Barry County Lake Quality
Wisconsin, 9 lakes, average grade C (Fair)
Barry County has 9 graded lakes — a thin enough sample that one or two stressed lakes can move the county average noticeably. Use the per-lake pages below for what actually matters. The county average is C — the middle of the rubric, with one or two lakes pulling the average up or down depending on year.
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. Table Rock L. Ab. Carter Br. Lake (B) is the cleanest in the county.
