West Pike Lake
Cook County, MinnesotaLimited DataOligotrophic
West Pike 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.
Trophically, West Pike Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. West Pike Lake is unusually deep for Minnesota at 120 ft, which buffers the lake against summer warming and helps the deep water stay oxygenated. At 788 acres, West Pike Lake fits the Minnesota median for monitored lakes, with 10.0 miles of shoreline. Among the 128 graded lakes in Cook County, West Pike Lake ranks 29 — in the top quartile locally.
No invasive species are currently listed at West Pike Lake — the lake remains off the Minnesota infested-waters roster. Bass fishing is part of the appeal: the species list runs to 5, anchored by largemouth and/or smallmouth bass. No formal public access is documented at West Pike Lake — most use is by shoreline residents and their guests. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.

From the 2025-08-12 survey
Temperature and dissolved oxygen measurements were collected from the deepest basin in West Pike Lake on August 11th, 2025. This was done to evaluate the quantity and quality of cold, oxygenated water (i.e., oxythermal habitat) available to Lake Trout, the most sensitive coldwater species present in this lake (Cisco,…
