Unnamed Lake

Unnamed Lake earns an F: 269 µg/L of phosphorus and clarity at 0.7 ft signal heavy nutrient loading from the surrounding watershed. The two scored sub-grades — clarity and phosphorus — track close together, so neither one is dragging the average down.

Hypereutrophic conditions mean the lake is operating at the upper end of the productivity scale, with all the bloom risk that implies. 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. Within the 10 graded lakes of Grant County, Unnamed Lake sits at rank 8, near the bottom of the county list.

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. The lake lacks a documented public access point, so visitor use is limited. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
