Jackson County Lake Quality
Florida, 7 lakes, average grade B (Good)
Only 7 lakes in Jackson County carry an active grade. The county-level summary is therefore representative of those specific lakes, not necessarily of every water body in the county. The county-wide average lands at B — solid water quality with most lakes carrying clear summer transparency and low-to-moderate phosphorus.
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 Lake Seminole (B); the most-stressed is Lake Seminole (B).
