Welcome to the <strong>Rivanna</strong> <strong>Watershed</strong><br />

The <strong>2012</strong> <strong>Rivanna</strong> <strong>Watershed</strong> <strong>Snapshot</strong> is a summary of the health and current<br />

conditions of the <strong>Rivanna</strong> <strong>River</strong> and its watershed.<br />

The <strong>Rivanna</strong> <strong>River</strong> drains 768 square miles of land from its headwaters in the Blue Ridge Mountains to<br />

its confluence with the James <strong>River</strong> at Columbia, Virginia. The <strong>Rivanna</strong> <strong>River</strong> is the largest tributary of the<br />

James <strong>River</strong> upstream of Richmond, Virginia.<br />

The <strong>Rivanna</strong> <strong>Watershed</strong> is 1/80 the size of the entire Chesapeake Bay<br />

watershed. The James <strong>River</strong> is a major tributary of the Chesapeake<br />

Bay, which is considered the largest estuary in North America.<br />

There are 7 jurisdictions that have some or all of their land area within the <strong>Rivanna</strong> <strong>Watershed</strong>, including<br />

the counties of Albemarle, Fluvanna, and Greene and<br />

the City of Charlottesville. Nelson, Louisa, and Orange % of<br />

The <strong>Rivanna</strong> <strong>River</strong> <strong>Basin</strong> Commission<br />

The <strong>Rivanna</strong> <strong>River</strong> <strong>Basin</strong> Commission (RRBC) was<br />

created with the vision that the river and its watershed<br />

can best be protected and conserved through regional<br />

cooperation and by seeking solutions across political<br />

boundaries. The RRBC members are the counties<br />

of Albemarle, Fluvanna, and Greene, the City of<br />

Charlottesville, and the Thomas Jefferson and Culpeper<br />

Soil and Water Conservation Districts.<br />

Resource management decisions are most effective<br />

when they are based on geography that is defined by<br />

natural systems, such as watersheds.<br />

What is a <strong>Watershed</strong>?<br />

A watershed is an area of land from which all<br />

water drains to a common waterway.<br />

Other terms used for a watershed are river<br />

basin or drainage basin.<br />

Look for me, Snappy the Snapping Turtle, for important information<br />

throughout this <strong>Snapshot</strong>. Snapping turtles are aquatic omnivores and<br />

help keep ponds and streams healthy. We are also one of the<br />

oldest living species, a true relic from the age of dinosaurs. For<br />

reasons not well understood, snapping turtles are declining<br />

in Virginia, so we have a lot at stake. A healthy and vital<br />

ecosystem serves all of us in the <strong>Rivanna</strong> <strong>Watershed</strong>.<br />

The <strong>Rivanna</strong> <strong>River</strong> joins the James <strong>River</strong> at Columbia, Virginia, about 50 miles upstream of Richmond.<br />

Our <strong>Watershed</strong> is Unique<br />

The Nature Conservancy has identified the<br />

<strong>Rivanna</strong> <strong>Watershed</strong> as one of the finest<br />

remaining freshwater river and stream systems in<br />

the Piedmont of Virginia.<br />

The <strong>Rivanna</strong> <strong>Watershed</strong> has many unique features and important<br />

designations, including:<br />

• A higher percentage of healthy streams than most other areas in<br />

Virginia, according to Virginia Commonwealth University.<br />

• Designation of the <strong>Rivanna</strong> Corridor as an American Treasure by<br />

the National Trust for Historic Preservation and the White House<br />

Millennium Council’s Save America’s Treasures program.<br />

• Many headwater streams originating in National Park Service<br />

lands along the Blue Ridge Parkway and in Shenandoah National<br />

Park.<br />

• Designation of the Upper Doyles <strong>River</strong> as an Exceptional State<br />

