Unnamed Lake

On the LakeGrade scale Unnamed Lake grades a B, with clarity readings still being added and 28 µg/L of phosphorus placing it above the Wisconsin median. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. Unnamed Lake is small — 26 acres alongside partial shoreline records — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Within the 48 graded lakes of Washburn County, Unnamed Lake sits at rank 46, near the bottom of the county list.

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.
