Lake Lynn

Lake Lynn is a deep, sandy bottomed, clear, 'ridge' type lake located to the east of SR 17 north of the Town of Lake Placid.  Based on Lakewatch data, water quality in Lake Lynn is very good overall, though nitrogen levels are very high.  Phosphorus levels in Lake Lynn range from only 3 to 7 ppb and average a very low 5 ppb.  Nitrogen levels range from 1440 to 2700 ppb and average an extremely high 2165 ppb.  Algae populations, as estimated by the concentration of chlorophyll in the water, are usually quite low as a result of the low phosphorus levels found here.  Chlorophyll values range from 1 to 23 ppb, averaging 5 ppb.  The relatively low algae populations result in increased water clarity, which is measured by the depth to which a standardized 'secchi' disc can be seen when lowered into the water.  Secchi depths range from 9 to 23 feet and average 15 feet, making Lake Lynn among the clearest lakes in the county.  This lake is clear only due to a lack of phosphorus in the water - if large amounts of phosphorus ever enter the lake, the water can be expected to turn very green with severe algae blooms and water clarity will drop drastically.  No long term changes in water quality can be determined from the limited amount of data available.  Click here to view Lake Lynn water quality data by year.
