Unnamed Lake

Unnamed Lake earns an F: phosphorus readings still being added and clarity at 1.1 ft signal heavy nutrient loading from the surrounding watershed. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

A TSI above 70 puts Unnamed Lake in hypereutrophic territory: visible blooms are common, and clarity rarely climbs even in early summer. 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 2 of 6 in Stevens 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. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
