Water Quality
Overall Trophic State Index
The Trophic State Index (TSI) measures the biological productivity of a lake. It takes into account nitrogen and phosphorus, nutrients required by plant life, and chlorophyll, which is a measure of algae abundance. Lakes with TSI values greater than 70 typically are “eutrophic”, with an oversupply of nutrients and degraded water quality.

Nutrient Chemistry
Although naturally present in all surface waters, excessive nutrients – nitrogen and phosphorus – are a nationwide water quality problem. They can cause overgrowth of plants that deplete the oxygen in the water needed by aquatic creatures to survive. Learn more about nutrient chemistry »

Water Clarity
Water clarity or turbidity measurements show the degree to which light is blocked by suspended particles such as sediment or algae. In a healthy aquatic system, sunlight is able to penetrate the water column and is available for photosynthetic plants and the creatures that depend on them. Learn more about water clarity »

Bacteria
Bacterial indicators for recreational waters include Fecal Coliform, Total Coliform, and Enterococcus (including E. coli). While indicator organisms themselves are not necessarily pathogenic, their presence suggests possible contamination which may result in human illness. Sources of this contamination include stormwater runoff, sewage overflows, and feces from wild and domestic animals. Learn more about bacteria »

Impaired Waters
This waterbody is not impaired according to the Florida Dept. of Environmental Protection's (FDEP) implementation of the Impaired Waters Rule (IWR). The FDEP evaluates whether waters meet their designated uses, which include aquatic life use support, primary contact and recreation use support, fish and shellfish consumption use support, and drinking water use support. Learn more about IWR Assessment »
Impairment Status
Not Impaired
Florida also has mercury impairment statewide, its largest source being atmospheric deposition from local and global power generation. The Florida Department of Health (DOH) and Florida Department of Environmental Protection have identified over 400 waterbodies, most freshwater lakes and rivers but also some coastal/marine areas, that are impaired due to mercury found in fish tissue. Florida Fish Consumption Advisories, updated annually by the DOH, provide guidance on how to limit mercury exposure from these waters.

Lake Vegetation Index (LVI)
The LVI is a rapid bioassessment tool created by the Florida Department of Environmental Protection (FDEP) to assess the biological condition of aquatic plant communities in Florida lakes. It utilizes a multi-metric index that evaluates how closely a lake's plant community compares to a lake containing minimal human disturbance (known as a reference lake) and is based on a field assessment of aquatic and wetland plants. Plants respond to disturbances such as the introduction of invasive exotic species (hydrilla as an example), lakeshore alterations such as creating beaches, and introduction of excess nutrients received by the surrounding watershed (use of fertilizers).

Aquatic Life Use Category | LVI Range | Description |
---|---|---|
Exceptional | 78 - 100 | Nearly every macrophyte present is a species native to Florida, invasive taxa typically not found. About 30% of taxa present are identified as sensitive to disturbance and most taxa have C of C values > 5. |
Healthy | 43 - 77 | About 85% of macrophyte taxa are native to Florida; invasive taxa present. Sensitive taxa have declined to about 15% and C of C values average about 5. |
Impaired | 0 - 42 | About 70% of macrophyte taxa are native to Florida. Invasive taxa may represent up to 1/3 of total taxa. Less that 10% of the taxa are sensitive and C of C values of most taxa are < 4. |
