Clear Lake reads lower on nutrients and algae than Big Stone Lake. Both are in Oneida County, Wisconsin.

Reviewed by LakeQuality Editorial Team · Updated

Both Big Stone Lake and Clear Lake sit in Wisconsin. A same-state comparison strips out the state-level water-quality regime as a variable: any differences in the readings here are about the lakes themselves, not the agencies sampling them. The readings are close: Big Stone Lake and Clear Lake sit within a narrow band of each other on phosphorus, chlorophyll-a and clarity. The per-parameter table below shows where the small differences actually live.

With readings 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.

A green ✓ marks the better value for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better). Surface area and trophic state carry no tick — a bigger lake is not a better lake.

Verdict

Big Stone Lake and Clear Lake read the same on nutrients and algae overall. The tiebreakers come down to what you want from the lake. Big Stone Lake matches its peer on species count.
