Waubeesee Lake
Racine County, WisconsinLimited DataOligotrophic
Waubeesee Lake earns an A — water clarity, phosphorus, and chlorophyll-a all rate among the best monitored waters in Racine County. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.
A TSI value of 27 puts Waubeesee Lake in the oligotrophic range, where biological productivity stays low and the water column remains clear. The lake's 73 ft maximum depth is in the upper tier for Wisconsin — deep enough for cold-water fish to find refuge in summer. At 139 acres, Waubeesee Lake fits the Wisconsin median for monitored lakes, with partial shoreline records. Among the 7 graded lakes in Racine County, Waubeesee Lake sits at rank 3, above the county median.
Zebra mussel presence at Waubeesee Lake means the lake's clarity numbers carry an asterisk — filtered water is not the same as nutrient-poor water. The fishery includes walleye alongside the lake's other 4 documented species — a notable draw for Wisconsin anglers. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
