Campbell Lake

The LakeGrade rubric puts Campbell Lake at a C: clarity at 6.4 ft, 22 µg/L of phosphorus, and a TSI of 50 signal an intermediate trophic state. The lake's weakest score is on Secchi depth — the water looks more turbid than its phosphorus number alone would predict.

Mesotrophic conditions dominate at Campbell Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. Campbell Lake reaches 25 ft at its deepest point — typical for Minnesota mid-sized lakes, with seasonal stratification but limited cold-water refuge. At 463 acres, Campbell Lake fits the Minnesota median for monitored lakes, with 6.3 miles of shoreline. Campbell Lake ranks 75 of 86 in Beltrami County — at the lower end of the locally monitored distribution.

No invasive species are currently listed at Campbell Lake — the lake remains off the Minnesota infested-waters roster. Walleye are documented at Campbell Lake, one of 14 fish species on record for the lake. Public access is available — the lake is on the Minnesota PCA public-access list. The lake has a partial ice record — 15 observed ice-outs, centered near Apr 25. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
