Wexford County Lake Quality
Wisconsin, 6 lakes, average grade B (Good)
Wexford County has 6 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. 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 Stone Ledge Lake (B); the most-stressed is Pleasant Lake (C).
