Wabaunsee County Lake Quality
Kansas, 4 lakes, average grade C (Fair)
Only 4 lakes in Wabaunsee 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. Wabaunsee 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 New Alma City Lake (B); the most-stressed is Nla Lake (D).
