largest are Minneola, Minnehaha, and Louisa. 

The Lake County Water Authority manages the water levels on the 

Palatlakaha River and the Clermont Chain of Lakes so that water levels are 

low during the wet season and raised during the dry season. An earthen 

dam (Cherry Lake Dam) at the outlet of Cherry Lake maintains the 

elevation of upstream lakes during prolonged periods of dry weather and 

provides irrigation water for citrus groves. Water levels in Cherry Lake 

are kept between 96.8 and 96 feet above mean sea level (MSL). Water


Regulation 

Schedule for 

Palatlakaha River 

Structures 

The regulation schedule for 

the Palatlakaha River structures 

is as follows: Villa City, 

94.8–94; M-6, 92–91; M-5, 

89.5–88.75; M-4, 85–83.75; 

and M-1, 71 feet above 

MSL (Lake County Water 

Authority, 2001). 

discharge from the Palatlakaha River into Lake Harris is regulated through 

a series of five gated dams (Villa City, M-6, M-5, M-4, and M-1) (see 

sidebar). 

Lake Apopka and Upper Ocklawaha Chain of Lakes 

In addition to the Palatlakaha River Basin, water enters the Upper 

Ocklawaha Chain of Lakes from the Lake Apopka Basin. About 

half of the flow in the Upper Ocklawaha Chain of Lakes comes from 

the Palatlakaha River and Lake Apopka Basins. Most flow from the 

Lake Apopka Basin comes directly from Lake Apopka through the 

Apopka–Beauclair Canal. About 60 other landlocked lakes are scattered 

throughout the 187-square-mile Lake Apopka Basin, but these are 

generally not connected, except possibly during periods of high rainfall 

(SJRWMD, 2001). Apopka Spring, in the Gourd Neck area of Lake 

Apopka (southwest corner), supplies about 30 percent of the lake’s average 

net outflow (Bush, 1974). Water flows north from Lake Apopka through 

the Apopka–Beauclair Canal and enters Lake Beauclair in the Upper 

Ocklawaha Chain of Lakes. Since 1956, the Apopka–Beauclair Lock and 

Dam has controlled flows and lake levels, maintaining the elevation of 

Lake Apopka between 64.3 and 68.4 feet above MSL (SJRWMD, 2001). 

Historically, during periods of high water, the lake may have drained to the 

northwest through Double Run Swamp into Little Lake Harris. 

The Upper Ocklawaha Chain of Lakes Basin contains the connected 

Lakes Beauclair, Dora, Eustis, Harris, Yale, Griffin, and Little Lake Harris 

and associated wetlands. The Ocklawaha River begins as a recognizable 

channel out of the north end of Lake Griffi n. Water from Lake Beauclair 

flows directly into Lake Dora, which then drains into Lake Eustis through 

the Dora Canal. Lake Harris is connected to Lake Eustis through the 

Dead River. Lake Eustis discharges to Lake Griffi n through Haines Creek, 

and Lake Yale discharges into Lake Griffi n through the Lake Yale Canal. 

Control structures in the Upper Ocklawaha Chain of Lakes and Lake 

Apopka, operated by the SJRWMD, limit the range of fluctuation of lake 

levels for flood control and navigation. Regulation schedules are seasonal, 

but are opposite of what should be the natural seasonal fluctuations in 

water levels. Lake levels are at their lowest at the start of the summer 

wet season to provide flood storage and highest at the start of the dry 

season. The stabilization of lake levels limits the flushing of the lake 

to remove sediments and nutrients and reduces the amount of wetland 

habitat along shorelines. The Burrell Lock and Dam in Haines Creek 

controls water levels on Lake Eustis and to a lesser extent on Lakes Harris, 

Dora, Beauclair, and Little Lake Harris. The elevation of Lake Eustis is 

maintained between 62 and 63.5 feet above MSL. Moss Bluff Lock and 

Dam, downstream of Lake Griffin, controls water levels on Lake Griffin 

and the Ocklawaha River and also influences water levels in Lake Yale. 

Levels in Lake Griffin are maintained between 58 and 59.5 feet above MSL 

(Fulton, 1995).


37 

Ocklawaha River Basin and Silver Springs 

The Ocklawaha River from Moss Bluff to its confluence with the 

St. Johns River receives drainage from about 1,890 square miles, and 

includes drainage from Marshall Swamp and Lake Weir, Silver Springs, 

Orange Creek (described in the next section), and smaller tributary basins. 

Downstream of Lake Griffi n, the river channel from Starkes Ferry to the 

Moss Bluff Lock and Dam and northward from Moss Bluff was abandoned 

and flow was directed to the J. D. Young Canal, or C-231 Canal. 

Silver River enters the Ocklawaha River near State Road 40 east of 

Ocala. It receives its flow from several spring boils known collectively 

as Silver Springs. The ground water contributing area for Silver Springs, 

as delineated by the SJRWMD from the potentiometric surface of the 

Upper Floridan aquifer during September 1997, is approximately 1,100 

square miles in size (Figure 2.5) and extends beyond the Ocklawaha 

Basin’s surface water boundaries (Phelps, 1994). The Silver River connects 

the internally drained Florida Ridge portion of the basin to the Ocklawaha 

River through subsurface or ground water flow. The boundaries of the 

ground water contributing area depend on the potentiometric surface of the 

Floridan aquifer and change seasonally. 

Ground water flow to the west of the Silver Springs contributing area 

generally discharges to Rainbow Springs in the Withlacoochee River Basin. 

There is no connected surface flow to the Ocklawaha River from the area 

west of Silver Springs. The Silver Springs/Silver River complex adds a 

substantial volume of water to the Ocklawaha River, influencing its quality. 

Farther downstream, the construction of Rodman Reservoir as part 

of the Cross-Florida Barge Canal impounded about 15 miles of the river. 

The Cross-Florida Barge Canal project was begun in 1964 with the 

construction of two dams, Eureka and Rodman (later renamed Kirkpatrick 

Dam). These dams were completed before the entire project was suspended 

in 1971 by the Executive Order of President Richard Nixon, and both 

remain intact today. The Cross-Florida Barge Canal, including the 

Buckman Lock, connects Rodman Reservoir with the St. Johns River. The 

Department manages the Buckman Lock and Dam and Kirkpatrick Dam 

as part of the Cross-Florida Greenways State Recreation and Conservation 

Area. The natural braided stream channel of the Ocklawaha River still 

receives flow from Rodman Reservoir through Kirkpatrick Dam and 

discharges to the St. Johns River at its mouth just south of the Cross- 

Florida Barge Canal. 

Potentiometric 

Surface 

Potentiometric surface is the 

level to which water in a confined 

aquifer (aquifer under 

pressure) will rise in a tightly 

cased well. If the potentiometric 

surface of the aquifer 

is above the land surface, an 

artesian or free-flowing well 

will result. The water table 

is the potentiometric surface 

for an unconfined aquifer. 

Orange Creek Basin 

The Orange Creek Basin covers about 600 square miles and comprises 

6 major subbasins: Hogtown Creek, Paynes Prairie, Newnans Lake, 

Lochloosa Lake, Orange Lake, and Orange Creek. In general, water moves 

from Newnans Lake to Paynes Prairie and Orange Lake, from Lochloosa 

Lake into Orange Lake, and then from Orange Lake into Orange Creek. 

Orange Creek is the sole surface water outlet to Rodman Reservoir 

from this basin. It has two main tributaries, Lochloosa Slough and 

Little Orange Creek, in addition to the discharge from Orange Lake. 

Discharge from Orange Lake to Orange Creek is through a fi xed notch

the Upper Floridan Aquifer, September 1997)


39 

weir constructed in 1963 at U.S. Highway 301, although control of water 

elevation is minimal. Some surface flow is lost to Orange Sink in Orange 

Lake, depending on ground water levels. 

The drainage from Newnans Lake to Orange Lake was created with 

the construction of Camps Canal in 1927 and in effect connected the 

Newnans Lake and Lochloosa Lake subbasins. Before Camps Canal 

was built, water from Newnans Lake flowed into Prairie Creek; from 

there it moved as sheetflow across Paynes Prairie to Alachua Lake before 

discharging into Alachua Sink. Water is now discharged from Camps 

Canal through a weir to Paynes Prairie under SJRWMD 

Section 40C-2.302, Florida Administrative Code (F.A.C.) Paynes Prairie 

State Preserve staff manage the weir. On annual average, 45 percent of 

the flow from Newnans Lake is allocated to Paynes Prairie, while the 

remainder flows into Orange Lake. A dam was constructed in 1966 on 

Prairie Creek to control outflow from Newnans Lake, but it has since 

been removed. When water levels are high, Lochloosa Lake can discharge 

directly to Orange Creek through Lochloosa Slough. 

Hogtown Creek and Paynes Prairie are closed basins and do not 

directly contribute flow to the Ocklawaha River. Both Hogtown Creek 

and Paynes Prairie receive stormwater runoff from urbanized areas of 

Gainesville, which they discharge to the Floridan aquifer through Haile 

Sink and Alachua Sink, respectively. 

Weir 

A small dam in a river or 

stream to raise the water 

level or divert its flow. 

Streams 

Streams occupy 2,437 acres, or 0.14 percent of the basin area. Because 

of its age, the Ocklawaha has a wide river valley, up to a mile wide in 

places (FDNR, 1989). Dams and channelization have altered the natural 

attributes of the Ocklawaha River. It is a sand-bottomed river (Nordlie, 

1990) that is generally characterized as chemically circumneutral to slightly 

acidic, with low to moderate buffering capacities. A large quantity of 

hard water coming from Silver Springs influences the general chemical 

characteristics of the Ocklawaha River. 

Other stream types in the basin are canals, calcareous streams, and 

swamp and bog streams. Canals typically have the same water quality 

characteristics as their connecting surface waters. Calcareous streams are 

generally spring runs, such as Silver River and Helena Run, receiving their 

water from ground water. Bottom materials are typically sand, clay, and 

limestone. They are usually clear and well buffered, with fairly constant 

temperatures. Swamp and bog streams originate in swamps and marshes 

and have slow velocities. Their water quality is characterized as slightly to 

highly acidic, poorly buffered, and colored. 

Lakes, Reservoirs, and Ponds 

There are 1,960 lakes and 1,449 artificial impoundments or reservoirs 

in the Ocklawaha Basin, making it a lake-dominated basin. The vast 

majority of these features are less than 10 acres (Figure 2.6). Natural 

lakes and ponds occupy 142,215 acres, or 8 percent of the basin area. 

Impoundments cover 11,452 acres, or 0.64 percent of the basin area; most 

of that is Rodman Reservoir. Nineteen of the state’s 100 largest lakes and 

reservoirs are in the basin (Table 2.1).

Many lakes in the Ocklawaha Basin formed when carbonate 

sediments, dissolved by ground water, formed cavities that collapsed to 

form surface depressions or sinkholes. Lakes also originated from relict 

sea bottom depressions and erosion and sedimentation-processed rivers 

(Edmiston and Myers, 1983). Topographic divides enclose many solution 

lakes, and drainage into them either evaporates or percolates downward to 

the ground water system. Smaller human-made lakes and ponds include 

mining or “borrow” pits, cooling ponds, and stormwater retention ponds. 

Geologic history, biology, soils, and surrounding land uses influence 

the physical characteristics and water quality of lakes in the basin. 

Lakes vary from acidic, clear, and low in productivity (oligotrophic) to 

alkaline and high in productivity (eutrophic). Lake ecoregions provide a 

spatial framework for describing and defi ning the physical and chemical 

characteristics of lakes in the basin. Out of 47 lake ecoregions in Florida, 

16 are in the Ocklawaha Basin (Griffith et al., 1997). Lake ecoregions are 

described in Appendix B. 

Lakes vs. Wetlands 

Lake statistics were derived 

from 1995 land use data. 

Only surface features classified 

by Florida land use codes 

indicating open water were 

included. Large surface features 

classified as wetlands 

on the 1995 land use maps 

may be classified as lakes on 

other maps. 

Wetlands 

Wetlands comprise 279,000 acres, or about 15.69 percent, of the total 

basin area. Wetlands are most prominent in the Upper Ocklawaha and 

Orange Creek Basins and less evident in the Florida Ridge. Numerous 

small marshes occupied the landscape around the Ocklawaha River before 

they were submerged by the construction of Rodman Reservoir (Kushlan, 

1990) (Figure 2.3). Wetlands provide important habitat for many of 

the basin’s rare and listed plant and animal species, in addition to more

common species. Swamps and marshes surrounding lakes and rivers 

provide important nesting areas for eagles, osprey, sandhill cranes, and 

wading birds; the basin also contains several large rookeries. 

In addition to wetlands that comprise the littoral and riparian zones 

of lakes and rivers, there are numerous large, well-developed wetland 

systems in the Ocklawaha Basin. The most notable wetland, because of its 

size, is the Green Swamp. This swamp, the headwater of the Palatlakaha 

River, occupies 544,000 acres of intermixed marshland, sandhills, forest, 

rivers, and lakes, although only a portion of the total acreage is in the 

basin. Another large, prominent wetland is Paynes Prairie, a 19,000-acre 

wet prairie south of Gainesville. It is an important habitat for resident and 

migratory sandhill cranes. The existence of the prairie is closely connected 

with flows to and from the Floridan aquifer via Alachua Sink. Historically, 

Alachua Sink has variously been a lake, wetland, and dry prairie. From 

1870 to 1892, Alachua Sink was plugged, and ferries and steamboats 

operated on Alachua Lake. 

Other large wetland systems are Marshall Swamp, Emeralda Marsh 

and North Lake Griffin Marsh, Okahumpka Marsh, and wetlands associated 

with Orange Lake and the River Styx. Table B.2 in Appendix B 

contains more complete descriptions of these and other wetlands in the 

basin. 

Springs 

As is typical of karst topography, numerous springs are found 

throughout the basin. Springs form when ground water flows out to the 

surface through a natural opening in the ground. Springs are generally 

aggregated near or around Lake Apopka, Lake Harris, Orange Creek Basin, 

and Rodman Reservoir (Figure 2.3). Table 2.2 lists the known springs 

in the basin and provides, if available, the estimated amount and location 

of their discharges (Rosenau et al., 1977). The largest spring by discharge 

is Silver Springs, a first-order magnitude spring (greater than 65 million 

gallons per day of flow). Most identified springs originate as ground water 

discharges from the Florida aquifer and have water quality similar to 

ground water. 

Surface Water Quality Classifications 

Florida’s water quality standards program, the foundation of the state’s 

program of water quality management, designates the “present and future 

most beneficial uses” of the waters of the state (Subsection 403.061[10], 

Florida Statutes [F.S.]). Water quality criteria for surface water and ground 

water, expressed as numeric or narrative limits for specific parameters, 

describe the water quality necessary to maintain these uses. Florida’s 

surface water is classified using the following five designated use categories: 

Class I 

Class II 

Class III 

Class IV 

Potable water supplies 

Shellfi sh propagation or harvesting 

Recreation, propagation, and maintenance of a healthy, 

well-balanced population of fi sh and wildlife 

Agricultural water supplies

Class V 

Navigation, utility, and industrial use (there are no state 

waters currently in this class) 

All surface waters (including wetlands) in the Ocklawaha Basin are 

designated as Class III in accordance with Rule 62-302, F.A.C. The 

Green Swamp was also designated as an Area of Critical State Concern (see 

Noteworthy) in 1979, per Section 308.0551, F.S. 

Part of the Ocklawaha River and its tributaries in Marion County were 

designated an aquatic preserve on October 1, 1989. The aquatic preserve 

includes almost 20 miles of the middle reach of the Ocklawaha River, 

extending from County Road 312 downstream to the Cross-Florida Barge 

Canal property and the entire Silver River. 

Special Designations 

Outstanding Florida Waters 

Many waters in the basin have been given additional protection 

through designation as Outstanding Florida Waters (OFWs) (Figure 2.7). 

OFWs are designated for “special protection due to their natural attributes” 

(Section 403.061, F.S.). These waters are listed in Section 62-302.700, 

F.A.C. The intent of an OFW designation is to maintain ambient water 

quality, even if these designations are more protective than those required 

under the waterbody’s surface water classification. Most OFWs are 

associated with managed areas in the state or federal park system, such as

44 



Area of Critical State Concern 

Noteworthy 

Per Section 380.05, F.S., the 

Florida Department of Community 

Affairs (DCA) may recommend 

to the Governor and 

Cabinet specific areas of critical 

state concern, which are adopted 

by rule. Areas of Critical State 

Concern are designated for 

resources containing, or having a 

significant impact upon, environmental 

or natural resources of 

regional or statewide importance. 

The DCA includes in its recommendations 

the dangers that 

would result from uncontrolled 

or inadequate development of 

the area and the advantages 

that would be achieved from 

the development of the area in a 

coordinated manner; a detailed 

boundary description of the 

proposed area; specific principles 

for guiding development 

within the area; an inventory of 

lands owned by the state, federal, 

county, and municipal governments 

within the proposed area; 

and a list of the state agencies 

with programs that affect the 

purpose of the designation. 

Considerations in designating 

an Area of Critical State Concern 

include, but are not limited to, the 

following: 

• Whether the economic and/or 

ecological values of the area 

are of substantial regional or 

statewide importance. 

• Whether the area is a designated 

critical habitat of any 

state or federally designated 

threatened or endangered 

plant or animal species. 

• Whether the area is inherently 

susceptible to substantial 

development due to its 

geographic location or natural 

aesthetics. 

• Whether any existing or 

planned substantial development 

within the area will 

directly, significantly, and 

deleteriously affect any or all 

of the environmental or natural 

resources of the area that 

are of regional or statewide 

importance. 

• Whether the area is associated 

with events that have made a 

significant contribution to the 

history of the state or region, 

or will likely yield information 

important to the prehistory or 

history of the state or region.

aquatic preserves, national seashores, or wildlife refuges. Other OFWs may 

also be designated as “Special Waters” based on a finding that the waters are 

of exceptional recreational or ecological significance and are identified as 

such in Rule 62-302, F.A.C. 

The designation means that any new discharge requiring a Department 

or water management district permit (wastewater or stormwater discharges, 

for example) must meet higher water quality standards, with some 

exemptions. Generally, permits cannot be issued for new direct discharges 

of pollutants into an OFW that would lower existing water quality. New 

indirect pollutant discharges (e.g., discharges to tributaries or adjacent 

waters) also must not significantly degrade the OFW. There are certain 

exemptions to these rules for activities intended to enhance public use of 

the waterbody. Legal discharges that existed at the time of designation are 

“grandfathered” and are not affected by an OFW designation, provided 

there is no change in what was permitted as a discharge. 

Activities requiring an Environmental Resource Permit from a water 

management district or the Department can be affected by an OFW 

designation. Surface water management systems (primarily stormwater) 

with direct discharges to an OFW must meet additional design and 

performance criteria to achieve at least a 95 percent pollutant load 

reduction. Activities that do not require Department permits, such as boat 

speeds, fishing, river setback ordinances, and docks smaller than 500 square 

feet, are not affected by an OFW designation, but may be regulated at a 

local level. Table 2.3 lists by county the areas in the Ocklawaha Basin that 

have been designated as OFWs. There are no OFWs in Sumter, Polk, or 

Orange Counties that are within the basin’s boundary. 

The OFWs of primary importance (e.g., those at greatest risk, largest 

size, etc.) are the “special waters” OFWs, including the Ocklawaha River, 

Silver River, Orange Lake, Lochloosa Lake, and the Clermont Chain of 

Lakes. For these OFWs, the landward extent of the OFW designation 

is the Department’s jurisdictional (wetland) limit. Other OFWs exist 

for various managed areas, such as state preserves and Conservation and 

Recreation Lands (CARL) acquisitions; the OFW designation only applies 

to waters within the managed area boundary. 

Surface Water Improvement and Management Priority Waters 

In 1987, the Florida legislature created the Surface Water Improvement 

and Management (SWIM) Program to restore waterbodies. The state’s 

five water management districts work with federal, state, and local 

governments and the private sector to develop and implement SWIM 

plans to restore damaged ecosystems, prevent pollution from runoff and 

other sources, and educate the public. The initial legislation identified 

six priority waterbodies, including Lake Apopka. (The other five SWIM 

waterbodies were Tampa Bay, Indian River Lagoon, Biscayne Bay, Lower 

St. Johns River, and Lake Okeechobee.) The Upper Ocklawaha River was 

also designated a SWIM priority water in 1989. The section on “Major 

Programs and Projects” later in this chapter discusses the SWIM plans 

for Lake Apopka and the Upper Ocklawaha River in greater detail.

The Ocklawaha River State Aquatic Preserve largely covers the same area as the Ocklawaha River “special 

waters” OFW designation. There is some overlap elsewhere with other waterbodies, such as Silver River 

State Park and the Silver River “special waters” OFW designations.

OFW effective dates are for the original date of designation. When additions in an area are made to an existing 

OFW, the baseline year for these additions reverts back to the original date of designation.


Minimum Flows and Levels 

Under the District Water Management Plan (DWMP) for the 

SJRWMD, a number of waters in the Ocklawaha Basin have been 

designated as priorities for the development of minimum flows and levels 

(MFLs). These waterbodies are priorities because consumptive use and 

alterations to their watersheds have reduced or have the potential to 

reduce the amount and timing of surface water being delivered. Projected 

increases in withdrawals also could reduce future discharges. The 

SJRWMD must determine each water’s MFL, to help determine the 

amount of water that is available for human use from a particular source. 

Under the Florida Water Resources Act (Section 373, F.S.), an MFL is the 

limit at which further water withdrawals will cause significant harm to the 

water resources of the area and the related natural environment. Lakes 

and aquifers have minimum levels. Minimum flows are set for rivers and 

streams. A list of these waters is available at http://sjr.state.fl.us/programs/ 

index.html under Programs and Projects, Water Resources Planning and 

Monitoring. Waters for which MFLs have been established as of 

March 11, 2003, are listed in Rule 40C-8, F.A.C. 

Ground Water Resources 

Aquifers and Ground Water Usage 

The geologic formation underlying the Ocklawaha Basin is a thick 

sequence of primarily carbonate rocks capped by thin layers of clay, silt, 

and sand sediment (Scott, 1992). Fluctuations in sea level and subsequent 

subareal exposure contributed significantly to deposition of sediments. 

Contained within the carbonate rock are three aquifer systems: the 

Floridan, intermediate, and surficial aquifers (Southeastern Geological 

Society, 1986). 

The Floridan aquifer is the deepest aquifer. It comprises different 

layers and formations of limestone, including the Suwannee Limestone, 

Ocala Limestone, Avon Park Formations, Oldsmar Formation, and part 

of the Cedar Key Formation, in order of shallowest to deepest or oldest. 

The Suwannee Limestone is not found in all parts of the basin. The 

Ocala Limestone generally constitutes the Upper Floridan aquifer, which 

is closest to the surface west of Ocala, near Lake Harris in Lake County, 

and in western Alachua County (as a result of the Ocala Platform). The 

Floridan aquifer supplies most water used for public supply (Fernald and 

Purdum, 1998) and is generally of good quality where chloride, sulfate, 

and total dissolved solid concentrations are below secondary drinking water 

standards. 

In many parts of the basin, an intermediate confining unit separates 

the Floridan aquifer from the surficial aquifer. This unit is composed of 

fine-grained phosphoric sediments of the Hawthorn Formation that retard 

the exchange of water between the surficial and Floridan aquifers. In effect, 

the Hawthorn Formation can act as a confining layer for the Floridan 

aquifer. The Hawthorn Formation is present over much of the eastern 

basin area and is particularly important under the Ocklawaha River. The


49 

Ocklawaha River is structurally lower than the land to the west, and the 

underlying, poorly drained Hawthorn Formation blocks ground water 

flow from the west. The Hawthorn Formation is largely absent in western 

Marion County and west of Gainesville. Where thick enough and beds 

of permeable material are present, the Hawthorn Formation can contain 

an intermediate aquifer system. The intermediate aquifer is used for some 

domestic and agricultural supplies. 

The surficial (nonartesian unconfi ned) aquifer may be used for 

limited domestic supplies. It is highly variable in thickness and consists of 

undifferentiated deposits of silt, clay, and sand (Pride et al., 1966). 

Karst landscape is well developed in parts of the basin, especially 

western Alachua County and western Marion County, with numerous 

faults, fractures, sinkholes, and caverns in the limestone of the Upper 

Floridan aquifer (Puri and Vernon, 1964). Particularly extensive fracturing 

and faulting are found from the Ocklawaha River westward across 

southern Marion County as a result of two geological uplift events, the 

Ocala Platform and Peninsular Arch (Phelps, 1994; Faulkner, 1973) (see 

Noteworthy for a discussion on the geological events). Many of the 

fractures and faults coincide with the course of the Ocklawaha River, and 

the river’s large-angle turns are believed to be at the intersection of fractures 

(Faulkner, 1970). 

Ground Water Recharge and Discharge and Surface Water 

Interactions 

Regionally, ground water in the Floridan aquifer moves across the 

basin from two potentiometric high points located north and south of the 

basin. Ground water from the Keystone High (near Interlachen) in the 

north moves south to southwest toward central Marion County and also 

westward from the Newnans Lake area to the Santa Fe River. Ground 

water in the south, in central Florida, moves out in all directions from a 

potentiometric high point called the Polk High (also called Green Swamp 

High) that extends from approximately central Lake County to southern 

Highlands County. Ground water generally moves in a northerly direction 

from the Polk High across the Ocklawaha Basin. 

Ground water flow converges from the two potentiometric highs to a 

saddle, or low point, in the potentiometric surface of the Floridan aquifer 

in central Marion County. Flow is then directed either east to discharge at 

Silver Springs or southwest and west to Rainbow Springs (Sacks, 1996). 

Locally, ground water in the area surrounding Silver Springs flows toward 

the spring from virtually all directions (Faulkner, 1970). 

Ground water discharges and recharges occur in several ways. The 

surficial aquifer system provides flow for streams and lakes through 

lateral flow or the discharge of ground water as determined by local 

topography. It may also discharge to the Floridan aquifer by downward 

leakage. Ground water drainage divides for the surficial aquifer 

generally coincide with most of the major river surface water drainage 

divides originating from the Green Swamp. Recharge to the surficial 

aquifer system occurs primarily from local rainfall and seepage from

Geological Events That Shaped Ocklawaha Basin 

Noteworthy 

Two geological events shaped 

the subsurface structure of the 

Ocklawaha Basin. The Peninsular 

Arch is an old uplift that runs 

north to south along Florida’s 

peninsula. Its axis approximates 

the Ocklawaha River Valley. The 

Ocala Platform (Ocala Uplift) 

is the name given to a younger 

sequence of gently folded rock 

and sediment formations about 

30 miles west of the Peninsular 

Arch. The Ocala Platform 

occupies an area about 230 miles 

long and 70 miles wide in the 

western Florida Peninsula (Lane 

and Hoenstine, 1991). In general, 

it passes along the western edge 

of the Ocklawaha Basin and influences 

western Alachua County, 

the middle and southern portions 

of Lake County, portions of southwestern 

Marion County, and Levy 

County. As the platform was 

formed, its sediment veneer was 

deposited more thinly and eroded 

more readily than elsewhere in 

Florida (Rosenau, 1977; Lane and 

Hoenstine, 1991). The combination 

of these factors resulted in 

the exposure or near-exposure 

of the rock formations that make 

up the Floridan aquifer and a 

general absence of the Hawthorn 

Formation west and south of 

Ocala, eastern Lake County, and 

western Alachua County. The 

Floridan aquifer in this part of 

the basin is relatively close to the 

land surface and generally under 

unconfined conditions. The 

stretching of rock strata as the 

uplift and arch developed caused 

faults and fractures to form in the 

limestones of the Floridan aquifer 

(Faulkner, 1970).


51 

lakes and streams. This aquifer is also very vulnerable to ground water 

contamination (see the Planning Unit maps in Chapter 3). 

Water discharges from the Floridan aquifer system as outflows 

to areas of lower head between aquifers, seepage and spring flow into 

streams and lakes, and evapotranspiration and/or pumpage. In the basin, 

the Ocklawaha River and most of the large connected lake chains and 

surrounding areas are generally places of discharge or limited recharge. 

Recharge to the Floridan aquifer occurs from rainfall that percolates 

downward, either directly from the surface when no confining layer 

is present or through overlying aquifer systems. The areas of highest 

ground water recharge are west of Interstate 75 and north of Gainesville 

(including the Fairfield Hills, Sumter Uplands, and Northern Highlands 

physiographic provinces) with at least 10 inches or more per year of 

recharge (Fernald and Purdum, 1998). The ridges and uplands on the east 

and south sides of the basin (Mt. Dora and Lake Wales) are also generally 

areas of significant ground water recharge (Bush, 1974). Sinkholes and 

fractures provide additional routes for water to move from the land surface 

to the aquifer. This is an important route in western Marion County and 

the Orange Creek Basin. Three major active sinkholes are present in the 

Orange Creek Basin: Alachua, Haile, and Orange Lake. Water entering 

Alachua Sink (Paynes Prairie) tends to flow in a northwesterly direction 

into the Suwannee Basin. Ground water entering the aquifer through 

the Orange Lake sinkhole flows primarily southwesterly toward Rainbow 

Springs (Lasi et al., 1996). 

A number of factors influence the vulnerability of the Floridan aquifer 

to contamination. These include location, proximity to the land surface, 

degree of confinement present, extensive karst features that allow rapid 

infiltration of surface water or direct transport of contaminants to the 

aquifer, and rate of recharge. Generally, the Floridan aquifer is most 

vulnerable in Marion County west of the Ocklawaha River valley, northern 

and western Alachua County, and southeastern Lake County (Clermont 

area). SJRWMD applies special basin criteria for stormwater management 

systems constructed in designated sensitive karst areas (SKAs) in western 

Alachua and Marion Counties to protect the Floridan aquifer system 

from inadequately treated stormwater. The Floridan aquifer system is 

unconfined and may occur within 20 feet of the land surface; the recharge 

rate is high (10 to 20 inches per year) in the SKAs. 

Major Water Quality Trends 

The most significant water quality trends in the Ocklawaha Basin 

are rising nitrate levels in springs, as well as low levels (and supersaturated 

levels) of dissolved oxygen (DO) and nutrient enrichment in surface waters. 

Springs and Nitrate Levels 

The median of 34 nitrate observations taken at five springs in the 

Ocklawaha Basin was 3.29 milligrams per liter (mg/L). This included 

data from Gourd Neck Spring, Bugg Spring, Blue Spring, Holiday Spring,


and Silver Springs. About half the data were collected from Gourd Neck 

Spring. Due to the significant contribution of water from Silver Springs 

to the Ocklawaha River, via the Silver River, the nitrate level in the 

Ocklawaha River is also a concern. 

Dissolved Oxygen 

All of the planning units in the basin, except the Florida Ridge 

planning unit, have DO concerns. There were insufficient data to assess 

the waters of the Florida Ridge planning unit. Table 2.4 shows the 

distribution of DO measurements in the other seven planning units of the 

basin, where data were available.

Nutrients and Eutrophication 

Elevated levels of nutrients, harmful algal blooms, and fish kills are 

all common symptoms of a eutrophic system. While some quantity of 

nutrients is necessary for plant growth, nutrient enrichment can result 

in excess growth of plants, including algae and macrophytes. Abundant 

plant growth, and associated consumption of DO through respiration and 

biomass decomposition, can lead to depressed DO levels and fish kills. 

Nitrate is a very important nutrient source in aquatic systems and is widely 

used by algae as a nutrient source. This form of nitrogen is often used to 

make proteins in a variety of organisms. Lack of nitrate in a system may 

inhibit algal growth, but undesirable blooms may occur if nitrate levels 

reach concentrations of 5 to 10 mg/L. Table 2.5 shows the distribution 

of nitrate measurements in the basin’s planning units, where data were 

available.

Blue-Green Algal Blooms 

Even in the absence of data substantiating a widespread nitrate problem 

in the Ocklawaha Basin, blue-green algae blooms have occurred in the 

basin since the 1950s. Blue-green algae have been a large component of 

the phytoplankton communities in Lake Apopka and most of the Upper 

Ocklawaha Chain of Lakes. Periodically, these lakes experienced bluegreen 

algae blooms (the presence of more than 500 algae cells per milliliter 

of water), and in many cases, concurrent fish kills caused by low DO 

levels (East Central Florida Regional Planning Council, August 1971; 

SJRWMD, 2001). Fish kills associated with blooms occurred in Lake Dora 

in 1997 and in Lakes Eustis and Harris in 1998 (Kent, June 2001, personal 

communication). Other fish kills, totaling about 17 tons of fi sh, occurred 

in Lake Dora in 1995. Historically, algae blooms were most common 

in Lakes Apopka, Beauclair, Carlton, Dora, Eustis, and Griffin. More 

recently, in the 1990s, blooms also occurred in Newnans Lake and Bevens 

Arm in the Orange Creek planning unit. 

