Charlevoix-Est County Lake Quality
Québec, 5 lakes, average grade B (Good)
Charlevoix-Est County has 5 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. With an average grade of B, Charlevoix-Est County sits comfortably above the Québec median.
Most of the county's monitored lakes are shallow — under 50 feet — which means wind keeps the water column mixed all summer and sediment-bound phosphorus releases back into the surface layer whenever the bottom is disturbed. Lac DeschêNes (A) is the cleanest in the county.
