Beatrice Lake

Beatrice Lake earns an A — water clarity, phosphorus, and chlorophyll-a all rate among the best monitored waters in Itasca County. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. A maximum depth of 29 ft puts Beatrice Lake in the middle of Minnesota's depth distribution. Beatrice Lake covers 124 acres alongside 4.1 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Among the 141 graded lakes in Itasca County, Beatrice Lake sits at rank 49, above the county median.

Beatrice Lake has no invasive species recorded in Minnesota state databases as of 2024, though prevention practices still apply at all access points. The fishery includes walleye alongside the lake's other 9 documented species — a notable draw for Minnesota anglers. Public access is available — the lake is on the Minnesota PCA public-access list. The lake has a long ice-out record — 32 observations on file, with a median ice-out around Apr 20. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
