Divide Lake

Divide Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season.

Mesotrophic conditions dominate at Divide Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. Divide Lake reaches 22 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. At 61 acres, Divide Lake sits below the Minnesota median: a small water where shoreline activity has an outsized effect on water quality. Divide Lake ranks 64 of 142 in Lake County — solidly in the upper half of the local distribution.

No invasive species are currently listed at Divide Lake — the lake remains off the Minnesota infested-waters roster. 3 fish species are documented at Divide Lake, a mixed warm-water community typical for Minnesota lakes of this size. Public access is available — the lake is on the Minnesota PCA public-access list. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
