Lake Letta
Lake Letta is a mucky-bottomed naturally stained 'transition' type lake located southeast of the City of Avon Park along SR 17. Based on Lakewatch data, water quality in Lake Letta is good for a lake of this type. Phosphorus levels range from a low 10 ppb to a moderately high 61 ppb (parts per billion), averaging only 19 ppb. Nitrogen levels are quite low for a transition lake, ranging from 130 to 680 ppb and averaging only 367 ppb. Algae levels, as measured by the concentration of chlorophyll in the water, are also quite low as a result of low nutrient levels. Chlorophyll levels range from 2 to 17 ppb and average only 6 ppb. The presence of algae and natural 'staining' of the water reduce 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 1.5 to 9.5 feet and average 4.3 feet, which is relatively deep for a transition type lake. Water quality appears to fluctuate naturally and there are no discernable changing trends in water quality that can be observed since Lakewatch sampling began in 1997.

The boat ramp on Lake Letta is located on the northeast side of the lake on boat ramp road, just west of State Road 17.
