Clear Lake vs Moen Lake
Water quality, depth, fish species, and recreation comparison.
Clear Lake has a higher water quality grade (B, Good) than Moen Lake (C, Fair). Both are in Oneida County, Wisconsin.
Clear Lake and Moen 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. These two are within a letter of each other on the rubric — Clear Lake (B) versus Moen Lake (C). The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.
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.
Clear Lake
No clarity data.
Moen Lake
Very murky, less than 2.8 ft of visibility.
Side-by-Side Metrics
| Metric | Clear Lake | Moen Lake |
|---|---|---|
| Overall Grade | B (Good) | C (Fair) |
| Water Clarity | No data | 2.8 ft |
| Phosphorus | 10.8 µg/L | 31 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 95 ft | 11 ft |
| Surface Area | 873 acres | 461 acres |
| Public Access | Yes | Yes |
| Fish Species | 6 | 6 |
| Trophic State | oligotrophic | eutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Clear Lake wins on overall water quality with a Grade B versus Moen Lake's Grade C. For fishing diversity, Clear Lake also leads with 6 species.
