Le Fjord-du-Saguenay County Lake Quality
Québec, 23 lakes, average grade B (Good)
Le Fjord-du-Saguenay County's 23 graded lakes fall in the moderate-density bracket for Québec. The county-level average smooths over real differences — a single agricultural watershed near the southwest corner can pull the average down even if the rest of the county runs clean. With an average grade of B, Le Fjord-du-Saguenay County sits comfortably above the Québec 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 Lac Clair (A); the most-stressed is Lac Vert (D).
