Lost Land Lake vs Teal Lake
Water quality, depth, fish species, and recreation comparison.
Lost Land Lake and Teal Lake both received the same overall water quality grade of B (Good). Both are in Sawyer County, Wisconsin.
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 grades are close: Lost Land Lake (B) and Teal Lake (B) are within one letter of each other on the LakeGrade rubric. The per-parameter sub-grades below will show where the small differences actually live.
With grades 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
Good clarity, visible to about 10 ft.
Teal Lake
Murky, only visible to about 6.6 ft.
Side-by-Side Metrics
| Metric | Lost Land Lake | Teal Lake |
|---|---|---|
| Overall Grade | B (Good) | B (Good) |
| Water Clarity | 10 ft | 6.6 ft |
| Phosphorus | 17.1 µg/L | 16.5 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 21 ft | 31 ft |
| Surface Area | 1,264 acres | 1,024 acres |
| Public Access | Yes | Yes |
| Fish Species | 6 | 6 |
| Trophic State | mesotrophic | mesotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
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.
