Okauchee Lake Deep Hole Usgs vs Okauchee Lake Site

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

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

Both Okauchee Lake Deep Hole Usgs and Okauchee Lake Site sit in Wisconsin. A same-state comparison strips out the state-level water-quality regime as a variable: any grade differences here are about the lakes themselves, not the agencies grading them. These two are within a letter of each other on the rubric — Okauchee Lake Deep Hole Usgs (B) versus Okauchee Lake Site (B). The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.

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.
