Rifle Lake vs Three Lake

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

Three Lake has a higher water quality grade (C, Fair) than Rifle Lake (D, Poor). Both are in Lake County, Minnesota.

Rifle 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: Rifle Lake (D) 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.

D

Rifle Lake

Lake County, Minnesota
