Nipissing District County Lake Quality
Ontario, 269 lakes, average grade B (Good)
Nipissing District County in Ontario carries 269 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-wide average lands at B — solid water quality with most lakes carrying clear summer transparency and low-to-moderate phosphorus.
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 Animoosh Lake (A); the most-stressed is Utim Lake (F).
