Clay County Lake Quality

Florida, 45 lakes, measured by Florida DEP

The county-level average smooths over real differences — a single agricultural watershed near the southwest corner can pull the average down even if the rest of the county runs clean. 17 of those lakes carry recent nutrient and algae readings. The county-level summary describes that subset, not every water body listed. For Clay County the spread behind the average matters more than the average itself: a few nutrient-rich lakes among many clear ones produce the same figure as the inverse.

The county's lakes lean shallow, which makes the readings sensitive to wind, sediment-resuspension, and any nutrient inputs from the watershed. The cleanest measured lake is Clay-Lily Lake.
