Starke County Lake Quality

Wisconsin, 2 lakes, average grade C (Fair)

Only 2 lakes in Starke County carry an active grade. The county-level summary is therefore representative of those specific lakes, not necessarily of every water body in the county. Starke County averages to a C. The distribution behind that average matters more than the letter: a few stressed lakes versus many decent ones can produce the same average as the inverse.

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. Wti-06 Lake (B) is the cleanest in the county.