Blue-green algae (see sidebar) often dominate the algal communities 

of waters receiving large loads of nutrients (eutrophic/hypereutrophic 

conditions). They can cause nuisance conditions and public health 

concerns such as odors, contaminated potable water supplies, reduced 

aesthetic value in recreational waters, low DO, and reduced clarity that 

shades out rooted vegetation. The loss of macrophytes due to shading 

shifts the trophic structure of a waterbody to one that is phytoplankton 

dominated. Dead algal cells settle to the lake bottom and contribute to 

the creation of an organic, flocculent sediment. This has been the case in 

the Upper Ocklawaha Chain of Lakes, Newnans Lake, and Lake Apopka, 

where extensive deposits of muck have been deposited on lake bottoms 

(Table 2.6). The shift in trophic structure and loss of hard bottom affects 

fisheries. Sportfi sh such as largemouth bass are greatly reduced in number

Blue-Green Algae 

Blue-green algae, or Cyanobacteria, 

are similar 

biologically to true bacteria, 

and were formerly classified 

as Cyanophyta. Like 

bacteria, they have neither 

a cell nucleus nor chloroplasts. 

Unlike most bacteria, 

however, they can 

photosynthesize like other 

algae and higher plants do. 

Like bacteria in the roots of 

leguminous plants, many 

can fix atmospheric nitrogen 

into a nitrogen form plants 

can use, an ability that other 

algae and higher plants lack. 

Blue-green algal growth is 

not limited by the amount of 

nitrogen in the water, while 

growth of other species of 

algae is limited. 

and fish populations shift to rough fi sh such as gizzard shad, which are 

more tolerant of the poor conditions. 

Algae may produce toxins that can harm wildlife and humans. Some 

Cyanobacteria produce hepatotoxins (liver toxins), neurotoxins (nervous 

system toxins), and dermotoxins (skin allergenics and irritants). In a 

1999 study by the SJRWMD (Williams et al., 2001), water samples were 

collected throughout the state from lakes and streams with the potential 

for algae blooms. Seventy-five out of a total of 167 waterbodies studied 

contained significant levels of toxin-producing blue-green algae. Eighty 

percent of the samples tested proved lethally toxic to mice. Of 69 water 

samples collected in waterbodies within the SJRWMD, 56 contained 

significant levels of toxin-producing blue-green algae. 

The most widespread and abundant species in water samples were 

Microcystis spp. and Cylindrospermopsis raciborskii (C. raciborskii), 

followed by Anabaena spp. All three organisms can produce hepatotoxic 

and neurotoxic compounds and are of the greatest concern in Florida. 

C. raciborskii is a particularly troublesome blue-green alga, because it is 

an exotic and invasive. Very little is known about the species, including 

the long-term effects of its toxin, cylindrospermopsin. This hepatotoxin 

largely affects the liver but may also affect the kidneys, spleen, thymus, 

and heart. The alga can be present in waterbodies and is sometimes not 

identified, because it does not create the surface scums and odors usually 

associated with blue-green blooms. C. raciborskii has been found in high 

concentrations in Lakes Beauclair, Carlton, Crescent, Dora, Eustis, Griffin, 

Harris, Lochloosa, Orange, Newnans, Wauberg, and Yale; Little Lake 

Harris; and Haines Creek. Exceptions are Haines Creek and Newnans 

Lake. Microcystis spp. has also been found in these waters. 

Lake Griffin has had the most severe algae blooms in the Upper 

Ocklawaha River watershed. Ninety-five percent of the phytoplankton 

population comprises C. raciborskii, with almost continuous domination 

by this species (Godwin, March 2001, personal communication). Blooms 

of C. raciborskii have occurred in Lake Griffi n at least since 1996 (Fulton, 

2002, personal communication). Concentrations of phosphorus in the lake 

have not shown the same increase. Researchers speculate that C. raciborskii 

is more efficient at turning nutrients into algal biomass than other bluegreen 

algae species. 

The relationship, if any, between the algal blooms and impacts to 

fish and wildlife is unknown. However, during periods of prolonged 

blooms, Lake Griffin has experienced failed year classes of major sport


55 

fish and increased mortality rates for alligators, soft-shelled turtles, and 

Florida gar (Williams et al., 2001). Since December 1997, more than 420 

large, dead alligators have been found in Lake Griffi n. However, alligator 

mortality has decreased since 2001 (Florida Fish and Wildlife Conservation 

Commission [FWC], 2003). Alligators in the lake have exhibited 

abnormal behavior consistent with a wild animal with severe neurological 

impairment. Examination has found lesions in the middle section of the 

brain. Several different possible causes are being examined, including 

toxins released by the blue-green alga C. raciborskii, pesticides, heavy 

metals, disease, nutrition, and the interaction of different factors. 

In response to the decline in alligator populations in Lake Griffi n, a 

partnership of 13 agencies and organizations was formed, called the Central 

Florida Lakes Wildlife Initiative, to investigate the problem and share 

research results. The initiative has identified research funding needs of over 

$900,000 (FWC, 2003). Agencies and organizations such as the FWC, 

Lake County Water Authority, SJRWMD, and Wildlife Foundation of 

Florida have contributed funding for related research needs. 

Watershed Management Activities and 

Processes 

Over the years, management plans and activities in the basin have 

been implemented to eliminate wastewater discharges; reduce discharges 

of polluted stormwater from urban and agricultural areas; and protect, 

preserve, and restore special areas. The following section describes 

historical, current, and ongoing activities and processes to address water 

quality problems. Table 2.7 contains a chronology of historical water 

quality events in the basin. 

Much of the progress in developing water quality restoration plans and 

implementing watershed and water quality improvements in the Ocklawaha 

Basin is attributable to coordinated local, state, and regional efforts. 

Many plans share common goals, and their implementation is based on 

various groups playing critical roles in planning, funding, managing, and 

executing projects. The Department continues to coordinate its efforts 

with these entities to obtain data, strengthen monitoring activities, and 

exchange information through periodic meetings. The local organizations 

and initiatives described in Table 2.8 provide leadership in waterbody 

restoration and preservation efforts. 

Major Programs and Projects 

A number of major restoration initiatives, if continued, will have major 

positive effects on the basin’s water quality. 

Regional Water Supply Plan and Priority Water Resource Caution

guide to the district in carrying out all water resource management 

responsibilities, including water supply, flood protection, water quality 

management, and protection of natural systems. The plan must include 

an assessment of water needs and sources for the next 20 years and identify 

specific geographic areas with water resource problems that have become 

critical or are anticipated to become critical within the next 20 years. The 

SJRWMD defines these critical areas as Priority Water Resource Caution 

Areas (PWRCAs). Five constraints are considered in establishing these 

PWRCAs: 

• Impacts to native vegetation, primarily wetlands; 

• Impacts to minimum flows and levels, primarily spring flows; 

• Impacts to ground water quality in terms of increased saltwater 

intrusion; 

• Impacts to existing legal users; and 

• Failure to identify a source of supply for future development. 

The Governing Board of the SJRWMD drafted a Regional Water 

Supply Plan in April 2000 and adopted the plan in June 2000. Based on 

economic, environmental, and technical analyses, a course of remedial or 

preventive action is specified in the plan for each current and anticipated 

future problem. Remedial or preventive measures may include, but are 

not limited to, water resource projects, water resources restoration projects 

pursuant to Section 403.0615, F.S., purchase of lands, conservation 

of water, reuse of reclaimed water, enforcement of Department or 

district rules, and actions taken by local government pursuant to a local 

government comprehensive plan, local ordinance, or zoning regulation. 

The southern half of the basin (Upper Ocklawaha Chain of Lakes, 

Lake Apopka, and portions of the Palatlakaha River watershed) is identified 

as part of a PWRCA. Predicted increases in water demand until the year 

2020 may have negative environmental effects. A conceptual Water Supply 

Plan for Work Group Area I: East Central Florida was completed by the 

SJRWMD in September 1999. Modeling projections infer the substantial 

lowering of both the Floridan and surficial aquifers under projected 

2020 water demands with potential for increased dewatering of wetlands 

and reduction of spring flows. The ridge regions of Lake County are 

predicted to be most heavily impacted. The middle St. Johns River and the 

Ocklawaha River at Lake Griffin are potential new alternative water supply 

sources. The Lake Apopka Basin is part of the Eastern I-4 Corridor Water 

Project. 

PWRCAs should not be confused with Water Resource Caution Areas 

(WRCAs) delineated pursuant to Section 62-40.416, F.A.C. The latter 

are areas where in implementing consumptive use permitting programs, 

a reasonable amount of reuse of reclaimed water is be required within 

designated WRCAs, unless objective evidence demonstrates that such reuse 

is not economically, environmentally, or technically feasible. The entire 

area of the SJRWMD has been designated a WRCA (Vergara, 2000).


Ocklawaha River Basin 

The Ocklawaha River Basin Study was authorized and adopted by 

Congress on July 26, 2000, although funds for the study have not been 

appropriated. The study provides for a review, by the Secretary of the 

Army, of the U.S. Army Corps of Engineers (USACOE) Four River 

Basins Report and other pertinent reports on comprehensive watershed 

planning for water conservation, water supply, flood control, environmental 

restoration and protection, and other water resource related concerns. The 

proposed study area includes the Palatlakaha River Basin, Lake Apopka 

Basin, and Upper Ocklawaha Basin north to the confluence with the Silver 

River. 

Lake Apopka 

Lake Apopka was named as a waterbody in need of restoration by the 

1987 state legislation creating the SWIM Program. An earlier legislative 

act, the 1985 Lake Apopka Restoration Act, required the restoration of 

Lake Apopka and created the Lake Apopka Restoration Council. Goals 

and management actions recommended by the council were incorporated 

into SWIM. From a premier bass-fishing lake in the 1950s, Lake Apopka 

has become a pea-green, poor water quality lake suffering from perpetual 

blue-green algae blooms. The lake’s deterioration was largely attributed to 

excess nutrients—mainly phosphorus—discharged from muck farms along 

the north shore. The first discharges of runoff from muck farms occurred 

in 1942, and the first algal bloom was recorded in 1947. Additional 

nutrient loads were contributed by discharges from domestic wastewater 

plants and citrus processing plants. Almost all direct discharges were 

removed in the 1970s and 1980s. 

Flocculent 

Sediments 

Soft, largely organic sediment, 

not very solid consistency, 

with large flocs 

and suspended solids. 

Lake Apopka SWIM Plan 

Key goals of the Lake Apopka SWIM plan are to restore water quality 

in the lake to Class III standards, to restore the functional capabilities of 

the lake’s natural system, to re-establish recreational and aesthetic values, 

and to implement a comprehensive basin management plan. Priority 

issues addressed in the development of a restoration plan were agricultural 

discharges, the lack of fi sh and wildlife, poor water quality and flocculent 

sediments, the degradation of downstream lakes, low recreational and 

aesthetic values, nonpoint source pollution, and future basin development. 

The primary focus of restoration goals and issues has been the 

reduction of internal and external nutrient loads to the lake. Three 

different strategies have been used to reach this goal: muck farm 

purchasing, littoral zone restoration, and gizzard shad harvesting. 

Muck farms located west of the Apopka–Beauclair Canal were 

purchased for the construction of large marsh flow-ways for fi ltering lake 

water to remove phosphorus. Operation of a two-square-kilometer pilotscale 

flow-way began in 1991. The wetland fi lter is capable of removing 

suspended solids and total phosphorus from Lake Apopka at or above 

target efficiencies of 35 percent and 30 percent, respectively. Phased 

construction of additional treatment cells began in 1997. Construction of 

Phase I treatment cells is complete.

Restoration and revegetation of the littoral zone of Lake Apopka will 

stabilize the shoreline and lake bottom, reduce sediment resuspension in the 

lake, and improve sport fish habitat. 

Gizzard shad are now the dominant fish species in the lake. They 

contribute to poor water quality by stirring bottom sediments, which 

releases phosphorus into the water column, and by eating the large 

zooplankton that feed on blue-green algae. From 1993 to 2000, 7.3 million 

pounds of shad were harvested from Lake Apopka, which removed 51,400 

pounds of phosphorus and 154,170 pounds of nitrogen (SJRWMD, 2001). 

The 1996 Lake Apopka Restoration Act set a criterion of 55 parts per 

billion (ppb) of phosphorus for the lake if the SJRWMD did not adopt an 

alternative phosphorus criterion by January 1997. The SJRWMD adopted 

by rule the 55 ppb criterion, as well as stormwater treatment requirements 

that would not allow postdevelopment phosphorus loads to exceed 

predevelopment loads. 

The Restoration Act also directed the water management district to 

buy remaining muck farms on the north shore of Lake Apopka, east of 

the Apopka–Beauclair Canal, rather than regulate the discharges from 

these farms. Funds for land acquisition were provided by the legislature, 

the water management district, and the U.S. Department of Agriculture 

Wetlands Reserve Program; the acquisition was completed in 1999. These 

lands will be restored to marsh over the next 10 years provided initial 

problems are resolved. 

As an early restoration activity, northshore farmlands were flooded, 

as farmers had done for decades during the summer fallow period. Land 

was allowed to remain flooded through fall until early winter, when water 

levels were lowered. The variable water depths that were created attracted 

numerous species of migratory birds. Birds began to die in early winter 

1998, with most mortality restricted to white pelicans and wood storks. 

The U.S. Fish and Wildlife Service began a criminal investigation of the 

bird deaths and made preliminary fi ndings of pesticide poisoning. The 

SJRWMD and the Natural Resources Conservation Service began an 

independent investigation and formed a Technical Advisory Group with 

representatives from 13 state, federal, local, and private organizations. 

Soil, water, and tissue samples have been collected for pesticide analysis 

in hopes of determining the cause of the bird deaths and identifying 

needed remediation activities. Several additional studies began in 

2001, with anticipated completion in 2003. Pesticide studies include a 

bioaccumulation study consisting of laboratory microcosms, in situ field 

mesocosms, and direct feeding of fi sh to birds. 

Lake Apopka Basin Planning Initiative 

Restoration activities will improve Lake Apopka, but the basin is experiencing 

the pressure of population growth and development as the Orlando 

metropolitan area continues to expand. The Lake Apopka Planning 

Initiative, started in 1999 by the East Central Florida Regional Planning 

Council at the request of the Friends of Lake Apopka, promotes regional 

cooperation among the basin’s six municipalities and two counties. Coordination 

is needed between local governments because a decision made by


one can undermine the efforts of a neighboring community to protect its 

shared natural resources. A steering committee created in 2000 comprises 

elected officials from each affected government. The East Central Florida 

Regional Planning Council, SJRWMD, and local government staff provide 

technical and administrative support. The initiative is not a set of projects 

or goals. Rather, it provides information in the form of needs and opportunities 

that identify where basin communities should direct their collective 

resources. Major initiatives include shoreline protection, greenways and 

trails, viewsheds, public access, stormwater management, and local planning 

and development coordination. 

Upper Ocklawaha Chain of Lakes 

The Upper Ocklawaha River was selected for restoration and approved 

as a SWIM priority waterbody in 1988. Prior to purchase under SWIM, 

muck farms were an integral component of the basin (Figure 2.2). 

Most muck farms were on the northeast shore of Lake Griffin in part of 

the Emeralda Marsh, north of Lake Harris, and along two channelized 

sections of the Ocklawaha River (Ocklawaha Prairie and Sunnyhill Farm). 

Nutrient-rich discharges from these agricultural operations, coupled 

with urbanization around the lakes, wastewater discharges, and lake level 

stabilization, resulted in deteriorated water quality and the loss of fish 

and wildlife habitat. An important source of additional loading to the 

chain of lakes is the low-quality discharge from Lake Apopka through 

the Apopka–Beauclair Canal. Discharges from Lake Apopka supply most 

of the nutrient load to Lakes Beauclair and Dora (Fulton, 1995). Other 

historical sources of nutrient loads are wastewater discharges from domestic 

plants and citrus processing plants. 

Upper Ocklawaha River Basin SWIM Plan 

The first SWIM plan was completed in 1989. The Upper Ocklawaha 

River SWIM Plan includes the area from the Apopka–Beauclair Lock 

and Dam to the confluence of the Silver and Ocklawaha Rivers near State 

Road 40. It includes Lakes Dora, Beauclair, Eustis, Griffin, Yale, Harris, 

and Weir; Little Lake Harris; and numerous springs. Five priority restoration 

issues were identified: excess levels of nutrients, potentially hazardous 

levels of metals and organic pollutants, the loss of fi sh and wildlife habitat, 

interagency coordination, and public involvement. 

Interim pollution load reduction goals (PLRGs) have been developed 

for phosphorus, with final PLRGs scheduled for completion at the end of 

2003. Interim PLRGs for the chain of lakes include limiting muck farm 

discharges and reducing the concentration of total phosphorus in the 

Apopka–Beauclair Canal to 0.05 parts per million (Fulton, 1995). 

Restoration projects in the basin focus on reducing phosphorus 

concentrations in lakes and restoring aquatic, wetland, and riverine habitat 

on former muck farms. Marsh flow-ways constructed in the former 

muck farms along Lake Griffi n are fi ltering the lake’s water to remove 

phosphorus. In addition, gizzard shad harvesting was begun in 2002 in 

Lake Griffin as a means of removing in-lake nutrients. More wetland 

habitat will be restored on former farmland by filling canals and ditches


67 

and breaching levees, which will hydrologically reconnect lakes and 

streams. Plans are under way to divert part of the flow now entering the 

C-231 canalized portions of the Ocklawaha River to the old river channel. 

The USACOE will provide partial funding for the project through its 

Section 1135 program. The modification of lake level water regulation 

schedules is proposed to return the system to a more natural seasonal 

fluctuation in lake levels. It is anticipated that the increased fluctuation 

will enhance the establishment of wetland habitat and secondarily aid water 

quality. The Corps must approve any modifications to the current water 

regulation schedule. The increased fluctuations increase the probability 

that adjacent properties will flood. 

Harris Chain of Lakes Restoration Council 

Created within the SJRWMD by the legislature in 2001 

(Chapter 2001-246, Laws of Florida), this council has been given the 

responsibility of reviewing and evaluating lake restoration activities 

and sport fish recovery strategies, evaluating whether additional studies 

are needed, and exploring all sources of funding to support restoration 

activities for the Harris Chain of Lakes. Primary focus of lake restoration 

is to improve fish and wildlife habitat and natural systems. The FWC 

is charged with conducting a demonstration restoration project to create 

better habitat for fish and wildlife. 

The council has nine members, including one representative of 

waterfront property owners, sportfishing industry, environmental 

engineer, attorney, physician, engineer, scientist, and two at-large members 

from Lake County. A largely scientific advisory group composed of 

representatives from SJRWMD, the Department, FWC, Department 

of Transportation, Lake County Water Authority, USACOE, and the 

University of Florida has been appointed to support the council. 

Lower Ocklawaha River/Rodman Reservoir 

Construction of the Cross-Florida Barge Canal dammed a 16-mile 

stretch of river and inundated about 9,000 acres of floodplain forest. 

After the project was deauthorized in 1991, the Canal Lands Advisory 

Committee was established to prepare a management plan for the newly 

created Cross-Florida Greenway. In 1992, Governor Lawton Chiles and 

the Florida Cabinet approved the management plan and recommended 

partial restoration of the reservoir to the Florida legislature. In 1993, 

the legislature adopted the management plan (Chapter 93-213, Laws of 

Florida), but did not appropriate money for restoration. In 2001, Governor 

Jeb Bush also endorsed the partial restoration of Ocklawaha River, but 

again the legislature did not provide funds. 

Some natural river hydrology and floodplain function will be restored 

to preconstruction conditions by breaching the dam and carrying out the 

limited removal and/or alteration of structures and topography. Partial 

restoration will involve a phased drawdown of the reservoir level, infi lling 

the Cross-Florida Barge Canal where it intersects the Ocklawaha River 

channel, closing and securing Buckman Lock, and removing 2,000 feet


of Kirkpatrick Dam along with other engineering and erosion control 

measures. 

Several issues must be addressed prior to restoration. Increased nitrate 

levels in Silver Springs and Silver River contribute undesirable additional 

nitrogen loads to the Ocklawaha River and ultimately the St. Johns River. 

High nitrogen loads in the St. Johns River have caused algal blooms and 

raised other water quality concerns. There is evidence that Rodman 

Reservoir may act as a treatment area and help remove some nutrients. A 

Special Use Authorization is needed from the U.S. Forest Service, because 

portions of Rodman Reservoir and Kirkpatrick Dam are on land that is 

part of the Ocala National Forest. Manatee protection must be provided 

in accordance with U.S. Fish and Wildlife Service requirements. The 

Department needs an environmental resource and consumptive use permit 

from the SJRWMD and additional permits from the USACOE. 

Silver Springs/Silver River 

Increasing concern about declines in water quality and the ecological 

health of Silver Springs and Silver River provided the impetus for the 

formation, in late October 1999, of a working group called Silver Springs 

Basin Working Group (formerly known as Silver Springs Forever: A 

Community Alliance). The Silver Springs Basin Working Group 

provides a stakeholder forum for identifying water-related problems and 

opportunities in the vast ground water area that contributes water to 

Silver Springs, thus linking and integrating diverse interests and activities, 

and promoting collaborative problem solving. Membership is open to 

public and private interests such as government, business, agriculture, and 

environmental groups. 

The Silver Springs Basin Working Group’s management structure is 

organized as the full working group of all members, a steering committee, 

and issue-specific committees. Individual committees are organized as 

Research, Land Use and Resource Management, Public Awareness and 

Education, Funding, and Rainbow Springs. A separate citizen group, the 

Friends of Silver River, was formed as an advocacy group for Silver River. 


The governing board of the SJRWMD created the Orange Creek 

Basin Advisory Council in 1993 to address basin issues and water resource 

management needs. A scientific advisory committee advises the council 

on technical issues. Membership on the council includes representatives of 

local government in Alachua and Marion Counties, the water management 

district, FWC, the Department, Gainesville Regional Utilities, fishing 

interests, local businesses, and environmental groups. 

Orange Creek Basin Surface Water Management Plan 

The Orange Creek Basin Surface Water Management Plan was completed 

in 1996. The initial focus of projects has been the investigation of 

a sinkhole complex in Orange Lake that affects lake water levels. During 

periods of drought, the lake naturally drains to the sinkhole and ground 

water. The sinkhole has been a contentious issue for the past 50 years,


69 

particularly for fish camp owners around Orange Lake who depend on 

fairly stable lake levels to support their businesses. Numerous unsuccessful 

attempts have been made to dam the sinkhole, starting in 1957 with the 

construction of a berm around it. In 2000, the Orange Creek Basin Advisory 

Council voted seven to three against sinkhole intervention in Orange 

Lake. Other issues addressed in the Orange Creek Basin Surface Water 

Management Plan are the development of a restoration plan that addresses 

deteriorating water quality in Newnans Lake, the effects of stormwater on 

urban lakes and streams, and the potential need for management of Orange 

Lake’s wetlands.

The Orange Creek Basin Partnership was created in 1997 between 

Gainesville Regional Utilities, City of Gainesville Department of Public 

Works, Alachua County Environmental Protection Department, Alachua 

County Public Works, the Department, and SJRWMD. The partnership 

focuses on enhancing the coordination of activities and sharing expertise 

toward addressing water quality and stormwater issues. Activities have 

focused on water quality and habitat monitoring of lakes, stormwater 

impacts on urban streams, and the assessment of potential causes for vegetative 

changes in Paynes Prairie. 

Orange Creek Restoration Area Land Management Plan 

A draft Orange Creek Restoration Area Land Management Plan, 

completed in April 1999, proposes guidelines for implementing a fi ve-year 

plan for land management activities in the Orange Creek restoration area, 

the portion of Orange Lake east of U.S. Highway 301. This area was part 

of the wetland zone of Orange Lake before it was diked and drained in the 

1930s to create Shands Muck Farm (now known as Orange Lake Muck 

Farm). Orange Creek Canal, created by canalizing 1.2 miles of Orange 

Creek, flows through the property before entering the Ocklawaha River at 

Rodman Reservoir. The goals of the four-year restoration project are to 

restore wetland function through hydrologic reconnection to Orange Lake 

and to reduce nutrient loading to Orange Creek and Rodman Reservoir. 

The 3,415-acre farm property was acquired in April 1998. Funding was 

provided through Preservation 2000 and the Natural Resource Conservation 

Service’s Wetland Reserve Program. 

Agricultural Best Management Practices 

The Florida Watershed Restoration Act authorizes the Florida 

Department of Agriculture and Consumer Services (DACS) to develop 

interim measures and agricultural best management practices (BMPs). 

Additional authority for agricultural BMPs is provided in legislation on 

nitrates and ground water (Section 576.045, F.S.), the Lake Okeechobee 

Protection Program (Section 373.4595, F.S.), Agricultural Water 

Conservation (Section 570.085, F.S.), and Florida Right to Farm Act 

Amendments (Section 823.14, F.S.). While BMPs are often adopted by 

rule, they are voluntary if not covered by regulatory programs. If they 

are adopted by rule and the Department verifies their effectiveness, then


implementation provides a presumption of compliance with water quality 

standards. 

Over the last several years, DACS has worked with agriculturists, soil 

and water conservation entities, the University of Florida’s Institute of Food 

and Agricultural Sciences, and other major interests to improve product 

marketability and operational efficiency by implementing agricultural 

BMPs, while at the same time promoting water quality and water 

conservation objectives. In addition, programs have been established and 

are being developed to create a network of state, local, federal, and private 

sources of funds for developing and implementing BMPs. 

To encourage growers to use BMPs, BMP manuals have been published 

for a number of agricultural industries. Many of these manuals can be 

downloaded at http://www.dep.state.fl.us/water. The use of a BMP manual 

alone, however, does not presume compliance with the Department’s water 

quality standards. BMP manuals applicable to the Ocklawaha Basin 

include the following: 

• Guide for Producing Container-Grown Plants. This manual, 

published in 1995 by the Southern Nurserymen’s Association, 

includes irrigation and fertilization BMPs for the container cultivation 

of nursery plants. It was produced through a cooperative effort 

between the University of Florida, Auburn University, Tennessee 

Tech University, and Virginia Tech. As the manual is not Floridaspecific, 

an effort is currently under way to use the document in 

developing a Florida-specific manual. 

• BMPs for Blended Fertilizer Plants in Florida. The manual for 

blended fertilizer industrial operations, published in October 1997, 

was cooperatively produced by the Florida Fertilizer and Agrichemical 

Association, DACS, and the Department. 

• BMPs for Agrichemical Handling and Farm Equipment 

Maintenance. Recently revised and reprinted, this manual gives 

producers guidance on hazardous materials, proper pesticide handling, 

and the proper disposal of waste products. It was cooperatively 

produced in 1998 by DACS, the Department, and several 

industry associations. 

• Water Quality BMPs for Cow/Calf Operations. Many cattle 

operators statewide have been trained in using this manual and 

applying BMPs. The Florida Cattlemen’s Association and several 

state, federal, and local agencies developed the manual, which was 

published in 1999. Copies were printed and distributed in 2000 

using EPA Section 391 grant funds. 

• Florida Green Industries BMPs for Protection of Water 

Resources in Florida. This manual provides BMPs for professional 

turfgrass and landscape managers. Published in 2002, it was developed 

through a cooperative effort by Florida Green Industries (an


71 

industry association); the Department; DACS; the Florida Department 

of Community Affairs; and the St. Johns, South Florida, and 

Southwest Florida Water Management Districts. 

• Rule-Based Initiatives. Under Section 576, F.S., in 2002 DACS 

adopted BMPs by rule for the Lake Wales Citrus Ridge region, and 

in 1996 adopted BMPs by rule for leatherleaf fern production areas in 

and around Volusia County. 

• Ongoing BMP Initiatives. DACS’s Office of Agricultural Water 

Policy expects to produce in the next year draft manuals on management 

of row crops (generally applicable statewide), equine or horse 

farms (applicable to both small landowner operations and concentrated 

facilities), and ornamental nurseries.

Chapter 3: Surface Water Quality 

Assessment 

Scope of the Assessment 

This chapter presents the results of an updated assessment of surface 

water quality in the Ocklawaha Basin. The primary purpose of the 

assessment is to determine if waterbodies or waterbody segments are to be 

placed on the Verified List of impaired waterbodies. The listing will be 

in accordance with evaluation thresholds and data sufficiency and data 

quality requirements in the Identification of Impaired Surface Waters Rule 

(IWR) (Rule 62-303, F.A.C.). The results of the assessment will be used 

to identify waters in the basin for which Total Maximum Daily Loads 

(TMDLs) will be developed. 

The chapter describes the planning units in the basin used as a 

basis for the assessment. A section on each planning unit contains a 

general description and summary of key water quality indicators (such 

as nutrients, chlorophyll a, dissolved oxygen [DO], and microbiological 

parameters). Permitted discharges, land uses, ecological status, and water 

quality improvement plans and projects are summarized for each planning 

unit. The discussion notes where applicable surface water quality criteria 

have been exceeded and summarizes the report’s findings in maps, noting 

potentially impaired waterbodies in each planning unit. The chapter also 

contains background information on sources of data and on designated 

use attainment, and explains the state’s integrated water quality assessment 

process. 

While potentially impaired waters and their causative pollutants 

are identified, it is not within the scope of this report to identify 

discrete sources of potential impairments. Information on the sources 

of impairment will be developed in subsequent phases of the watershed 

management cycle, including TMDL development and implementation. 

Appendix A contains a discussion of the legislative and regulatory 

background for TMDL development and implementation. Appendix C 

provides additional information on reasonable assurance. Appendix D 

provides the methodology used to develop the Planning and Verified Lists. 

(The complete text of the IWR is available at http://www.dep.state.fl.us/ 

water/tmdl/docs/AmendedIWR.pdf.) Appendix E contains the integrated 

water quality assessment summary (Table E.1), the water quality 

monitoring stations used in the assessment (Table E.2), and data on 

water quality trends (Table E.3). Appendix F lists permitted wastewater 

treatment facilities in the basin that discharge to surface water and ground 

water, Appendix G lists Level 1 land use by planning unit, and 

Appendix H lists comments received during the Verified List public 

comment period.


Update on Strategic Monitoring and Data- 

Gathering Activities During Phase 2 

Chemical and biological data and fish consumption advisories were 

used in Phase 1 of the watershed management cycle to assess the water 

quality status of the Ocklawaha Basin and to develop a Planning List of 

potential impairments. In Phase 2 of the watershed management cycle, 

data from strategic monitoring and further data-gathering activities 

were incorporated into the assessment of the Ocklawaha Basin to verify 

impairments and to develop the Verified List. A detailed description of the 

methodology used to develop the Planning and Verified Lists is available in 

Appendix D. 

During Phase 2 of the watershed management cycle, strategic 

monitoring and data-gathering activities focused first on waters on 

the 1998 303(d) list, followed by waters that were placed on the 

Planning List through the IWR assessment alone. The majority of the 

strategic monitoring work was conducted by the Florida Department 

of Environmental Protection’s (Department) Central District staff and 

included both chemical and biological monitoring and data upload 

to STOrage and RETrieval (STORET). Data-gathering activities 

included working with environmental monitoring staff in the St. Johns 

Regional Water Management District (SJRWMD) and local and county 

governments to obtain applicable monitoring data from their routine 

monitoring programs and special water quality projects in the basin. 

Appendix E of this report provides a list of the water quality monitoring 

stations used in the assessment of the Ocklawaha Basin and the data 

providers who contributed data during Phase 2. 

There were 67 waterbody segments on the Planning List and 1998 

303(d) list that needed further data to allow verification of impairment. 

Parameters involved included silver, cadmium, iron, lead, and selenium. 

Also included were biology (based on bioassessments), biological oxygen 

demand (BOD), DO, fecal and total coliforms, unionized ammonia, 

nutrients and their indicators (nitrogen, phosphorus, chlorophyll a), 

turbidity, and total suspended solids (TSS). Forty waterbody segments 

were verified impaired for at least one parameter in the Ocklawaha Basin as 

the result of strategic monitoring and data-gathering activities in Phase 2. 

Further data from the planning and verified periods have become 

available for assessment of the basin since the October 2002 update of 

the 303(d) list in Phase 2. Table I.1 in Appendix I provides the updated 

impairment status of the Ocklawaha Basin through January 2003. It 

should be noted that changes in impairment status expressed in 

Table I.1 were not included in the Amended Order signed by the 

Department’s Secretary on March 11, 2003.


75 

Sources of Data 

The assessment of water quality in the Ocklawaha Basin includes 

an analysis of quantitative data from various sources, many of which are 

readily available to the public. Sources include the U.S. Environmental 

Protection Agency’s (EPA) Legacy and “new” STORET databases, the 

U.S. Geological Survey (USGS), the Florida Department of Health, the 

Department, water management districts, local governments, and volunteer 

monitoring groups. 

Table 3.1 summarizes the individual data providers who contributed 

to the IWR 2002 Database for the Ocklawaha Basin for the period of 

record used in this assessment. Table 3.1 only reflects data provided to the 

Department through October 2002. Figure 3.1 shows the contribution of 

each provider by year. Data providers contributing the largest amount of 

data for this assessment are Florida LakeWatch (41 percent), SJRWMD 

(35 percent), and Lake County (9 percent). 

The Department created the IWR 2002 Database to evaluate data 

in accordance with the methodology prescribed in the Identification of 

IWR (Rule 62-303, F.A.C.). For the Verified List assessment, the data 

evaluation period of record is 7 years, and for the Planning List, 10 years. 

