Report Assessment
Category
for WBID 6
1
The designation “stream” includes canals, rivers, and sloughs. The designation “lake” includes some marshes.
2
The state’s surface water classifications are as follows:
Class I: Potable water supplies
Class II: Shellfish propagation or harvesting
Class III: Recreation, propagation, and maintenance of a healthy, well-balanced population of fish and wildlife
Class IV: Agricultural water supplies
Class V: Navigation, utility, and industrial use (there are no state waters currently in this class)
3
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 an existing or proposed pollutant
control mechanism 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.
4
Parameters in bold meet the Verified List evaluation criteria, Section 62-303.400, F.A.C.
5
Parameters in italics are in Category 4 (a, b, or c) waters that do not require TMDL development.
6
The assessment categories listed in this column represent the status of each WBID as a whole, based on multiple
parameters. The hierarchy for assigning these categories is Category 5, then 4, then 3c, then 2, and then 3b, i.e., each WBID
is assigned a category based on the highest category assigned to an individual parameter. For example, if WBID 9999 has
total coliforms as Category 5, fecal coliforms as Category 3c, and coliforms-shellfish as Category 2, the single assessment
call for the WBID is Category 5.
F = Fresh water
M = Marine
DO = Dissolved oxygen
