Buffalo Lake vs Clearwater Lake
Water quality, depth, fish species, and recreation comparison.
Clearwater Lake has a higher water quality grade (A, Excellent) than Buffalo Lake (F, Very Poor). Both are in Wright County, Minnesota.
Both Buffalo Lake and Clearwater 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. Clearwater Lake (A) is materially cleaner than Buffalo 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 — Clearwater 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?
Buffalo Lake
Very murky, less than 3 ft of visibility.
Clearwater Lake
Moderate clarity, visible to about 9.8 ft.
Side-by-Side Metrics
| Metric | Buffalo Lake | Clearwater Lake |
|---|---|---|
| Overall Grade | F (Very Poor) | A (Excellent) |
| Water Clarity | 3 ft | 9.8 ft |
| Phosphorus | 47 µg/L | 22 µg/L |
| Chlorophyll-a (Algae) | 40.6 µg/L | 6.3 µg/L |
| Maximum Depth | 33 ft | 73 ft |
| Surface Area | 1,552 acres | 3,187 acres |
| Public Access | Yes | Yes |
| Fish Species | 20 | 17 |
| Trophic State | eutrophic | mesotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Clearwater Lake wins on overall water quality with a Grade A versus Buffalo Lake's Grade F. Water clarity: 9.8 ft vs 3 ft. For more fish-species variety, Buffalo Lake edges ahead with 20 documented species.
