Boone County Lake Quality
Wisconsin, 1 lakes, average grade A (Excellent)
Only 1 lakes in Boone 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. On average, Boone County lakes grade an A. That puts it near the top of the Indiana county ranking.
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. Wwu-11 Lake (A) is the cleanest in the county.
