Kenosha County Lake Quality
Wisconsin, 13 lakes, average grade C (Fair)
Kenosha County has 13 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 average is C — the middle of the rubric, with one or two lakes pulling the average up or down depending on year.
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 Paddock Lake (A); the most-stressed is George Lake (F).
