Clearwater Lake vs Ham Lake
Water quality, depth, fish species, and recreation comparison.
Clearwater Lake has a higher water quality grade (A, Excellent) than Ham Lake (D, Poor). Both are in Lake County, Minnesota.
Both Clearwater Lake and Ham 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 Ham Lake (D). 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?

Side-by-Side Metrics
| Metric | Clearwater Lake | Ham Lake |
|---|---|---|
| Overall Grade | A (Excellent) | D (Poor) |
| Water Clarity | 18 ft | 6 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 46 ft | 53 ft |
| Surface Area | 640.18 acres | 1.5K acres |
| Public Access | No | No |
| Fish Species | 0 | 0 |
| 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 Ham Lake's Grade D. Water clarity: 18 ft vs 6 ft. For fishing diversity, Clearwater Lake also leads with 0 species.
