Wind Lake
Racine County, WisconsinEutrophic
On the scoring rubric Wind Lake grades a D: clarity at 9.5 ft and 183 µg/L of phosphorus keep it in the lower bracket for Racine County. High phosphorus is the leading drag on the score — likely from upland agriculture, lawn runoff, or in-lake sediment release.
Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. Wind Lake reaches 47 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. Wind Lake covers 919 acres alongside partial shoreline records — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Within Racine County's 7 graded lakes, Wind Lake ranks 5 — below the local median, though not at the bottom.
Wind Lake is on the Wisconsin infested-waters list for zebra mussels — boaters should follow clean-drain-dry protocols when moving gear to or from the lake. The fishery includes walleye alongside the lake's other 6 documented species — a notable draw for Wisconsin anglers. Public access is available — the lake is on the Wisconsin DNR public-access list. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
