Lost Land Lake vs Moose Lake
Water quality, depth, fish species, and recreation comparison.
Lost Land Lake has a higher water quality grade (A, Excellent) than Moose Lake (C, Fair). Both are in Sawyer County, Wisconsin.
Lost Land Lake and Moose 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. Lost Land Lake (A) is materially cleaner than Moose Lake (C). A gap that wide is unlikely to close in a single year of remediation work; it reflects multi-decade differences in the lakes themselves.
For a recreational visitor, the wider grade gap is decisive — Lost Land Lake is the better water-quality choice. For a researcher, the gap is the interesting part: what is different about the two watersheds, and which of those differences is mutable?
Lost Land Lake
Good clarity, visible to about 10 ft.
Moose Lake
Very murky, less than 2 ft of visibility.
Side-by-Side Metrics
| Metric | Lost Land Lake | Moose Lake |
|---|---|---|
| Overall Grade | A (Excellent) | C (Fair) |
| Water Clarity | 10 ft | 2 ft |
| Phosphorus | 17.2 µg/L | 28.9 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 21 ft | 21 ft |
| Surface Area | 1.3K acres | 1.6K acres |
| Public Access | Unknown | Unknown |
| Fish Species | 0 | 0 |
| Trophic State | mesotrophic | eutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Lost Land Lake wins on overall water quality with a Grade A versus Moose Lake's Grade C. Water clarity: 10 ft vs 2 ft. For fishing diversity, Lost Land Lake also leads with 0 species.
