Schuyler County Lake Quality
Wisconsin, 2 lakes, average grade C (Fair)
Only 2 lakes in Schuyler 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. Schuyler 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.
The county's lakes lean shallow, which makes the grades sensitive to wind, sediment-resuspension, and any nutrient inputs from the watershed. The cleanest lake on the books is Lamoka Lake (C); the most-stressed is Waneta Lake (D).
