Crow Wing County Lake Quality

Minnesota, 120 lakes, average grade B (Good)

Crow Wing County has 120 graded lakes, enough that within-county variation matters as much as the county average. Some are deep glacial basins, others are shallow agricultural-watershed waters, and the grade distribution reflects that mix. With an average grade of B, Crow Wing County sits comfortably above the Minnesota 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 East Fox Lake (A); the most-stressed is Mud Lake (D).
