Little Green Lake reads lower on nutrients and algae than Fox Lake. Both are in Wisconsin.

Reviewed by LakeQuality Editorial Team · Updated

Fox Lake and Little Green Lake are both in Wisconsin — a same-state head-to-head where the comparison comes down to lake-specific differences in depth, watershed, and monitoring history rather than the broader state-level water-quality regime. The readings are close: Fox Lake and Little Green 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.

Fox Lake

Dodge County, Wisconsin

Very murky, less than 2 ft of visibility.

Little Green Lake

Green Lake County, Wisconsin

Very murky, less than 3.2 ft of visibility.

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

Fox Lake and Little Green Lake read the same on nutrients and algae overall. The tiebreakers come down to clarity (Fox Lake: 2 ft, Little Green Lake: 3.2 ft) and what you want from the lake. Fox Lake matches its peer on species count.