Water, home to brook trout and other cold-water fish.<br />

• An elevation change of 3,400 feet, from 3,580 feet above sea level<br />

in the Blue Ridge Mountains to 180 feet at Columbia, Virginia.<br />

• Over 2,000 miles of permanent and seasonal streams.<br />

• Approximately 4,250 acres of wetlands including agricultural<br />

wetlands and ponds.<br />

• Forest cover in over 70% of the watershed.<br />

• Home to 11 species of freshwater mussels, including globally rare<br />

James spinymussel, Atlantic pigtoe, and green floater.<br />

• Approximately 165,700 people living in the watershed, with<br />

population densities at the subwatershed level ranging from 10 to<br />

1,685 persons per square mile.<br />

• Many groups and individuals passionate about the <strong>Rivanna</strong> <strong>River</strong><br />

working to protect the water and natural resources here.<br />

Many <strong>Rivanna</strong> headwaters begin on the eastern slopes<br />

of the Blue Ridge Mountains, the interface between the<br />

Appalachians and the Piedmont. Photo/Mary Porter<br />

There is habitat in several <strong>Rivanna</strong> headwater streams for<br />

the James spinymussel (Pleurobema collina), a globally<br />

rare and federally and state endangered species. Photo/<br />

The <strong>Rivanna</strong> Conservation Society<br />

The <strong>Rivanna</strong> Conservation Society (RCS) was created in 1990 with the mission to safeguard<br />

the ecological, recreational, historical, cultural, and scenic resources of the <strong>Rivanna</strong> <strong>River</strong> and<br />

its tributaries. RCS hosts river paddles, river clean-ups, public education, teacher and student<br />

education, and stream and watershed restoration projects. RCS works to keep the health and<br />

protection of the <strong>Rivanna</strong> <strong>River</strong> at the forefront of our community’s environmental agenda.<br />

Water is the most critical resource issue of our lifetime and our children’s lifetime. The health of our waters is the principal measure of how<br />

we live on the land. –Luna Leopold, Hydrologist<br />

The <strong>Rivanna</strong> <strong>Watershed</strong> provides abundant opportunities for recreation and<br />

enjoying the outdoors.<br />

There are many opportunities for fishing, hiking,<br />

birdwatching, swimming, boating, and being in<br />

nature and close to water:<br />

• Over 170 miles of trails in the <strong>Rivanna</strong> <strong>Watershed</strong>,<br />

including the Fluvanna Heritage Trail and Rail Trail<br />

in Palmyra; Old Mills Trail in Albemarle; the <strong>Rivanna</strong><br />

Trail around Charlottesville; trails at Greene<br />

County Community Park; and headwater trails in<br />

Shenandoah National Park.<br />

• 9 public boat launches, including 5 state landings<br />

located directly on the <strong>Rivanna</strong> <strong>River</strong>, plus<br />

numerous spots along tributaries for launching<br />

kayaks and canoes.<br />

• The 38-mile <strong>Rivanna</strong> <strong>River</strong> Water Trail for paddling<br />

