Clearwater Lake vs Serpent Lake
Water quality, depth, fish species, and recreation comparison.
Serpent Lake reads lower on nutrients and algae than Clearwater Lake. Both are in Crow Wing County, Minnesota.
Clearwater Lake and Serpent 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 readings are close: Clearwater Lake and Serpent 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.
Serpent Lake
Crystal clear, you can see 25 ft down.
Side-by-Side Metrics
| Metric | Clearwater Lake | Serpent Lake |
|---|---|---|
| Water Clarity | 13 ft | 25 ft Better |
| Phosphorus | 12 µg/L | 12 µg/L |
| Chlorophyll-a (Algae) | 3.7 µg/L | 1.6 µg/L Better |
| Maximum Depth | 54 ft | 65 ft Better |
| Surface Area | 905 acres | 1,116 acres |
| Public Access | Yes | Yes |
| Fish Species | 16 | 17 Better |
| Trophic State | mesotrophic | oligotrophic |
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.
