No-Name Lake

Beltrami County, MinnesotaOligotrophic

On the LakeGrade rubric, No-Name Lake pulls an A: clarity at 42.7 ft and 11 µg/L of phosphorus put it in the top bracket for Minnesota. Sub-grades cluster within a single letter of each other, which usually means the lake is in stable trophic balance rather than fighting 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. Among the 86 graded lakes in Beltrami County, No-Name Lake ranks 15 — in the top quartile locally.

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.