from from Darden Towe Park in Charlottesville to<br />

the James <strong>River</strong> at Columbia, with 2 camping sites<br />

along the way.<br />

• 12 miles of wild trout streams; 8 miles of stocked<br />

trout streams; and over 700 miles of perennially<br />

flowing streams.<br />

The removal of the Woolen Mills Dam in Charlottesville opened<br />

up fish passage for shad and other species, as well as new<br />

opportunities for recreation. Photo/Bill Emory<br />

There are fish species of ecological or<br />

economical importance (significant aquatic<br />

resources) in 65% of the <strong>Rivanna</strong> streams<br />

assessed by Virginia Commonwealth<br />

University in 2010. Brook trout,<br />

American eel, and smallmouth<br />

bass are among the 49 species<br />

of fish found in the watershed.<br />

Trails and fire roads in Shenandoah National Park provide options<br />

for walking, hiking, and running. Photo/RRBC<br />

Our Water Budget<br />

Just like a bank account balance, the relationship between<br />

water withdrawals, water discharges, and streamflow can be<br />

viewed as a “water budget.”<br />

We withdraw water from the <strong>Rivanna</strong><br />

<strong>Watershed</strong> for drinking and household<br />

needs, commercial and industrial uses,<br />

and irrigation for our crops and fields. Of all<br />

At Sugar Hollow Reservoir, the <strong>Rivanna</strong> Water and Sewer<br />

Authority (RWSA) releases water back to the Moormans<br />

<strong>River</strong> to match seasonal variations for the benefit of the<br />

downstream ecosystem. Photo/TJSWCD.<br />

How Much is a<br />

Million Gallons Per Day?<br />

One million gallons per day (MGD) is the<br />

equivalent of using the water from 1 ½<br />

Olympic-size swimming pools per day.<br />

• 97% to 99% is for public water supplies.<br />

• 1% to 3% is for agricultural operations and<br />

for irrigating golf courses.<br />

We put water back into the <strong>Rivanna</strong> <strong>River</strong><br />

primarily through discharges of treated<br />

waste from wastewater treatment plants,<br />

which are permitted by the Virginia Dept. of<br />

Environmental Quality (DEQ) and must meet<br />

water quality standards. For those of us with<br />

septic systems, our wastewater is treated<br />

before the liquid diffuses into surrounding<br />

soils. Water enters shallow and deep<br />

groundwater reserves, much of it eventually<br />

seeping back into streams.<br />

Stormwater runoff from rain and snow also<br />

finds its way to streams. Impervious surfaces<br />

(our roofs, driveways, sidewalks, parking<br />

lots, and roads) prevent the moisture from<br />

soaking into the ground and recharging the<br />

groundwater system.<br />

A healthy water budget balances human<br />

withdrawals and discharges and maintains<br />

streamflow levels needed to sustain<br />

aquatic life. Water conservation measures<br />

help ensure that there is the right amount of<br />

water flowing in area streams at the right time<br />

to support biological life and human needs.<br />

Permitted water usage during this period in the <strong>Rivanna</strong> <strong>Watershed</strong> has varied from<br />

almost 10 MGD to just over 13 MGD. Source/Annual Records (<strong>2012</strong>) from Virginia DEQ<br />

Healthy Waters, Water Consumption<br />

and Water Conservation<br />

The relationship between human water consumption, the level of<br />

water in streams, and stream health is affected by many factors,<br />

including precipitation patterns, water conservation (especially<br />

during dry periods), pumping of groundwater, and the amount of<br />

runoff generated by impervious surfaces. Wise use of our available<br />

resources can provide for our needs<br />

and those of aquatic and terrestrial living organisms.<br />

Monthly surface water permitted withdrawals and discharges are shown for a typical year<br />

while at the same time, discharges from treatment plants tend to be less because water<br />

used for irrigation increases consumption, but the water is not returned to streams via the<br />

treatment plants. Data source: Virginia DEQ.<br />

Stream health is related intimately to how<br />

we live on and use the land. As land use<br />

intensifies from rural to urban, stream health<br />

declines predictably.<br />

The 2011 StreamWatch Land Use Study predicts stream<br />

health based on the amount of forest and development<br />

in the surrounding area. The study finds:<br />

• Less forest and more impervious cover in the<br />

<strong>Watershed</strong> over time lead to unhealthy stream<br />

conditions.<br />

Impervious cover such as roads, parking lots, rooftops,<br />

and other hard surfaces strongly influence stream<br />

health. Photo/TJSWCD<br />

The 2009 <strong>Rivanna</strong> and Vicinity Map provides land use and land cover<br />

data to 1-meter resolution based on 2009 aerial imagery. RRBC,<br />

StreamWatch, and local government partners have used this imagery to<br />

analyze land use and to better understand and determine policies that<br />

could improve water quality in the <strong>Rivanna</strong> <strong>Watershed</strong>.<br />

