Bass Lake

Becker County, MinnesotaMesotrophic

On the LakeGrade rubric, Bass Lake pulls an A: clarity at 12.8 ft and 13 µg/L of phosphorus put it in the top bracket for Minnesota. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

A TSI near 41 places Bass Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. Bass Lake reaches 48 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. Bass Lake covers 130 acres alongside 2.8 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Among the 93 graded lakes in Becker County, Bass Lake ranks 18 — in the top quartile locally.

Bass Lake has no invasive species recorded in Minnesota state databases as of 2021, though prevention practices still apply at all access points. The fishery includes walleye alongside the lake's other 13 documented species — a notable draw for Minnesota anglers. Public access is available — the lake is on the Minnesota PCA public-access list. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.

From the 2024-07-22 survey

Bass Lake is a small (128 acre), relatively deep (48-foot maximum depth) lake located in east-central Becker County. The lakeshore is not heavily developed, with much of the north and east shorelines being county tax forfeited land. Becker County's Chilton Park is on the middle of the east shore, consisting of a boat…
