    Florida LAKEWATCH

    Florida LAKEWATCH

    Hot Off the Press: Lake Life, Classified!


    What’s Your Lake’s Trophic State? Learn how scientists classify lakes by biological productivity in FA268: Trophic State – A Waterbody’s Ability to Support Plants, Fish, and Wildlife. This UF/IFAS Florida LAKEWATCH guide uses water chemistry—chlorophyll, phosphorus, nitrogen, and clarity—to assess lake health. Great for managers, educators, and residents!
