Sissabagama Lake and Stone Lake read the same on nutrients and algae. Both are in Wisconsin.

Reviewed by LakeQuality Editorial Team · Updated

Sissabagama Lake and Stone 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: Sissabagama Lake and Stone 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.

Sissabagama Lake

Sawyer County, Wisconsin

Moderate clarity, visible to about 8 ft.

Stone Lake

Washburn County, Wisconsin

Crystal clear, you can see 23 ft down.

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 B. The tiebreakers come down to clarity (Sissabagama Lake: 8 ft, Stone Lake: 23 ft) and what you want from the lake. Sissabagama Lake supports more documented fish species.
