Clearwater Lake vs Round Lake
Water quality, depth, fish species, and recreation comparison.
Clearwater Lake reads lower on nutrients and algae than Round Lake. Both are in Crow Wing County, Minnesota.
Both Clearwater Lake and Round Lake sit in Minnesota. A same-state comparison strips out the state-level water-quality regime as a variable: any differences in the readings here are about the lakes themselves, not the agencies sampling them. The readings are close: Clearwater Lake and Round Lake sit within a narrow band of each other on phosphorus, chlorophyll-a and clarity. The per-parameter table below shows where the small differences actually live.
With readings this close, the choice between the two lakes turns on non-water-quality factors: depth, fish species, public access, distance from home. The per-lake pages below cover all of those.
Clearwater Lake
Good clarity, visible to about 13 ft.
Round Lake
Good clarity, visible to about 13.5 ft.
Side-by-Side Metrics
| Metric | Clearwater Lake | Round Lake |
|---|---|---|
| Water Clarity | 13 ft | 13.5 ft Better |
| Phosphorus | 12 µg/L Better | 17 µg/L |
| Chlorophyll-a (Algae) | 3.7 µg/L | 2.7 µg/L Better |
| Maximum Depth | 54 ft Better | 51 ft |
| Surface Area | 905 acres | 1,650 acres |
| Public Access | Yes | Yes |
| Fish Species | 16 | 20 Better |
| Trophic State | mesotrophic | mesotrophic |
A green ✓ marks the better value for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better). Surface area and trophic state carry no tick — a bigger lake is not a better lake.
