Little Prairie Lake vs Peaceful Valley Lake

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

Little Prairie Lake has a higher water quality grade (C, Fair) than Peaceful Valley Lake (C, Fair). Both are in Wisconsin.

Little Prairie Lake and Peaceful Valley Lake are both in Missouri — 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: Little Prairie Lake (C) and Peaceful Valley 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.
