Clear Lake vs Minnie-Belle Lake
Water quality, depth, fish species, and recreation comparison.
Minnie-Belle Lake has a higher water quality grade (A, Excellent) than Clear Lake (F, Very Poor). Both are in Meeker County, Minnesota.
Both Clear Lake and Minnie-Belle Lake sit in Minnesota. 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. Minnie-Belle Lake (A) is materially cleaner than Clear 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 — Minnie-Belle 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?
Clear Lake
Very murky, less than 3 ft of visibility.
Minnie-Belle Lake
Good clarity, visible to about 14.4 ft.
Side-by-Side Metrics
| Metric | Clear Lake | Minnie-Belle Lake |
|---|---|---|
| Overall Grade | F (Very Poor) | A (Excellent) |
| Water Clarity | 3 ft | 14.4 ft |
| Phosphorus | 141.5 µg/L | 14 µg/L |
| Chlorophyll-a (Algae) | 78.8 µg/L | 3.8 µg/L |
| Maximum Depth | 18 ft | 49 ft |
| Surface Area | 529 acres | 597 acres |
| Public Access | Yes | Yes |
| Fish Species | 13 | 14 |
| Trophic State | hypereutrophic | mesotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Minnie-Belle Lake wins on overall water quality with a Grade A versus Clear Lake's Grade F. Water clarity: 14.4 ft vs 3 ft. For fishing diversity, Minnie-Belle Lake also leads with 14 species.
