Unnamed Lake

On the scoring rubric Unnamed Lake grades a D: clarity at 3.6 ft and 72 µg/L of phosphorus keep it in the lower bracket for Grant County. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

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. 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. Unnamed Lake ranks 3 of 10 in Grant County — solidly in the upper half of the local distribution.

No invasive species are currently listed at Unnamed Lake — the lake remains off the Minnesota 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. No formal public access is documented at Unnamed Lake — most use is by shoreline residents and their guests. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
