Clear Lake and Upper Sakatah Lake read the same on nutrients and algae. Both are in Minnesota.

Reviewed by LakeQuality Editorial Team · Updated

Clear Lake and Upper Sakatah Lake are both in Minnesota — 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: Clear Lake and Upper Sakatah 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.

Clear Lake

Waseca County, Minnesota

Very murky, less than 2.5 ft of visibility.

Upper Sakatah Lake

Le Sueur County, Minnesota

Very murky, less than 3 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

Both lakes earn the same Grade F. The tiebreakers come down to clarity (Clear Lake: 2.5 ft, Upper Sakatah Lake: 3 ft) and what you want from the lake. Clear Lake has fewer fish species than Upper Sakatah Lake.
