Oneida County Lake Quality
Wisconsin, 134 lakes, average grade C (Fair)
Oneida County in Wisconsin carries 134 graded lakes — one of the lake-richer counties in our dataset. Coverage that dense usually reflects active lake-association sampling alongside state-agency monitoring. 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 Clear Lake (A); the most-stressed is Rice Lake (F).
