Pleasant Lake

Stearns County, MinnesotaLimited DataMesotrophic

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

A TSI near 40 places Pleasant Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. Pleasant Lake reaches 33 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. At 218 acres, Pleasant Lake fits the Minnesota median for monitored lakes, with 3.5 miles of shoreline. Pleasant Lake ranks 17 of 55 in Stearns County — solidly in the upper half of the local distribution.

No invasive species are currently listed at Pleasant Lake — the lake remains off the Minnesota infested-waters roster. The fishery is bass-led, with 10 documented species across the lake's records. A documented public access point at Pleasant Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. The lake has a partial ice record — 7 observed ice-outs, centered near Apr 11. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
