Jackson County Lake Quality
Wisconsin, 9 lakes, average grade C (Fair)
Only 9 lakes in Jackson 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. Jackson 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. Farewell Lake West Basin; Hanover Township (A) is the cleanest in the county.
