Sawyer County Lake Quality
Wisconsin, 49 lakes, average grade B (Good)
There are 49 graded lakes in Sawyer County. The mix is varied enough that the county-level average tells you the broad strokes, not the choose-this-cabin specifics. The county-wide average lands at B — solid water quality with most lakes carrying clear summer transparency and low-to-moderate phosphorus.
A meaningful share of Sawyer's lakes break 50 feet of depth, which matters because deep lakes hold cooler water all summer and resist the resuspended-sediment problems that plague shallow basins. The county's best-graded lake is Lac Courte Oreilles Lake (A).