• Unhealthy (impaired) streams have less aquatic life,<br />

more erosion along stream banks, and higher levels of<br />

various pollutants, including too much sediment.<br />

• Even relatively modest levels of land disturbance affect<br />

stream health.<br />

• More than half of the monitored semi-rural (or exurban)<br />

streams fail the biological water quality standard.<br />

• StreamWatch estimates that, within 20 years,<br />

increased development in non-urban areas could<br />

reduce the number of healthy streams by about 1/3.<br />

• Many of our <strong>Rivanna</strong> streams are “borderline” and can<br />

be restored to better water quality and maintained in a<br />

healthier condition.<br />

Impervious surfaces lead to higher stream flows which<br />

in turn cause more erosion along banks that are poorly<br />

stabilized. Photo/Center for <strong>Watershed</strong> Protection<br />

Downstream in Fluvanna County, the <strong>Rivanna</strong> <strong>River</strong><br />

swells with sediment-filled flow. Photo/Mary Porter<br />

An important aspect of watershed forest cover is the extent to<br />

which trees and vegetation are immediately adjacent to streams<br />

and rivers. A buffer densely vegetated with native trees and<br />

shrubs, 35 to 100 feet (or more) wide, can intercept runoff<br />

from adjacent lands and protect and stabilize stream banks.<br />

StreamWatch in the <strong>Rivanna</strong> <strong>Watershed</strong><br />

StreamWatch is the local stream monitoring non-profit that collects water<br />

quality data to support our community’s efforts to maintain and restore healthy<br />

waterways. StreamWatch collects and analyzes data with help from citizen<br />

volunteers and local professionals, and presents stream assessments and reports<br />

to partners, planners, managers, elected decision-makers, and the general public.

The Virginia DEQ has determined that 315 stream miles in the <strong>Rivanna</strong> do not<br />

meet Virginia water quality standards.<br />

The Virginia Department of Environmental Quality<br />

(DEQ) is responsible for assessing whether our<br />

waterbodies meet water quality standards, for<br />

one or more designated uses, such as fishing (the<br />

aquatic or biological standard) or swimming (the<br />

bacteria standard). Waterbodies that do not meet a<br />

designated use are listed as “impaired.”<br />

Based on draft <strong>2012</strong> data, Virginia DEQ reported:<br />

• 192 miles are impaired biologically (do not support<br />

aquatic life)<br />

• 123 miles are contaminated by bacteria (based on<br />

E.coli or fecal coliform indicators)<br />

Only half of the perennial streams in the <strong>Rivanna</strong><br />

<strong>Watershed</strong> have been assessed by DEQ. Many<br />

stream miles have more than one impairment.<br />

Based on StreamWatch’s data collected over 10<br />

years of monitoring in the <strong>Rivanna</strong>, about 70% of<br />

streams in the <strong>Rivanna</strong> <strong>Watershed</strong> are impaired for<br />

aquatic life.<br />

In addition to monitoring for the aquatic life<br />

standard, StreamWatch also monitors bacteria<br />

levels in the <strong>Watershed</strong>. Of the 13 monitoring sites<br />

in the <strong>Watershed</strong>, 7 are part of RCS’s Can You<br />

Swim Here? program that assesses public health<br />

concerns at popular swimming spots.<br />

The StreamWatch long-term monitoring program provides Virginia<br />

DEQ with significant amounts of high quality data that is used by<br />

DEQ to help assess water quality. Photo/StreamWatch<br />

The presence and types of macroinvertebrates (the larval stage of<br />

aquatic bugs) indicates the health of streams. Flathead mayflies<br />

(above) are generally found in cleaner waters. Photo/StreamWatch<br />

Ivy Creek is one of the many streams in the <strong>Rivanna</strong> <strong>Watershed</strong> that has<br />

too much sediment in the water after storms, reducing habitat for fish<br />

and other aquatic life. Photo/StreamWatch<br />

Excessive sediment (soil or dirt) is a major issue in the <strong>Rivanna</strong> <strong>Watershed</strong> because it smothers the<br />

aquatic life in the stream bed and reduces water quality. Sediment also fills up our reservoirs, reducing<br />

water storage capacity. Elevated levels of nutrients (phosphorus and nitrogen) lead to excessive<br />

growth of algae, decreased oxygen, reduced water clarity, and taste and odor problems in<br />

