Cass County Lake Quality

Michigan, 23 lakes, average grade C (Fair)

There are 23 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.

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. Stone Lake Central Basin; Jefferson Township (A) is the cleanest in the county.
