Dickinson County Lake Quality
Michigan, 13 lakes, average grade A (Excellent)
Dickinson County has 13 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. On average, Dickinson County lakes grade an A. That puts it near the top of the Michigan county ranking.
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. Louis Lake East Central Basin; Waucedah Township (A) is the cleanest in the county.
