Powers Lake

Kenosha County, WisconsinOligotrophic

Powers Lake earns an A — water clarity, phosphorus, and chlorophyll-a all rate among the best monitored waters in Kenosha County. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

Trophically, Powers Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. The lake bottoms out at 33 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. Powers Lake covers 451 acres alongside partial shoreline records — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Within Kenosha County's 13 graded lakes, Powers Lake ranks 7 — below the local median, though not at the bottom.

Zebra mussel presence at Powers Lake means the lake's clarity numbers carry an asterisk — filtered water is not the same as nutrient-poor water. Walleye are documented at Powers Lake, one of 5 fish species on record for the lake. 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.
