Unnamed Lake

Unnamed Lake sits at a C on the grading scale — not impaired, not pristine, with summer measurements that vary year to year. Clarity is the limiting factor — phosphorus is reasonable but suspended particles or algal cells keep water transparency below Minnesota norms.

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. A maximum depth of just 7 ft means sediment-bound phosphorus releases back into the water column whenever wind stirs the bottom — a classic shallow-lake dynamic. The lake is compact at 12 acres, with 0.7 miles of shoreline and little volume to buffer nutrient inputs. Unnamed Lake sits at rank 94 of 187 in St. Louis County, in the lower half of the local distribution.

Unnamed Lake has no invasive species recorded in Minnesota state databases as of 2022, though prevention practices still apply at all access points. Bass fishing is part of the appeal: the species list runs to 6, anchored by largemouth and/or smallmouth bass. No formal public access is documented at Unnamed Lake — most use is by shoreline residents and their guests. 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.
