Charlotte County Lake Quality
Florida, 7 lakes, average grade C (Fair)
Charlotte County has 7 graded lakes — a thin enough sample that one or two stressed lakes can move the county average noticeably. Use the per-lake pages below for what actually matters. Charlotte County averages to a C. The distribution behind that average matters more than the letter: a few stressed lakes versus many decent ones can produce the same average as the inverse.
The county's lakes lean shallow, which makes the grades sensitive to wind, sediment-resuspension, and any nutrient inputs from the watershed. The cleanest lake on the books is Charlotte-Casa-de-Medows Lake (B); the most-stressed is Charlotte-Sturgeon Lake (D).
