Overall Trophic State Index

"Trophic" means "relating to nutrition." The Trophic State Index (TSI) takes into account chlorophyll, nitrogen, and phosphorus, which are nutrients required by plant life. The Florida Department of Environmental Protection (FDEP) uses this information to determine a rating for the waterbody. Learn more about the Trophic State Index »

      Water Clarity

      Water clarity or turbidity measures the degree to which light is blocked because the water is cloudy or contains suspended particles, such as algae. Water clarity is one indicator of a waterbody's ability to sustain plants and wildlife. Learn more about water clarity »

        Bacteria

        The currently used bacterial indicators for recreational waters include total coliform, fecal coliform and enterococcus. Indicator organisms themselves are not necessarily pathogenic but their presence "indicates" or suggests recent contamination by human sewage or other waste which may result in human illness. Sources of contamination include storm water runoff, sewage overflows and feces from wild and domestic animals. Learn more about bacteria »

          Dissolved Oxygen

          Dissolved Oxygen (DO) is one of the most important indicators of water quality. It is essential for the survival of fish and other aquatic organisms. Learn more about dissolved oxygen »

            Impaired Waters

            The Impaired Waters Data is the most recent available data from FDEP, but it may not reflect the current FDEP impaired list. These data are updated when and as soon as they are made available from FDEP.

            Impaired

            This waterbody is impaired according to the State of Florida's Impaired Waters Rule (IWR) Chapter 62-303 F.A.C. that governs the Total Maximum Daily Loads (TMDL) Program or according to the U.S. Environmental Protection Agency (EPA). Identification of Impaired Surface Waters (IWR) is a new scientific approach for guiding Florida Department of Environmental Protection process for identifying and prioritizing impaired surface waters in Florida. The rule evaluates whether waters meet their designated uses for a particular analyte, which include aquatic life use support, primary contact and recreation use support, fish and shellfish consumption use support, and drinking water use support. All water resources in this county are designated as Class III waters. Class III waters are considered recreational use waters, which means that the water should be fishable and swimmable. Class II waters are for shellfish propagation and harvesting. Class I waters are considered potable (drinkable) water supplies. As part of the terms of a court order related to the 1998 303(d) list of impaired waters, some waters are listed as impaired by EPA but not listed by the State of Florida.