Table E.1 in Appendix E lists the STORET stations in each planning 

unit from which data were extracted for this assessment, the agency 

collecting the data, and the periods of record. Table D.2 in Appendix D 

shows the planning and verification periods for each group in the first basin 

rotation cycle. The planning period for the Ocklawaha Group 1 Basin 

is January 1, 1989, through December 31, 1998. The verification period 

is January 1, 1995, through June 30, 2002. To support listing decisions, 

the evaluation of water quality in this basin also includes qualitative 

information drawn from data in technical reports and documents that are 

not yet included in the database. Some of these sources include historical 

water quality or ecological information that was not uploaded to the 

database because of its qualitative treatment of issues.

Attainment of Designated Use 

While the designated uses of a given water are established using the 

surface water quality classification system described in Chapter 2, it is 

important to note that the EPA uses slightly different terminology in 

its description of designated uses. Because the Department is required 

to provide use attainment status for both the state’s 305(b) report and 

the state’s 303(d) list of impaired waters, the Department uses EPA 

terminology when assessing waters for use attainment. The water quality 

evaluations and decision processes for listing impaired waters that are 

defined in Florida’s IWR are based on the following designated use 

attainment categories: 

Aquatic Life Use Support-Based Attainment 

Primary Contact and Recreation Attainment 

Fish and Shellfish Consumption Attainment 

Drinking Water Use Attainment 

Protection of Human Health 

Table 3.2 summarizes the designated uses assigned to Florida’s various 

surface water classifications.

Integrated Report Categories and Assessment 

Overview 

The EPA has requested that the states merge their reporting 

requirements under the Clean Water Act for Section 305(b) surface 

water quality reports and Section 303(d) lists of impaired waters into an 

Integrated Water Quality Monitoring and Assessment Report. This Assessment 

Report integrates the 303(d) list and the 305(b) report for this basin. 

Following the EPA’s guidance, the Department delineated waters 

in each of the state’s river basins, assessed them for impairment based 

on individual parameters, and then placed them into one of five major 

assessment categories and subcategories. These categories describe the 

status of a water based on water quality, sufficiency of data, and the need 

for TMDL development (Table 3.3). This Assessment Report contains a 

comprehensive evaluation of waterbodies that fall into Integrated Report 

Categories 1 through 5 in the table.

information and data to determine if designated uses 

are attained. 

This indicates a water or segment is potentially impaired 

for one or more designated uses. These waters will be 

prioritized for future monitoring to verify use attainment or 

impaired status. 

This indicates that a waterbody or segment exceeds Verified 

List evaluation criteria and may be listed as impaired 

at the end of Phase 2 of the watershed management cycle. 

However, the data have not yet been fully evaluated and 

the waters have not been formally verified as impaired. 

Further monitoring and analysis may be necessary. 

This category is applicable only to the Status Report. 

Waters that pass the Verified List criteria are placed in 

Category 5. 

After a TMDL for the impaired water or segment is 

approved by EPA, it will be included in a Basin Management 

Action Plan to reduce pollutant loading toward attainment 

of designated use(s). 

This category includes waterbodies or segments that are 

impaired because of naturally occurring conditions or 

pollution. The impairment is not caused by a specific pollutant. 

(See sidebar on next page for a discussion of the 

difference between pollution and pollutants.) 

Pollutant control mechanisms designed to attain applicable 

water quality standards within a reasonable time frame are 

either proposed or in place 

Waterbodies or segments in this category are impaired for 

one or more designated uses by a pollutant or pollutants. 

Waters in this category are included on the basin-specific 

Verified List adopted by the Department’s Secretary as 

Florida’s impaired waters list and submitted to the EPA as 

Florida’s 303(d) list of impaired waters at the end of 

Phase 2.


79 

Waterbodies that are verified impaired due to specified pollutants, and 

therefore require a TMDL, are listed under Category 5 in the Integrated 

Assessment Report; waterbodies with water quality impairments due to 

other causes, or unknown causes, are listed under Category 4b. Although 

TMDLs are not established for Category 4b waterbodies, these waterbodies 

still may be addressed through a watershed management program (for 

example, the Kissimmee River restoration). 

Currently only a few waters statewide fall into Category 1 (attaining 

all designated uses), because few have sufficient chemical, biological, and 

fish consumption advisory data to assess them for all designated uses. In 

particular, fish tissues in many waters statewide have not been tested for 

mercury. None of the 441 waterbody segments in the Ocklawaha Basin 

falls into Category 1. 

More waters statewide fall into Category 2 (attaining some designated 

uses but with insufficient data to assess all uses), because monitoring 

programs have provided at least some data from which to assess attainment 

of some uses. A total of 57 waterbody segments in the Ocklawaha Basin 

fall into Category 2. 

However, most waters in the Ocklawaha Basin and the state as a whole 

fall into Category 3 (having insufficient data). In the Ocklawaha Basin, 

the breakdown of waterbody segments in Category 3 is as follows: 

• Category 3a—196 segments for which no data are available to determine 

their water quality status; 

• Category 3b—74 segments with some data, but not sufficient data 

for making any determinations; 

• Category 3c—44 segments that are potentially impaired based on 

the Planning List criteria or may be impaired based on the Verified 

List criteria, but require further evaluation for verification. 

Several potentially impaired (Category 3c) waterbody segments in 

the Ocklawaha Basin either fail to meet water quality standards for DO, 

or show signs of biological stress or nutrient impairment. Waters that 

meet the threshold of verified impairment for DO, biology (based on 

bioassessment) or nutrients (chlorophyll a or Trophic State Index [TSI]) 

must also have the pollutants that underlie these impairments identified 

before the water is placed on the Verified List. In cases where the 

underlying pollutant cannot be identified, and the impairment has been 

concluded to be not due to natural background conditions, the water is 

retained on the Planning List until further information can be obtained to 

determine the causative pollutant. For nutrient impairments, the causative 

pollutant is the limiting nutrient (nitrogen or phosphorus). 

Currently, no waters in the Ocklawaha Basin are designated as being in 

Category 4. This category includes those waters that are impaired but do 

not require a TMDL for one of three reasons: 

Understanding the 

Terms “Pollutant” 

and “Pollution” 

For purposes of the TMDL 

Program, pollutants are 

chemical and biological 

constituents, introduced 

by humans into a waterbody, 

that may result in 

pollution (water quality 

impairment). There are 

other causes of pollution, 

such as physical alteration 

of a waterbody (for example, 

canals, dams, and 

ditches). However, TMDLs 

are established only for 

impairments caused by 

pollutants (a TMDL quantifies 

how much of a given 

pollutant a waterbody can 

receive and still meet its 

designated uses). 

• Category 4a—segments for which a TMDL has already been 

developed,


• Category 4b—segments for which the impairment is not attributable 

to a pollutant or pollutants but is due to other alterations to the 

waterbody, and 

• Category 4c—segments for which there is reasonable assurance that 

the designated use of an impaired waterbody will be attained by an 

existing or proposed pollutant control measure. 

Forty waters in the Ocklawaha Basin are in Category 5. These 

impaired waters have been included on the Verified List adopted by the 

Department’s Secretary and will require TMDLs. Chapter 5 of this report 

discusses in detail the waters in this category. 

Planning Units 

The Ocklawaha Basin encompasses approximately 2,800 square miles 

and a complex hydrologic system. To provide a more detailed geographic 

basis for identifying and assessing water quality improvement activities, the 

basin was subdivided into smaller areas called planning units. A planning 

unit is either an individual large tributary basin or a group of smaller 

adjacent tributary basins with similar characteristics. Planning units 

help organize information and management strategies around prominent 

watershed characteristics. 

Water quality assessments were conducted for waterbody segments 

within planning units. Each of these smaller, hydrologically based drainage 

areas within a planning unit is assigned a unique waterbody identification 

number (WBID). Waterbody segments are assessment units (or geographic 

information system [GIS] polygons) that the Department used to defi ne 

waterbodies when it biennially inventoried and reported on water quality 

to the EPA under Section 305(b) of the federal Clean Water Act. These 

WBIDs are the assessment units identified in the Department’s lists of 

impaired waters submitted to the EPA in reports under Section 303(d) of 

the Clean Water Act. 

The Ocklawaha Basin contains eight planning units: Lake Apopka, 

Palatlakaha River, Lake Griffi n, Lake Harris, Marshall Swamp, Florida 

Ridge, Rodman Reservoir, and Orange Creek. Table 3.4 describes these 

planning units, and Figure 3.2 shows their locations and boundaries. The 

remainder of this chapter provides a discussion of each planning unit, 

information on land uses and potential point sources of pollution, water 

quality assessments for individual waterbody segments, and summaries of 

ecological issues and watershed quality improvement plans and projects. 

Appendix E of this report provides a list of the water quality 

monitoring stations used in the assessment of the Ocklawaha Basin and 

water quality trend data, by planning unit. Appendix F includes summary 

information, by planning unit, for permitted wastewater treatment 

facilities, Superfund sites, and permitted landfill facilities in the basin. 

Appendix G lists Level 1 land uses, by planning unit.

Description 

The 183-square-mile lake apopka planning unit encompasses Lake Apopka, other lakes 

in the southeastern part of the Ocklawaha Basin, several muck farms purchased by the 

SJRWMD for restoration, other areas that drain into Lake Apopka, and several springs. It 

also includes portions of the Apopka–Beauclair Canal, the only outlet for Lake Apopka. 

The Palatlakaha River originates in Polk County in the Green Swamp and discharges into 

Lake Harris, draining about 223 square miles. Big Creek and Little Creek are streams that 

drain into Lake Louisa, part of the Clermont Chain of Lakes, which are all connected by the 

Palatlakaha River. The planning unit also contains several additional lakes and wetlands. 

The Lake Griffin planning unit includes Lake Griffin and Lake Yale and the canal system 

that connects them. It also includes some tributaries to Lake Griffin, Emeralda Marsh, several 

smaller lakes, and a portion of Haines Creek. The planning unit is about 232 square 

miles. 

The Lake Harris planning unit includes Lake Harris, Little Lake Harris, Lake Carlton, Lake 

Ola, Lake Beauclair, Lake Dora, Lake Eustis, and the canal systems that connect them. It 

also includes the Little Everglades Tributary, which connects the Little Everglades Swamp 

and Little Lake Harris. The unit also includes other small lakes and canals within its boundaries, 

comprising about 240 square miles. 

The Marshall Swamp planning unit, which drains about 164 square miles, includes Lake 

Weir, Little Lake Weir, Smith Lake, and several other lakes. It also includes Marshall 

Swamp, Silver Springs, Silver River, and portions of the Ocklawaha River. 

The Florida Ridge planning unit includes Ledwith Lake, Mud Pond, Fairfield Sink, and Priest 

Prairie Drain. None of these waters has direct surface water drainage into the Ocklawaha, 

but rather, all drain to ground water. The planning unit is about 691 square miles. 

The Rodman Reservoir planning unit includes many other lakes besides Rodman Reservoir 

(e.g., Halfmoon Lake, Lake Charles, Redwater Lake, North Lake, Lake Bryant, Mill Dam 

Lake, and Lake Jumper). It also includes Eaton Creek, Daisy Creek, Mill Creek, Bruntbridge 

Brook, Deep Creek, Sweetwater Creek, and portions of the Ocklawaha River in its drainage 

basin, which is approximately 472 square miles. 

Orange Creek The Orange Creek planning unit contains many creeks and lakes in approximately 602 

square miles. The larger creeks include Tumblin’ Creek, Sweetwater Branch, Hogtown 

Creek, Possum Creek, Little Hatchet Creek, Lochloosa Creek, Lake Forest Creek, Prairie 

Creek, Little Orange Creek, Cabbage Creek, Orange Creek, and many others. The lakes 

include Bevens Arm, Lake Alice, Newnans Lake, Orange Lake, Little Orange Lake, Lochloosa 

Lake, and many others. This unit also includes sinks, such as Alachua Sink and 

Haile Sink, as well as Paynes Prairie and several springs. Orange Creek receives drainage 

from the basin and discharges directly to the Ocklawaha River through Rodman Reservoir. 

Sweetwater Branch and Hogtown Creek discharge to ground water through sinks. 

Assessment by Planning Unit 

The following is an assessment of water quality and impairment status 

for each planning unit in the Ocklawaha Basin. It provides a general 

description of each planning unit, a discussion of where applicable surface 

water quality criteria have been exceeded, and the key indicators associated 

with impairments. It includes discussion of permitted discharges, Level I 

and Level II land uses, and the overall ecological status of each planning 

unit. Also discussed are water quality improvement plans and projects that 

are expected to provide reasonable assurance that water quality standards 

will be met in the future.

• Lake Apopka Planning Unit 

General Description 

The 183-square-mile Lake Apopka planning unit encompasses Lake 

Apopka, other lakes in the southeastern part of the Ocklawaha Basin, 

several muck farms purchased by the SJRWMD for restoration, other 

areas that drain into Lake Apopka, and several springs. It also includes the 

Apopka–Beauclair Canal, the only outlet for Lake Apopka, downstream 

to the Apopka-Beauclair Lock and Dam. Figure 3.3 shows the individual 

waterbody segments assessed in the Lake Apopka planning unit. 

Water Quality Summary 

Table 3.5 provides an integrated water quality assessment for each 

waterbody segment in the Lake Apopka planning unit. Maps showing 

integration by parameter group for the Ocklawaha Basin as a whole are in 

Appendix J. Figure 3.3, a composite map of the planning unit, shows 

waters on the 1998 303(d) list, Planning List, and Verified List, and 

potential pollution sources.

concentrations, low DO levels, high unionized ammonia and turbidity 

levels, and poor biological community structure. Most of these problems 

are either directly or indirectly related to excess nutrients. As habitats are 

altered by the effects of nutrient enrichment, the biological components of 

the system respond, with a shift toward pollution-tolerant species and low 

species diversity. The waterbodies in the planning unit that have at least 

some of the indicators of nutrient enrichment include Lake Apopka, Gourd 

Neck Spring, Lake Avalon, Johns Lake, and Black Lake Outlet. 

Nutrient and DO problems in Gourd Neck Spring are consistent 

with the water quality condition of most springs in the state. Low DO 

in springs, however, is at least partially attributable to the influence of 

ground water, which is typically low in DO in the absence of any known 

impairment. 

Nutrient enrichment of Lake Apopka and other lakes connected to 

it has a long history. In the late 1800s, Lake Apopka was drawn down 

through the construction of the Apopka–Beauclair Canal to provide rich 

farmland, particularly on the shallow north shore of the lake (SJRWMD,

Parameters in this column meet the verification thresholds in Table 2 of the IWR. Those shown in italics have a status of 

Category 4a, 4b, or 4c. Those unitalicized have a status of Category 5.

The EPA’s 305(b)/303(d) Integrated Report categories are as follows: 

1—Attains all designated uses; 

2—Attains some designated uses; 

3a—No data and information are available to determine if any designated use is attained; 

3b—Some data and information are available, but they are insufficient for determining if any designated use is 

attained; 

3c—Meets Planning List criteria and is potentially impaired for one or more designated uses; 

4a—Impaired for one or more designated uses and the TMDL is complete; 

4b—Impaired for one or more designated uses but no TMDL is required because the impairment is not caused by a 

pollutant; 

4c—Impaired for one or more designated uses, but no TMDL is required because a proposed pollution control measure 

provides reasonable assurance that the water will attain standards in the future; and 

5—Water quality standards are not attained and a TMDL is required. 

These categories are typically applied to individual parameters assessed within waters. In this table, they represent an 

overall assessment status for the water as a whole, arrived at by setting precedence among the integrated reporting categories 

of the parameters assessed. For instance, if the water attained some designated uses as indicated by some parameters 

meeting standards (integrated reporting Category 2), but water quality standards were not met for other parameters, 

(integrated reporting Category 5), the overall status of the water was reported as Category 5 (water quality standards are 

not attained and at least one TMDL is required within the waterbody segment).

1998). Muck farms, as they became known, operated there from the early 

1900s to the mid-1990s. These farms were actually at a lower elevation 

than the lake itself. During periods of high rainfall, excess water from the 

farms was back-pumped into the lake, carrying with it significant amounts 

of farm-related pollutants, including sediment, nutrients from the muck 

itself, and pesticides. 

The SJRWMD has placed into public ownership most of these 

muck lands and has eliminated back-pumping, but the legacy of years of 

sedimentation and nutrient enrichment continues to cause algal blooms 

and other nutrient-related water quality problems. The Lake Apopka 

Restoration Act and the SWIM Act have identified Lake Apopka as a 

priority for restoration. In addition, the Department is developing a 

TMDL for phosphorus for the lake, with a proposed load of 15.9 metric 

tons per year. 

Other water quality concerns in the planning unit are elevated copper 

and lead levels in Lake Avalon and Johns Lake. These two lakes are 

located in the southern part of the planning unit, south of Lake Apopka, 

in an area that is not heavily urbanized. In the absence of other known 

sources of heavy metals in this area, it is possible that the Florida Turnpike, 

which traverses the watersheds of these two lakes, is contributing metals 

through roadway runoff of fuel constituents. Another source of metals 

contamination could be long-term use of these waters for boating. 

Two waterbody segments in the planning unit met standards for 

biology (based on macroinvertebrate-based bioassessments)—Crown Point 

Slough, located southeast of Lake Apopka, and what is known as Lake 

Apopka Outlet, which is the area surrounding Lake Apopka. Both of these 

areas are either in the process of being restored to a natural state or are out 

of the direct influence of historical muck farming in the planning unit. 

Permitted Discharges and Land Uses 

Permitted Discharges. The largest surface water discharger in 

the Lake Apopka planning unit is the City of Winter Garden Domestic 

Wastewater Treatment Facility, which is permitted to discharge 2 million 

gallons per day (mgd) of advanced secondary treated effluent to surface 

waters. The facility is required to monitor the flow, nitrogen, phosphorus, 

DO, and BOD content of its effluent before discharge to Lake Apopka 

through percolation ponds with underdrains. Some discharge also goes 

to the Forrest Lakes Golf Club course for reuse. Three other facilities 

within the planning unit have National Pollutant Discharge Elimination 

System (NPDES) permits—Duda and Sons/Redi Foods for screening 

and sprayfield discharge, Ewell/Winter Garden Concrete Batch Plant, and 

Cumberland Farms Petroleum Cleanup Air Stripping Facility. Several 

other discharges in the planning unit go to percolation ponds or sprayfields 

or are redirected for reuse. 

Appendix F lists the domestic and industrial surface water discharge 

facilities in the planning unit with their design flows, as well as any landfi lls 

or solid waste facilities. See Noteworthy for a definition of point sources 

and general discussions of environmental remediation and delineated 

ground water contamination areas.


Land Use Considerations. Appendix G lists land uses in the 

basin, by planning unit. Water covers almost one-third of the planning 

unit. The most significant land uses other than “water” are row and field 

crops, with citrus close behind. Agricultural land uses such as these can 

be associated with nonpoint source discharges of pollutants and eroded 

sediments (see Noteworthy for a definition of nonpoint sources). As 

discussed in Chapter 2, the SJRWMD has purchased almost all of the 

muck farms that were located on the north shore of Lake Apopka. This 

will significantly change land use from muck farming (agricultural) to 

wetlands, and is expected to improve future water quality in the planning 

unit. 

Ecological Summary 

An abundant number of different bird species inhabit the planning 

unit. Many are attracted to the marsh flow-way and other wetland 

restoration areas. As many as 71 species of birds were observed using the 

demonstration marsh flow-way from 1990 to 1994 (Stenberg et al., 1998). 

A large wading bird rookery (1,000 to 3,000 birds) observed on the lake’s 

southwest side in 1999, near Pine Island and Gourd Neck Spring, has 

documented use since the 1970s. A second rookery, in the lake’s southeast 

corner, largely comprises white ibis (Eudocimus albus). At least eight active 

eagle nests were observed in 1999 in the southern half of the planning unit. 

Cultural eutrophication of Lake Apopka, due to nutrient enrichment, 

has contributed to a decline in water quality and alteration of plant and 

animal communities in the lake since the 1940s (SJRWMD, 2000). About 

84 percent of the nutrient load to the lake historically came from muck 

farms (SJRWMD, 2001) located on the north shore of the lake. Many 

of the muck farms have now been purchased and restored, but the lake 

has a history of perpetual algal blooms, with the first recorded in 1947. 

Since 1947, there has been a shift from primary production dominated 

by macrophytes to primary production by phytoplankton (Schelske, 

1997). Emergent vegetation is largely composed of cattails. Before the 

construction of muck farms in the 1940s, the lake was surrounded by 

sawgrass marshes, which are generally viewed as better adapted to low 

nutrient conditions. 

Blue-green algae are the dominant phytoplankton group in the 

lake. While the quantities of nutrients and blue-green algae blooms have 

increased over the years, so have the rate of sediment accumulation and the 

amount of phosphorus stored in sediments. During the past 50 years, the 

annual rate of sedimentation has increased fourfold compared with earlier 

periods, resulting in a large in-lake store of phosphorus. 

Dominant zooplankton in the lake currently include water fleas 

(Cladocera sp.) and rotifers (Crisman and Beaver, 1988). Also present are 

benthic macroinvertebrate populations that are low in diversity and density 

and mostly comprise sludgeworms and midges. 

The lake’s cultural eutrophication shifted fish communities from sport 

fish to rough fish. Currently, gizzard shad and blue tilapia (Tilapia aurea) 

predominate, with a remnant sunfish population also present. Historically, 

Lake Apopka was a premier largemouth bass fi shing lake and contributed

Information on Point Sources in Planning Units 

Point sources discharging 

pollutants to surface water or 

ground water originate from 

discrete, well-defined areas such 

as a facility discharge from the 

end of a pipe, a disposal well, or 

a wastewater sprayfield. Point 

sources generally fall into two 

major types: domestic wastewater 

sources (which consist of 

sewage from homes, businesses, 

and institutions) and industrial 

Environmental Remediation 

Environmental remediation 

activities cover a broad spectrum 

of cleanup programs. These 

include state-managed hazardous 

waste, dry cleaning, and 

petroleum cleanup programs; 

as well as the federal Superfund 

and Resource Conservation and 

Recovery Act (RCRA) programs. 

These programs are designed to 

remediate ground water and soil 

contamination that pose a threat

include wastewater, runoff, 

and leachate from industrial or 

commercial storage, handling, 

or processing facilities). Landfills, 

hazardous waste sites, dry 

cleaning solvent cleanup program 

(DSCP) sites, and petroleum 

facility discharges are also 

considered point sources. These 

sites have the potential to leach 

to public health and the 

environment. 

The National Priorities List 

(NPL) is a consolidated list of the 

uncontrolled hazardous waste 

sites that pose the greatest threat 

to public health or the environment.

assessment, site inspection, 

and hazardous ranking system

potential for adverse impacts and 

Delineated Ground Water Contamination Areas 

The Department’s Delineation 

Program was established 

in response to the discovery 

of ground water contaminated 

by ethylene dibromide (EDB), a 

soil fumigant that was historically 

used in thirty-eight Florida 

counties to control nematodes 

in citrus groves and row crops. 

The program currently includes 

ground water contaminated by 

other pesticides, industrial solvents, 

and nutrients. However, 

the coverage of delineated areas 

in this program is not intended 

to include all sources of contaminated 

ground water in Florida. 

The Delineation Program is 

designed to ensure the protection 

of public health in consumption 

of potable ground water supplies 

and to minimize the potential 

for cross-contamination of adjacent 

ground water resources. 

Figure 2.8 shows ground water 

contamination areas in the Ocklawaha 

Basin. 

The Delineation Program’s 

primary responsibilities are as 

follows: 

• Delineate areas of known 

ground water contamination, 

• Implement a water well 

construction permitting/ 

application process that 

contaminants into ground 

water and surface water. 

Identifying the source of 

waterbody impairment is an 

important part of assessing

Nonpoint Sources and Land Uses 

Rainfall generates stormwater 

runoff. As it flows over the land 

and through the ground, runoff 

may carry nonpoint source pollution 

from many different sources 

to lakes, rivers, and estuaries in a 

watershed, and into ground water 

supplies. Nonpoint sources also 

include atmospheric deposition 

and leaching from agricultural 

lands, urban areas, and unvegetated 

lands. The pollutants in 

runoff often include fertilizers, 

bacteria, metals, sediments, 

petroleum compounds, and 

metals.


substantially to the local economy. Catfish and blue tilapia were important 

commercial species in 1990. The harvest of both species declined 

substantially by 1995. A 1997 evaluation of sport fi sh populations found 

that average total biomass and numbers of harvestable fish were lower or 

not improved from data collected from 1989 to 1991 (SJRWMD, 2001; 

Johnson and Crumpton, 1998). 

Alligator populations (Alligator mississippiensis) are believed to have 

been affected by the lake’s water quality, although the exact cause is not 

clearly understood. In 1981, a decline in juvenile alligators was noted 

and thought to be the result of a pesticide (dicofol) spill from the Tower 

Chemical Company. Elevated organochlorine pesticide levels were found 

in alligator eggs following the spill. An overall decline in the reproductive 

success or viability of eggs occurred. More recent evidence does not 

provide as conclusive a link between pesticides and declines in alligator egg 

viability. An increasing trend in egg viability and juvenile populations has 

been observed since 1989 (Rice and Percival, 1996). There are now two 

distinct populations of alligators and turtles in the northern and southern 

portions of the lake. Clutches from the southern portion have higher 

viability and production rates than clutches from the northern portion. 

Chapter 2 and Appendix B contain additional information on ecological 

resources in the planning unit. 

Water Quality Improvement Plans and Projects 

Waters will not be placed on the Verified List if the Department 

receives reasonable assurance that existing or proposed projects and/or 

programs are expected to result in the attainment of water quality standards 

or consistently improve water quality over time. Chapter 4 and 

Appendix C contain additional information on the requirements for 

reasonable assurance. 

No management plans or projects complying with the Department’s 

guidance for reasonable assurance have been provided for the 2002 list of 

impaired waters in the planning unit. It should be noted, however, that 

considerable work has been done in this unit by the SJRWMD to improve 

water quality through muck farm purchase and restoration, and through 

the SWIM Program. 

• Palatlakaha River Planning Unit 


The Palatlakaha River originates in Polk County in the Green Swamp 

and discharges into Lake Harris, draining about 223 square miles. Lake 

Lowery, Big Creek, and Little Creek drain into Lake Louisa, part of the 

Clermont Chain of Lakes, which are all connected by the Palatlakaha 

River. The planning unit also contains several additional lakes and 

wetlands. Figure 3.4 shows the individual waterbody segments assessed in 

the Palatlakaha River planning unit. Outstanding Florida Waters (OFWs) 

in the planning unit are provided in Table 2.3 by county, and shown in 

Figure 2.7.

parameter assessed, 9 remain on the Planning List as only potentially 

impaired, and 9 meet standards for all parameters assessed.

levels in several lakes, one potential impairment for lead in Lake Lowery, 

and fish consumption advisories for mercury in fi sh tissue in Lake 

Minnehaha Outlet (previously named Crystal Lake Outlet) and Lake 

Louisa Outlet. 

There are many more waters meeting standards for nutrients in the 

planning unit than there are either potentially or verified impaired for 

nutrients. Therefore, elevated nutrients do not appear to be a significant 

problem here. Low DO levels found in several lakes in the planning 

unit are probably not due to anthropogenic nutrient enrichment. The 

Palatlakaha River Planning Unit is generally characterized as a marshy, 

interconnected system of lakes, which ultimately drains to the Palatlakaha 

River. In marsh systems, lower DO concentrations are expected because 

of reduced water velocities and the decomposition of organic material. For 

graphical information on water quality trends in waters meeting standards 

in the planning unit, see Figure E.1 in Appendix E. 

The TSI for Lake Minneola and Lake Minnehaha has increased over 

the last 10 years, even though these lakes currently meet standards for DO 

and nutrients. Recently, the annual average TSI for Lake Minneola has 

been over 40. Both of these factors may indicate the beginning of nutrient 

enrichment. 

Lake Minnehaha Outlet and Lake Louisa Outlet are within a halfmile 

of U.S. 27 and the urbanized area of the city of Clermont. It is 

believed that mercury is entering these systems through nonpoint sources of 

pollution, and this warrants close attention for signs of continuing decline 

in water quality due to urbanization. 

A potential lead impairment in Lake Lowery is a concern because this 

waterbody is the farthest upstream in the Palatlakaha River drainage and 

the potential exists for adverse effects on downstream waters. The northern 

shore of the lake contains an old residential canal system that has most

urbanization from the communities of Haines City and Lake Alfred. This 

warrants attention to the potential for worsening water quality trends in 

Lake Lowery as these communities develop and expand. 


Permitted Discharges. There are no permitted point source surface 

water discharges in the Palatlakaha River planning unit. 

Land Use Considerations. Appendix G lists land uses in the basin 

by planning unit. Over half the land uses in the planning unit are fairly 

evenly divided between agricultural activities and wetlands. Of the 

agricultural activities, the two land uses covering the greatest area are 

citrus groves and rangeland. Agricultural land uses can be associated 

with nonpoint discharges of pollutants (pesticides, nutrients, and coliform 

bacteria) and eroded sediments. 


Only one species of rare and imperiled fish, the blackbanded sunfish 

(Enneacanthus chaetodon), has been documented in the Palatlakaha

DO, Nutrients 

Nutrients are the most pressing water quality concern in the Lake 

Griffin Planning Unit. Other potential impairments in the planning unit 

include low DO levels in canals, coliform bacteria in Haines Creek Reach, 

turbidity in Lake Griffin, metals in some of the lakes, and mercury in fi sh 

tissue as indicated by fish consumption advisories in the Ocklawaha River 

at Sunnyhill Farm and Swim Pond. 

Because of the numerous surface water interconnections among the 

waters of the Lake Griffin planning unit, differentiating the causes for their 

individual impairments is difficult. To be sure, however, the prevalence 

of septic tanks and muck farming activities on thousands of acres within 

these watersheds since the 1940s, have contributed significantly to nutrient 

enrichment, as well as to impairments in other associated parameter groups 

such as DO and BOD, total and fecal coliform bacteria, and turbidity 

and TSS. Muck farming areas in the planning unit included what is 

now known as the Lake Griffin Flow-Way (on the northeast side of Lake 

Griffin), Emeralda Marsh between Lake Griffin and Lake Yale, and 

the highly channelized area north of Lake Griffin historically known as 

Sunnyhill Farm. These areas are now in public ownership and are being 

restored by the SJRWMD. The Lake Griffi n Flow-Way at Emeralda Marsh 

is now a 1,250-acre wetland filtration system. For more information on the 

history and operation of muck farms, see the “Water Quality Summary” 

section of the Lake Apopka Planning Unit discussed.


103 

Other potential sources of nutrient enrichment in the planning unit 

are four permitted discharges (discussed in the Permitted Discharges and 

Land Uses section); however, the discharges from these facilities are small. 

Sediments are thought to act as sinks for phosphorus in many of 

the lakes in the Lake Griffin planning unit. Phosphorus sedimentation 

increased more than 20 times in Lake Griffin in a 100-year period, 

from 1895 through 1994, with the greatest increase from about 1950 

to the present. This period corresponds with the initiation of muck 

farming, increased urbanization, and discharges of wastewater into lakes. 

Phosphorus sedimentation was highest in the period from 1965 to 1994. 

Currently, a large fraction of sediment (more than 60 percent) is organic 

matter. Lake Griffin contains three distinct sedimentation zones: the 

southwest embayment, south basin, and north basin, with the south basin 

having relatively lower storage amounts and rates. The ratio of planktonic 

to benthic diatom microfossils has increased in recent sediments, which is 

thought to be an indicator of nutrient enrichment. Based on diatom ratios, 

it is inferred that from the 1980s to early 1990s was the period of greatest 

nutrient enrichment. 

The invasive alga Cylindrospermopsis raciborskii has increased in most of 

the interconnected waters throughout the Ocklawaha Basin. Lake Griffi n 

has the most severe algal problem in the Lake Griffi n planning unit, with 

95 percent of the phytoplankton population consisting of C. raciborskii. 

High chlorophyll a concentrations and algal blooms have been increasing in 

Lake Griffin since 1996. 

There are still some smaller lakes in the planning unit, with hydrologic 

connections to Lake Griffin, Haines Creek Reach, and Lake Yale, that are 

meeting standards for nutrients (TSI). These are Lake Mathews, Lake 

Idlewild, and Lake Unity. Analysis of 10-year trends, however, indicates 

that nutrient levels are increasing in these lakes. Farther north in the 

planning unit, Pendarvis Lake connects to the Ocklawaha River via the 

Pendarvis Lake Tributary, and the lake is meeting standards for nutrients 

(TSI). South Twin Lake, located northeast of Lake Yale, is also meeting 

standards for nutrients (TSI). Ten-year trend data for Lake Pendarvis 

were not available; however, the 10-year trend for South Twin Lake is 

improving. 

In addition to nutrient-related impairments in the planning unit, 

there are a few potential metals impairments. These are in Lake Mary 

(lead), West Clearwater Lake (copper, lead), Lake Yale (selenium), Swim 

Pond and the Ocklawaha River at Sunnyhill Farm (mercury in fish tissue, 

as indicated by fish consumption advisories in each). No specific sources 

of the metals are known in the watersheds of these waterbodies, except 

perhaps agriculture and long-term use of the waters for boating. 

There were no potential or verified impairments observed in the 

planning unit for biology (macroinvertebrate-based bioassessments), and 

three instances where biology met standards (Island Lake Outlet, Crescent 

Lake, and South Twin Lake). These lakes are small, relatively isolated 

lakes located north of the city of Umatilla, in an otherwise unimpacted 

area of the planning unit. For graphical information on water quality

trends in waters meeting standards in the planning unit, see Figure E.2 in 

Appendix E. 


