Lake Thompson vs Moen Lake
Water quality, depth, fish species, and recreation comparison.
Lake Thompson reads lower on nutrients and algae than Moen Lake. Both are in Oneida County, Wisconsin.
Lake Thompson 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. The readings are close: Lake Thompson and Moen 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.

| Water Clarity | 4 ft Better | 2.8 ft |
| Phosphorus | 22.4 µg/L Better | 31 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 30 ft Better | 11 ft |
| Surface Area | 401 acres | 461 acres |
| Public Access | Yes | Yes |
| Fish Species | 6 | 6 |
| Trophic State | eutrophic | eutrophic |
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.
