Lake Glenada

Lake Glenada is a mucky-bottomed, naturally stained 'transition' type lake located just south of the City of Avon Park and the South Florida Community College on the east side of US 27.  Water quality in Lake Glenada is generally poor.  Based on Lakewatch data, nutrient levels are very high, algae blooms are frequent and extreme and water clarity is somewhat low.  Phosphorus levels range from 46 ppb (parts per billion) to an extremely high 214 ppb, averaging a very high 108 ppb.  Nitrogen levels range from 760 to 2740 ppb and average a somewhat high 1414 ppb.  As a result of high nutrient levels, algae populations frequently increase to cause 'blooms,' as measured by the chlorophyll concentration in the water.  Chlorophyll levels range from 24 ppb to a very high 143 ppb, averaging 68.  Water clarity declines as algae populations increase and is measured by the depth to which a standardized 'secchi' disc can be seen when lowered into the water.  Secchi depths range from 1.5 to 3.5 feet and average 2.6 feet.  There may be a slight increase in lake nitrogen concentrations in recent years compared to 1995-96, though this cannot be determined for certain.  Sources of nutrients causing the poor water quality in this lake should be identified.  Click here to view water quality data by year.

The boat ramp for Lake Glenada is located on the west side of the lake just off US 27.  The parking area is just south of the restaurant.
