Outlet To Lake Geneva vs Powers Lake
Water quality, depth, fish species, and recreation comparison.
Powers Lake has a higher water quality grade (A, Excellent) than Outlet To Lake Geneva (D, Poor). Both are in Wisconsin.
Outlet To Lake Geneva and Powers 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 meaningfully apart: Powers Lake grades a A while Outlet To Lake Geneva grades a D. That two-letter spread reflects real underlying differences — different watershed inputs, different depth profiles, or different monitoring rigor.
For a recreational visitor, the wider grade gap is decisive — Powers 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?

Side-by-Side Metrics
| Metric | Outlet To Lake Geneva | Powers Lake |
|---|---|---|
| Overall Grade | D (Poor) | A (Excellent) Better |
| Water Clarity | No data | 10 ft |
| Phosphorus | 658 µg/L | 17.2 µg/L Better |
| Chlorophyll-a (Algae) | No data | 3.4 µg/L |
| Maximum Depth | 135 ft Better | 33 ft |
| Surface Area | 5,401 acres | 451 acres |
| Public Access | Yes | Yes |
| Fish Species | 6 Better | 5 |
| Trophic State | hypereutrophic | mesotrophic |
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.
