Ocauchee Lake vs Okauchee Lake Deep Hole Usgs

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

Ocauchee Lake and Okauchee Lake Deep Hole Usgs both received the same overall water quality grade of B (Good). Both are in Waukesha County, Wisconsin.

Ocauchee Lake and Okauchee Lake Deep Hole Usgs are both in Wisconsin — 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: Ocauchee Lake (B) and Okauchee Lake Deep Hole Usgs (B) 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 B. The tiebreakers come down to clarity (Ocauchee Lake: 6.6 ft, Okauchee Lake Deep Hole Usgs: 7.5 ft) and what you want from the lake. Ocauchee Lake matches its peer on species count.
