Crowder S.P. Lake vs Jamesport Community Lake

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

Crowder S.P. Lake and Jamesport Community Lake both received the same overall water quality grade of F (Very Poor). Both are in Wisconsin.

Crowder S.P. Lake and Jamesport Community 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: Crowder S.P. Lake (F) and Jamesport Community Lake (F) 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 F. The tiebreakers come down to clarity (Crowder S.P. Lake: 1 ft, Jamesport Community Lake: 0.9 ft) and what you want from the lake. Crowder S.P. Lake matches its peer on species count.
