Marion County Lake Quality

Florida, 108 lakes, measured by Florida DEP

Marion County in Florida carries 108 monitored lakes — one of the lake-richer counties in our dataset. Coverage that dense usually reflects active lake-association sampling alongside state-agency monitoring. 17 of those lakes carry recent nutrient and algae readings. The county-level summary describes that subset, not every water body listed. Most monitored lakes in Marion County carry favourable nutrient and algae readings for Florida.

Most of the county's monitored lakes are shallow, under 50 feet, which means wind keeps the water column mixed all summer and sediment-bound phosphorus releases back into the surface layer whenever the bottom is disturbed. Marion-Deerback Lake has the lowest nutrient and algae readings in the county.
