Eddy by Pony Creek Lake vs Tilleda Off Bridge Lake

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

Eddy by Pony Creek Lake and Tilleda Off Bridge Lake both received the same overall water quality grade of F (Very Poor). Both are in Shawano County, Wisconsin.

Both Eddy by Pony Creek Lake and Tilleda Off Bridge 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: Eddy by Pony Creek Lake (F) and Tilleda Off Bridge Lake (F) 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.
