Allie Lake vs Belle Lake
Water quality, depth, fish species, and recreation comparison.
Belle Lake has a higher water quality grade (C, Fair) than Allie Lake (F, Very Poor). Both are in Minnesota.
Allie Lake and Belle Lake are both in Minnesota — 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. Belle Lake (C) is materially cleaner than Allie 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 — 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?
Allie Lake
Very murky, less than 2 ft of visibility.
Belle Lake
Murky, only visible to about 3.9 ft.
Side-by-Side Metrics
| Metric | Allie Lake | Belle Lake |
|---|---|---|
| Overall Grade | F (Very Poor) | C (Fair) |
| Water Clarity | 2 ft | 3.9 ft |
| Phosphorus | 232 µg/L | 42 µg/L |
| Chlorophyll-a (Algae) | 98.3 µg/L | No data |
| Maximum Depth | 12 ft | 25 ft |
| Surface Area | 509.13 acres | 863.92 acres |
| Public Access | Yes | Yes |
| Fish Species | 1 | 1 |
| Trophic State | hypereutrophic | eutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Belle Lake wins on overall water quality with a Grade C versus Allie Lake's Grade F. Water clarity: 3.9 ft vs 2 ft. For fishing diversity, Belle Lake also leads with 1 species.
