Jordan Pond vs Lake Dubay

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

Jordan Pond has a higher water quality grade (C, Fair) than Lake Dubay (D, Poor). Both are in Wisconsin.

Both Jordan Pond and Lake Dubay 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 Lake Dubay (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.
