Snowbank Lake

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

Mesotrophic conditions dominate at Snowbank Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. Snowbank Lake is unusually deep for Minnesota at 150 ft, which buffers the lake against summer warming and helps the deep water stay oxygenated. Snowbank Lake covers 4,655 acres alongside 43.1 miles of shoreline, large enough that conditions can vary meaningfully between bays. Snowbank Lake ranks 60 of 142 in Lake County — solidly in the upper half of the local distribution.

An invasive species record — spiny waterflea — has been logged at Snowbank Lake; Minnesota PCA maintains the official infested-waters list. Walleye are documented at Snowbank Lake, one of 11 fish species on record for the lake. Public access is available — the lake is on the Minnesota PCA public-access list. The lake has a partial ice record — 15 observed ice-outs, centered near Apr 29. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
