Racine County Lake Quality
Wisconsin, 7 lakes, average grade C (Fair)
Only 7 lakes in Racine 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 average is C — the middle of the rubric, with one or two lakes pulling the average up or down depending on year.
Many of the county's lakes are deep glacial basins — over 50 feet at their deepest point — which gives them thermal stratification and a buffer against summer warming. Browns Lake (grade B) is the cleanest in the county.
