Bass Lake

Crow Wing County, MinnesotaOligotrophic

Bass Lake earns an A — water clarity, phosphorus, and chlorophyll-a all rate among the best monitored waters in Crow Wing County. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

Trophically, Bass Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. Bass Lake reaches 47 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. At 121 acres, Bass Lake fits the Minnesota median for monitored lakes, with 3.3 miles of shoreline. Within Crow Wing County's 120 graded waters, Bass Lake sits at rank 13, near the top of the local distribution.

Bass Lake is on the Minnesota infested-waters list for zebra mussels — boaters should follow clean-drain-dry protocols when moving gear to or from the lake. Bass fishing is part of the appeal: the species list runs to 14, anchored by largemouth and/or smallmouth bass. The lake lacks a documented public access point, so visitor use is limited. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
