Vilas County Lake Quality

Wisconsin, 191 lakes, average grade B (Good)

Vilas County in Wisconsin carries 191 graded lakes — one of the lake-richer counties in our dataset. Coverage that dense usually reflects active lake-association sampling alongside state-agency monitoring. With an average grade of B, Vilas County sits comfortably above the Wisconsin median.

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 Razorback Lake (A); the most-stressed is East Bay Lake (F).