drinking water supplies. The U.S. Geological Survey (USGS) samples water quality at a gauge<br />

in Palmyra, Virginia, as part of the Chesapeake Bay monitoring network. Everything we<br />

do to improve local water quality will also help the James <strong>River</strong> and the Chesapeake Bay<br />

downstream from us.<br />

Water quality and natural resources can be<br />

protection mechanisms are permanent, while others are<br />

temporary, or time-limited.<br />

Conservation easements are a wonderful tool for protecting<br />

land. They allow a landowner to give up certain rights (such<br />

as the right to further develop the property), while retaining<br />

others (the right to engage in agriculture, harvest timber, and<br />

build a limited number of structures).<br />

Protecting large tracts of forests benefits water<br />

quality and helps maintain habitat for wildlife.<br />

Protected lands in headwaters and along the <strong>Rivanna</strong> <strong>River</strong> are<br />

especially important. Source/Protected land records (<strong>2012</strong>) from Virginia<br />

Department of Conservation and Recreation (DCR).<br />

A 100-foot wide stream side forested buffer, or<br />

vegetated strip, can reduce 97% of sediment, 80%<br />

of nitrogen, and 77% of phosphorus from<br />

entering streams. Further analysis is<br />

required to ascertain the quantity and<br />

quality of the buffers located along<br />

<strong>Rivanna</strong> streams.<br />

Many individual landowners practice good forest and land<br />

stewardship that helps protect the <strong>Rivanna</strong> <strong>River</strong> and the<br />

<strong>Watershed</strong>.<br />

From 2002 to <strong>2012</strong>, the Thomas Jefferson and Culpeper<br />

Soil and Water Conservation Districts have worked with<br />

landowners in the <strong>Rivanna</strong> <strong>Watershed</strong> and<br />

• Installed over 125 miles of stream fencing to keep<br />

livestock out of streams.<br />

• Planted or protected an estimated 640 acres of stream<br />

side buffers on agricultural land.<br />

Private landowners with horse and cattle operations,<br />

pastures and row crops, vineyards, and other agricultural<br />

activities have many tools for protecting soil and water.<br />

Many management practices are partially subsidized by<br />

state and federal cost-share programs.<br />

Stream exclusion fencing helps keep farm animals<br />

out of streams, thus reducing nutrient runoff, bank<br />

erosion, and excessive sedimentation.<br />

Most easements include measures to protect water<br />

quality for the public benefit, such as stream buffers<br />

that keep livestock, soil, and nutrients out of the<br />

river. Photo/Mary Porter

Management practices are being used<br />

across the <strong>Rivanna</strong> <strong>Watershed</strong> to treat<br />

runoff from urban and agricultural areas.<br />

Stormwater Best Management Practices<br />

Private landowners and the counties of Albemarle,<br />

Fluvanna, and Greene, the City of Charlottesville, and the<br />

University of Virginia together treat stormwater runoff<br />

from over 21,800 urban acres (4% of the watershed).<br />

Private landowners and local governments help reduce<br />

the impact of development projects on streams by:<br />

• Installing stormwater management practices at public<br />

sites wherever possible.<br />

• Encouraging private urban stormwater management<br />

practices through incentives and other financial tools.<br />

• Planting stream side buffers where possible and<br />

protecting and maintaining these buffers as land is<br />

developed.<br />

• Ensuring that streets and parking lots do not create<br />

impervious cover in excess of that needed for safe and<br />

orderly development.<br />

• Limiting construction on steep (or critical) slopes,<br />

especially adjacent to streams and creeks.<br />

• Steering higher density development to Urban<br />

Growth (or Development) Areas to help maintain rural<br />

character and protect natural resources.<br />

Pet Waste Management<br />

In Moores Creek and other urbanized watersheds, one of<br />

the main contributors to bacterial pollution is pet waste<br />

from dogs and cats. As our domesticated pet population<br />

grows, we need to manage pet waste properly<br />

if we want clean water.<br />

Greene County Community Park’s bioswale treats runoff<br />

from parking and playing fields. Native plantings ensure<br />

survivability during wet or hot and dry conditions.<br />

Virginia’s new stormwater regulations<br />

require local governments to develop<br />

enhanced local programs for<br />

reducing the quantity of<br />

stormwater and improving the<br />

treatment of stormwater<br />

before it is discharged to<br />

rivers and streams.<br />

The Future of Our <strong>Watershed</strong><br />

We are fortunate to live in the <strong>Rivanna</strong> <strong>Watershed</strong>, where many of our<br />

