Franklin Lake vs Kentuck Lake
Water quality, depth, fish species, and recreation comparison.
Franklin Lake reads lower on nutrients and algae than Kentuck Lake. Both are in Wisconsin.
Franklin Lake and Kentuck 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 sit close on their nutrient and algae readings, Franklin Lake versus Kentuck Lake. The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.
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.

| Public Access | Yes | Yes |
| Fish Species | 5 | 5 |
| Trophic State | oligotrophic | 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.
