Lake Tulane

Lake Tulane is a deep (70 feet), sandy-bottomed, clear 'ridge' type lake located in the City of Avon Park.  Lake Tulane has been estimated to be the oldest lake in North America, at approximately 40,000 years old.  Based on Lakewatch data, water quality in Lake Tulane is very good.  Phosphorus levels are very low, ranging from 2 to 14 ppb (parts per billion) and averaging 6 ppb.  Nitrogen levels are also very low, ranging from 240 to 810 ppb and averaging 510 ppb.  Algae levels, as estimated by the chlorophyll concentration in the water, are low as a result of the low nutrient levels.  Chlorophyll concentration range from 1 to 6 ppb and average 3 ppb.  Low algae levels result in a high degree of water clarity in most ridge type lakes, as measured by the depth to which a standardized 'secchi' disc can be seen when lowered into the water.  Secchi depths range from 11 to 30 feet and average 17 feet, making Lake Tulane among the very clearest lakes in the county.   Water quality fluctuates in this lake, as expected, but there does not appear to be a long term change in water quality since sampling began in 1995.  Click here to view water quality data by year.

The boat ramp for Lake Tulane is located on the west side of the lake where Edgeview Street meets Lakeview Boulevard.  Take Anoka Avenue south from Main Street in Avon Park to reach Edgewood, then turn left and follow the road until it runs into the lake.
