Cass County Lake Quality

Michigan, 21 lakes, average grade C (Fair)

There are 21 graded lakes in Cass County. The mix is varied enough that the county-level average tells you the broad strokes, not the choose-this-cabin specifics. The county average is C — the middle of the rubric, with one or two lakes pulling the average up or down depending on year.

Many of the county's lakes are deep glacial basins — over 50 feet at their deepest point — which gives them thermal stratification and a buffer against summer warming. Diamond Lake (grade A) is the cleanest in the county.

NR = not rated: there is not enough recent sampling to support a letter. That is EPA Integrated Reporting Category 3 (insufficient information), not a failing grade. How grading works.
