Kendal Lake

The LakeGrade rubric puts Kendal Lake at a C: clarity at 6.9 ft, 33 µg/L of phosphorus, and a TSI of 52 signal an intermediate trophic state. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

A TSI in the eutrophic range signals a lake doing what nutrient-loaded waters do — supporting an active algal community at the cost of clear water. Kendal Lake reaches 17 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. Kendal Lake is small — 32 acres alongside partial shoreline records — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Among the 6 graded lakes in Iowa County, Kendal Lake sits at rank 3, above the county median.

No invasive species are currently listed at Kendal Lake — the lake remains off the Wisconsin infested-waters roster. Walleye are documented at Kendal Lake, one of 5 fish species on record for the lake. Monitoring depth is thin here: the LakeGrade rubric is applied to a small number of sample years, and the grade will be revised as more data accumulates.
