Lake Francis
Lake Francis is a sandy bottomed, clear, ridge type lake located north of Lake June, northwest of the town of Lake Placid. Based on Lakewatch data, water quality in Lake Francis is good, though there MAY have been a SLIGHT decline in the past year due to increased nitrogen levels. Additional years of data are needed to determine whether there is a long term increase in nitrogen or simply a short term fluctuation. Nitrogen levels range from 240 to 920 ppb (parts per billion), averaging 530 ppb. Phosphorus ranges from 5 to 26 ppb and averages 14 ppb. Algae populations, as measured by the concentration of chlorophyll in the water, increase and decrease as nutrient levels increase and decrease. Chlorophyll levels range from 2 to 30 ppb and average 10 ppb. Water clarity is affected by algae populations and is measured by the depth to which a standardized 'secchi' disc can be seen when lowered into the water. Secchi depths in Lake Francis range from 3 to 12 feet and average a healthy 7 feet. Click here to view water quality data by year.
The boat ramp for Lake Francis is located on the southeast corner of the lake off of Cloverleaf Road.
