Pickerel Lake

Pickerel Lake sits at the top of the Minnesota PCA grading rubric with an A, a mark reached by the cleanest lakes in Minnesota. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

A TSI value of 37 puts Pickerel Lake in the oligotrophic range, where biological productivity stays low and the water column remains clear. Pickerel Lake is unusually deep for Minnesota at 74 ft, which buffers the lake against summer warming and helps the deep water stay oxygenated. Pickerel Lake covers 361 acres alongside 7.4 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Within Becker County's 93 graded waters, Pickerel Lake sits at rank 6, near the top of the local distribution.

Zebra mussel presence at Pickerel Lake means the lake's clarity numbers carry an asterisk — filtered water is not the same as nutrient-poor water. Pickerel Lake's fishery is anchored by muskellunge, with 14 documented species in total — a destination water for muskie anglers. A documented public access point at Pickerel Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. Ice-out has been recorded 14 times at Pickerel Lake, with a median around Apr 25. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
