Jordan Pond vs Mcdill Pond

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

Jordan Pond and Mcdill Pond both received the same overall water quality grade of C (Fair). Both are in Portage County, Wisconsin.

Both Jordan Pond and Mcdill Pond 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: Jordan Pond (C) and Mcdill Pond (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 (Jordan Pond: 4 ft, Mcdill Pond: 5 ft) and what you want from the lake. Jordan Pond matches its peer on species count.
