Little Bemidji Lake vs Round Lake

Water quality, depth, fish species, and recreation comparison.

Little Bemidji Lake and Round Lake both received the same overall water quality grade of A (Excellent). Both are in Becker County, Minnesota.

Both Little Bemidji Lake and Round Lake sit in Minnesota. A same-state comparison strips out the state-level water-quality regime as a variable: any grade differences here are about the lakes themselves, not the agencies grading them. These two are within a letter of each other on the rubric — Little Bemidji Lake (A) versus Round Lake (A). The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.

With grades this close, the choice between the two lakes turns on non-water-quality factors: depth, fish species, public access, distance from home. The per-lake pages below cover all of those.

Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).

Verdict

Both lakes earn the same Grade A. The tiebreakers come down to clarity (Little Bemidji Lake: 12.1 ft, Round Lake: 10.8 ft) and what you want from the lake. Little Bemidji Lake matches its peer on species count.
