Unnamed Lake

On the scoring rubric Unnamed Lake grades a D: clarity at 4.3 ft and phosphorus readings still being added keep it in the lower bracket for Clark County. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

At a TSI of 56, Unnamed 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. Unnamed Lake is small — 7 acres alongside partial shoreline records — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Unnamed Lake ranks 1 of 4 in Clark County, putting it in the upper tier of locally monitored lakes.

No invasive species are currently listed at Unnamed Lake — the lake remains off the Wisconsin infested-waters roster. The state fisheries records do not list documented species for Unnamed Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
