Pike County Lake Quality
Wisconsin, 2 lakes, average grade D (Poor)

The county-wide average grade is D — water quality issues are persistent across most of the monitored basins. 1 lakes fall into the F bracket outright.
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 Wpa-06 Lake (C); the most-stressed is Wwl-10 Lake (F).
