One Lake vs Three Lake

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

One Lake and Three Lake both received the same overall water quality grade of C (Fair). Both are in Lake County, Minnesota.

One Lake and Three Lake are both in Minnesota — a same-state head-to-head where the comparison comes down to lake-specific differences in depth, watershed, and monitoring history rather than the broader state-level water-quality regime. The grades are close: One Lake (C) and Three Lake (C) are within one letter of each other on the LakeGrade rubric. The per-parameter sub-grades below will show where the small differences actually live.

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 C. The tiebreakers come down to clarity (One Lake: 7.5 ft, Three Lake: 8 ft) and what you want from the lake. One Lake matches its peer on species count.