Permitted Discharges. Four facilities in the Lake Griffi n Planning 

Unit have permits for surface water discharges. Golden Gem Growers/ 

Processors has a permit to discharge up to 2 mgd of cooling water and 

stormwater into a ditch that flows into Lake Yale and also a permit to 

discharge 0.8 mgd of effluent to a sprayfield. The city of Leesburg has a 

permit to discharge up to 3.5 mgd of treated domestic wastewater through 

underdrains from its sprayfields. These underdrains discharge to the 

Okahumpka Swamp. Cutrale Citrus has a conditional discharge permit 

that allows discharges only during a 1-in-10-year storm event. Dura Stress 

has a permit to discharge less than 0.01 mgd to Haines Creek Reach, but 

the discharge is very small. Several other discharges in the planning unit 

go to percolation ponds, sprayfields, or are redirected for reuse. 


facilities in the planning unit, with their design flows, as well as any 

landfi lls or solid waste facilities. 

Land Use Considerations. Appendix G lists land uses in the basin, 

by planning unit. The most significant land coverage in the planning 

unit is composed of forests and water. While waters originating in forests 

are sometimes highly tannic and low in DO, these are considered natural 

background conditions and not significant sources of pollution. 


Eagles are inhabiting wetlands and aquatic habitats in the Lake Griffi n 

planning unit fairly extensively. Surveys in 1999 found 11 active nests in 

the planning unit, concentrated around Lake Griffin and Lake Yale. 

The planning unit has a species rarity ranking of medium to low, 

though several rare and imperiled fish have been documented. A species 

of special concern, the Lake Eustis pupfish, is documented in Lake 

Griffin (WBID 2814) and Yale Canal (WBID 2807). The blackbanded 

sunfish is only documented in Nicotoon Lake (WBID 2789). Sport fi sh 

collections on Lake Griffi n during 1999 and 2000 found that populations 

of largemouth bass (Micropterus salmoides) and black crappie (Pomoxis 

nigromaculatus) were at low levels, and there were few juveniles to replace 

declining stock. Overall, sport fish constituted 63 percent of the total 

number of fish sampled, with bluegill (Lepomis macrochirus) representing 

57 percent of the total sport fi sh. Most bluegills (about 77 percent) were 

in the juvenile size class. The mean total biomass of sport fi sh collected in 

the fall of 1999 was 81 percent lower than comparable sport fish sampling 

in 1986. During the early 1990s, black crappie made up the largest part of 

Lake Griffin’s fishery, averaging 70 percent of total harvest and 75 percent 

of angler effort (Benton and Douglas, 1994). 

A lake drawdown in 1981 helped to reestablish some aquatic plants that 

provided fish habitat and in the short term benefited the fishery. By 1986, 

most new submerged aquatic vegetation had disappeared from the lake as a 

result of a variety of factors, including increased turbidity and aquatic weed

control of hydrilla. Macrophytes have declined in Lake Griffi n since the 

1950s, with the largest declines in the 1960s. By about 1975, the lake had 

shifted its trophic structure from macrophyte domination to phytoplankton 

domination. Chapter 2 and Appendix B contain additional information 

on ecological resources in the planning unit.

• Lake Harris Planning Unit 


The Lake Harris planning unit includes Lake Harris, Little Lake 

Harris, Lake Carlton, Lake Ola, Lake Beauclair, Lake Dora, Lake Eustis, 

and the canal systems that connect them. It also includes the Little 

Everglades Tributary, which connects the Little Everglades Swamp and 

Little Lake Harris. The unit, comprising about 240 square miles, also 

includes other small lakes and canals within its boundaries. Figure 3.5 

shows the individual waterbody segments assessed in the Lake Harris

It is apparent that nutrients are the major water quality concern in the 

Lake Harris planning unit. Other potential impairments in the planning 

unit include low DO levels in springs; high turbidity in Lake Denham; 

poor biological community structure in some of the sloughs, runs, and 

outlets from lakes and springs; and high metals concentrations in a few 

lakes. 

Like the waters in the Lake Griffin planning unit, many of the waters 

in the Lake Harris planning unit are interconnected through a series of 

human-made canals and natural tributaries and wetlands. Excess nutrients 

and other pollutants in one or more of these waterbodies can pollute 

the others, even in the absence of any specific pollution sources in the 

watersheds of individual waterbodies in the planning unit. 

Unlike the Lake Griffin planning unit, however, muck farms have been 

historically absent from the Lake Harris planning unit, except for one small 

farm on the north shore of Lake Harris itself that is being restored. Muck 

farming cannot be removed as a significant source of nutrient enrichment 

in the Lake Harris planning unit. The Lake Harris Chain of Lakes is 

connected to Lake Apopka through the Apopka–Beauclair Canal, and 

Lake Apopka, as stated earlier, has been significantly polluted by muck 

farming since the 1940s. Lake Apopka effectively acted as a sink for 

pollutants coming from these farms. These pollutants bound to sediments


111 

and, under high water conditions, were conveyed through the canal to the 

Lake Harris Chain of Lakes. In Lake Dora, phosphorus sedimentation has 

increased by a factor of 15 since 1900 and a factor of 4 since 1945. In Lake 

Eustis, phosphorus sedimentation has increased since 1930, but the largest 

increases have occurred since 1950. A shift in composition of diatom 

species was estimated to have started in Lake Eustis in the 1920s with the 

appearance of planktonic diatoms, which are more tolerant of eutrophic 

lake conditions. An evaluation of microfossil diatoms from this lake 

indicates that eutrophication has been progressive over the past century. 

Recent sediments contain more planktonic than benthic diatoms. 

Other potential sources of pollution in the Lake Harris planning unit 

include the following numerous small but rapidly growing communities 

that surround the waters in the planning unit: 

Leesburg 

Howey-in-the-Hills 

Astutula 

Tavares 

Mount Dora 

Eustis 

North of Lake Harris and Helena 

Run 

West of Little Lake Harris 

East of Little Lake Harris 

North of Lake Dora and the Dora 

Canal 

Northeast of Lake Dora 

North and East of Lake Eustis 

Residential (septic tanks and lawns) and urban runoff from these 

communities are also likely sources of nutrient enrichment in the individual 

verified waters of the Lake Harris planning unit (Fulton, 1995). A 

potential, but less significant, source of nutrient enrichment in the planning 

unit is a permitted discharge of 1 mgd from Silver Springs Citrus. 

In addition to nutrient-related impairments in the Lake Harris 

planning unit, there are a few potential metals impairments. These are in 

Lake Harris (lead and selenium), Lake Dora (silver and selenium), Lake 

Ola (lead), and Lake Eustis (lead and silver). No specific causes of metals 

impairment are known in the watersheds of these waterbodies, except 

perhaps long-term use of the lakes for boating, and the proximity of some 

of them to major roads. The south shore of Lake Eustis is less than a 

quarter mile from U.S. 441, a major thoroughfare through Lake County. 

Interestingly, no fish consumption advisories have been issued in the Lake 

Harris planning unit based upon mercury in fi sh tissue. 

There are many smaller lakes in the planning unit that do not have 

hydrologic connections to the verified waters listed above, and that are 

meeting standards for nutrients (TSI). These are East Crooked Lake, 

Idamere Lake, Lake Angelina, Lake Dixie West, Lake Gertrude, Lake 

Joanna, Lake May, Lake Nettie, Lake Saunders, Lake Spencer, Lake 

Woodward, and Peanut Lake. This supports the hypothesis of conveyance 

of nutrients through the interconnected waters of the Lake Apopka 

planning unit and the Lake Harris Chain of Lakes. 

Of the three springs in the planning unit (Blue Springs, Bugg Spring 

Run, and Holiday Springs), only Bugg Spring Run is on the Planning List 

for DO. The other two meet standards for DO. Low DO in Bugg Spring

112 


Run can be at least partially attributed to the influence of ground water, 

which is typically low in DO in the absence of any known impairment. 

For graphical information on water quality trends in waters meeting 

standards in the planning unit, see Figure E.3 in Appendix E. 


Permitted Discharges. One industrial wastewater facility is 

permitted to discharge to surface waters in the Lake Harris Planning 

Unit—Silver Springs Citrus, with a permitted discharge of 1 mgd. Two 

petroleum cleanup sites are also permitted for surface water discharges. 





by planning unit. The two land uses that cover the largest area in the 

planning unit are water and wetlands. The second most significant land 

uses in the planning unit are rangeland and residential housing, which can 

be associated with nonpoint discharges of pollutants (pesticides, nutrients, 

and coliform bacteria) and eroded sediments. 


The planning unit has a species rarity ranking of medium to low. 

Surveys in 1999 found 25 active eagle nests, concentrated around Lake 

Eustis, Lake Harris, Little Lake Harris, Dora Canal, and Lake Beauclair. 

Several rare and imperiled fish have been documented from the 

planning unit as well. A species of special concern, the Lake Eustis 

pupfish, is documented in Lake Eustis (WBID 2817B), Lake Harris 

(WBID 2838A), Lake Dora (WBID 2831), Lake Carlton (WBID 

2837B), and Dead River (WBID 2817C). The blacktip shiner (Lythrurus 

atrapiculus) also has been caught in the Dead River. The sport fishery in 

many of the larger, connected lakes has been negatively affected by declines 

in water quality and cultural eutrophication. The greatest sport fishery 

declines in Lakes Carlton, Beauclair, Dora, Eustis, and Harris occurred 

in the 1960s and 1970s. Limited current data are available, although it is 

suspected that these lakes have not greatly changed. 

The largemouth bass fi shery is probably the best indicator of declining 

health in Lake Harris. Data collected on the largemouth bass fi shery in 

Lake Harris from 1991 to 1992 indicated a drastic decline in the fi shery 

compared with data collected since 1966. The implementation of new 

largemouth bass size regulations in 1992, with reevaluation in 1994–1995, 

did not show an increase in the abundance of largemouth bass. More 

recent professional judgment indicates that the fishery has recovered to 

some extent (Johnson, 2000, personal communication). Chapter 2 and 

Appendix B contain additional information on ecological resources in the

through muck farm purchases and restoration. 

• Marshall Swamp Planning Unit 


The Marshall Swamp planning unit, which drains about 164 square 

miles, includes Lake Weir, Little Lake Weir, Smith Lake, and several 

other lakes. It also includes Marshall Swamp, Silver Springs, Silver River, 

and portions of the Ocklawaha River. Figure 3.6 shows the individual 

waterbody segments assessed in the Marshall Swamp planning unit. OFWs 

in the planning unit are provided in Table 2.3 by county and shown in

The major water quality concerns in the planning unit are reduced DO 

levels, nutrient enrichment, and metals impairments. Low DO in Silver 

Springs and downstream in Silver River is consistent with what is expected 

in spring-fed systems. Spring-fed systems are influenced by ground water, 

which is typically low in DO. 

Benthic habitats immediately downstream of springs are sometimes 

depauperate due to high flow and constant flushing of the area, which 

can lead to lower macroinvertebrate species densities and diversity. The 

freshwater scud Hyalella azteca is often the only macroinvertebrate species 

in high density in spring-fed systems. Biological data for Silver Run 

from 1992 and 1996 show consistent improvement, with SCI assessments 

ranging from poor (failed) in 1992 to good (passed) in 1993 to excellent 

(passed) in 1994, 1995, and 1996. 

The Ocklawaha River above the Daisy Creek waterbody segment 

begins at the Moss Bluff Lock and Dam and ends downstream at the 

confluence of Silver River with the Ocklawaha River. This segment 

is essentially the beginning of the lotic (moving water) portion of the 

Ocklawaha River system. It has received large sediment loads and nutrientladen 

water over the years from muck farming in the highly channelized 

Sunnyhill Farm area located immediately upstream. Sunnyhill Farm is 

now being restored by the SJRWMD. The lock and dam at Moss Bluff 

have reduced water flow to this portion of the Ocklawaha River somewhat, 

allowing waters coming from the Sunnyhill Farm area to be filtered to some 

degree in the Ocklawaha Prairie located downstream of the lock and dam. 

Even so, the prairie is acting more as a sink than a filter due to reduced flow 

through it. The natural flow through the Ocklawaha Prairie is also being 

restored by the SJRWMD. 

Though perhaps not yet evident in this stretch of the Ocklawaha 

River, increased urban impact to the river is expected in the near future, 

and warrants close attention. The limits of the city of Ocala are about six 

miles from the shores of the Ocklawaha River here. According to the U.S. 

Bureau of the Census, Ocala is one of the fastest growing communities 

in Florida. Since 1960, Marion County has experienced tremendous 

manufacturing and industrial growth. In 1995, Ocala was declared an “All 

America City” by the National Civic League, and the nation’s fi fth most 

desirable place to live by Money magazine. In 1999, Ocala/Marion County 

was recognized by the U.S. Department of Agriculture census as the “Horse 

Capital of the World” and as having more horses and ponies than any other 

county in the nation. Nearly 29,000 residents are employed in the county’s 

thoroughbred industry alone. 

One of the greatest natural resources in the planning unit is Silver 

Springs. This spring system is a large aggregate of artesian boils, which 

collectively have the largest discharge of any nontidal spring system in 

Florida, averaging about 525 mgd (Phelps, 1994). The springs provide 

nearly all of the water that recharges the aquifer in the Ocklawaha Basin 

and they provide, via the Silver River, 80 percent of the flow in the 

Ocklawaha River downstream of its confluence with the Silver River 

(Magley, 2003, personal communication). The extent to which nitrate 

from the springs is impacting the Ocklawaha River, and also the St. Johns

118 


River, to which the Ocklawaha River connects farther downstream, is still 

in question. 

Studies were done in 1998–1999 by the Department to document 

nitrate concentrations in the Ocklawaha River and to determine its decay 

rate as it moves downstream. A sharp increase in nitrate concentrations in 

the Ocklawaha River was recorded downstream of its confluence with the 

Silver River, supporting contributions of nitrates from the springs. Flow 

and nitrate data from a stretch of the river from Conner to Eureka were 

used to estimate velocities and nitrate decay from Eureka to the Kirkpatrick 

Dam at the Rodman Reservoir. Under the assumptions of full restoration 

of the reservoir to preconstruction conditions and a low flow condition of 

600 cubic feet per second, it was estimated that 51.7 percent of the nitrate 

entering the Ocklawaha River at Eureka would reach the Kirkpatrick 

Dam. From there it would have to travel another 16 miles or so to reach 

the St. Johns River above Little Lake George. More information on the 

restoration of Rodman Reservoir is provided in the “Rodman Reservoir 

Planning Unit” section of this report. 

Other water quality concerns in the Marshall Swamp planning unit 

include high nutrient and metals concentrations in Lake Weir and fish 

consumption advisories for mercury in fish tissues in Smith Lake and 

the Ocklawaha River above Daisy Creek. The annual nitrogen load 

to the Lake Weir watershed doubled between the 1880s and the mid- 

1960s (Crisman et al., 1992). While nitrogen loads have declined since 

the 1960s, phosphorus loads increased during the 1980s. Phosphorus 

also accumulated in sediment at much higher rates in the 1980s than in 

the prior historical record, creating a flocculent sediment bottom. Also 

of note are water level changes in Lake Weir, which has declined since 

1983 (Crisman et al., 1992). This would serve to concentrate nutrients. 

Significant nutrient sources to Lake Weir include atmospheric deposition, 

residential runoff, agriculture, and septic tanks (Fulton, 1995). 

Atmospheric deposition and industrial runoff are believed to be sources 

of elevated metals concentrations in Lake Weir, Smith Lake, and the 

Ocklawaha River above Daisy Creek. There are six airports located within 

1.5 to 5 miles of Smith Lake, Lake Weir, and the Ocklawaha River at Moss 

Bluff: Martin Marietta Ocala Heliport, McMechen Airport, Lake Weir 

Seaplane Base, Jordan Airport, Jordan Seaplane Base, and Jordan Heliport. 

Historical runoff of metal-containing fuels from these facilities is likely. 

In addition, Little Lake Weir, which is connected to Lake Weir, has an 

old canal system on the north shore, in which metals could have been 

historically contributed by boats powered by metals-based fuels. 

Other than high metals in Smith Lake, it is otherwise in good shape. 

It was tested and met standards for nutrients (TSI). The Ocklawaha River 

above Daisy Creek met standards for fecal coliform bacteria and turbidity. 

Silver River met standards for nutrients (chlorophyll a) and turbidity and is 

not believed to be impaired for BOD.

the planning unit. The second most significant land use is low-density

• Florida Ridge Planning Unit 


The Florida Ridge planning unit includes Fairfield Sink, Priest 

Prairie Drain, portions of the Silver River, and several noncontributing 

areas. Most of these waters do not have surface water drainage into the 

Ocklawaha, but rather, drain to ground water. The planning unit is about 

691 square miles. Figure 3.7 shows the individual waterbody segments 

assessed in the Florida Ridge planning unit.

Of the seven waterbody segments in the Florida Ridge planning unit, 

none has any data of any type in the planning or verification periods; 

therefore, none of them could be assessed under the IWR. There are 

several small lakes and ponds in the planning unit, however, particularly in 

the Noncontributing Area west of Lake Wauberg, Orange Lake, Newnans 

Lake, and Paynes Prairie (in the Orange Lake planning unit). Attention

by planning unit. Approximately 30 percent of the land uses in the planning 

unit are cropland and pastureland. Forests and tree plantations 

comprise another 36 percent of land uses. Agricultural land uses such as 

cropland, pastureland, and tree plantations, can be associated with nonpoint 

discharges of pollutants (pesticides, nutrients, and coliform bacteria) 

and eroded sediments. 


The Florida Ridge is largely an internally drained area with little 

developed, connected surface hydrography, but rather, a well-developed 

ground water or subsurface flow system. Primary discharge points for 

ground water are Silver Springs to the Ocklawaha River and Rainbow 

Springs to the Withlacoochee River. 

Imperiled and rare aquatic species associated with ground water in the 

planning unit include the light-fleeing cave crayfish (Procambarus lucifugus) 

and pallid cave crayfi sh (Procambarus pallidus). 

Very rare or locally found species of plants and animals inhabiting 

the planning unit include the Florida mountain mint (Pycnanthemum 

fl orid anum), Florida scrub jay (Aphelocoma coerulescens), gopher tortoise 

(Gopherus polyphemus), and short-tailed snake (Stilosoma extenuatum). 

Other species of interest include the bald eagle (Haliaeetus leucocephalus), 

eastern indigo snake (Drymarchon corais couperi), wood stork (Mycteria

• Rodman Reservoir Planning Unit 


The Rodman Reservoir planning unit is approximately 472 square 

miles. It includes the Rodman Reservoir itself, but also contains many 

other lakes besides Rodman Reservoir (e.g., Halfmoon Lake, Lake 

Charles, Redwater Lake, North Lake, Lake Bryant, Mill Dam Lake, and 

Lake Jumper). It also includes Eaton Creek, Daisy Creek, Mill Creek, 

Bruntbridge Brook, Deep Creek, Sweetwater Creek, and portions of the 

Ocklawaha River. Figure 3.6 shows the individual waterbody segments 

assessed in the Rodman Reservoir Planning Unit. The OFWs in the 

planning unit are provided in Table 2.3 by county and shown in 

Figure 2.7.

concentrations in several lakes and the Rodman Reservoir (also known as 

Lake Ocklawaha), as well as low DO concentrations and poor biological 

community structure in some lakes, creeks, and river segments. 

As shown above, only Lake Bryant and the Ocklawaha River above 

Rodman Reservoir (the main lotic water in the planning unit) are verified 

impaired for nutrients. The origin of the nutrient impairment in Lake 

Bryant is unknown. All the other lakes for which there were sufficient 

nutrient data for assessment (12 lakes) met standards for chlorophyll a, 

even the Rodman Reservoir itself. Most of these lakes are in the same 

watershed as Lake Bryant or are in similar watersheds in terms of land uses. 

While most of the waters in the planning unit got a clean bill of 

health for nutrients, they did not fare as well for metals. Waters that were 

potentially impaired for metals were Lake Charles (lead), Penner Ponds 

(copper, lead and zinc), Daisy Creek (iron), and the Ocklawaha River

above the Rodman Reservoir (cadmium, lead, selenium, silver). Fish 

consumption advisories for mercury in fish tissue were issued for Lake 

Eaton, Rodman Reservoir, Mill Dam Lake, the Ocklawaha River above the 

Rodman Reservoir, and the Ocklawaha River above its confluence with the 

St. Johns River. Figure 3.8 shows the area of the planning unit in which 

high metals concentrations were found. 

The prevalence of high metals in the Ocklawaha River above the 

St. Johns River and also above Rodman Reservoir are believed to be due 

to the effects of damming the river in two places, at Eureka and at the 

Rodman Reservoir. Damming a river can contribute to a reduction in 

water flow through the system and the accumulation of fine-grained 

sediment to which metals can bind. Under normal flow conditions, metals 

and other pollutants are flushed from the river on a continual basis before 

they have the chance to settle out of the water column and bind to benthic 

sediment. Metals can be picked up in the water column again when the 

sediments to which they are bound are resuspended in the water column 

due to turbulence, or when they dissociate from sediments and go back 

into solution under conditions of reduced pH. Sources of metals in the 

basin are many, including long-term use of the river by boats fueled with 

metal-based fuels, industrial and domestic runoff, agriculture, atmospheric 

deposition, and roadway runoff. 

Many of the waterbody segments assessed in the planning unit met 

standards for one or more parameters. Six met standards for biology (based 

on macroinvertebrate bioassessments) and as stated earlier, 12 segments 

met standards for nutrients. For graphical information on water quality 

trends in waters meeting standards in the planning unit, see Figure E.4 in 

Appendix E. 

The “story” of water quality in the Ocklawaha Basin must be told in 

light of its many special features and land uses, and of the alterations this 

system has undergone since the 1800s. Two of the most significant features 

in the basin are Silver Springs and the Rodman Reservoir. Their combined 

effects have dictated the overall water quality of the Ocklawaha River since 

the 1960s. 

Silver Springs is a large aggregate of artesian boils located at the 

headwaters of the Silver River east of the city of Ocala. The collective 

discharge of these boils is the largest of any nontidal spring system in 

Florida, averaging about 525 mgd (Phelps, 1994). The springs provide 

nearly all of the water that recharges the aquifer in the Ocklawaha 

Basin (Murray, 1999), and they provide nearly 80 percent of the flow 

in the Ocklawaha River downstream of its confluence with the Silver 

River (Magley, 2003, personal communication). Studies conducted in 

1998–1999 by the Department, as well as studies by many others, have 

documented significant nitrate contributions to the Ocklawaha River 

from Silver Springs (see the “Water Quality Summary” section for the 

Marshall Swamp Planning Unit in this report). 

High nitrates coming from the springs, as well as numerous other 

nutrient sources throughout the river’s watershed, such as upstream 

lakes (see the Water Quality Summaries for each planning unit in this 

report), have contributed to the nutrient enrichment of the Ocklawaha

128

River. In 1968 the Rodman Reservoir was completed in the downstream 

reaches of the Ocklawaha River as a means to redirect water in the 

Cross-Florida Barge Canal, which at that time was under construction 

to provide a navigation route across the state. The Kirkpatrick Dam, 

located downstream of the reservoir, held the water back and ultimately 

caused the flooding of 9,000 acres of forested floodplain at the present 

site of the reservoir and upstream of the reservoir. It also slowed down 

the flow of water throughout the course of the Ocklawaha River, 

causing sedimentation, nutrient enrichment, reduced DO, high metals 

concentrations, and a whole host of manifestations of these water quality 

conditions, including repeated and massive fish kills in the reservoir and 

algal blooms throughout the Ocklawaha River watershed. 

The Cross-Florida Barge Canal was deauthorized in 1991 due to 

widespread environmental concerns, and in 1992 plans were under way 

to restore the area upon which the reservoir now stands. Concerns were 

raised, however, about restoring the free flow of water, with a heavy 

load of nitrates from Silver Springs, down the Ocklawaha River to the 

St. Johns River. The Ocklawaha River is the principal tributary to the 

St. Johns River. A compromise was reached that calls for a partial and 

phased approach to restoration, which will allow some of the human-made 

structures currently in place to remain while restoring thousands of acres 

of floodplain and water quality throughout the system to preconstruction 

condition. The restoration is expected to improve water quality throughout 

the Ocklawaha River watershed. Among the less discussed, but equally 

important, benefits of the restoration are the following: 

• Restoring historical water clarity in the Ocklawaha River system to 

allow the growth of beneficial plants and healthy fi sh and invertebrate 

populations, 

• Bringing water levels down in the Rodman area to allow access to 

large freshwater springs that have been submerged since construction 

of the dam, 

• Reducing manatee mortality due to entrainment in the locks and 

sluice gates of the Kirkpatrick Dam, and 

• Reducing the need to use herbicides and other measures to control 

exotic weeds that have plagued the Rodman Reservoir. 

Figures 3.9 and 3.10 show spatial and temporal trends in flow and 

water quality for selected parameters of concern in the Ocklawaha Basin, 

from the Moss Bluff Lock and Dam to Orange Springs. 


Permitted Discharges. There are no permitted surface water 

discharges in the Rodman Reservoir planning unit, but there are several 

discharges in the planning unit that go to percolation ponds or sprayfields 


Land Use Considerations. Appendix G lists land uses in the

75 percent of the land coverage in the planning unit. The second most

significant land use by area is low-density residential housing, which can be 

associated with nonpoint discharges of pollutants (pesticides, nutrients, and 

coliform bacteria) and eroded sediments. 


The Rodman Reservoir planning unit is ranked as medium-low to 

medium in species rarity for stream fi sh, though several rare and imperiled 

fish have been documented. The bluenose shiner (Pteronotropis welaka), 

river goby (Awaous banana), and tessellated darter (Etheostoma olmstedi 

maculatips) have been found in the Ocklawaha River (WBID 2740A 

and 2740C); it is, however, uncertain whether the bluenose shiner is 

still present in the river. The bluenose shiner and tessellated darter are 

also documented in the Rodman Reservoir itself (WBID 2740B). The 

tessellated darter also has been recorded in Eaton Creek (WBID 2771). 

The blackbanded sunfish has been found in Clear Lake, North Lake, and 

Mill Dam Lake (WBIDs 2782A, 2775B, and 2779). 

The construction of the Kirkpatrick Dam, Rodman Reservoir, and the 

Cross-Florida Barge Canal has changed the lower Ocklawaha River fishery. 

Fish species composition has shifted from fewer riverine fi sh species to 

more lake fish species. Rodman Reservoir is an acclaimed recreational 

largemouth bass fishery. The tailrace area of Kirkpatrick Dam provides a 

substantial catfish fishery as well (FDEP, 1997). The dam and reservoir 

have also had some negative effects on fish populations. Large fi sh kills 

have resulted from low DO levels occurring periodically in the Rodman 

Reservoir. The current configuration of the lock and dam might limit or 

restrict access by some migratory fish to the Ocklawaha River, most notably 

that of the American eel (Anguilla rostrata) and possibly that of the striped 

bass (Morone saxatilis), mullet, and American shad (Alosa sapidissima). 

The river is believed to be the original spawning area for the endangered 

shortnose sturgeon (Acipenser brevirostrum) (Hoehn, 1998), but spawning 

has not been recently documented. 

Fish collection in 1994 yielded a higher percentage of gizzard shad 

in Rodman Reservoir and the Cross-Florida Barge Canal compared with 

samples collected below the Kirkpatrick Dam. Fish species diversity 

was higher below the dam. The relative abundance of seven sport 

fish—largemouth bass, black crappie, redbreast sunfi sh (Lepomis auritus), 

bluegill, redear sunfish (Lepomis microlophus), warmouth (Lepomis gulosus), 

and spotted sunfish (Lepomis punctatus) —in the lacustrine zone of the 

Rodman Reservoir was lower between 1986 and 1994 (by 66.7 percent) 

than between 1960 through 1989 (FDEP, 1997). 

Osprey (Pandion haliaetus) are the prominent fish-eating bird of prey 

in the planning unit. Five eagle nests were discovered in the planning unit 

in 1999. 

Hydrilla (Hydrilla verticillata) has been a dominant submerged aquatic 

plant in the planning unit since 1974 and has since become a serious 

invasive exotic plant management problem in Rodman Reservoir. Since 

the 1970s, water hyacinth (Eichhornia crassipes) and water lettuce (Pistia 

stratiotes) have also become prevalent problems. All three species are 

controlled through continual invasive plant management activities.

Numerous artesian springs flooded by the damming of the Ocklawaha 

River may have been historically available to the West Indian manatee 

(Trichechus manatus) as warm water refugia. The Buckman Lock and 

Kirkpatrick Dam were responsible for numerous manatee deaths from 

1974 through 1996 (Smith, 1997), but since that time, measures have been 

taken to prevent manatee entrainment in the lock system. Chapter 2 and 

Appendix B contain additional information on ecological resources in the 










guidance for reasonable assurance have been provided for the 2002 list 

of impaired waters in the planning unit. The restoration of the Rodman 

Reservoir and lower Ocklawaha River, however, are expected to improve 

future water quality conditions throughout the course of the Ocklawaha 

River. 

• Orange Creek Planning Unit 


The Orange Creek planning unit contains many creeks and lakes 

in approximately 602 square miles. The larger creeks include Tumblin’ 

Creek, Sweetwater Branch, Hogtown Creek, Possum Creek, Little Hatchet 

Creek, Lochloosa Creek, Lake Forest Creek, Prairie Creek, Little Orange 

Creek, Cabbage Creek, Orange Creek, and many others. The lakes include 

Bevens Arm, Lake Alice, Newnans Lake, Orange Lake, Little Orange Lake, 

Lochloosa Lake, and many others. This unit also includes sinks, such as 

Alachua Sink and Haile Sink, as well as Paynes Prairie and several springs. 

Orange Creek receives drainage from the basin and discharges directly to 

the Ocklawaha River through Rodman Reservoir. Sweetwater Branch and 

Hogtown Creek discharge to ground water through sinks. Figure 3.11 

shows the individual waterbody segments assessed in the Orange Creek 

planning unit. The OFWs in the planning unit are listed in Table 2.3 by 

county and shown in Figure 2.7.

Other potential impairments in the planning unit include unionized 

ammonia, BOD, TSS, turbidity, and metals. Most of the waters of concern 

in the planning unit lie in and around the city of Gainesville and in the 

southern portion of the planning unit near Orange Lake and Orange 

Creek. They are largely interconnected through a series of canals and 

natural tributaries, except Hogtown Creek, Possum Creek, and much 

farther east at Redwater Lake. A number of control structures restrict the 

flow of water among these waters, including a weir at the outlet of Orange 

Lake and another at the outlet of Newnans Lake. Gated culverts exist 

between Prairie Creek and Paynes Prairie and between Alachua Lake and 

Alachua Sink (SJRWMD, 1995). Pollutants are being freely conveyed 

through these connected waters, as evidenced by the similarity of their 

impairments and the degree to which they are impaired. This creates a 

problem in terms of identifying the origin of pollutants impairing any 

particular waterbody. 

The major water quality concerns in the planning unit are nutrient 

enrichment, low DO levels, and high coliform bacteria levels (in some 

areas). A number of the Verified or Planning Listed impairments associated 

with these constituents can be attributed to septic tanks, discharges from 

industrial and domestic wastewater facilities, agriculture, silviculture, 

atmospheric deposition, and urban and residential runoff. Septic tanks 

are prevalent in the basin and have been identified as significant sources 

of nutrients and bacteria in the planning unit (SJRWMD, 2000). An 

estimate of the density of septic tanks and wastewater facilities in the


141 

Gainesville area was provided by Gainesville Regional Utilities and is 

shown in Figure 3.12. The highest number of septic tanks is in the 

Possum Creek watershed (733), followed by Hogtown Creek (541). There 

are permitted domestic wastewater discharges to Sweetwater Branch and 

Lake Yale and permitted industrial wastewater discharges to Sweetwater 

Branch and Hatchet Creek that are thought to contribute nutrients, and 

possibly bacteria, to these waters. Nearly 50 percent of the fecal coliform 

data used in the assessment of Sweetwater Branch in this report exceeded 

400 counts per 100 milliliters of sample water. 

Macroinvertebrate-based bioassessments were conducted in 1991 

in Sweetwater Branch at a background site and a test site, upstream 

and downstream, respectively, of a power generating station, for which 

Sweetwater Branch is a receiving water. The test site did not meet the 

biological integrity criterion in Subsection 62-302.530(11), F.A.C. 

There were also two failed bioassessments in 1996 at two other sites in 

the waterbody. These impairments are believed to be due to habitat 

alteration as the result of nutrient enrichment and the accumulation of 

organic sediments. Channelization of portions of Sweetwater Branch and 

the occurrence of a duck pond in its upper reaches have contributed to 

downstream water quality problems. In addition, urban and residential 

runoff from the city of Gainesville to waters in and around the city also 

contributes nutrients (from lawn and golf course fertilization), bacteria, and 

metals contained in fuel for cars, trucks, and aircraft. 

Diversion of Prairie Creek from Paynes Prairie to Orange Lake, and 

construction of the Orange Lake Weir, Newnans Lake Dam, and three 

major highways (U.S. Highways 301 and 441, and I-75) have altered 

natural flow patterns and water level fluctuations in the planning unit. 

