Happy Holler Lake vs Mozingo Lake
Water quality, depth, fish species, and recreation comparison.
Happy Holler Lake has a higher water quality grade (C, Fair) than Mozingo Lake (F, Very Poor). Both are in Wisconsin.
Happy Holler Lake and Mozingo 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. Happy Holler Lake (C) is materially cleaner than Mozingo 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 — Happy Holler 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 | Happy Holler Lake | Mozingo Lake |
|---|---|---|
| Overall Grade | C (Fair) | F (Very Poor) |
| Water Clarity | No data | No data |
| Phosphorus | 63 µg/L | 120 µg/L |
| Chlorophyll-a (Algae) | 12.7 µg/L | No data |
| Maximum Depth | - | - |
| Surface Area | 62 acres | 1.0K acres |
| Public Access | Unknown | Unknown |
| Fish Species | 0 | 0 |

Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Happy Holler Lake wins on overall water quality with a Grade C versus Mozingo Lake's Grade F. For fishing diversity, Happy Holler Lake also leads with 0 species.
