Bowman County Lake Quality
Wisconsin, 4 lakes, average grade C (Fair)
Only 4 lakes in Bowman 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. The county average is C — the middle of the rubric, with one or two lakes pulling the average up or down depending on year.
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 Lutz Dam Lake (B); the most-stressed is Gascoyne Lake (D).
