Wells Lake reads lower on nutrients and algae than Roberds Lake. Both are in Rice County, Minnesota.

Reviewed by LakeQuality Editorial Team · Updated

Both Roberds Lake and Wells Lake sit in Minnesota. 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: Roberds Lake and Wells 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.

Roberds Lake

Rice County, Minnesota

Very murky, less than 2.5 ft of visibility.

Wells Lake

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

Roberds Lake and Wells Lake read the same on nutrients and algae overall. The tiebreakers come down to clarity (Roberds Lake: 2.5 ft, Wells Lake: 2 ft) and what you want from the lake. Roberds Lake supports more documented fish species.
