Beartrack Lake
St. Louis County, MinnesotaLimited DataMesotrophic
Beartrack Lake comes in at a B on the grading rubric — a respectable showing for a Minnesota lake of its size and depth.
The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. At 55 ft of maximum depth, Beartrack Lake stratifies reliably through the summer — the hypolimnion stays cooler and clearer than the surface layer suggests. At 156 acres, Beartrack Lake fits the Minnesota median for monitored lakes, with 2.8 miles of shoreline. Beartrack Lake ranks 70 of 187 in St. Louis County — solidly in the upper half of the local distribution.
No invasive species are currently listed at Beartrack Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Beartrack Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Beartrack 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.
