No-Name Lake

Beltrami County, MinnesotaOligotrophic

On the LakeGrade rubric, No-Name Lake pulls an A: clarity at 13.0 ft and 11 µg/L of phosphorus put it in the top bracket for Minnesota. With clarity and phosphorus scored, the sub-grades cluster within a letter of each other, pointing to stable conditions rather than one specific stressor.

Trophically, No-Name Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. 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. No-Name Lake ranks 40 of 92 in Beltrami County — solidly in the upper half of the local distribution.

No invasive species are currently listed at No-Name Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for No-Name Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. Monitoring depth is thin here: the LakeGrade rubric is applied to a small number of sample years, and the grade will be revised as more data accumulates.
