Lizzie Lake

Lizzie Lake sits at the top of the Minnesota PCA grading rubric with an A, a mark reached by the cleanest lakes in 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 39 puts Lizzie Lake in the oligotrophic range, where biological productivity stays low and the water column remains clear. The lake's 66 ft maximum depth is in the upper tier for Minnesota — deep enough for cold-water fish to find refuge in summer. With 1,913 acres of surface and 9.7 miles of shoreline, Lizzie Lake is a large water by Minnesota standards — recreational pressure is spread across a long shoreline. Within Otter Tail County's 97 graded waters, Lizzie Lake sits at rank 9, near the top of the local distribution.

Lizzie Lake is on the Minnesota infested-waters list for zebra mussels — boaters should follow clean-drain-dry protocols when moving gear to or from the lake. Muskie are on the species list at Lizzie Lake, alongside the lake's 21 other documented fish. A documented public access point at Lizzie 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.
