Clearwater Lake vs Rifle Lake
Water quality, depth, fish species, and recreation comparison.
Clearwater Lake has a higher water quality grade (A, Excellent) than Rifle Lake (D, Poor). Both are in Lake County, Minnesota.
Clearwater Lake and Rifle 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. The grades are meaningfully apart: Clearwater Lake grades a A while Rifle Lake grades a D. 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 — 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?

Side-by-Side Metrics
| Metric | Clearwater Lake | Rifle Lake |
|---|---|---|
| Overall Grade | A (Excellent) | D (Poor) |
| Water Clarity | 18 ft | 4.8 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 46 ft | 37 ft |
| Surface Area | 640.18 acres | 904.07 acres |
| Public Access | No | No |
| Fish Species | 0 | 1 |
| Trophic State | oligotrophic | eutrophic |
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 Rifle Lake's Grade D. Water clarity: 18 ft vs 4.8 ft. For more fish-species variety, Rifle Lake edges ahead with 1 documented species.
