Milan Lake North vs Unionville Lake
Water quality, depth, fish species, and recreation comparison.
Milan Lake North has a higher water quality grade (B, Good) than Unionville Lake (F, Very Poor). Both are in Wisconsin.
Milan Lake North and Unionville Lake are both in Missouri — 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: Milan Lake North grades a B while Unionville Lake grades a F. 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 — Milan Lake North 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 | Milan Lake North | Unionville Lake |
|---|---|---|
| Overall Grade | B (Good) | F (Very Poor) |
| Water Clarity | No data | 1.6 ft |
| Phosphorus | 51.8 µg/L | 129.5 µg/L |
| Chlorophyll-a (Algae) | 7.8 µg/L | 57.5 µg/L |
| Maximum Depth | - | - |
| Surface Area | 15 acres | 75 acres |
| Public Access | Unknown | Unknown |
| Fish Species | 0 | 0 |
| Trophic State | eutrophic | hypereutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Milan Lake North wins on overall water quality with a Grade B versus Unionville Lake's Grade F. For fishing diversity, Milan Lake North also leads with 0 species.
