Kenosha County Lake Quality
Wisconsin, 13 lakes, average grade A (Excellent)
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's average grade is A — among the cleanest in Wisconsin. 10 lakes pull an A on their own, and almost none fall into the D or F brackets.
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 Silver Lake (A); the most-stressed is Lake Shangrila -Benet (C).
