Low: Mpca Co-Located Site Lake

Lake of the Woods County, MinnesotaEutrophic

The LakeGrade rubric puts Low: Mpca Co-Located Site Lake at a C: clarity at 5.5 ft, 27 µg/L of phosphorus, and a TSI of 52 signal an intermediate trophic state. 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. 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. Low: Mpca Co-Located Site Lake sits at rank 6 of 11 in Lake of the Woods County, in the lower half of the local distribution.

Zebra mussels have been documented at Low: Mpca Co-Located Site 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 Low: Mpca Co-Located Site Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. Public access is available — the lake is on the Minnesota PCA public-access list. 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.
