Lindberg Lake

Lindberg Lake earns a C — middle-of-the-pack water quality, with one or two parameters dragging the average down from a stronger grade. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

A TSI in the eutrophic range signals a lake doing what nutrient-loaded waters do — supporting an active algal community at the cost of clear water. Lindberg Lake reaches 19 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. At 95 acres, Lindberg Lake sits below the Minnesota median: a small water where shoreline activity has an outsized effect on water quality. Within the 40 graded lakes of Clearwater County, Lindberg Lake sits at rank 40, near the bottom of the county list.

No invasive species are currently listed at Lindberg Lake — the lake remains off the Minnesota infested-waters roster. Walleye are documented at Lindberg Lake, one of 9 fish species on record for the 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.
