| Public Access | Yes | Yes |
| Fish Species | 13 | 15 Better |
| Trophic State | oligotrophic | oligotrophic |
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.
