Lost Land Lake and Teal Lake read the same on nutrients and algae. Both are in Sawyer County, Wisconsin.

Reviewed by LakeQuality Editorial Team · Updated

Lost Land Lake and Teal 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: Lost Land Lake and Teal 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.

Lost Land Lake

Sawyer County, Wisconsin

Good clarity, visible to about 10 ft.

Teal Lake

Sawyer County, Wisconsin

Murky, only visible to about 6.6 ft.

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 (Lost Land Lake: 10 ft, Teal Lake: 6.6 ft) and what you want from the lake. Lost Land Lake matches its peer on species count.
