Wpa-03 Lake vs Wpa-04 Lake

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

Wpa-03 Lake and Wpa-04 Lake both received the same overall water quality grade of C (Fair). Both are in Dubois County, Wisconsin.

Wpa-03 Lake and Wpa-04 Lake are both in Indiana — 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: Wpa-03 Lake (C) and Wpa-04 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 (Wpa-03 Lake: 5.7 ft, Wpa-04 Lake: 1.5 ft) and what you want from the lake. Wpa-03 Lake matches its peer on species count.
