Hannen Lake vs Kent Park Lake
Water quality, depth, fish species, and recreation comparison.
Kent Park Lake has a higher water quality grade (C, Fair) than Hannen Lake (F, Very Poor). Both are in Wisconsin.
Both Hannen Lake and Kent Park Lake sit in Iowa. A same-state comparison strips out the state-level water-quality regime as a variable: any grade differences here are about the lakes themselves, not the agencies grading them. Kent Park Lake (C) is materially cleaner than Hannen Lake (F). A gap that wide is unlikely to close in a single year of remediation work; it reflects multi-decade differences in the lakes themselves.
For a recreational visitor, the wider grade gap is decisive — Kent Park 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?
Hannen Lake
Very murky, less than 1.2 ft of visibility.
Kent Park Lake

Side-by-Side Metrics
| Metric | Hannen Lake | Kent Park Lake |
|---|---|---|
| Overall Grade | F (Very Poor) | C (Fair) |
| Water Clarity | 1.2 ft | 4.8 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | 119.9 µg/L | 11.8 µg/L |
| Maximum Depth | - | - |
| Surface Area | 39 acres | 28.7 acres |

Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Kent Park Lake wins on overall water quality with a Grade C versus Hannen Lake's Grade F. Water clarity: 4.8 ft vs 1.2 ft. For fishing diversity, Kent Park Lake also leads with 0 species.
