Lake Wissota vs Moon Bay Lake

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

Lake Wissota and Moon Bay Lake both received the same overall water quality grade of D (Poor). Both are in Chippewa County, Wisconsin.

Both Lake Wissota and Moon Bay Lake 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. The grades are close: Lake Wissota (D) and Moon Bay Lake (D) 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 D. The tiebreakers come down to clarity (Lake Wissota: 3.5 ft, Moon Bay Lake: 3.7 ft) and what you want from the lake. Lake Wissota matches its peer on species count.
