Dewitt Road-Cedar Grove Lake

On the scoring rubric Dewitt Road-Cedar Grove Lake grades a D: clarity readings still being added and 74 µg/L of phosphorus keep it in the lower bracket for Sheboygan County. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

At a TSI of 66, Dewitt Road-Cedar Grove Lake reads as eutrophic — nutrient-rich enough that summer algal growth and reduced clarity are expected, not unusual. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. The lake's surface area is not consistently recorded across state datasets — physical context remains partial. Dewitt Road-Cedar Grove Lake ranks 6 of 6 in Sheboygan County — at the lower end of the locally monitored distribution.

No invasive species are currently listed at Dewitt Road-Cedar Grove Lake — the lake remains off the Wisconsin infested-waters roster. The state fisheries records do not list documented species for Dewitt Road-Cedar Grove Lake, which usually reflects a lack of formal fisheries survey work rather than an empty 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.