Conversion of wetlands along Orange Creek for agricultural use has 

also diminished water quality and habitat. Newnans Lake has become 

hypereutrophic and woody vegetation has spread over a part of Paynes 

Prairie as the result of some of these hydrologic alterations (SJRWMD, 

2000). Some of the TSI scores calculated for Newnans Lake as part of this 

assessment were as high as 100. Efforts are under way by the SJRWMD 

to identify causes of poor water quality and sediment accumulation in 

Newnans Lake (SJRWMD, 2000). 

In addition to nutrient- and coliform bacteria-related impairments 

in the Orange Creek Planning Unit, there are a few potential metals 

impairments. These are in Hatchet Creek (lead and iron), Orange Creek 

(silver and lead), Orange Lake (silver, lead, and mercury in fi sh tissue as 

indicated by a fish consumption advisory), and Lochloosa Lake (selenium). 

All of these waterbodies are either near a major roadway (U.S. 301 or 

U.S. 441), from which contaminated runoff could originate, or they are 

connected to waters that are near these sources. 

More importantly, perhaps, some of the current and historical 

industrial facilities in the planning unit have been associated with ground 

water and soil contaminated with metals such as lead, silver, chromium, 

cadmium, mercury, barium, arsenic, and copper. These include a 

machinery manufacturing plant (in operation; waste now being diverted 

to sewer system), two landfills (one in operation and used for construction

142 


Figure 3.12: Estimated Prevalence of Wastewater Facilities and Septic Tanks in the Gainesville Area


143 

debris; one out of operation and being remediated), a wood treatment 

facility (out of operation and slated for remediation), a law enforcement 

firing range (in operation; several tons of lead recovered in 1978; bullets 

with copper jackets now used) and an historical military facility with a 

plating shop (1,515 tons of debris and metals-contaminated soil removed in 

1997) (SJRWMD, 2003). 

The Sea Coast Railroad Company historically changed batteries in 

railroad crossing signals and disposed of the used batteries in Hatchet 

Creek near the city of Waldo. Hatchet Creek is a tributary to Newnans 

Lake. A study by the University of Florida School of Resources and 

Conservation in 1980 indicated that the disposed batteries were a source 

of toxic lead and mercury levels in fish-eating birds in the Newnans Lake 

watershed (SJRWMD, 2003). Though the disposal of batteries in Hatchet 

Creek is no longer occurring, this could still be a source of lead observed in 

the waters of Hatchet Creek today. Lead is of low solubility (EPA, 1976) 

and typically remains bound to soil particles and organic material under 

neutral pH water conditions. The aqueous solubility of lead ranges from 

500 µg/L in soft water to 3 µg/L in hard water (EPA, 1976). Varying 

water chemistry, with a shift toward the acidic pH range, can cause lead to 

become soluble. Once introduced into the environment, lead can therefore 

persist and leach slowly from soils over time, in the absence of any new 

sources. 

Despite the widespread problem of nutrient enrichment in the planning 

unit, there are several cases in which waters do meet standards for nutrients. 

These are Bevens Arm, Blue Lake, Cowpen Lake, Deerback Lake, Fanny 

Lake, Gillis Lake, Hatchet Creek, Higginbotham Lake, Lake Alice Outlet, 

McMeekin Lake, Morris Lake, North Twin Lake, Orange Creek, Riley 

Lake, Star Lake, Tumblin’ Creek, and Winnot Lake. Many of the lakes 

listed above are located in the Little Orange Creek area, are small, and are 

isolated from the other larger, interconnected lakes in the planning unit. 

Nine macroinvertebrate-based bioassessments (SCIs) were performed 

in Orange Creek from 1992 to 1998, and all scores were excellent, but 

chemical trend data indicate declines in water quality in these waters. For 

graphical information on water quality trends in waters meeting standards 

in the planning unit, see Figure E.5 in Appendix E. 


Permitted Discharges. The Orange Creek planning unit has seven 

permitted surface water dischargers—four domestic wastewater treatment 

plants and three industrial facilities. The Gainesville Regional Utilities 

Main Street Wastewater Treatment Plant (WWTP) has a permitted capacity 

of 7.5 mgd for its advanced secondary effluent, which is discharged to 

Sweetwater Branch. The Gainesville Regional Utilities Kanapaha Reclamation 

Facility has an NPDES permit for the discharge of 10 mgd of 

advanced secondary treated effluent to surface waters, but the effluent is 

actually discharged to four deep injection wells and not to surface water. 

Feldspar Corporation has a permit to discharge up to 8.18 mgd of effluent 

from its settling ponds. The discharge from the Feldspar facility eventually 

enters Cabbage Creek. In the Hatchet Creek waterbody segment, the Flor-

144 


ida Department of Transportation previously had a permit to discharge up 

to 1.5 mgd of effluent from its Fairbanks air-stripping facility. The other 

three facilities all have permitted discharges less than 0.1 mgd. Several 

other discharges in the planning unit go to percolation ponds or sprayfields 






by planning unit. Forests, tree plantations, and wetlands constitute 

approximately 60 percent of the land uses in the planning unit. The 

second most significant land use is for low- and medium-density residential 

housing, which can be associated with nonpoint discharges of pollutants 

(pesticides, nutrients, and coliform bacteria) and eroded sediments. 


The Orange Creek planning unit is noted for its ecological significance 

and economically important sport fisheries. Orange and Lochloosa Lakes 

have long-established reputations for largemouth bass and black crappie 

fisheries. Orange Lake also supports commercially important catfi sh, 

alligator, and turtle harvests. Low water levels since 1999 and a decline in 

water quality are affecting the use and economic value of these fisheries. 

Eagle nest surveys in the planning unit in 1999 revealed 40 active 

nests, which are concentrated around Prairie Creek and Lochloosa Lake, 

Orange Lake, and the River Styx. The basin is one of the top 5 eagle 

nesting areas in Florida and has been identified by the FWC as one of 

13 important nest clusters in the state needed to ensure the survival 

of the species (Nesbitt, 2001, personal communication). Ospreys are 

concentrated in the same general area. 

The Orange Lake and River Styx areas also provide important 

wintering waterfowl habitat (Allen, 1986). The River Styx area has one 

of the state’s most successful wood stork rookeries, established at least 

80 years ago. Wood storks (Mycteria americana) are an indicator of the 

biological integrity of wetlands (Allen, 1986). They forage for fi sh using a 

groping technique that requires high fish densities. As a result, any factor 

that reduces fish density, such as changes in water quality, loss of habitat, 

or altered hydroperiods, may adversely affect wood storks (Allen, 1986). 

Paynes Prairie and the areas around Orange Lake and Lochloosa Lake 

provide nesting habitat for a large concentration of about 1,200 migratory 

sandhill cranes (Grus canadensis pratensis). Bird Island and, more recently, 

Red Bird Island in Orange Lake provide important habitats for wading 

bird rookeries (Lasi et al., 1996; Nesbitt, 2001, personal communication), 

although wading bird activity recently declined because of low water levels. 

Floating islands and floating marshes are present in deeper water areas 

of Orange Lake. These unique habitats are composed of suspended mats 

of vegetation. The islands vary in size from a few square feet to several 

acres and move about freely. These floating islands and marshes provide 

important habitat for numerous bird, reptile, and amphibian species. As


145 

many as 23 bird species have been found in the floating islands and 36 bird 

species on the floating marshes (Sieving and Schaefer, 1997). 

The stream fish rarity ranking for the planning unit is medium to low, 

though the rare and imperiled blackbanded sunfish is found in Orange 

Lake (WBIDs 2749 and 2761). Also, the tessellated darter has been 

recorded as being in Orange Creek (WBID 2747). 

Several waters in the planning unit have been affected by changes 

in plant and algal communities. Hydrilla is a problem on Orange Lake 

and Lochloosa Lake. More recently, algal densities and chlorophyll a 

concentrations in Lochloosa Lake have increased. Major vegetation shifts 

have been observed since 1970 on the north central portion of Paynes 

Prairie. Algal blooms and high chlorophyll a levels are present in Newnans 

Lake as well. Chapter 2 and Appendix B contain additional information 

on ecological resources in the planning unit. 









guidance for reasonable assurance have been provided for the 2002 

list of impaired waters in the planning unit. The SJRWMD has done 

considerable work, however, to improve water quality through restoration 

of muck farm lands located in the watershed of Orange Creek, as well as 

to identify causes of poor water quality and sediment accumulation in 

Newnans Lake (SJRWMD, 2000). The Orange Creek Basin Partnership 

was formed in 1997 to address water quality and stormwater issues in 

the Orange Creek Planning Unit, including habitat and water quality 

assessment of the streams in the planning unit (Shuman, Richardson, and 

Lasi, 2000). Members of the partnership include the SJRWMD (lead 

agency), Gainesville Regional Utilities, City of Gainesville Department of 

Public Works, Alachua County Environmental Protection Department, 

Alachua County Public Works Department, and the Department. In 1994, 

SJRWMD established the Orange Creek Basin Advisory Council to assist 

in developing a comprehensive watershed management plan. Lake levels 

and access, sediment accumulation, water quality and habitat protection are 

some of the issues the council addresses (SJRWMD, 2000).

Chapter 4: The Verified List of Impaired 

Waters 

Public Participation 

The Department has worked with a variety of stakeholders and 

held public meetings on developing and adopting the Verified Lists of 

impaired waters for the six Group 2 basins across the state. Table 4.1 

lists the statewide schedule for the development and adoption of the 

Group 2 Verified Lists, including the public meetings. The schedule for the 

Ocklawaha Basin is highlighted in boldface type. Appendix H contains 

documentation provided during the public comment period. 

Basin-specific draft Verified Lists of waters that met the requirements 

of the Impaired Surface Waters Rule (IWR) were made available to the 

public on July 12, 2002. The lists were placed on the Florida Department 

of Environmental Protection (Department) Total Maximum Daily Load 

(TMDL) Web site, at http://www.dep.state.fl.us/water/tmdl, and were also 

sent on request to interested parties by mail or via e-mail. 

Citizens were given the opportunity to comment on the draft lists in 

person and/or in writing. A total of 8 public meetings was held across the 

state, to encourage public participation on a basin-by-basin basis. The 

Department also accepted written comments for 45 days beginning 

July 12, 2002, and ending August 26, 2002. 

Following the public meetings for the Group 2 basins, which took 

place between July 19 and July 25, 2002, revised draft lists were made 

available to the public on August 7, 2002. The public had the opportunity 

to comment on these revised lists either in writing and/or at a final public 

meeting in Tallahassee. Comments received by August 2, 2002, were 

considered in preparing the revised draft lists. Comments on any of the 

lists were accepted and considered throughout the full comment period. 

The final basin-specific Verified Lists developed through the public 

participation process were adopted by Secretarial Order during the week 

of August 26–30, 2002, and were submitted to the U.S. Environmental 

Protection Agency (EPA) on October 1, 2002, as the state’s current 303(d) 

list of impaired waters.

requirements in the IWR (Rule 62-303, F.A.C.). Appendix A describes 

the legislative and regulatory background for the development of the 

Planning and Verified Lists. Appendix D contains a methodology that 

describes the criteria and thresholds required for both lists under the IWR. 

Any waters that do not have sufficient data to be analyzed in 

accordance with the requirements of the IWR remain on the 1998 303(d) 

list of impaired waters maintained by the EPA. These waters are not 

delisted, and they will be sampled during the next phases of the watershed 

management cycle so that their impairment status can be verified. 

U.S. Environmental Protection Agency Review of Florida’s 

Amended Section 303(d) List 

On June 11, 2003, the EPA released a Decision Document based on its 

review of the Department’s amendments to Florida’s 1998 Section 303(d) 

list. The EPA found that the Department’s Group 1 update substantially 

met the intent of Section 303(d) of the Clean Water Act and partially 

approved the submission. 

Applying its own evaluation methodology, the EPA proposed listing 80 

additional waterbody segments/pollutants for public comment by 

July 18, 2003. Under this methodology, approximately half of the added 

waters failed to meet water quality criteria for dissolved oxygen (DO), 

but no causative pollutant could be identified. Florida law precludes the 

Department from including such waters on its Verified List of impaired


149 

waters until the causative pollutant is known. The majority of the 

remaining waters were added to the list based on a different interpretation 

of the methodology for assessing potential impairment for bacteria. The 

Department agreed to apply this alternative methodology when assessing 

the next group (Group 2) of waterbodies for bacteria. 

The consequence of having the EPA add waters to Florida’s Section 

303(d) list is that the EPA would be obligated to propose TMDLs for 

these waters. However, the EPA has proposed assigning a “low” priority to 

these waterbodies, thus providing the Department an opportunity 

to investigate them further. The section on “Prioritization of Listed 

Waters” in Chapter 5 provides additional details on the criteria for high-, 

low-, and medium-priority waters. Information on the status of Florida’s 

amended Section 303(d) list is available on the EPA’s Web site at http: 

//www.epa.gov/region4/water/tmdl/florida/. 

Documentation of Reasonable Assurance 

Under the Florida Watershed Restoration Act (FWRA), the 

Department will not place impaired waters on the Verified List if 

reasonable assurance is provided that these waters will attain water 

quality standards in the future and will make reasonable progress towards 

attaining water quality standards by the time the next 303(d) list of 

impaired waters is scheduled to be submitted to the EPA. Reasonable 

assurance can be provided if existing or proposed technology-based 

effluent limitations and other pollution control programs under local, 

state, or federal authority are expected to result in the attainment of water 

quality standards. Examples include Surface Water Improvement and 

Management (SWIM) Program restoration projects that provide ongoing 

monitoring, and permitted facilities that upgrade to advanced treatment or 

remove discharges to surface waters. Table 4.2 lists the major elements of 

reasonable assurance, and Appendix C provides additional information. 

Though numerous other efforts are under way in the Ocklawaha Basin 

to identify and abate pollution, no management plans have been submitted 

to the Department that meet the reasonable assurance requirements 

described above. 

The Verified List of Impaired Waters 

Table 4.3 contains the Verified List of impaired waters for the 

Ocklawaha Basin, based on the water quality assessment performed for 

the October 2002 update to the 303(d) list. Figure 4.1 shows waters 

on the Verified List for the entire Ocklawaha Basin as of October 2002. 

For presentation purposes, the entire watershed for the listed water is 

highlighted. However, only the main water in the assessment unit has been 

assessed, and other waters in the watershed might not be impaired. Verified 

waters by planning unit were shown earlier in Tables 3.5 through 3.12

150 


and Figures 3.3 through 3.7 and 3.11. There were no data available for 

assessment of waters in the Florida Ridge planning unit; therefore, there are 

no verified impairments included in Table 4.3 for the planning unit.

2 In 1998, the EPA settled a lawsuit with the Earthjustice Legal Defense Fund concerning Florida’s TMDL program. The consent decree 

resulting from the lawsuit requires all TMDLs on the state’s 1998 Section 303(d) list of impaired waters to be developed according to 

the priority ranking and schedule established in the list. A number of Group 1 waters on the 1998 303(d) list were assigned high priorities 

with a TMDL development due date of December 31, 2002. While the Department has the lead responsibility for TMDL development 

in Florida, the consent decree stipulates that, where the Department fails to develop required TMDLs according to the schedule 

established in the 1998 303(d) list, the EPA shall assume this responsibility, and the EPA has nine months beyond the established 

schedule to do so. In the case of Group 1 waters with high priorities and 2002 TMDL due dates, the deadline is September 30, 2003.

159 

Since the October 2002 update of the 303(d) list, further data became 

available for assessment of the basin, and these data were used to update the 

listing status of waters. Table I.1 in Appendix I contains the listing status 

of all assessed waters in the basin as of January 2003. An Order containing 

the initial Verified List of Impaired Group 1 Waters (Verified List) was 

signed by the Department’s Secretary on August 26, 2002. Errors and 

omissions to the list were corrected in October 2002. On March 11, 2003, 

the Department’s Secretary signed an order amending the October 2002 

Verified List for the basin with the January 2003 listing status. It should 

be noted that changes in impairment status expressed in Table I.1 were 

not included in this Amended Order. The order was officially noticed in 

the March 28, 2003, edition of the Florida Administrative Weekly, which 

started a 21-day period to fi le a petition challenging the Order and a 

30-day period to appeal the Order. 

Pollutants Causing Impairments 

The major pollutants of concern in the planning units of the 

Ocklawaha Basin are the following: 








Nutrients 

DO, Nutrients 

DO, Nutrients 

DO, Nutrients 

DO, Nutrients, Coliform 

Bacteria 

DO, Nutrients 

DO, Nutrients, Coliform 

Bacteria 

Though some of these impairments, such as low DO, can be attributed 

partially to ground water influences from the many springs in the basin 

or naturally low DO in marshy areas, many are related to anthropogenic 

impacts. These include past agricultural practices such as muck farming; 

numerous hydrologic alterations to the Ocklawaha River and tributaries 

through the construction of dams, locks and channels; and urbanization of 

the basin. 

Adoption Process for the Verified List of Impaired Waters 

The Verified List must be submitted in a specific format (Section 

62-303.710, F.A.C.) before being approved by order of the Department’s 

Secretary. The list must specify the pollutant and concentration causing 

the impairment. If a waterbody segment is listed based on water quality 

criteria exceedances, then the list must provide the applicable criteria. 

However, if the listing is based on narrative or biological criteria, or 

impairment of other designated uses, and the water quality criteria are met, 

the Verified List is required to specify the concentration of the pollutant 

relative to the water quality criteria and explain why the numeric criterion 

is not adequate.

160 


For waters with exceedances of the DO criteria, the Department must 

identify the pollutants causing or contributing to the exceedances and list 

both the pollutant and DO in the Verified List. 

For waters impaired by nutrients, the Department is required to 

identify whether nitrogen or phosphorus, or both, are the limiting 

nutrients, and specify the limiting nutrient(s) in the Verified List. 

The Verified List must also include the priority and schedule for 

TMDL development established for a waterbody segment and note any 

waters that are being removed from the current Planning List. In future 

watershed management cycles, the list must also note waters that are being 

removed from any previous Verified List for the basin.


161 

Chapter 5: TMDL Development, Allocation, 

Implementation, and Monitoring Priorities 

Prioritization of Listed Waters 

Following the identification of impaired waters on the 303(d) list, the 

Florida Department of Environmental Protection (Department) determines 

priorities for developing Total Maximum Daily Loads (TMDLs) in 

Phase 3 of the watershed management cycle. When TMDLs are 

established, general allocations of pollutant load reductions are identified, at 

least to the level of point and nonpoint source categories. 

Because TMDLs cannot be developed for all listed waters during a 

single watershed management cycle, due to the number of verified impaired 

waters statewide, Section 62-303.500 of the Identification of Impaired 

Surface Waters Rule (IWR) (Rule 62-303, Florida Administrative Code 

[F.A.C.]) describes how the TMDL development schedule for verified 

waters is to be prioritized. The prioritization is to take into account the 

designated uses of the waters involved, the severity of impairments in 

each water, the risks involved to human health and aquatic life, and most 

specifically, to threatened and endangered species. 

Section 62-303.500 of the IWR stipulates the following criteria for 

assigning a TMDL development priority to verified waters (except those on 

the 1998 303[d] list). 

High-priority waters are 

• Waters in which the impairment poses a threat to potable water supplies 

or human health; or 

• Waters where the impairment is due to a pollutant regulated by the 

Clean Water Act and the pollutant has contributed to the decline or 

extirpation of a federally listed threatened or endangered species, as 

indicated in the Federal Register listing the species. 

Low-priority waters are 

• Waters that are listed before 2010 because of fish consumption 

advisories for mercury in fish tissue (due to the current insufficient 

understanding of how mercury cycles in the environment); 

• Man-made canals, urban drainage ditches, and other artificial waters 

that are listed only due to exceedances of dissolved oxygen (DO) 

criteria; or 

• Waters that were not on a Planning List of impaired waters, but were 

identified as impaired during the second phase of the watershed man-

162 


agement approach and were included in the Verified List, unless the 

segment meets the second high-priority criterion above. 

• The U.S. Environmental Protection Agency (EPA) has also proposed 

assigning to this category the list of additional waterbody segments 

that the agency developed using its own evaluation methodology, 

until the Department has had the opportunity to investigate these 

waterbodies further. 

All waters not designated high or low priority are medium priority and 

are prioritized based on the following factors: 

• The presence of Outstanding Florida Waters (OFW); 

• The presence of waters that fail to meet more than one designated 

use (e.g., aquatic life, primary contact and recreation, fi sh and 

shellfish consumption, and drinking water and protection of human 

health); 

• The presence of waters that exceed an applicable water quality criterion 

or alternative threshold with a greater than 25 percent exceedance 

frequency are a minimum confidence level or 90 percent; or 

• The presence of waters that exceed more than one applicable water 

quality criterion; administrative needs of the TMDL program, 

including meeting a TMDL development schedule agreed to with 

the EPA, basin priorities related to the Department’s watershed management 

approach, and the number of administratively continued 

permits in the basin. 

It should be noted that these priorities do not apply to waters on the 

1998 303(d) list. The Department retained the TMDL development 

priorities and due dates from the 1998 303(d) for waters listed there, 

because those priorities and due dates were stipulated by a Consent Decree 

and Settlement Agreement between EPA and the Earthjustice Legal 

Defense Fund. The only waters to which the above priorities apply are 

those which were identified and verified impaired solely through assessment 

according to the IWR, and of those in the Ocklawaha Basin, none fell 

into the high- or low-priority categories listed above. All of them were 

assigned priorities and TMDL due dates of “Medium/2007.” The Verified 

List (Table 4.3) provides the TMDL development priorities and due dates 

assigned to all verified waters in the Ocklawaha Basin as of October 2002; 

both 1998 303(d) listed waters and those that are not 1998 303(d) listed. 

TMDL Development 

During Phase 3 of the watershed management cycle, TMDLs will be 

developed for both point and nonpoint sources of pollutants in impaired 

waters and will be adopted by rule at the end of this phase.


163 

TMDL development involves determining the maximum amount of 

a given pollutant that a water can assimilate and still meet the applicable 

numeric or narrative water quality criterion for the pollutant. In most 

cases, this “assimilative” capacity will be determined using computer 

modeling (both hydrodynamic and water quality models) that predicts 

the fate and transport of pollutants in the receiving waters. Modeling for 

the typical TMDL will include model set-up, calibration, and verification, 

followed by a variety of model runs that determine the assimilative capacity 

of the water under worst-case conditions. 

State law and federal regulations require that TMDLs include a 

margin of safety (MOS) that takes into account “any lack of knowledge 

concerning the relationship between effluent limitations and water quality.” 

The EPA has allowed states to establish either a specific MOS (typically 

some percentage of the assimilative capacity) or an implicit MOS based on 

conservative assumptions in the modeling. To date, the Department has 

elected to establish an implicit MOS based on predictive model runs that 

incorporate a variety of conservative assumptions (they examine worst-case 

ambient flow conditions and worst-case temperature, and assume that all 

permitted point sources discharge at their maximum permitted amount). 

It is important to note that TMDLs will be developed only for the 

actual pollutants causing the impairment in the listed water. These are 

called the “pollutants of concern.” In Florida, the most commonly listed 

pollutants of concern are nutrients, sediments, and coliforms. TMDLs 

will not be developed for impairments not due to pollutant discharges— 

for example, natural conditions, physical alterations such as dams and 

channelization, or changes in the flow of the water. In other cases, a 

water may be deemed potentially impaired based on bioassessment data or 

toxicity data. In these cases, the Department must determine the actual 

pollutant causing the impairment before a TMDL can be developed. 

Schedule for TMDL Development 

The IWR specifies how the Department shall deem waters verified 

impaired. Due the verification requirements of the IWR, 1998 303(d) 

listed waters are retained on the Planning List that do not meet the data 

sufficiency requirements for verification under the IWR, or where the 

causative pollutant cannot be identified per Subsection 62-303.700(1) 

of the IWR. These waters will be evaluated during the next rotation of 

the basin management cycle, after adequate data can be generated for 

evaluation in accordance with the data sufficiency requirements of the 

IWR. The EPA, however, is not bound by the verification requirements 

of the IWR and may deem a water impaired based on its evaluation of 

existing data and information. In fact, the EPA is required by Consent 

Decree and Settlement Agreement to develop TMDLs, according to the 

schedule set forth in the 1998 303(d) list, where the Department is unable 

to do so. 

Through mutual agreement between the Department and the EPA, the 

Department has assumed responsibility for developing TMDLs for 

Group 1 waters that have been verified impaired under the IWR—both 

1998 303(d) listed waters and those that are not 1998 303(d) listed. The

164 


EPA has assumed responsibility for developing TMDLs for waters on the 

1998 303(d) list, with a TMDL development due date of 2002, that do 

not meet the verification requirements of the IWR. By Consent Decree, 

the EPA has until September 30, 2003, to complete them. In addition, the 

EPA has assumed responsibility for TMDL development in some waters for 

which resources exist within the EPA, which makes it more appropriate for 

the EPA to develop the TMDL rather than the Department. 

Table 5.1 contains all the 1998 303(d) listed waters in the Ocklawaha 

Basin with TMDL development due dates of 2002, as well as the 

parameters for which they are impaired and information on which 

agency will develop each TMDL. Some of these waters are categorized 

in the 1998 303(d) list as high priorities and some are categorized as low 

priorities. Many could not be verified impaired through analysis according 

the IWR because they did not meet the minimum data requirements for 

verification under the rule, so they are not shown in Table 4.3 (Verified 

List). The EPA has elected to develop TMDLs for them, however, in the 

absence of IWR verification. Table 5.1 also includes 1998 303(d) listed 

waters that will be delisted (for which TMDLs will not be developed), with 

explanations for their delistings under Subsection 62-303.720 of the IWR. 

In some cases, parameters or waterbodies with priority dates of 2007 are 

included in the 2003 TMDL workplan (Table 5.1), because those waters 

can be addressed by a TMDL model developed for connected waterbodies. 

It should be noted that Table 5.1 does not include any non-1998 

303(d) listed verified impaired waterbodies. Though these waters are 

verified impaired and require TMDLs, as stated earlier, they were given 

medium priorities and 2007 TMDL development due dates. The 

impairments in these waters will not, for the most part, be addressed this 

year, except where the work required can be coordinated with other, higher 

priority work. 

Figures K.1 through K.10 in Appendix K show the Priority 

Watersheds in which TMDLs will be developed in 2003. 

TMDL Allocation and Implementation 

Initial Allocation of Pollutant Loadings 

The Florida Watershed Restoration Act (FWRA) requires that a 

TMDL include the “establishment of reasonable and equitable allocations 

. . . among point and nonpoint sources . . . .” The Department refers to 

this as the “initial allocation,” which is adopted by rule. For the purposes 

of allocating the required pollutant loadings, the term “point sources” 

primarily includes traditional sources such as domestic and industrial 

wastewater discharges. 

Recent EPA guidance requires states to also include as point sources 

those stormwater systems that are covered by a National Pollutant 

Discharge Elimination System (NPDES) stormwater permit. However, 

NPDES permitted stormwater discharges are not subject to the same 

types of effluent limitations, cannot be centrally collected and treated, 

and typically have not invested in treatment controls to the same degree as

traditional point sources. Nonpoint sources include intermittent, rainfalldriven, 

diffuse sources of pollution associated with everyday human 

activities, including runoff from urban land uses, agriculture, silviculture, 

and mining; discharges from failing septic systems; and atmospheric 

deposition. 

These point and nonpoint definitions do not directly relate to whether 

a source is regulated. Some nonpoint sources such as stormwater systems 

are permitted under the regulatory programs of the Department or water 

management districts, while others, such as agricultural stormwater 

discharges, are not. This distinction is important because implementation 

of the allocations to nonpoint sources outside the authority of regulatory 

programs will require cooperation from dischargers to implement BMPs 

voluntarily. 

While a “detailed allocation” will ultimately be necessary to 

implement a TMDL fully, a key goal of the initial allocation is to assign 

responsibility for pollutant reductions between point and nonpoint 

sources. For point sources, allocations will be implemented through the 

Department’s NPDES wastewater and stormwater permitting programs. 

The implementation of nonpoint source reductions will be done through a 

combination of regulatory and nonregulatory processes. 

Initial allocations of pollutant loadings will also be made to historical 

sources (e.g., the phosphorus-laden sediments at the bottom of a lake) 

and upstream sources (those entering an impaired waterbody). Upstream 

sources include sources outside Florida, and these sources will receive 

reduced allocations similar to in-state sources. 

The FWRA provided direction for the allocation of TMDLs and 

directed the Department to provide guidance on the allocation process 

by establishing an Allocation Technical Advisory Committee (ATAC), 

consisting of representatives of key stakeholder groups. The committee’s 

report recommended a three-step process for developing initial allocations 

and addressed detailed allocations for nonpoint sources, stakeholder 

involvement, the use of best management practices (BMPs), and other 

TMDL implementation issues (FDEP, February 1, 2001). A copy of the 

ATAC report is available at http://www.dep.state.fl.us/water/tmdl/docs/ 

Allocation.pdf.


171 

Implementation Programs and Approaches 

The FWRA designates the Department as the lead agency in 

coordinating the implementation of TMDLs. Existing programs and 

approaches through which TMDLs may be carried out include the 

following: 

1. Permitting and other existing regulatory programs, such as 

NPDES permits, domestic and industrial wastewater permits, 

and stormwater/environmental resource permits. The municipal 

NPDES Phase 1 stormwater (MS4) permittee in the Ocklawaha 

Basin is Orange County and its co-permittees within the basin 

including the Florida Department of Transportation and the cities 

of Apopka and Winter Garden. Gainesville, Ocala, Lady Lake, 

Mt. Dora, Fruitland Park, Minneola, and the Leesburg-Tavares- 

Eustis area will most likely be included under municipal NPDES 

Phase 2 stormwater permits; 

2. Local land development codes; 

3. Nonregulatory and incentive-based programs, including BMPs, 

cost sharing, waste minimization, pollution prevention, new 

approaches to land use design and development, and public 

education; 

4. Basin Management Action Plans (B-MAPs) developed under the 

FWRA; 

5. Other water quality management and restoration activities—for 

example, Surface Water Improvement and Management (SWIM) 

plans approved under Section 373.456, F.S.; 

6. Pollutant trading or other equitable economically based 

agreements; 

7. Public works, including capital facilities; or 

8. Land acquisition. 

These programs and approaches will be carried out at local, regional, 

state, and possibly federal levels. TMDL implementation will require 

extensive stakeholder involvement throughout the state, and, in some cases, 

between Florida and other states. Appendix A provides additional details 

on the implementation programs and approaches listed here. 

Development of Basin Management Action 

Plans 

The FWRA authorizes the Department to develop B-MAPs for 

implementing TMDLs. These plans will be developed with extensive 

stakeholder input to build consensus on detailed allocations based on the 

initial general allocations to categories of discharges.

172 


The B-MAPs would contain final allocations, strategies for meeting 

the allocations, schedules for implementation, funding mechanisms, 

applicable local ordinances, and other elements. In cases where stakeholder 

consensus could not be reached on detailed allocations and/or a B-MAP 

within a reasonable time, the Department would develop the allocations. 

Once a B-MAP is developed, the Department will make it available for 

public review and comment. Guidance for the content and format of the 

B-MAPs is being developed; the plans are likely to include a description of 

both regulatory and nonregulatory approaches to meeting specific TMDLs.

Appendix A: Legislative and Regulatory Background on the 

Watershed Management Approach and the 

Implementation of TMDLs 

Federal and State Legislation on Surface Water Quality and TMDLs 

Clean Water Act 

Congress enacted the Clean Water Act in 1972 with the goal of restoring and 

maintaining the “chemical, physical, and biological integrity of the nation’s waters” (33 

U.S.C. § 1251[a]). The ultimate goal of the act is to eliminate the “discharge of [all] 

pollutants into navigable waters” (33 U.S.C. § 1251[a][1]). 

Section 305(b) of the Clean Water Act requires states to report biennially to the U.S. 

Environmental Protection Agency (EPA) on their water quality. The 305(b) assessment 

report provides information on the physical, chemical, biological, and cultural features of 

each river basin in Florida. This initial assessment provides a common factual basis for 

identifying information sources and major issues, and for determining the future changes, 

strategies, and actions needed to preserve, protect, and/or restore water quality. 

Understanding the physical framework of each basin allows the development of a 

science-based methodology for assessing water quality and an accurate picture of the 

waters that are most impaired or vulnerable to contamination. 

Section 303(d) of the Clean Water Act requires states to submit to the EPA lists of 

surface waters that do not meet applicable water quality standards and establish total 

maximum daily loads (TMDLs) for each of these waters on a schedule. A pollution limit 

is then allocated to each pollutant source in an individual river basin. 

A TMDL represents the maximum amount of a given pollutant that a waterbody can 

assimilate and meet all of its designated uses (see the sidebar on Florida’s surface water 

quality classifications for a listing of these classifications). A waterbody that does not 

meet its designated use is defined as impaired. 

