Suseq32a Lake

On the LakeGrade rubric, Suseq32a Lake pulls an A: clarity readings still being added and phosphorus readings still being added put it in the top bracket for Minnesota. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

A TSI value of 37 puts Suseq32a Lake in the oligotrophic range, where biological productivity stays low and the water column remains clear. 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 187 graded lakes in St. Louis County, Suseq32a Lake ranks 31 — in the top quartile locally.

Zebra mussels have been documented at Suseq32a Lake, which alters the filter-feeding balance and can paradoxically increase water clarity while disrupting the food web. The state fisheries records do not list documented species for Suseq32a Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. A documented public access point at Suseq32a Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. 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.