headwater streams are protected by National Park Service lands.<br />

We have ample opportunities for recreation and enjoyment along the <strong>Rivanna</strong> <strong>River</strong> and its streams.<br />

9<br />

We have a high percentage of streams with diverse habitat and fish species.<br />

Our local governments work to manage and protect our natural resources through innovative codes and<br />

ordinances and by setting an example of stewardship on public lands.<br />

Many landowners understand the ecological and economic importance of conserving land and water at<br />

home, on farms, and at businesses.<br />

Our Future<br />

The actions we take today to restore our<br />

impaired streams and to return our landscapes to<br />

healthy ecosystems will benefit our human and<br />

natural communities now and into the future.<br />

Elected officials, local government staff, and citizens join an educational<br />

tour of local stormwater projects to learn about new ways to manage<br />

stormwater (above, Crozet wetlands project). Photo/RRBC<br />

Stronger storms and longer periods of drought will require more robust<br />

and flexible water resource management. Photo/RRBC<br />

At the same time, over half of our assessed streams are degraded. Development results in more<br />

impervious surfaces that, if not properly managed, are damaging to our streams.<br />

We can improve the health of our watershed if we:<br />

Better Information to Support Better Policies<br />

We will make better decisions if we have better data on:<br />

• The health of all the streams in our watershed.<br />

• The location and density of stream side buffers.<br />

• The status of our groundwater resources and its<br />

projected level of use.<br />

• The impacts of emerging pollutants<br />

(pharmaceuticals, personal care products,<br />

and polyciclic aromatic hydrocarbons) on<br />

our streams.<br />

• The effectiveness of older, existing<br />

stormwater best management practices.<br />

• Improve stormwater management parcel-by-parcel, from fields, homes, and businesses,<br />

reducing damaging flows to our streams and increasing water resources for all.<br />

• Identify and protect the landscapes that best protect river and watershed health.<br />

• Improve forested stream buffers and systematically protect and restore these<br />

natural defense systems.<br />

• Use policies, incentives, and education to create a culture of watershed protection<br />

in our community.<br />

• Establish a water budget for all human and ecological needs and to inform water resource<br />

planning.<br />

• Monitor and plan for the impacts of changing weather patterns on our water resources<br />

and natural systems.<br />

• Develop tools for selecting the most effective and economical strategies for land<br />

and water conservation.<br />

• Continue to assess our progress with subsequent snapshots.<br />

A river is more than an amenity...It is a treasure. It offers a necessity of life that must be rationed among those who have power over it.<br />

A Roadmap and Tools for Working Together<br />

roadmap and decision support toolkit can help identify the most cost<br />

A effective and efficient strategies to guide our path forward.<br />

The <strong>Rivanna</strong> <strong>River</strong> <strong>Basin</strong> Commission is developing the <strong>Rivanna</strong> <strong>Watershed</strong> Action Plan and Toolkit<br />

for use by its member local governments, partners, stakeholders, and citizens to help inform and guide<br />

<strong>Rivanna</strong> protection and restoration. The planning process will build on the information in this <strong>Snapshot</strong><br />

and provide a road map and tools for guiding our work in the <strong>Rivanna</strong> <strong>Watershed</strong>.<br />

Working together, we can restore the <strong>Rivanna</strong> <strong>Watershed</strong> to support diverse habitats, provide the<br />

ecological services we rely on, and provide waters that are fishable and swimmable for all our citizens.<br />