NOTEWORTHY: FLORIDA’S SURFACE WATER QUALITY CLASSIFICATIONS 

Florida’s water quality standards program, the foundation of the State’s program of water quality 

management, designates the “present and future most beneficial uses” of the waters of the State 

(Section 403.061[10], F.S.). Water quality criteria, expressed as numeric or narrative limits for 

specific parameters, describe the water quality necessary to maintain these uses for surface 

water and ground water. Florida’s surface water is protected for five designated use 

classifications, as follows: 

Class I 

Class II 

Class III 

Class IV 

Class V 

Potable water supplies 

Shellfish propagation or harvesting 

Recreation, propagation, and maintenance of a healthy, well-balanced 

population of fish and wildlife 

Agricultural water supplies 

Navigation, utility, and industrial use (there are no state waters currently in 

this class)


Florida Watershed Restoration Act 

In 1998, the EPA settled a lawsuit with the environmental group Earthjustice over 

Florida’s TMDL Program. The Consent Decree resulting from the lawsuit requires all 

TMDLs on the State’s 1998 Section 303(d) list of impaired waters to be developed in 

thirteen years. If the State fails to develop the TMDLs, the EPA is required to do so. 

In response to concerns about the TMDL lawsuit and in recognition of the important 

role that TMDLs play in restoring state waters, the 1999 Florida legislature enacted the 

Florida Watershed Restoration Act (Chapter 99-223, Laws of Florida). The act clarified 

the Department’s statutory authority to establish TMDLs, required the Department to 

develop a methodology for identifying impaired waters, specified that the Department 

could develop TMDLs only for waters on a future state list of impaired waters developed 

using this new methodology, and directed the Department to establish an Allocation 

Technical Advisory Committee to address the allocation process for TMDLs. The act 

also declared Lake Okeechobee impaired and, as required under the TMDL Consent 

Decree, allowed the State to develop a TMDL for the lake (see the sidebar for a 

description of the legislation’s major provisions). 

NOTEWORTHY: THE FLORIDA WATERSHED RESTORATION ACT 

The Florida Watershed Restoration Act contains the following major provisions: 

• Establishes that the 303(d) list submitted to the EPA in 1998 is for planning purposes only. 

• Requires the Department to adopt 303(d) listing criteria (that is, the methodology used to 

define impaired waters) by rule. 

• Requires the Department to verify impairment and then establish Verified Lists for each 

basin. The Department must also evaluate whether proposed pollution control programs are 

sufficient to meet water quality standards, list the specific pollutant(s) and concentration(s) 

causing impairment, and adopt the basin-specific 303(d) list by Secretarial Order. 

• Requires the Department’s Secretary to adopt TMDL allocations by rule. The legislation 

requires the Department to establish “reasonable and equitable” allocations of TMDLs, but 

does not mandate how allocations will be made among individual sources. 

• Requires that TMDL allocations consider existing treatment levels and management 

practices; the differing impacts that pollutant sources may have; the availability of treatment 

technologies, best management practices (BMPs), or other pollutant reduction measures; the 

feasibility, costs, and benefits of achieving the allocation; reasonable time frames for 

implementation; the potential applicability of moderating provisions; and the extent that 

nonattainment is caused by pollution from outside Florida, discharges that have ceased, or 

alteration to a waterbody. 

• Required a report to the legislature by February 2001 addressing the allocation process. 

• Authorizes the Department to develop basin plans to implement TMDLs, coordinating with the 

water management districts, the Florida Department of Agriculture and Consumer Services,


the Soil and Water Conservation Districts, regulated parties, and environmental groups in 

assessing waterbodies for impairment, collecting data for TMDLs, developing TMDLs, and 

conducting at least one public meeting in the watershed. Implementation is voluntary if not 

covered by regulatory programs. 

• Authorizes the Department and the Florida Department of Agriculture and Consumer 

Services to develop interim measures and BMPs to address nonpoint sources. While BMPs 

would be adopted by rule, they will be voluntary if not covered by regulatory programs. If 

they are adopted by rule and the Department verifies their effectiveness, then implementation 

will provide a presumption of compliance with water quality standards. 

• Directs the Department to document the effectiveness of the combined regulatory/voluntary 

approach and report to the legislature by January 1, 2005. The report will include 

participation rates and recommendations for statutory changes. 

Determining Impairment Based on the State’s Impaired Surface Waters Rule 

Section 303(d) of the federal Clean Water Act and the Florida Watershed Restoration 

Act describe impaired waters as those waterbodies or waterbody segments that do not 

meet applicable water quality standards. “Impairment” is a broad term that includes 

designated uses, water quality criteria, the Florida antidegradation policy, and moderating 

provisions (see the sidebar below for explanations of these terms). 

The State’s Identification of Impaired Surface Waters Rule (Rule 62-303, F.A.C.) 

was developed in cooperation with a Technical Advisory Committee and adopted by the 

Florida Environmental Regulatory Commission on April 26, 2001. It provides a sciencebased 

methodology for evaluating water quality data in order to identify impaired waters, 

and it establishes specific criteria for impairment based on chemical parameters, the 

interpretation of narrative nutrient criteria, biological impairment, fish consumption 

advisories, and ecological impairment. The rule is available at 

http://www.dep.state.fl.us/water/tmdl/docs/AmendedIWR.pdf. 

The Impaired Surface Waters Rule also establishes thresholds for data sufficiency and 

data quality, including the minimum sample size required and the number of exceedances 

of the applicable water quality standard for a given sample size that identify a waterbody 

as impaired. The number of exceedances is based on a statistical approach designed to 

provide greater confidence that the outcome of the water quality assessment is correct. 

Waters that are identified as impaired through the Impaired Surface Waters Rule 

are prioritized for TMDL development and implementation. 

NOTEWORTHY: EXPLANATION OF TERMS 

Designated uses, discussed in an earlier sidebar, comprise the five classifications applied to 

each of the State’s surface waterbodies. 

Water quality criteria comprise numeric or narrative limits of pollutants.


The Florida Antidegradation Policy (Rules 62-302.300 and 62-4.242, F.A.C.) recognizes that 

pollution that causes or contributes to new violations of water quality standards or to the 

continuation of existing violations is harmful to the waters of the State. Under this policy, the 

permitting of new or previously unpermitted existing discharges is prohibited where the discharge 

is expected to reduce the quality of a receiving water below the classification established for it. 

Any lowering of water quality caused by a new or expanded discharge to surface waters must be 

in the public interest (that is, the benefits of the discharge to public health, safety, and welfare 

must outweigh any adverse impacts on fish and wildlife or recreation). Further, the permittee 

must demonstrate that other disposal alternatives (for example, reuse) or pollution prevention are 

not economically and technologically reasonable alternatives to the surface water discharge. 

Moderating provisions (provided in Rules 62-302.300[10], 62-4 and 62-6, F.A.C., and described 

in Rules 62-302.300, 62-4.244, 62-302.800, 62-4.243, F.A.C., and Sections 403.201 and 

373.414, F.S.) include mixing zones, zones of discharge, site-specific alternative criteria, 

exemptions, and variances. These provisions are intended to moderate the applicability of 

water quality standards where it has been determined that, under certain special circumstances, 

the social, economic, and environmental costs of such applicability outweigh the benefits. 

Determining impairment in individual waterbodies takes place in two phases. First, 

in each river basin the Department evaluates the existing water quality data, using the 

methodology prescribed in the Impaired Surface Waters Rule, to determine whether 

waters are potentially impaired. Waters found to be potentially impaired are included on 

a Planning List for further assessment under Sections 403.067(2) and (3), F.S. As 

required by Subsection 403.067(2), F.S., the Planning List is not used to administer or 

implement any regulatory program. It is submitted to the EPA for informational purposes 

only. 

The second step is to assess waters on the Planning List under Section 403.067(3), 

F.S., as part of the Department’s watershed management approach (described in the 

following section). The Department carries out additional data gathering and strategic 

monitoring, focusing on these potentially impaired waters, and determines—using the 

methodology in Part III, Rule 62-303.400, F.A.C.—if a waterbody is, in fact, impaired 

and if the impairment is caused by pollutant discharges. 

An Assessment Report is produced containing the results of this updated evaluation 

and a Verified List of impaired waters. The criteria for the Verified List are more 

stringent than those for the Planning List. The Department is required to develop 

TMDLs for waters on the Verified List under Subsection 403.067(4), F.S. A watershed 

management plan (called a Basin Management Action Plan) to reduce the amount of 

pollutants that cause impairments must also be produced and implemented. 

The Verified List is adopted by Secretarial Order in accordance with the Florida 

Watershed Restoration Act. Once adopted, the list is submitted to the EPA for approval 

as the State’s Section 303(d) list of impaired waters for the basin.


Implementing TMDLs 

The Watershed Management Approach 

The Department's statewide approach to water resource management, called the 

watershed management approach, is the framework for implementing TMDLs as required 

by the federal and state governments. The approach does not focus on individual sources 

of pollution. Instead, each basin is assessed as an entire functioning system, and aquatic 

resources are evaluated from a basinwide perspective that considers the cumulative 

effects of human activities. Water resources are managed on the basis of natural 

boundaries, such as river basins, rather than political or regulatory boundaries. Federal, 

state, regional, tribal, and local governments identify watersheds not meeting clean water 

or other natural resource goals and work cooperatively to focus resources and implement 

effective strategies to restore water quality. Extensive public participation in the 

decision-making process is crucial. 

The watershed management approach is not new, nor does it compete with or replace 

existing programs. Rather than relying on single solutions to water resource issues, it is 

intended to improve the health of surface water and ground water resources by 

strengthening coordination among such activities as monitoring, stormwater 

management, wastewater treatment, wetland restoration, land acquisition, and public 

involvement. 

By promoting the management of entire natural systems and addressing the 

cumulative effects of human activities on a watershed basis, this approach is intended to 

protect and enhance the ecological structure, function, and integrity of Florida’s 

watersheds. It provides a framework for setting priorities and focusing the Department’s 

resources on protecting and restoring water quality, and aims to increase cooperation 

among state, regional, local, and federal interests. By emphasizing public involvement, 

the approach encourages stewardship by all Floridians to preserve water resources for 

future generations. 

The watershed approach is intended to speed up projects by focusing funding and 

other resources on priority water quality problems, strengthening public support, 

establishing agreements, and funding multiagency projects. It avoids duplication by 

building on existing assessments and restoration activities and promotes cooperative 

monitoring programs. It encourages accountability for achieving water quality 

improvements through improved monitoring and the establishment of TMDLs. 

The Watershed Management Cycle 

As part of the Department’s watershed management approach, TMDLs will be 

developed, and the corresponding pollutant loadings allocated, as part of a watershed 

management cycle, which rotates through the State’s fifty-two river basins over a nineyear 

period. The cycle’s five phases are as follows:


• Phase 1: Preliminary Watershed Evaluation. For each river basin, a Status Report 

is developed, containing a Planning List of potentially impaired waters that may 

require the establishment of TMDLs. The report characterizes each basin’s 

hydrologic, ecological, and socioeconomic setting as well as historical, current, and 

proposed watershed management issues and activities. It also contains a preliminary 

evaluation of major water quality parameters, water quality issues by planning unit, 

an evaluation of ecological resources, and basinwide pollutant loading trends related 

to land uses. At the end of Phase 1, a Strategic Monitoring Plan is developed. 

• Phase 2: Strategic Monitoring and Assessment. Additional data are collected 

through strategic monitoring and uploaded to STORET. The data are used to verify 

whether potentially impaired waters in each basin are impaired and to calibrate and 

verify models for TMDL development. At the end of Phase 2, an Assessment 

Report is produced for each basin that contains a Verified List of impaired waters. 

The report also provides an updated and more thorough evaluation of water quality, 

associated biological resources, and current management plans. The Department will 

adopt the Verified List by the Department through a Secretarial Order and submit it 

to the EPA as the State’s Section 303(d) list of impaired waters. 

• Phase 3: Development and Adoption of TMDLs. TMDLs for priority impaired 

waters in the basin will be developed and adopted by rule. Because TMDLs cannot 

be developed for all listed waters during a single watershed management cycle due to 

fiscal and technical limitations, waterbodies will be prioritized using the criteria in the 

Identification of Impaired Surface Waters Rule, Rule 62-303, F.A.C. 

• Phase 4: Development of Basin Management Action Plan. A Basin Management 

Action Plan will be developed for each basin that specifies how pollutant loadings 

from point and nonpoint sources of pollution will be allocated and reduced, in order 

to meet TMDL requirements. The plans will include regulatory and nonregulatory 

(e.g., voluntary), structural and nonstructural strategies, and existing management 

plans will be used where feasible. The involvement and support of affected 

stakeholders in this phase will be especially critical. 

• Phase 5: Implementation of Basin Management Action Plan. Implementation of 

the activities specified in the Basin Management Action Plan will begin. This 

includes carrying out rule development as needed, securing funding, informing 

stakeholders and the public, and monitoring and evaluating the implementation of the 

plan. 

To implement the watershed cycle, the State’s river basins have been divided into five 

groups within each of the Department’s six districts statewide, and each district will 

assess one basin each year. Table A.1 shows the basin groups for implementing the 

cycle in the Department’s districts, and Figure A.1 shows these groups and the rotating 

cycle in the districts. Table A.2, which lists the basin rotation schedule for TMDL


development and implementation, shows that it will take nine years to complete one full 

cycle of the State. 

The watershed management cycle is an iterative, or repeated, process. One of its key 

components is that the effectiveness of management activities (TMDL implementation) 

will be monitored in successive cycles. Monitoring conducted in Phase 2 of subsequent 

cycles will be targeted at evaluating whether water quality objectives are being met and 

whether individual waters are no longer impaired. The Department also will track the 

implementation of scheduled restoration activities, whether required or voluntary, to 

ensure continued progress towards meeting the TMDLs.

Pollutants can enter a waterbody through point source discharges (generally from a 

specific facility) or nonpoint discharges (e.g., stormwater runoff, septic tanks). 

Government agencies, businesses, organizations, and individuals who contribute to these 

discharges will be asked to share the responsibility of attaining TMDLs through load 

allocations (the amount of a specified pollutant allotted for discharge) that are based on 

an established TMDL. Table A.3 summarizes these potentially affected stakeholders, 

and the actions they may be asked to take to help achieve a TMDL. 

Table A.3: Potentially Affected Stakeholders and Actions To Achieve TMDLs 

Potentially Affected Stakeholders 

Municipal stormwater/wastewater programs 

Commercial developers, homebuilders, individual 

homeowners 

Municipal and industrial wastewater treatment 

facilities, NPDES-permitted facilities 

Farming and silviculture operations 

Federal, regional, state agencies; regional and 

local water quality coalitions 

Actions To Achieve TMDL 

Reduce and treat urban stormwater runoff through 

stormwater retrofits, replacement of septic tanks, 

connect to central sewer. 

Improve development design and construction, 

enhance best management practices, replace septic 

tanks, connect to central sewer. 

Reduce pollutant loadings from permitted 

discharges 

Reduce and treat runoff through best management 

practices 

Carry out waterbody restoration projects and public 

works projects.

Appendix B: Supplementary Ecological Information in the 


Evaluation of Ecological Resources 

This appendix summarizes and discusses ecologically important resources and 

problems in the Ocklawaha Basin. Aquatic and wetland habitats and species are 

emphasized because these are most affected by declines in water quality. Table B.1 

summarizes documented information about important ecological resources by planning 

unit. Information for the table was compiled from Geographic Information System 

databases prepared by the Department (Outstanding Florida Waters [OFW] and Aquatic 

Preserves), the Florida Natural Areas Inventory (FNAI) (listed plant and animal species), 

and the Florida Fish and Wildlife Conservation Commission (FWC). Supplemental data 

for rare and imperiled fish occurrences were obtained from the FWC Freshwater Fishes 

of Florida Database (2001).

Natural Communities 

Land cover maps were used to identify major natural communities in the basin. The 

maps identified 22 different land cover classifications: 17 classes of natural vegetation, 1 

aquatic class, and 4 classes of disturbed land. Mapping was based on LandSat imagery 

taken from 1985 to 1989 and is not intended to be an accurate portrayal of current land 

use. The maps do provide a relative picture of the type and spatial importance of natural 

communities in the Ocklawaha Basin, and overall this mapping appears to have an 

accuracy of 80 to 90 percent (Cox et al., 1994).


NOTEWORHTY: LAND USE MAPPING 

Land use data used to identify natural communities were mapped by the Florida Fish and Wildlife 

Conservation Commission from LandSat imagery taken from 1985 to 1989. Land use data 

presented in this report were mapped by the SJRWMD, SFWMD, and Suwannee River Water 

Management District (SRWMD) from color infrared photography taken between late 1993 and 

1995. The total acreage and percent of basin acreage for different land covers obtained from 

LandSat imagery will differ from the values obtained for land use interpreted from aerial 

photography for a number of reasons. Besides the difference in dates of mapping, different land 

cover classification schemes were used and the LandSat imagery had less spatial resolution of 

detail than the aerial photography. 

Table B.2 describes each community type and lists the estimated acreage and 

percentage of basin area occupied by each. Disturbed community types predominate, 

covering about 790,000 acres of the basin. Of these, grassland and agricultural land 

occupy the largest area (341,932 acres), followed by shrub and brushland (about 262,121 

acres), and barren land (186,564 acres). Shrub and brushland includes lands that are 

disturbed as part of the harvesting of commercial pine plantations. The greatest 

concentrations of disturbed land occur in the southern half of the Florida Ridge (west of 

Ocala) and around Lake Apopka and the Upper Ocklawaha Chain of Lakes. 

A number of different natural communities occupy the remaining 738,000 acres of 

the basin. Predominant upland types are pinelands, hardwood hammock, sand pine scrub, 

and sandhill. Scrub and sandhill communities in the basin are some of the best remaining 

examples of this habitat type in Florida, although they are threatened by expanding urban 

development (Cox et al., 1994). They are located on sandy soils and generally associated 

with areas of high to moderate aquifer recharge. Areas of the basin where there are still 

substantial tracts of sandhill include the western Florida Ridge, although a large part of 

that area has been converted to either grassland or agricultural land, and north of Rodman 

Reservoir. 

Scrub habitat is found on sand dunes or sandbars that were once part of ancient 

shorelines, which in the basin include areas such as the Mount Dora and Lake Wales 

ridges. Scrub communities are largely endemic or unique to Florida and provide habitat 

for some of the basin’s rarest species. 

Much of the sand pine scrub is near or within the boundaries of the Ocala National 

Forest. Part of that total scrub acreage is planted sand pine (pine plantation) as 

determined from 1995 land use maps. Xeric (Definition: Pertaining to, or adapted to, a 

dry environment) oak scrub includes sites in the Ocala National Forest that have been 

clear-cut and are sometimes dominated during the first one to five years by the xeric oak 

scrub association. 

Wetland, stream, and lake habitats are important components of the basin’s natural 

communities and occupy better than 20 percent of its total area. Major wetland 

communities include hardwood swamp, freshwater marsh, and cypress swamp.

Community Description 

UPLANDS 

Dry prairie 1,591 0.09 

Large native grass and shrub communities located on flat 

terrain intermixed with cypress swamps, bayheads, 

freshwater marshes, and hardwood hammocks. 

Palmetto prairies, which are pine flatwoods where the 

overstory has been removed, are included in this class. 

Pinelands 253,308 14.25 

Pinelands occur on flat sandy terrain. Dominant 

overstory trees are longleaf pine, slash pine, or pond 

pine, and includes pine plantations. Fire is a major 

source of natural disturbance. Dominance by longleaf 

pine occurs on drier well drained sites. Pond pine occur 

on poorly drained sites and slash pond occur on 

intermediate or moderately wet sites. 

Sand pine scrub 71,654 4.03 

Sand pine scrub is a very dry community occurring on 

extremely well-drained sterile sands deposited along 

ridges or former dunes. Community is dominated by an 

overstory of sand pine with an understory of myrtle oak, 

Chapman's oak, sand liveoak, and scrub holly. Ground 

cover is usually sparse. Fire is an important 

management tool that results in even-aged stands within 

regenerated sites. 

Sandhill 99,533 5.60 

Sandhill communities occur on rolling terrain with deep, 

well drained, dry sand soils. Overstory is dominated by 

longleaf pine with an understory of turkey oak and 

bluejack oak. Fire is important for the control of 

hardwood species and continued generation of the 

sandhill community. 

Xeric oak scrub 21,450 1.21 

This community occurs in areas of deep sands. It 

comprises clumped patches of low growing xeric oak 

species. Included are clearcut sites within the Ocala 

National Forest that during the first five years of regrowth 

are dominated by xeric oaks. Common species are 

myrtle oak, scrub plum, sand liveoak, Chapman’s oak, 

and saw palmetto. Fire is an important factor in 

maintaining oak scrub. 

This community contains a relatively equal mix of 

Mixed pinehardwood

WETLANDS and OPEN WATER 

These communities are dominated by herbaceous plant 

species growing on sand, clay, marl, or organic soils. 

Common species are pickerel weed, spatterdock, cattail, 

and sawgrass. Water depths and inundation regimes 

vary. Generally, freshwater marshes occur in deeper 

areas that are inundated longer and are characterized by 

Freshwater marsh 

tall emergents and floating-leafed species. This category 

84,585 4.76 

and Wet prairie 

also includes portions of freshwater lakes, rivers, and 

canals that are dominated by floating-leafed plants. Wet 

prairies commonly occur in shallow, periodically 

inundated areas or are found in scattered shallow 

depressions within dry prairies. They are usually 

dominated by aquatic grasses, sedges, and their 

associates. 

Dominant overstory tree is either pond or bald cypress. 

Cypress swamp 48,581 2.73 Found along borders of large rivers, creeks and lakes or 

as isolated depressions. 

These swamps occur as either stands of hardwoods or a 

mix of hardwoods and cypress. Overstory tree species 

are black gum, water tupelo, bald cypress, dahoon holly, 

Mixed hardwood 

53,142 2.99 cabbage palm, red maple, or sweetbay. Commonly 

swamp 

found on organic soils along floodplains of non-alluvial 

rivers, creeks and lakes. 

DISTURBED LANDS 

Upland communities of very low-growing grasses and 

forbs. Usually found on intensively managed sites such 

as improved pastures, lawns, golf courses, road 

Grassland / 

shoulders, cemeteries, or weedy, fallow agricultural 

341,932 19.24 

agricultural land 

fields. This early successional category includes all sites 

with herbaceous vegetation between the stages of bare 

ground and shrub and brush, as well as all agricultural 

fields. 

The shrub and brush includes natural upland 

communities that have been recently disturbed (such as 

clear-cutting commercial pinelands, land clearing, or fire) 

Shrub and brush 

262,121 14.75 and are recovering through natural successional 

land 

processes. It is characterized as an early stage of 

succession for old fields, dominated by various shrubs, 

tree saplings, and lesser amounts of grasses and herbs. 

Highly reflective areas including roads, beaches, strip 

mines, tilled agricultural sites, and cleared land are 

Barren land 186,564 10.5 included as barren land. Unvegetated urban areas are 

also included. Vegetated tracts within urban areas are 

mapped by their predominate vegetative cover.


Ecoregions 

In general, ecoregions are delineated by patterns of homogeneity in a combination of 

factors such as climate, physiography, geology, soils, and vegetation. They were refined 

in Florida for application to aquatic ecosystems for use as an assessment and 

management tool. The Ocklawaha Basin is located predominately in the Southern 

Coastal Plain Ecoregion, also referred to as Ecoregion 75 (Griffith et al., 1994). 

Ecoregions are further delineated into smaller subecoregions with specific delineation 

schemes for both lakes and streams. Stream and lake subecoregions are not intended to 

characterize the water quality of a specific lake, but rather define the expected biological 

potential of benthic (Definition: Occurring at the bottom of a body of water) 

macroinvertebrate communities for a given set of environmental characteristics. 

Stream Subecoregions 

Streams in the Ocklawaha Basin occupy 3 of the 13 subregions delineated for Florida 

based on physical, chemical, and biological characteristics (Figure B.1). These 

subregions are the Central Florida Ridges and Uplands, Eastern Florida Flatwoods, and 

Southwestern Florida Flatwoods. The Central Florida Ridges and Uplands are generally 

characterized by typically flat plains with sandy highlands and ridges and are commonly 

vegetated by longleaf pine and xerophytic oaks. Acidic and well-drained soil types 

underlie this subregion. The Eastern Florida Flatwoods and Southwestern Florida 

Flatwoods are flat plains with 10 to 50 percent coverage by standing water. Expected 

natural vegetation is pine flatwoods and grassland and for the Eastern Flatwoods only, 

freshwater marshes and swamp associations.


Figure B.1: Delineation of Stream Subecoregions


Lake Ecoregions 

In 1997, Florida was divided into 47 lake ecoregions based on differences in soil and 

sediment types, lake origins, hydrology, and water chemistry (Griffith et al., 1997). This 

basin contains 16 of the 47 lake ecoregions. In 2000, a biological classification scheme 

was proposed which identified lake classes based on benthic macroinvertebrate biota. 

This classification scheme reconciled with the previous classification based on water 

chemistry and geographic consideration (Gerritsen et al., 2000). 

Using this information, five distinct lake types were identified statewide that help to 

distinguish further the expected biological condition of a lake. Four of these types are 

found in the Ocklawaha Basin: acid/colored, alkaline/colored, alkaline/clear, and 

acid/clear in Ecoregion 75. Acid/colored lakes are generally low in nutrients and biologic 

productivity. By comparison, alkaline/colored lakes have higher nutrient levels and 

biological productivity. The lakes with the highest levels of nutrients and biological 

productivity are alkaline/clear. Examples are Lake Apopka and the lakes in the Upper 

Ocklawaha Chain of Lakes. Lakes with the lowest levels of nutrients and least biological 

productivity are acid/clear lakes on sandy soils in Ecoregion 75. Many of these are found 

on ridges and uplands. 

Rare and Protected Plant and Animal Species 

The Ocklawaha Basin supports a large and diverse number of plant and animal 

species. Between 100 and 125 species of aquatic insects and more than 410 species of 

vertebrates, including at least 110 fish species, have been identified in the basin. The 

Ocklawaha River’s floodplain forest and the Ocala National Forest (just to the east of the 

river) provide excellent habitat for the Florida black bear. The basin also provides 

excellent habitat for numerous game species, including gray and fox squirrels and whitetailed 

deer. 

There are 31 animal species and 39 plant species in the Basin which have been listed 

as endangered, threatened or a species of special concern under state and/or federal law. 

Tables B.3 and B.4 contain listed species occurring in the Ocklawaha Basin. 

The Orange Creek Basin is one of the five most important nesting areas for bald 

eagles and also a prominent nesting area for osprey. The marshy River Styx area around 

Orange Lake is home to a wood stork rookery that has been documented for at least 80 

years. Wood storks are listed as endangered at both state and federal levels. The 

shortnose sturgeon is currently limited to the lower St. Johns River, but historically may 

have used the Ocklawaha River for spawning before the construction of the Kirkpatrick 

Dam. 

At one time, the Basin may have provided habitat for several currently listed animals. 

The Florida panther’s historic range is believed to have included the Ocklawaha River 

corridor. Similarly, the historic range of the Florida Everglades kite included the river 

corridor near Lake Griffin, and the West Indian manatee also used the river. 

Construction of the Kirkpatrick Dam, however, has prevented manatees from accessing 

warm water refugia in the Basin’s springs.

may be rare in parts of range. 

G5 or S5 – Demonstrably secure globally or in Florida. 

G#G# or S#S# - Range of rank, because insufficient data 

to assign specific rank. 

G# or S# – Tentative rank 

G#T# or S#T# - Rank of a taxonomic subgroup such as a 

subspecies or variety. G or S portion of rank refers to the 

entire species and the T portion refers to the specific 

subgroup rank. 

G#Q or S#Q – Rank of questionable species, confusion 

over whether it is a species or subspecies. 

G#T#Q – Rank of questionable subspecies, because 

validity of subspecies is questioned. 

Several fish species, with documented occurrences in the Basin, are considered rare 

or imperiled (Hoehn, 1998). They include species with populations in decline and those 

which are vulnerable because of restricted range or habitat preference. The Nature 

Conservancy has identified the Ocklawaha Basin as a critical watershed for conservation 

of at-risk fish species (Master et al., 1998). The rare and imperiled blackbanded sunfish, 

bluenose shiner, river goby, Lake Eustis pupfish, and tessellated darter have been 

collected in different parts of the Basin. The bluenose shiner, Lake Eustis pupfish, and 

tessellated darter are also classified by the Florida Fish and Wildlife Conservation 

Commission (FWC) as species of special concern. The bluenose shiner occurs in the St. 

Johns River. The Ocklawaha River and St. Johns River populations of these fish is 

disjunct from Panhandle populations (Gilbert, 1992). The tessellated darter is endemic to 

the Ocklawaha Basin. 

Numerous other animal species reach the southern limit of their geographic range in 

the Ocklawaha Basin or are unique members of the Basin’s natural communities. 

Compared to other river basins in Florida, a relatively high proportion (17%) of the 

reptile species here are endemic, or nearly so. Some examples of species reaching their 

southern limits are the tiger salamander, river swamp frog, striped newt, and flatwoods 

salamander (a listed species). One fish species, the brown darter, is found only in the 

Ocklawaha Basin and the St. Johns River near the town of Welaka (at the mouth of the 

Ocklawaha River). Two macroinvertebrates, Campoloma floridensis, a live bearing snail, 

and Procambarus geodytes, a crayfish, are endemic to the St. Johns River drainage 

system (Florida Defenders of the Environment, March 1970).


NOTEWORHTY: SPECIES RANKING 

In addition to state and federal rankings, the Florida Natural Areas Inventory (FNAI) determines a 

species’ global and state rank based on its status. Status is based on factors such as estimated 

abundance, range, adequacy of protection, ecological fragility (vulnerability), and threat of 

extinction. Several animal species occur in the basin that are not protected species, but have 

FNAI rankings indicating that they are imperiled or rare in Florida or very local in range (rankings 

of S2 and S3). These include the black crowned night heron, yellow crowned night heron, glossy 

ibis, big brown bat, Bachman’s sparrow, striped newt, and Florida scrub lizard. 

The basin contains many unique and rare botanical specimens as well, some of which 

are listed species. The prominence of sandy ridges and scrub habitat supports these 

species. The scrub lupine and scrub palm are good examples. The cedar elm has been 

recorded here, while the next known concentration of this species in Florida is in the 

Suwannee Basin. FNAI ranks the cedar elm as critically imperiled in Florida (rank of 

S1), but it is not a protected species. Several other plant species in the basin that are 

ranked by FNAI as very critically or critically imperiled in Florida (ranks of S1 and S2) 

include Wagner’s spleenwort, Curtiss’ spleenwort, scrub leatherwood, and Texas 

anemone. 

State and federally protected plant and animal species are found in all the planning 

units. Threatened and endangered species tend to have more specific habitat 

requirements and less tolerance for disturbance and adverse impacts to their 

environments than other species. For these reasons, listed species occurrences can be 

used as a general index of biological integrity (Allen, 1986). Documented numbers of 

occurrences of listed species are greatest in the planning units at the northern end of the 

basin (Orange Creek, 137; Florida Ridge, 92; and Rodman Reservoir, 94) compared with 

the southern end (Palatlakaha River and Lake Apopka, 35 each). 

Rare and imperiled fish have been found in six planning units. These are lake and 

stream fish that met one or more of the following criteria as listed in Hoehn (1998): 

(1) Listed as endangered, threatened, or species of special concern by FWC; (2) Ranked 

by the Florida Committee on Rare and Endangered Plants and Animals (FCREPA) 

(Gilbert, 1992); (3) Ranked by FNAI as G1/S1, G2/S2, or G3/S3; and (4) Assigned a 

biological score greater than or equal to 24 by Millsap et al. (1990). Generally, these 

species represent declining populations in need of management actions or populations 

that are vulnerable because of limited or restricted range, habitat preference, or isolation. 

A rarity ranking was applied to stream segments based on the average ranking of stream 

fish by the FNAI and FCREPA. Rarity rankings for the Ocklawaha Basin ranged from 

medium-low to medium. 

Basinwide data and nesting trends for different bird groups show different results. 

Basinwide, 97 bald eagle (Haliaeetus leucocephalus) nests were active during surveys in 

1999—a substantially higher number than the 72 observed in 1995. The trend since 1995 

has been an increase in number of nests. Eagles are a federally threatened species that 

feeds primarily on fish but also consumes birds, smaller mammals, and carrion. They 

represent the upper trophic levels of the aquatic food chain, making them susceptible to 

bioaccumulation and biomagnification effects of contaminants.


The number of active wading bird rookeries found in surveys by the FWC decreased 

from 28 in the 1970s to 20 in 1999. Factors in this change were the dry conditions and 

low water levels during the 1999 survey. Many long established rookeries were not in 

use because of less-than-favorable environmental conditions. Wading bird rookeries are 

composed primarily of herons, egrets, wood storks, ibis, and cattle egrets. Except for 

cattle egrets, wading birds feed on aquatic organisms, including fish, and depend on 

wetlands, lakes, and streams for habitat. 

Large numbers of unique species of invertebrates are associated with ground water 

habitats, including aquatic caves, springs, and sinkhole systems (Table B.5). Most 

species are ranked as very critically to critically imperiled by the FNAI but do not have 

protected species status. The one exception is the federally threatened Squirrel Chimney 

Cave shrimp (Palaemonetes cummingi Chace), found only in Squirrel Chimney Cave in 

Alachua County. 

