Kendal Lake
Iowa County, WisconsinMesotrophic
On the LakeGrade scale Kendal Lake grades a B, with clarity at 22.6 ft and 33 µg/L of phosphorus placing it above the Wisconsin median. Of the three parameters, phosphorus is the worst — at 33 µg/L of phosphorus, it keeps the lake susceptible to algal blooms in warm years.
The lake sits in the mesotrophic zone — the band where most well-managed Wisconsin lakes fall. 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.
