Suseq44a Lake

Lake County, MinnesotaLimited DataOligotrophic

Suseq44a Lake earns an A — water clarity, phosphorus, and chlorophyll-a all rate among the best monitored waters in Lake County. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

A TSI value of 36 puts Suseq44a 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 142 graded lakes in Lake County, Suseq44a Lake ranks 32 — in the top quartile locally.

Zebra mussels have been documented at Suseq44a 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 Suseq44a Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. A documented public access point at Suseq44a Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