Three fish species (catfish, tilapia, and gizzard shad [Dorosoma cepedianum]) are 

harvested commercially and contribute to the basin’s economy. From 1993 through 

1999, annual catches averaged 356,806 pounds for catfish, 14,695 pounds for tilapia, and 

1,015,960 pounds for gizzard shad. The annual average economic value of these fish 

using an economic market factor of 1.82 is $326,451 for catfish, $30,703 for tilapia, and 

$314,338 for gizzard shad (Crumpton, October, 2000, personal communication). Gizzard 

shad have been harvested from Lake Apopka since 1993 to supplement other activities 

that reduce phosphorus loads in the lake (SJRWMD, 2001).

Appendix C: Information on Reasonable Assurance

SUBJECT: 

Guidance for Development of Documentation To Provide Reasonable 

Assurance that Proposed Pollution Control Mechanisms Will Result in the 

Restoration of Designated Uses in Impaired Waters 

The purpose of this memo is to describe the types of information that should be 

considered, and subsequently documented, when evaluating whether there is sufficient 

reasonable assurance that: 

1) Proposed pollution control mechanisms (typically described in watershed 

management or restoration plans) addressing impaired waters will result in the 

attainment of applicable water quality standards (designated uses) at a clearly defined 

point in the future, and 

2) Reasonable progress towards restoration of designated uses will be made by the time 

the next 303(d) list of impaired waters is due to be submitted to the EPA. 

There are many site-specific issues related to determining whether reasonable 

assurance has been provided. Accordingly, this document describes the elements or 

issues that should be considered when evaluating a submittal or when documenting the 

basis for the Department’s decision, rather than attempting to establish specific criteria on 

what constitutes reasonable assurance. 

It should be noted that the term “reasonable assurance” is used throughout many 

Department programs and rules, and this guidance specifically addresses the issues 

related to the “reasonable assurance” provided by proposed pollution control 

mechanisms. This guidance should not be used to evaluate the meaning of reasonable 

assurance in other contexts, particularly in permitting decisions. 

Background 

The Impaired Surface Waters Rule (IWR), Rule 62-303, F.A.C. (Identification of 

Impaired Surface Waters), establishes a formal mechanism for identifying surface waters 

in Florida that are impaired (do not meet applicable water quality standards) by 

pollutants. Most waters that are verified as being impaired by a pollutant will be listed on 

the State’s 303(d) list pursuant to the Florida Watershed Restoration Act (FWRA) and 

Section 303(d) of the Clean Water Act. Once listed, Total Maximum Daily Loads 

(TMDLs) will be developed for the pollutants causing the impairment of the listed


waters. However, as required by the FWRA, the Department will evaluate whether 

existing or proposed pollution control mechanisms will effectively address the 

impairment before placing a water on the State’s Verified List. If the Department can 

document there is reasonable assurance that the impairment will be effectively addressed 

by the control measure, then the water will not be listed on the final Verified List (other 

impaired waters that will not be listed include waters with TMDLs and waters impaired 

by pollution). 

Current Rule Text Relating to Evaluation of Pollution Control Mechanisms 

The rule text addressing the evaluation of proposed pollution control mechanisms is 

as follows: 

Rule 62-303.600, Evaluation of Pollution Control Mechanisms 

1) Upon determining that a waterbody is impaired, the Department shall evaluate 

whether existing or proposed technology-based effluent limitations and other 

pollution control programs under local, state, or federal authority are sufficient to 

result in the attainment of applicable water quality standards. 

2) If, as a result of the factors set forth in (1), the waterbody segment is expected to 

attain water quality standards in the future and is expected to make reasonable 

progress towards attainment of water quality standards by the time the next 303(d) list 

is scheduled to be submitted to EPA, the segment shall not be listed on the Verified 

List. The Department shall document the basis for its decision, noting any proposed 

pollution control mechanisms and expected improvements in water quality that 

provide reasonable assurance that the waterbody segment will attain applicable water 

quality standards. 

Responsible Parties for Reasonable Assurance Demonstration 

It is ultimately the Department’s responsibility to assure adequate documentation in 

the administrative record whenever the Department decides to not list an impaired 

waterbody segment for a given pollutant. This documentation will be very important 

because the Verified Lists will be adopted by Order of the Secretary and third parties will 

be provided an opportunity to challenge, via an administrative hearing, all listing 

decisions (both those listing a water and those to not list a water for a given pollutant). 

However, the Department expects that local stakeholders will often offer to prepare the 

necessary documentation to demonstrate reasonable assurance that proposed control 

mechanisms will restore a given waterbody. The Department will provide guidance to 

stakeholders on what information is needed and how it should be submitted. 

Time Frame for Development of Documentation 

The Department plans to prepare basin-specific Verified Lists as part of its watershed 

management cycle, which rotates through all of the State’s basins over a five-year, five-


phased cycle 1 . During the first phase of the cycle, the Department will assess water 

quality in the basin and prepare a draft Planning List of potentially impaired waters. The 

Department and interested parties will then have approximately one year (Phase 2) to 

monitor waters on the planning list and prepare documentation, as appropriate, to provide 

reasonable assurance that impaired waters will be restored. The Department will review 

submittals from interested parties during Phase 2, before adopting the Verified List for 

the basin containing the waterbody segment in question. 

What It Means To Be Under Local, State, or Federal Authority 

Both the FWRA and the IWR require that the pollution control programs under 

consideration be “under local, state, or federal authority.” A pollution control program 

will be considered “under local, state, or federal authority” if the program is subject to or 

required by a local ordinance, state statute or rule, or federal statute or regulation. 

Programs will also be considered under local, state, or federal authority if they are 

subject to a written agreement, signed by both local stakeholders and at least one 

governmental entity, that includes measurable goals, performance criteria, benchmarks, 

and back-up corrective actions to assure the further progress of the program. It is 

important to note that these written agreements do not need to be enforceable for 

nonregulated nonpoint sources. 

Many nonpoint sources are currently outside of the regulatory programs of EPA, the 

Department, and the water management districts, and reductions at these nonpoint 

sources will be voluntary. In fact, pollution control mechanisms for these nonpoint 

sources would be voluntary even if a TMDL were developed. As such, these agreements 

may provide the same level of reasonable assurance that can be provided for a TMDL 

implementation plan as long as they maintain the Department’s enforcement capability 

over all point sources involved. 

Time Frame for Attaining Water Quality Standards 

The FWRA and the IWR do not establish a specific time limit by which waters must 

attain applicable water quality standards or designated uses. However, the pollution 

control mechanisms or watershed restoration plan must provide reasonable assurance that 

designated uses will be met at some time in the future. As such, the documentation 

submitted to the Department must provide a specific date by which time designated uses 

are expected to be restored. In cases where designated uses will not be met for many 

years, the documentation should also provide justification as to why the specified time is 

needed to restore designated uses. 

Parameter-Specific Nature of Demonstration 

For the Department not to place an impaired waterbody segment on the Verified List, 

reasonable assurance must be provided for each pollutant that has been documented to be 

causing impairment of the waterbody segment. However, some entities, including the 

Department, may want to provide reasonable assurance addressing only selected 

1 Federal regulations currently call for state 303(d) lists every two years, but Florida plans to submit annual updates 

based on the basin-specific Verified Lists.


pollutants, which could result in the Department not listing the waterbody segment for 

those pollutants, but still listing it for others. In this event, TMDLs will only be 

developed for the remaining listed pollutants. 

Information To Consider and Document when Assessing Reasonable 

Assurance in the IWR 

To provide reasonable assurance that existing or proposed pollution control 

mechanisms will restore designated uses, the following information should be evaluated 

and documented for the Administrative Record: 

1) A Description of the Impaired Water—name of the water listed on the Verified 

List, the location of the waterbody and watershed, the watershed/8-digit cataloging 

unit code, the NHD identifier (when they become available), the type (lake, stream, or 

estuary) of water, the water use classification, the designated use not being attained, 

the length (miles) or area (acres) of impaired area, the pollutant(s) of concern (those 

identified as causing or contributing to the impairment), and the suspected or 

documented source(s) of the pollutant(s) of concern. 

2) A Description of the Water Quality or Aquatic Ecological Goals—a description of 

the water quality–based targets or aquatic ecological goals (both interim and final) 

that have been established for the pollutant(s) of concern, the averaging period for 

any numeric water quality goals, a discussion of how these goals will result in the 

restoration of the waterbody’s impaired designated uses, a schedule indicating when 

interim and final targets are expected to be met, and a description of procedures (with 

thresholds) to determine whether additional (backup) corrective actions are needed. 

3) A Description of the Proposed Management Actions To Be Undertaken—names 

of the responsible participating entities (government, private, others), a summary and 

list of existing or proposed management activities designed to restore water quality, 

the geographic scope of any proposed management activities, documentation of the 

estimated pollutant load reduction and other benefits anticipated from implementation 

of individual management actions, copies of written agreements committing 

participants to the management actions, a discussion on how future growth and new 

sources will be addressed, confirmed sources of funding, an implementation schedule 

(including interim milestones and the date by which designated uses will be restored), 

and any enforcement programs or local ordinances, if the management strategy is not 

voluntary. 

4) A Description of Procedures for Monitoring and Reporting Results—a 

description of the water quality monitoring program to be implemented (including 

station locations, parameters sampled, and sampling frequencies) to demonstrate 

reasonable progress; quality assurance/quality control elements that demonstrate the 

monitoring will comply with Rule 62-160, F.A.C.; procedures for entering all 

appropriate data into STORET; the responsible monitoring and reporting entity; the


frequency and format for reporting results; the frequency and format for reporting on 

the implementation of all proposed management activities; and methods for 

evaluating progress towards goals. 

5) A Description of Proposed Corrective Actions—a description of proposed 

corrective actions (and any supporting document[s]) that will be undertaken if water 

quality does not improve after implementation of the management actions or if 

management actions are not completed on schedule, and a process for notifying the 

Department that these corrective actions are being implemented. 

Water Quality–Based Targets and Aquatic Ecological Goals 

Some of the most important elements listed above are the requirements to provide 

water quality–based targets or aquatic ecological goals and a discussion on how resultant 

pollutant(s) reduction targets/goals will result in restoration of designated uses. Some 

people have expressed concern about these targets because they equate a water 

quality–based restoration target with a TMDL (thus assuming a “Catch 22” that a TMDL 

is needed to make a demonstration that a TMDL is not needed). However, as is also the 

case for TMDLs, water quality–based targets can take many forms, and need not be a 

result of a complex hydrodynamic/water quality model. 

In some cases, there may be sufficient historical data (paleolimnological data, 

loadings from periods predating the impairment, or baseline data for Outstanding Florida 

Waters 2 , for example) that could be used to determine an appropriate water quality target. 

In other cases, simplified modeling (including regression analysis) may allow for 

conservative estimates of the assimilative capacity that could then be used as the basis for 

restoration goals. And, finally, a water quality target may have been developed that 

would be scientifically equivalent to (or act as the basis for) a TMDL, but the target has 

not been administratively adopted as a TMDL. In each of these cases, a sound water 

quality target could be used to evaluate whether the proposed pollution control 

mechanisms will sufficiently reduce loadings to meet the assimilative capacity of the 

water in question and result in attainment of designated uses. 

Interim Targets 

Because it will usually take many years to restore fully the designated uses of an 

impaired water, interim water quality targets will often be needed to measure whether 

reasonable progress is being made towards the restoration of designated uses. Examples 

of such interim targets are provided in the last section of this document, but site-specific 

measures are also encouraged. 

Averaging Periods for Water Quality Targets 

While the averaging period for water quality–based targets should be consistent with 

how the underlying standard is expressed, they can often be expressed in a variety of 

ways and need not be expressed as “daily loads.” Annual averages or medians are often 

appropriate for some parameters, but shorter-term (seasonal, for example) averages may 

2 Baseline data would be data for the year prior to designation of the OFW.


be necessary if the impairment is limited to specific seasons or parts of the year. Multiyear 

averages may be appropriate in limited circumstances where there is naturally high 

variation of the water quality target. 

Estimates of Pollutant Reductions from Restoration Actions 

It will often be difficult to estimate precisely the pollutant reductions that will result 

from specific restoration activities. This is particularly true for the implementation of 

best management practices (BMPs). However, to provide reasonable assurance that a 

BMP or other restoration action will reduce loadings of the pollutant of concern to a level 

that will restore the water’s designated uses, documentation should address how the 

reductions were calculated, including providing documented values from the scientific 

literature for reductions attributed to similar management actions. If the expected 

reductions are expressed as a range, the midpoint of the range should be used as the basis 

for estimating reductions, unless documentation is provided supporting the use of 

different removal efficiencies in this specific application. 

New Sources/Growth 

Another key element is the discussion on how future growth and new sources will be 

addressed. Restoration goals must address possible increased loadings of the pollutant of 

concern that are anticipated due to population growth or land use changes in contributing 

watersheds, both from point and nonpoint sources. This will be particularly important for 

waters impaired by nutrients, given that so many Florida watersheds are faced with 

continuing urban, residential, and agricultural development that results in increased 

nutrient loading from stormwater, septic tanks, and wastewater discharges. 

Examples of Reasonable Progress 

The determination of whether there will be reasonable progress towards attainment of 

water quality standards will be very site- and pollutant-specific. Documentation should 

be provided supporting specific progress towards restoration of the designated uses of the 

impaired water. Possible examples of reasonable progress include, but are not limited to 

the following: 

A written commitment to implement controls reducing loadings within a specified 

time frame from watershed stakeholders representing at least 50 percent of the 

anthropogenic load of the pollutant(s) of concern; 

Evidence of at least a 10 percent reduction (or alternatively, a percent reduction 

consistent with meeting the water quality target by the specified date) in annual 

anthropogenic loading of the pollutant(s) of concern; 

Evidence of at least a 10 percent decrease (or alternatively, a percent decrease 

consistent with meeting the water quality target by the specified date) in the annual 

average concentration of the pollutant(s) of concern in the water;


Bioassessment results showing there has been an improvement in the health of the 

biological community of the water, as measured by bioassessment procedures similar 

to those used to determine impairment and conducted in similar conditions; or 

Adoption of a local ordinance that specifically provides water quality goals, restricts 

growth or loads tied to the pollutant(s) of concern, and provides an enforcement 

option if the proposed management measure(s) are not implemented as required. 

Reasonable progress must be made by the time the next 303(d) list is due to be 

submitted to EPA, which is currently every two years. EPA has contemplated changing 

the listing cycle to every four or five years, and the IWR was specifically worded to 

allow a longer time frame for requiring reasonable progress in the event that the listing 

cycle changes. 

Long-Term Requirements 

If at any time the Department determines that reasonable assurance and reasonable 

progress are not being met, the order adopting the Verified List will be amended to 

include the waterbody on the Verified List for the pollutant(s) in question. Additional 

reasonable progress must be made each time a waterbody is considered for listing under 

Rule 62-303, F.A.C. (every five years).

Appendix D: Methodology for Determining Impairment Based 

on the Impaired Surface Waters Rule 

In implementing the watershed management approach, the Department relies on 

environmental data collected by a variety of organizations. Effective project planning, 

sampling design, raw data review, and data analysis are essential to making accurate 

assessments of impairment and to TMDL development and implementation. 

The Identification of Impaired Surface Waters Rule 

To identify impaired waters in each of the State’s river basins, the Department 

evaluates water quality data using the science-based methodology in the Identification of 

Impaired Surface Waters Rule (Rule 62-303, FAC), or IWR. The rule establishes 

specific criteria and thresholds for impairment, in addition to data sufficiency and data 

quality requirements. The methodology described in the rule is based on a statistical 

approach designed to provide a high degree of confidence that the outcome of 

assessments of impairment accurately describe real conditions. The complete text of the 

IWR is available at http://www.dep.state.fl.us/water/tmdl/docs/AmendedIWR.pdf. 

As part of the watershed management approach, the Department follows the 

methodology in the IWR to develop a Planning List of potentially impaired waters for 

each river basin in the state. The methodology for developing the Planning List includes 

an evaluation of aquatic life use support, primary contact and recreational use support, 

fish and shellfish consumption use support, drinking water use support, and protection of 

human health. The IWR specifies that data older than ten years cannot be used to 

evaluate water quality criteria exceedances for the Planning List. As required by Chapter 

403.067(2), FS, the Planning List is not used to administer or implement any regulatory 

program, and is submitted to the EPA for informational purposes only. 

After further assessment using the methodology in Part III of the IWR (Section 62- 

303.400, FAC), the Department determines if waters on the Planning List are, in fact, 

impaired and if the impairment is caused by a pollutant. These waters are placed on a 

Verified List. The criteria in the IWR for the Verified List are more stringent than those 

for the Planning List. Data no older than five years from the Planning List assessment 

are used to verify impairment. The Verified List is adopted by Secretarial Order and 

forwarded to the EPA for approval as Florida’s Section 303(d) list of impaired waters. 

The Department will develop TMDLs for waters on the adopted Verified List per Chapter 

403.067(4), FS. 

Attainment of Designated Use(s) 

While the designated uses of a given waterbody are established using the surface 

water quality classification system described in Rule 62-302, FAC, it is important to note 

that the EPA uses slightly different terminology in its description of designated uses. 

Because the Department is required to provide use attainment status for both the State’s 

305(b) report and the State’s 303(d) list of impaired waters, the Department uses EPA


terminology when assessing waters for use attainment. The water quality evaluations and 

decision processes for listing impaired waters that are defined in the IWR are based on 

the following designated use attainment categories: 




Drinking Water Use Attainment and Protection of Human Health

classes.

Sources of Data 

The State’s assessment of impairment in each basin includes an analysis of 

quantitative data from a variety of sources, many of which are readily available to the 

public. These readily available sources include the EPA’s legacy and modernized 

STOrage and RETrieval (STORET) Databases, the U.S. Geological Survey (USGS), the 

Department (FDEP), the Florida Department of Health (FDOH), the water management 

districts, county and local governments, and volunteer monitoring groups. The legacy 

STORET Database is a repository of data collected and uploaded by numerous 

organizations through 1999. It houses approximately 60 percent of the data used in this 

assessment of impairment. The legacy STORET Database can be accessed at 

http://www.dep.state.fl.us/water/storet/index.htm. In 2000, the EPA created a 

modernized version of STORET which included new features designed to address data 

Quality Assurance/Quality Control concerns (see the modernized STORET Website at 

www.epa.gov/storet/). Due to continued problems with batch uploading capability, 

modernized STORET currently has limited utility. It houses only about 5 percent of the 

data used in this assessment of impairment. 

Approximately 35 percent of the data used in this assessment were provided to the 

Department from individual organizations which were not able to enter their data into 

STORET due to time constraints or resource limitations. In an effort to consolidate data 

from the various sources used in assessments, the IWR2002 Database was developed by 

the Department. It is used to store and analyze data, and is programmed according to the 

criteria of the IWR, and the planning and verification periods for each assessment group 

(Groups 1 through 5). Table D.2 shows the planning and verification periods for the first 

basin rotation cycle.

Verified List January 1, 1999 – December 31, 2005 

Notes: Typically, a 10-year data record is used for the development of the Planning Lists, and a 7-year record is used for 

the Verified Lists. If necessary, however, the data record for the Verified listing can be extended by up to 6 months to 

complete a monitoring period that will provide sufficient information to make a listing determination. This 6-month 

extension applies to the development of the Impaired Surface Waters Rule 2002 Database. 

Methodology 

To determine the status of surface water quality in individual basins in Florida, three 

categories of data are evaluated; chemistry data, biological data, and fish consumption 

advisories. A description of each category is provided below. 

Aquatic Life Based Attainment 

The IWR follows the principle of independent applicability. A waterbody is placed 

on the Planning List or Verified List for impairment of aquatic life use support based on 

exceedances of any one of four types of water quality indicators (numeric water quality 

criteria, nutrient thresholds, biological thresholds, and toxicity data). 

EXCEEDANCES OF NUMERIC WATER QUALITY CRITERIA 

Only ambient surface water quality stations are included in assessment of impairment. 

Water quality information from point sources or wells is excluded. Monitoring stations 

are classified as being in one of five waterbody types—spring, stream, lake, estuary, or 

blackwater—based on criteria described in the State’s latest 305(b) report. The following 

parameters are included in assessments: 

Metals 

Nutrients 

Conventionals 

Arsenic, aluminum, cadmium, chromium VI, chromium III, 

copper, iron, lead, mercury, nickel, selenium, silver, 

thallium, zinc, and fluoride. 

Chlorophyll a for streams and estuaries, and Trophic State 

Index (TSI) (chlorophyll a, total nitrogen, and total 

phosphorus) for lakes 

Dissolved oxygen (DO), fecal coliforms, total coliforms, 

turbidity and unionized ammonia


Requirements for placing waters on the Group 1 Planning List include a minimum of 

10 temporally independent samples from the period January, 1989 through 

December,1998. Waters are also placed on the Planning List in instances where less than 

10 temporally independent samples from this period were taken but there were 3 or more 

exceedances of water quality criteria, or where there was 1 exceedance of an acute 

toxicity criterion in a three-year span within the period. The screening methodology for 

the Group 1 Verified List requires at least 20 temporally independent samples from the 

period January, 1995 through June 30, 2002 (five years preceding the Planning List 

assessment). An exceedance is defined as an instance where water quality criteria or 

standards are not met, at any time and by any amount. In the case of dissolved oxygen, it 

is implied that the term “exceedance” means the dissolved oxygen criterion is not met, 

rather than exceeded. 

A computerized assessment algorithm, which contains the water quality criteria in 

Rules 62-302, FAC and the IWR, is used to analyze chemical data to determine if a 

waterbody or waterbody segment should be placed on the Planning List or Verified List. 

Software used in data analyses and statistical summaries include Microsoft Excel, 

Microsoft Access, SAS and Systat statistical software, and ArcView GIS applications. 

A waterbody is placed on the Planning List if there is at least 80 percent confidence 

that the actual criterion exceedance rate is greater than or equal to 10 percent. To be 

placed on the Verified List, at least a 90 percent confidence rate is required. 

EXCEEDANCES OF NUTRIENT THRESHOLDS 

The State currently has only a narrative nutrient criterion, which stipulates “In no case 

shall nutrient concentrations of a body of water be altered so as to cause an imbalance in 

natural populations of aquatic flora or fauna”. The IWR provides an interpretation of the 

narrative nutrient criterion. In general, Trophic State Index (TSI) values and annual 

mean chlorophyll a values are the primary means of assessing nutrient impairment. In 

this assessment, TSI calculations include chlorophyll a, total phosphorus and total 

nitrogen data. 

The IWR also considers other information which might indicate imbalances in flora 

or fauna due to nutrient impairment, such as algal blooms, excessive macrophyte growth, 

a decrease in the distribution (either in density or aerial coverage) of seagrasses or other 

submerged aquatic vegetation, changes in algal species richness, and excessive diel 

(daily) oxygen swings. 

An estuarine waterbody or waterbody segment is considered nutrient impaired if 

annual mean chlorophyll a values are greater than 11 µg/L or if annual mean chlorophyll 

a values increase by more than 50 percent over historical values for at least two 

consecutive years. Streams are considered nutrient impaired if the annual mean 

chlorophyll a values are greater than 20 µg/L or if annual mean chlorophyll a values 

increase by more than 50 percent over historical values for at least two consecutive years. 

Lakes with mean color values greater than 40 platinum cobalt units (PCUs) are 

considered nutrient impaired if annual mean TSI values exceed 60. Lakes with mean 

color values less than or equal to 40 PCUs are considered nutrient impaired if annual


mean TSI values exceed 40. A lake is also considered nutrient impaired if there is an 

increase in TSI over the assessment period or if current TSI values are 10 units higher 

than historical values. 

EXCEEDANCES OF BIOLOGICAL THRESHOLDS 

Bioassessments are carried out for streams, lakes, canals, and rivers using the IWR as 

guidance and following the Department’s bioassessment standard operating procedures. 

The purpose for using bioassessment methodology in surface water characterizations is 

that biological components of the environment manifest long-term water quality 

conditions and thus provide a better indication of a waterbody’s true health than discrete 

chemical or physical measurements alone. Similar to water quality criteria, 

bioassessment methods involve the identification of a biological reference condition, 

based on data from unimpaired or least impacted waters in a given region. 

For the Planning and Verified list assessments, reference condition data are used to 

establish expected scores, ranging from best to worst, for various measures of community 

structure and function, such as numbers or percentages of particular species or feeding 

groups. Data on community structure and function from waters of unknown quality in 

the same region as reference waters are compared with the expected scores of metrics to 

evaluate their biological integrity. 

Metrics (e.g., number of taxa, percent Diptera, percent filter feeders) are used 

independently and as an aggregated group called an index. Indices have advantages over 

individual metrics in that they can integrate several related metrics into one score that 

reflects a wider range of biological variables. A number of bioassessment metrics and 

indices exist for assessing populations of plant and animal life, including fish, diatoms 

(e.g., microscopic algae and unicellular plankton), and macroinvertebrates (e.g., insects, 

crayfish, snails, and mussels). 

Only macroinvertebrate data from ambient sites in State surface waters are used in 

bioassessments conducted for the Planning and Verified Lists. The data include sites 

designated as test and background sites for National Pollutant Discharge Elimination 

System (NPDES) fifth-year inspections, but exclude data from effluent outfalls from 

discharging facilities or data from monitoring sites not clearly established to collect 

ambient water quality data. 

NOTEWORTHY DEFINITION: RIPARIAN 

Of, on, or relating to the banks of a natural course of water. 

Data used to develop the Planning and Verified Lists are obtained from the 

Department’s Biological Database (SBIO) and the EPA’s STORET Water Quality 

Database, where it can be substantiated that the data were generated in compliance with 

established Department bioassessment methods. The data from these databases are used 

without regard to the randomness of sample site selection. In the bioassessment analysis 

process, seasons are defined as follows: winter (1/1–3/31), spring (4/1–6/30), summer 

(7/1–9/30), and fall (10/1–12/31). Wet seasons are generally spring and summer, and dry 

seasons are fall and winter, although conditions can vary in the State as a whole.


LAKE CONDITION INDEX 

The scoring of the individual metrics of the Lake Condition Index (LCI), except 

percent Diptera, is performed according to the following formula: 

100(B/A) where A = the 95 percentile of the reference population and B = observed 

value 

For percent Diptera, the following formula is used: 

100 (100-B)/(100-A) where A = the 95 percentile of the reference population and B = 

observed value 

An average LCI score is calculated by averaging the scores of the six metrics in the 

method: total number of taxa; total number of taxa belonging to the orders 

Ephemeroptera, Odonata, and Trichoptera (EOT taxa); percent EOT taxa; Shannon- 

Wiener Diversity Index score; Hulbert Index score; and percent Dipteran individuals. 

LCI calculations are only provided for clear lakes (< 20 platinum cobalt units [PCUs]). 

As macroinvertebrate-based indices have not been shown to assess colored lakes in 

Florida accurately (> 20 PCUs), they have been excluded from bioassessments. A poor 

or very poor rating based on the average score constitutes a failed bioassessment, per the 

IWR. 

STREAM CONDITION INDEX 

A total Stream Condition Index (SCI) score is calculated by adding the scores of the 

seven metrics in the method, e.g., total number of taxa; total number of taxa belonging to 

the orders Ephemeroptera, Plecoptera, and Trichoptera (EPT taxa); percent Chironomid 

taxa; percent dominant taxa; percent Diptera; percent filter feeders; and Florida Index. A 

poor or very poor rating based on the total score constitutes a failed bioassessment, per 

the IWR. 

BIORECON 

To establish an impairment rating based on BioRecon data, three metrics are used: 

the Florida Index score, total number of taxa, and total number of EPT taxa. If all three 

metrics fail to meet thresholds, the water is deemed “impaired”, per the IWR.


BIOLOGICAL INTEGRITY STANDARD 

Quantitative data, generated through the use of Hester-Dendy artificial substrate 

samplers, are used to calculate Shannon-Wiener Diversity Index scores for paired 

background and test sites, as specified in the Biological Integrity Standard of Rule 62- 

302.530(11), FAC. A failure of the standard constitutes an exceedance of water quality 

criteria. 

EVALUATION OF TOXICITY DATA 

Although the IWR describes the use of toxicity data for the assessment of aquatic lifebased 

attainment, no ambient toxicity data have been available for assessment and this 

metric was not used in this assessment. 


The listing of a Class I, II, or III waterbody segment or waterbody in this attainment 

category is based upon meeting one or more of the following conditions: 

The waterbody segment does not meet the applicable water quality criterion for 

bacteriological quality 

The waterbody segment includes a bathing area that was closed by a local health 

department or county government for more than one week or more than once during a 

calendar year based on bacteriological data 

The waterbody segment includes a bathing area for which a local health department 

or county government issued closures, advisories, or warnings totaling twenty-one 

days or more during a calendar year based on bacteriological data 

The waterbody segment includes a bathing area that was closed or had advisories or 

warnings for more than twelve weeks during a calendar year based on previous 

bacteriological data or on derived relationships between bacteria levels and rainfall or 

flow. 


The listing of a waterbody segment or waterbody in this attainment category is based 

upon not meeting the applicable Class II water quality criterion for bacteriological 

quality, or if a fish consumption advisory has been issued. Fish consumption advisories 

are based on the Florida Department of Health’s “limited consumption” or “no 

consumption” advisories for surface waters because of high levels of mercury in fish 

tissue. In addition, Class II waters that had been approved for shellfish harvesting but 

were downgraded to a more restrictive classification are listed as potentially impaired.


Drinking Water Attainment and Protection of Human Health 

The listing of a Class I waterbody segment or waterbody in this attainment category is 

based upon not meeting an applicable Class I water quality criterion for drinking water.


Appendix E: Water Quality Stations and Trends in the 


Information in this appendix was obtained from an inventory of the legacy and 

modernized STORET Databases, as well as data contributed directly to the Department 

by individual data providers, as of October, 2002. Only stations with data from the 

planning and verified periods are included in Table E.1. It should be noted that 

Table E.1 contains all stations and raw data available to the Department for the 

Ocklawaha Basin as October, 2002, however these data were filtered through the 

assessment requirements of the IWR, and a subset which met those requirements were 

actually used in the preparation of this report.

* For the purposes of this table, an observation is defined as one measurement of one parameter in one 

water sample taken at one depth in one station on one day. 

Water Quality Trends in Waters Currently Meeting Standards in the Ocklawaha Basin 

Trend plots of chlorophyll, dissolved oxygen and turbidity data are provided below 

by planning unit for waterbody segments that were shown to meet standards for nutrients, 

dissolved oxygen and/or turbidity during the verification period (1995 through June, 

2002). There were no data of any kind available for assessment of the Florida Ridge 

planning unit, therefore trend plots are not included for it. Though there were 

chlorophyll, dissolved oxygen and turbidity data available for assessment of some 

waterbody segments in the Lake Apopka planning unit, none met standards for nutrients, 

dissolved oxygen or turbidity, therefore trend plots are also not provided for the Lake 

Apopka planning unit.

Appendix G: Land Uses in the Ocklawaha Basin, by Planning 

Unit 

Table G.1 provides land use information for the Ocklawaha Basin, by planning unit. 

The land use classifications used in Table G.1 are based upon the Florida Land Use, Land 

Cover and Forms Classification System (FLUCCS) (FDOT, 1999). FLUCCS is a 

hierarchically- based categorization scheme with 4 different levels, each of which 

contains information of increasing specificity. The 4 levels of FLUCCS are described 

below: 

LEVEL 1 

This class of data is very general in nature. Data can be obtained from remote 

sensing satellite imagery with supplemental information. Level 1 data would normally be 

used for very large areas, statewide or larger, mapped typically at a scale of 1:1,000,000 

or 1:500,000. At these scales, one inch equals 16 miles (one centimeter per ten 

kilometers) and one inch equals eight miles (one centimeter per five kilometers) 

respectively. 

LEVEL 2 

This class of data is more specific than Level 1. Level 2 data are normally obtained 

from high altitude imagery (40,000 to 60,000 feet) supplemented by satellite imagery and 

other materials, such as topographic maps. Mapping typically might be at a scale of 

1:100,000 or one inch equals 8,333 feet (one centimeter per one kilometer). 

LEVEL 3 

This class of data is usually obtained from medium altitude photography flown 

between 10,000 and 40,000 feet. The mapping scale typically is 1:24,000 or one inch 

equals 2,000 feet (one centimeter per 0.24 kilometer). 

LEVEL 4 

This more specific class of data is obtained from low altitude photography flown 

below 10,000 feet. In comparison with the above-mentioned levels, Level 4 typically 

might be mapped at a scale of 1:6,000 or one inch equals 500 feet (one centimeter per 

0.06 kilometer).

Appendix H: Documentation Provided during Public Comment 

Period 

The following is a summary of public comments, and the Department’s responses, on 

Florida’s 2002 Verified List of Impaired Surface Waters, compiled in October, 2002. It 

should be noted that the Department has acted upon many of the comments and questions 

contained in this document. Any resulting changes in our analyses are reflected in the 

remainder of this report as much as possible, however some re-analyses may still be 

ongoing. 

EPA’s Comments 

August 26, 2002 

Daryll Joyner, Program Administrator 

Total Maximum Daily Load Program 

Department of Environmental Protection 

Mail Station 3510 

2600 Blair Stone Road 


Dear Mr. Joyner: 

The Environmental Protection Agency, Region 4 (EPA) has reviewed the Florida 

Department of Environmental Protection’s (FDEP) draft 2002 303(d) list and offers the 

comments listed below. It is our understanding that the 2002 list will be submitted as an 

amendment to the 1998 list for certain waterbodies in Group 1 basins and that all of the 

waterbodies in Groups 2 through 5 will stay on the 1998 list until FDEP submits the 

appropriate amendments. Furthermore, as agreed during our August 14, 2002 meeting in 

Tallahassee, the Group 1 waters on the 1998 list for which FDEP did not have sufficient 

water quality data to meet the verification requirements of the Impaired Waters Rule 

(IWR) will also stay on the list. 

The following comments were developed using the verified and master lists that 

were made available for the public meeting held the morning of August 14, 2002. 

Specific comments are organized by the basins that FDEP now identifies as being in 

Group 1. It is our understanding that Group 1 no longer includes the Alafia, 

Hillsborough, and Manatee Rivers. 

GENERAL COMMENTS 

1. Because FDEP did not propose the draft 303(d) list in a manner subject to review and 

approval by EPA, the supporting information for the 303(d) list that is required by 40 

CFR §130.7 has not been reviewed. While states are not required to include all of


this information for public review, it is required for EPA approval. FDEP must 

include this information in the final submission in order for the 303(d) list 

amendment to be approval. [Acknowledged. No response required.] 

2. Based on the draft master lists, a significant number of waters in Group 1 basins will 

be delisted from the 1998 list. In order for EPA to approve these delistings, FDEP 

must provide good cause justification for each delisting (as described in 40 CFR 

§130.10(d)(7)(iv)). For example, any delistings based on natural conditions must 

include documentation of the scientific bases for determining that natural conditions 

existed when the waterbodies were originally listed. We hope that our agencies will 

work closely prior to the October 1 submittal deadline to reach agreement on what 

constitutes adequate supporting documentation for all of the delistings. 

[Acknowledged. The Department will provide supporting justifications, where 

applicable (see Attachment 1).] 

3. For Group 1 basins, the coliforms listings on the 1998 list appear to have been 

replaced in most cases by both fecal and total coliforms listings on the draft 2002 

master and verified lists. Explanations should be provided in the final 2002 list 

submission for cases where only a fecal or total coliforms listing was included instead 

of both. [Acknowledged. The Department will provide explanations in the Comment 

field, as applicable.] 

4. For a number of waters, FDEP intends to use the allowance provided in 40 CFR 

§130.7(b)(1)(iii) in lieu of including them on the 303(d) list. Adequate 

documentation must be provided in the final submission demonstrating that any 

“other pollution control requirements (e.g., best management practices) required by 

local, state, or federal authority” are stringent enough to meet water quality standards 

in the near future. [Acknowledged. Documentation is provided in Attachments 6 and 

7.] 

OCKLAWAHA BASINS 

1. The 1998 lead listing for Lake Dora (WBID 2831) was not included on either the 

draft 2002 master or verified list. 

RESPONSE: Data are available indicating lead meets water quality criteria. The 

parameter should be delisted. 

2. The 1998 nutrient and unionized ammonia listings for Lake Griffin (WBID 2814) 

were not included on either the draft 2002 master or verified list. 

RESPONSE: Watershed has been sub-divided and these parameters are now 

contained within WBID 2814B, Lake Griffin Outlet.


3. The 1998 mercury (based on fish consumption advisory) listing for Lake Ocklawaha 

(WBID 2740B) was not included on either the draft 2002 master or verified list. 

RESPONSE: This water was on the Planning List for mercury based on the fish 

consumption advisory, but was not placed on the verified list because there were not 

enough data within the last 7.5 years. 

4. The draft master list identified the 1998 nutrients and turbidity listings for Apopka 

Marsh (WBID 2856) as being in category 3b, but these listings were not identified as 

having been included on the planning list per the IWR. [Acknowledged. Moved to 

category 3c.] 

5. The draft master list identified the nutrients and cadmium listings for Blue Springs 

(WBID 2838C) as being in category 3b, but these listings were not identified as 


category 3c.] 

6. The draft master list identified the 1998 nutrients and total suspended solids (TSS) 

listings for Cross Creek (WBID 2754) as being in category 3b, but these listings were 

not identified as having been included on the planning list per the IWR. 

[Acknowledged. Moved to category 3c.] 

7. The draft master list identified the 1998 nutrients, turbidity, coliforms, and iron 

listings for Daisy Creek (WBID 2769) as being in category 3b, but these listings were 

not identified as having been included on the planning list per the IWR. 


8. The draft master list includes the 1998 BOD listing for Haynes Creek Reach (WBID 

2817A), but status information for this listing was not provided. 

RESPONSE: Based upon the median concentration of BOD measurements, elevated 

BOD levels were linked to a dissolved oxygen impairment and a combined Dissolved 

Oxygen/BOD impairment was verified. 

9. The draft master list identified the 1998 nutrients and fecal coliforms for Hogtown 

Creek (WBID 2698) as being in category 3b, but these listings were not identified as 


category 3c.] 

10. The draft master list identified the 1998 nutrients listing for Holiday Springs (WBID 

2838D) as being in category 3b, but it was not identified as having been included on 

the planning list per the IWR. [Acknowledged. Moved to category 3c.] 

11. The draft master list identified the 1998 DO and turbidity listings for the Irrigated 

Farm (WBID 2811) as being in category 3b, but these listings were not identified as



category 3c.] 

12. The draft master list identified the 1998 nutrients listing for Kanapaha Lake (WBID 

2717) as being in category 3a, but it was not identified as having been included on the 

planning list per the IWR. [Acknowledged. Moved to category 3c.] 

13. The draft master list identified the 1998 unionized ammonia listing for the Lake 

Carlton Outlet (WBID 2837) as being in category 3b, but it was not identified as 


category 3c.] 

14. The draft master list identified the 1998 lead listing for the Lake Yale Canal (WBID 

2807) as being in category 3b, but it was not identified as having been included on the 

planning list per the IWR. [Acknowledged. Moved to category 3c.] 

15. The draft master list identified the 1998 fecal and total coliforms listings for 

Ocklawaha River/Sunnyhill (WBID 2740F) as being in category 3b, but these listing 

were not identified as having been included on the planning list per the IWR. 


16. The draft master list identified the 1998 fecal coliforms listing for Ocklawaha River 

Above Daisy (WBID 2740D) as being in category 3b, but it was not identified as 


category 3c.] 

17. The draft master list identified the 1998 total coliforms and nutrients listings for 

Sweetwater Branch (WBID 2711) as being in category 3b, but these listing were not 

identified as having been included on the planning list per the IWR. [Acknowledged. 

Moved to category 3c.] 

Thank you for considering our comments. If you have any questions about our 

concerns, please feel free to contact Andrew Bartlett at (404) 562-9478. 

Sincerely, 

/s/

Standards, Monitoring & TMDL Branch


Statewide Comments 

GENERAL COMMENTS AND QUESTIONS 

1. EPA's comment letter states that the Group 2 - 5 waters will stay on the 1998 303(d) 

list until Florida assesses them under the Impaired Waters Rule. It is my 

understanding that previous lists cannot be carried over from one year to another and 

that when each new list is submitted, the previous list is then null. (If Florida has a 

different opinion about this legal requirement please cite the provision in federal law 

for amending a previous 303(d) list). So, if Florida is only submitting the Group 1 

waters that met the criteria for being impaired under the new Impaired Waters Rule, 

then EPA will be required by law to add the Group 2 - 5 waters to the official 2002 

303(d) list. Is that DEP's understanding of the procedure too and if not, then what is 

DEP's expectation in this regard [LindaYoung, Florida Clean Water Network] 

RESPONSE: As stated in the August 26 letter from EPA, the Department’s 2002 list 

will be submitted as an amendment to the 1998 list, with the amendments limited to 

certain water bodies in the Group 1 basins. As such, EPA will NOT be required to 

add the Group 2-5 waters to the EPA-approved 303(d) list for Florida – they will 

automatically stay on the list previously approved by EPA. While this approach (to 

limit the scope of the amendments to certain basins) is not specifically addressed in 

the federal TMDL regulations, it is consistent with the watershed management 

approach recommended by EPA. Other states that have implemented a rotating basin 

approach limit the scope of their 303(d) list submittals to the basins that they have 

assessed since their last 303(d) submittal to EPA. 

2. At the final DEP workshop on the draft 2002 list in August, Jerry Brooks stated that it 

was the Department's position that the waters on the list have no regulatory 

significance. I have two questions about this statement. First was he talking about the 

Group 2 - 5 waters that have not yet been assessed under the new Impaired Waters 

Rule, but are officially on the current 303(d) list or is he talking about all impaired 

waters on any 303(d) list Whatever category he was referring to, how does Florida 

legally consider any impaired waters list to have no regulatory significance when 

some regulatory authority would be required to enforce the provisions of section 

303(d) [L.Young, Florida Clean Water Network] 

RESPONSE: Your question seems to address the regulatory significance of the list 

AFTER a TMDL is developed, while Mr. Brooks’ response was focusing on whether 

the list itself (pre-TMDL) has any regulatory significance. Clearly, once TMDLs are 

developed and adopted by rule, the TMDLs will be have great significance to 

regulated (and unregulated) sources. However, we believe the key issue is whether 

the lists themselves have regulatory significance in the period between listing and 

TMDL development.


To address the issue of the regulatory significance of impaired waters lists, it is 

most appropriate to break out this topic into lists a) developed under 403.067(2), 

Florida Statutes (F.S.), which includes the current EPA-approved 303(d) list and any 

subsequent planning lists, and b) adopted under section 403.067(4), F.S. Regarding 

the former, paragraph (2) clearly states that there is no regulatory significance to these 

lists. As for any new lists adopted under paragraph (4), Mr. Brooks made the point 

that even these new lists currently have no regulatory significance because the 

ultimate permitting criteria (that permitted discharges must not cause or contribute to 

violations of water quality standards) is no different for discharges to listed waters 

than for non-listed waters. 

3. EPA says in paragraph one of their August 26 letter that the Group 1 waters for which 

DEP does not have sufficient data to assess under the Impaired Waters Rule, but 

which are on the current 1998 303(d) list, must remain on the "list". Does this mean 

these waters will be in Category 5 and on the verified list If not, then legally they are 

not on the 303(d) list – which means they are being delisted. Please clarify the status 

of these waters thoroughly so that the public can take appropriate actions. [L.Young, 

Florida Clean Water Network] 

RESPONSE: Please note that you paraphrased the language in the August 26 letter 

and added the word “must” to imply that EPA was forcing the Department to leave 

these waters on the 1998 list. However, since the implementation of the watershed 

approach, the Department has always committed that it would evaluate all waters on 

the 1998 list using the IWR methodology. As such, the Department had unilaterally 

agreed to keep these waters on the list approved until the data could be collected and 

the analysis undertaken. The letter was meant to document the understanding reached 

between Department and EPA staff. As for your specific question, these waters with 

insufficient data will be placed in category 3 because there are insufficient data to 

verify they are impaired pursuant to the IWR. While these waters will not be on the 

verified list adopted by the Secretary, they are not being “delisted” because they will 

remain on the 303(d) list approved by EPA. The Department and its monitoring 

partners will collect data on these waters so that they can be evaluated using the IWR 

methodology during the next watershed cycle. We are confident that this approach is 

consistent with the 1999 Florida Watershed Restoration Act, which clearly establishes 

two separate lists of impaired waters. 

4. How can the public get a copy of all the supporting data that EPA has requested If it 

is available electronically, please send it to me. [L.Young, Florida Clean Water 

Network] 

RESPONSE: We will send you a CD containing the data used for the assessment. 

(CD provided.)


5. Has DEP adopted an official policy regarding reasonable assurance requirements as 

related to 62-303.600 and if so how can the public get a copy of that policy If it is 

available electronically, please send it to me. [L.Young, Florida Clean Water 

Network] 

RESPONSE: We have attached a WORD version of the current draft guidance 

memo titled “Guidance for Development of Documentation to Provide Reasonable 

Assurance that Proposed Pollution Control Mechanisms will Result in the Restoration 

of Designated Uses in Impaired Waters.” 

6. How can the public get a copy of the documentation that has been provided to DEP 

by any entity that has requested a 62-303.600 exemption from listing an impaired 

water body Please provide a complete list of all such applications. [L.Young, Florida 

Clean Water Network] 

RESPONSE: As mentioned at the August 14 public meeting, we have received 

submittals from the Tampa Bay Estuary Program and the Suwannee Partnership. We 

have attached WORD versions of the main document for each submittal, but both 

submittals include extensive attachments that were provided in hard copy form only. 

If you want copies of the attachments, we can arrange an opportunity for you to 

obtain copies (at cost, as set forth in Chapter 119, F.S.). 

7. I think that it’s preposterous (sic) to revise any Acts that favor cleaning up our water 

for needless money saving measures, that we haven’t any idea what it will be put 

towards. [Bethany Pritchett] [Acknowledged. No response required.] 

COMMENTS ON WATERBODIES WITHIN OCKLAWAHA BASIN 

1. Roland Fulton of the SJRWMD provided comments on specific WBIDs. The 

comments dealt with PLRG schedules, identification of some SJRWMD projects, and 

concerns over possible use of stations from restoration areas. 

RESPONSE: Department staff subsequently met with SJRWMD staff in Palatka to 

discuss these issues. 

2. Frank Fuzzell sent an e-mail that apparently went to Jeff Newton at DOH regarding 

the possible affect of certain pesticides had on soil bacteria and fungi. [No response 

necessary.]


FORMAL PUBLIC MEETING COMMENTS (LEESBURG, FL., 7/23/02) 

The following comments made in the course of the presentations made by the 

Department at the Ocklawaha Basin Meeting held in Leesburg, 7/23/02. 

1. If the SWIM program has a PLRG for a certain pollutant, will you just accept their 

PLRG The Upper Ocklawaha Chain of Lakes PLRG is focused solely on 

phosphorus. Un-ionized ammonia is a real problem that needs to be considered along 

with pesticides and heavy metals. There are two point sources that discharge to Lake 

Griffin (City of Leesburg WWTF, Cutraele (old Cocoa Cola citrus plant). [Ms. Ann 

Griffin] 

RESPONSE: The FDEP is continuing to work with the St. Johns River Water 

Management District to coordinate completion of PLRGs in SWIM waters and the 

incorporation of these efforts into TMDLs that will result in the attainment of water 

quality standards. Chapter 62-303, FAC outlines a scientifically based methodology 

to evaluate surface waters and identify specific parameters that are causing 

impairments of designated uses. PLRGs will be evaluated with respect to the specific 

impairments identified and their ability to address those impairments. Lake Griffin 

was listed as impaired for nutrients and un-ionized ammonia. Phosphorus was 

determined to be the primary limiting nutrient. Based upon available data, specific 

metals or pesticides were not listed. A TMDL based upon phosphorus will directly 

result in a reduction of algal biomass and indirectly in a reduction in pH. Un-ionized 

ammonia levels are directly related to pH and water temperature, the lower the pH or 

water temperature the smaller the fraction of ammonia that is un-ionized. With 

respect to the two point sources, it is our understanding that the Central District is 

working with both permittee’s through the NPDES permitting process to address 

concerns over the operation and maintenance of those facilities. There may be cases 

where the PLRG does not address all of the pollutants that need TMDLs, in which 

case the Department will ensure a TMDL if developed. 

2. Particularly concerned about toxic algae and toxins released in the water in Lake 

Dora and whether this is being addressed in the listing process. Lake County Water 

Authority has a sampling program that has measured toxins in Lake Dora. She also 

asked why was the Silver River being proposed for delisting (nutrients). [Ms. Nancy 

Lopez] 

RESPONSE: Lake Dora (WBID 2831B or previously as 2831) has been listed for 

nutrients and un-ionized ammonia. Phosphorus has been identified as the limiting 

nutrient. Neither the State of Florida nor EPA has established a numeric criterion 

associated with specific algal species that may produce toxins or unacceptable 

concentrations of those toxins. There is ongoing research in both the areas of 

understanding the ecology of these species as well as assays to identify and test for 

toxins. Sampling information is appreciated and will be considered as part of the 

overall assessment process.


3. Silver River was being proposed for delisting for nutrients since chlorophyll levels in 

Silver River did not exceed the thresholds established in Chapter 62-303, FAC for 

placement on the planning or verified lists. There is a subsequent comment and 

response that elaborates on this issue. 

4. How are the deadlines established by courts from lawsuits implemented or 

incorporated into these lists [Ms. Nancy Lopez] 

RESPONSE: The dates provided on the lists reflects the dates by which EPA 

anticipates receiving TMDLs from the State of Florida. EPA has entered into a 

Consent Decree with Earthjustice that sets a schedule for all the water on Florida’s 

1998 303(d) list. A copy of the Consent Decree is available by contacting EPA’s 

Region 4 office in Atlanta, GA. 

5. How will ground water injection wells be addressed [Mr. Alex Streetler] 

RESPONSE: Generally speaking, ground water injection wells are not a part of the 

TMDL program. However, if the loads from these wells were to subsequently appear 

in the form of surface water loads and led to an impairment, then the loads to these 

wells would be included in the TMDL assessment. 

6. He and his wife live on Lake Griffin and have attended about 300 meetings by local, 

state, and federal agencies regarding water quality in the lake. Is the goal here to 

officially establish that Lake Griffin is in bad shape by August Rather frustrated that 

it has taken this long to reach such an obvious conclusion. [Mr. Bob Radcliff] 

RESPONSE: No response was needed, but DEP pointed out that the lake was 

included on the verified list. 

7. Concerned with the lack of dates on the verified list for the Upper Ocklawaha Chain 

of Lakes, particularly with Lake Griffin. Concerned that the WMD is only looking at 

phosphorus and should also be looking at nitrogen. [Ms. Ann Griffin] 

RESPONSE: The response at the public meeting was that in many cases dates were 

purposely omitted with the intent of soliciting input from the public as to priorities 

within the basin. It was also noted that most of these waters were identified in the 

Consent Decree between EPA and Earthjustice and had due dates of 2002. Updates 

versions of the master and draft verified impaired lists posted on the DEP website 

included these dates. Responses on Lake Griffin can be found to written comments 

provided by Ms. Griffin elsewhere in this document. 

8. Concerned about coliforms in Daisy Creek any whether it is still on the list. A 

number of sod farms in the area of Daisy Creek have been applying sewage sludge – 

couldn’t that be causing a coliform problem [Ms. Margie Beally]


RESPONSE: Daisy Creek (WBID 2769) remains on the planning list due to 

insufficient data. Repeated attempts were made over the past year to sample this 

waterbody, however, prolonged drought conditions resulted in a dry stream bed or 

stagnant conditions. FDEP has continued to schedule sampling surveys to obtain 

sufficient data to assess this waterbody using the impaired waters rule methodology. 

9. Question on the term “lake outlet.” There are some changes from the 1998 list and it 

seems that some segments no longer appear on the updated table. [Ms. Nancy Lopez] 

RESPONSE: A number of waterbody segments identified on the 1998 303(d) have 

been subdivided based upon the availability of additional data from a different 

waterbody type (lake, stream, estuary) within the original WBID or advances in the 

assessment process. Where changes have occurred, a comment was added that 

identified the original WBID number. Updated master lists have been subsequently 

posted on the DEP website that include all the WBIDs within a basin. 

10. A question was posed on the definition of TMDL given in the presentation. The 

definition does not include the word daily in it. Commenter was also concerned with 

the deadline of August 26 to receive comments and a signing date of August 28. 

Does not appear likely that anyone’s comments received on or around the 26 th are 

likely to be addressed by the 28 th . [Mr. Bernie Yokel] 

RESPONSE: We concur that the definition does not explicitly state that it must be a 

daily load and expect that for a number of TMDLs the appropriate unit of time will 

not be a day. The Code of the Federal Register (CFR) includes a definition for Total 

Maximum Daily Load (TMDL): 

40 CFR 130.2(i) – Total Maximum Daily Load (TMDL) - The 

sum of the individual WLAs for point sources and Las for nonpoint 

sources and natural background….TMDLs can be expressed in terms 

of either mass per time, toxicity, or other appropriate measure. 

Section 403.031(2) of Florida Statutes defines TMDL as the sum of the individual 

wasteload allocations for point sources and the load allocations for nonpoint sources 

and natural background. The definition does not specify as specific time unit. 

At these public meetings, people were encouraged to submit comments as soon as 

possible so that DEP will have adequate time to investigate and respond. Comments 

received up to the 26 th however will be reviewed and a response will be prepared. 

11. Do the dates in the table represent starting or completion dates for the TMDL Some 

of the dates are in parentheses, what does that mean [Mr. Ron Hart]


RESPONSE: The dates provided in the tables are the dates by which DEP is to 

provide a TMDL for that waterbody and pollutant to EPA. Generally, EPA will then 

approve the TMDL or propose a TMDL (if they disagree with the State’s TMDL or if 

the State fails to submit a TMDL). In these latter cases, EPA usually has up to 9 

additional months from the date shown to propose a TMDL. The dates in parentheses 

simply indicate that DEP was unable to verify that pollutant as needing a TMDL 

using the IWR methodology and the TMDL will fall to EPA complete by its required 

deadline. 

12. If you delist Silver River does that mean no further studies will be done on it Half 

mile Creek below SR 40 enters Silver River does not appear to be listed. Russ 

Frydenborg however has sampled this several times in the past two years. [Ms. 

Theresa Weaver] 

RESPONSE: This question was subsequently provided in writing. See response 

provided below. 

13. For waters identified with insufficient data, will there be any effort to collect 

additional data [Mr. Ron Hart] 

RESPONSE: The Department has committed to make every effort to gather the 

necessary data to assess all the waters on the 1998 303(d) list, if not in this 5-year 

cycle, then certainly before the next assessment cycle begins in 2005. However, a 

number of factors may limit our ability to collect the needed data, including limited 

state resources and a lack of rainfall. Data may be gathered by entities other than 

DEP, but must be done using proper quality assurance measures. A lack of water at 

some locations due to the drought and pumping of ground water remain as 

confounding issues. 

14. Once on the verified list what is the role for local government When should they 

participate and how are they affected by implementation [Mr. Rick Baird] 

RESPONSE: This is not a listing issue, however, DEP will continue to work closely 

with all affected stakeholders to explain the process and consequences of setting a 

TMDL and allocating the loads reductions required to meet water quality standards. 

15. How will new pollutants that had not been previously addressed or sampled be 

handled and make the list. His second question concerned how the modeling work 

presented in the status document was being used in this process. [Mr. Hulio 

Gonzolas] 

RESPONSE: Presumably, new pollutants (not previously on a 303(d) list) will be 

sampled over time to the point of having sufficient data to assess using the IWR 

methodology. While the Department has committed to sampling waters on the 

planning list, the Department has not committed to monitor all waters for all


parameters. For waters with local interest, but insufficient information for 

assessment, it is recommended that local resources within the affected watershed be 

solicited to more rapidly address this type of concern. 

As for the modeling presented in the Status Report, it was meant to provide 

information about the relative loading from point sources versus nonpoint sources, so 

that the Department could focus on the appropriate sources in the assessment and 

strategic monitoring phases. The modeling may also prove useful as we begin TMDL 

development for listed waters. 

16. For a number of lakes in the Upper Ocklawaha basin, there is considerable internal 

nutrient cycling. How is this addressed in the TMDL [Mr. David Walker] 

RESPONSE: This in not a listing question, but it will be addressed in the TMDL 

development phase. 

WRITTEN COMMENTS ON SPECIFIC WBIDS IN THE OCKLAWAHA BASIN 

1. The meeting was a waste of his time and wanted to know when something would be 

done that would be of benefit to the people that live and work along the lakes. [Mr. 

Dick Irwin] 

RESPONSE: I was disappointed to hear that you felt the meeting was a waste of 

time. While I'm not sure we will be able to fully address your concerns, I would very 

much appreciate it if you could more fully describe what type of 

information/discussion you believe would have been useful. I'm inclined to assume 

you would have preferred to talk about specific restoration actions and solutions to 

water quality problems (which we all would prefer), but I'd rather hear from you what 

you think would be more important - with the hope that we will better address your 

concerns at subsequent meetings. And there will be subsequent meetings where we 

will discuss proposed TMDLs and proposed restoration activities. (E-mail message 

from Daryll Joyner to Mr. Irwin on 7/24/02) 

2. Silver River (WBID 2772) Teresa Weaver was not satisfied with the explanation 

given at the public meeting for delisting the Silver River. 

RESPONSE: Based upon the methodology described in the IWR, the Silver River 

(WBID 2772) meets water quality standards for turbidity and nutrients. The Silver 

River remains on the master list for dissolved oxygen in the planning category. 

Segments of the Ocklawaha River just upstream (WBID 2740D) and downstream 

WBID 2740C) of the confluence of the Silver River with the Ocklawaha River are on 

the verified list for nutrients and dissolved oxygen. As discussed by Mr. Joyner at the 

public meeting, TMDLs will be developed for waters on the verified list. As part of 

that process, all sources contributing nutrients to those waters will be identified and 

assessed as to their contribution to the observed nutrient and dissolved oxygen


impairment. The Department is also aware of the four-year study on Silver Springs 

that is nearing completion by the USGS. 

3. Lake Griffin (WBID 2814A) - Ann Wettstein Griffin provided two sets of 

comments that focused upon Lake Griffin in particular and the Upper Ocklawaha 

chain of lakes in general. The concern expressed by Ms. Griffin was that the PLRG 

for Lake Griffin and other lakes in the chain is strictly based on phosphorus. Ms. 

Griffin was concerned that problems with microbes, pesticide metabolites, and 

metabolites of toxic algae, along with elevated nitrogen and un-ionized ammonia 

levels were not being addressed. Pollution from existing point sources was another 

area that Ms. Griffin did not feel was being adequately addressed. 

RESPONSE: Lake Griffin (WBID 2814A) is on the verified list for nutrients and 

un-ionized ammonia. Lakes Weir, Yale, Harris, Little Lake Harris, Beauclair in the 

Ocklawaha chain were also verified for nutrients. Lakes Dora and Eustis were 

verified for both nutrients and un-ionized ammonia. Under IWR, the Department was 

required to identify a limiting nutrient. As part of the TMDL process the Department 

will evaluate all sources of nutrients (nitrogen as well as phosphorus) to each lake, 

both from point and nonpoint sources and establish acceptable loadings that will 

restore and maintain water quality standards. 

Un-ionized ammonia levels are a function of the total ammonia concentration, 

water temperature, and pH. As water temperature or pH increases, the fraction of 

ammonia that is un-ionized also increases. Since algal blooms raise pH, a TMDL that 

addresses nutrients and algal biomass will also directly (lower ammonia levels) and 

indirectly (lower pH) affect un-ionized levels in the lake. 

It is our understanding that specific concerns related to the operation and 

maintenance of permitted point sources in the Lake Griffin area are being addressed 

by the Department’s Central District permitting staff. 

4. Alachua Sink (WBID 2720A) Brett Goodman from Gainesville Regional Utilities 

described their concerns with the potential consequences of listing and developing a 

nutrient TMDL for Alachua Sink before a thorough understanding of the waterbody 

and its possible impairment has been obtained. Specific concerns included possible 

discrepancies in the boundaries of Alachua Sink and its contributing watershed, 

whether it is appropriate to classify Alachua Sink as a lake, whether it is appropriate 

to use data from a stream channel station to determine the trophic status of the nearby 

lake features, whether the stream channel data is more appropriately characterizing 

conditions in Alachua Lake, and whether sampling during drought conditions is 

indicative of water quality during normal or high water periods. Given those 

concerns GRU proposed that further sampling and analysis be performed prior to the 

development of a nutrient TMDL for Alachua Sink. GRU also offered to participate 

and provide cooperative funding support for the additional analyses.


RESPONSE: With respect to the existing assessment of Alachua Sink, 

classification of Alachua Sink as a lake was considered more appropriate than as a 

stream. Most of the chlorophyll, total nitrogen, and total phosphorus data used to 

calculate TSI values were collected at a station described as Alachua Lake channel 

leading to Alachua Sink over the 2000 –2001 period. It is believed that this was the 

dominant input to Alachua Sink during this period and consequently was 

representative of water quality conditions in the sink during that period. Although 

sampling occurred during a drought, data requirements of the IWR were met. 

Staff from the WAS have discussed a cooperative approach to developing a 

TMDL for Alachua Sink that would involve identifying and quantifying point and 

nonpoint source contributions of nutrients to this watershed. This would include 

contributions from Alachua Lake, Sweetwater Branch, Extension Canal and other 

tributaries. A meeting has been proposed for October for Department, GRU, and 

Alachua County staff to meet and discuss what water quality/quantity information is 

available, ongoing or proposed projects that might influence water quality, and the 

type of additional information that needs to be collected to support TMDL 

development. 

Generic Comments on Groups 2 - 5 

GENERIC COMMENTS ON DELISTING NON-GROUP 1 WATERS 

1. Several comments were received in response to a Palm Beach Post article published 

on August 14, 2002 titled State Plays Dirty on Clean Water. Several comments dealt 

with the removal of 600 waterbodies from the State’s “impaired” list. (Aracelis 

Jaffe, Marian Towles, Rose Tancredi) 

Several comments dealt with altering the Clean Water Act to change the 

definitions for “impaired” waters. (Leann Drury, Maresa Pryor-Luzier, Thorgurdur 

Sudar, Wilma Katz, Marian Towles) 

RESPONSE: Numerous erroneous statements were made in the article with regard 

to FDEP’s listing process. Among the more notable was a statement that FDEP is in 

the process of removing 600 waterbody segments from the impaired list by changing 

the rules by which we assess waters. It should be noted that FDEP was not contacted 

by the author prior to publication of this article, which would have allow us to 

confirm facts and provide an explanation of the listing process. Each of the major 

points raised in the article will be addressed individually below. 

FDEP is not removing 600 water bodies from the State’s 303(d) list of impaired 

waters. We are in the process of developing new lists of impaired waters for specific 

basins in the State (termed Group 1 Basins) as part of the Department’s Watershed 

Management Approach. While only these new basin-specific lists will be verified as 

impaired under the State’s new methodology to identify impaired waters (the IWR),


we are not making any changes to the impaired waters list for other parts of the State 

at this time. 

Waters will not be taken off the impaired waters list unless we have clear 

evidence they are not impaired. As such, any waters on the 1998 303(d) list that are 

not in a Group 1 Basin will remain on the State’s list and will continue to receive 

additional priority funding under several federal grant programs. 

The statement attributed to Linda Young of the Florida Clean Water Network 

about the significance of the list is simply not correct. There are no state or federal 

laws that prohibit additional discharges to impaired waters. We are required to 

develop TMDLs for listed waters and these TMDLs will likely lead to limitations on 

existing dischargers for specific pollutants, but there is no moratorium on discharges 

simply by listing the water. More importantly, all wastewater discharges are fully 

evaluated as part of the permitting process, regardless of whether the receiving water 

is listed as impaired. We only authorize discharges after we have determined that the 

discharge will not cause water quality problems. 

No waters have been removed from the list “because plans exist to clean them up” 

as the article states. The IWR allows the Department to not list impaired waters if we 

have reasonable assurance that they will be restored because we want to encourage 

proactive restoration of state waters. The TMDL development process can take a 

long time, and there is no need to wait for a TMDL if local efforts are already 

addressing the source of the impairment without one. It is important to note that we 

have only received two such submittals statewide (from the Tampa Bay Estuary 

Program and the Suwannee Partnership). A presentation of reasonable assurance 

includes meeting many of the same requirements as would be required by a TMDL. 

Florida’s TMDL Program is gaining national recognition because it has developed 

comprehensive TMDL legislation (the 1999 Florida Watershed Restoration Act) and 

a rule to identify impaired waters (the IWR). The FWRA established a clear 

administrative process for the TMDL Program that ensures that all citizens, whether 

representing regulated parties, environmental groups, or themselves, can actively 

participate in all phases of the TMDL Program, ranging from listing decisions to the 

implementation of TMDLs. The subsequent IWR has established a strong, sciencebased 

foundation for the program, and we are confident that this foundation will 

allow us to target resources to the truly impaired waters, develop scientifically 

defensible TMDLs, and restore impaired waters in the most efficient manner possible. 

The IWR was developed through an extensive, open process with the assistance 

of a Technical Advisory Committee comprised of experts in various scientific fields. 

While public comments were encouraged throughout the rule development process, 

there were no changes made to the rule to allow industrial sources to avoid 

requirements to reduce pollution. Industrial representatives supported the rule 

because the vast majority of the impairment of state waters is caused by nonpoint 

sources (urban stormwater, agricultural runoff, septic tanks, and atmospheric 

deposition), and they support mechanisms that allow the State to appropriately 

expand restoration efforts on these other sources, rather than unfairly focusing all 

reductions on point sources.


Appendix I: Status of Assessed Waters as of January, 2003 

Further data from the planning and verified periods became available for assessment of the basin since the October, 2002 update of 

the 303(d) list and these data were used to update the listing status of waters. Table I.1 contains the listing status of all assessed 

waters in the basin as of January, 2003. All of the waters shown in Table I.1 are Class III freshwaters. It should be noted that 

subsequent to the October, 2002 update of the list, some waterbody segments were further subdivided to produce separate segments 

for lakes versus their surrounding watersheds. Therefore, in Table I.1, the WBID under which these segments were designated in the 

1998 303(d) list is shown as well as the new, or currently recognized, WBID for them.
