Otter Tail Lake vs Pelican Lake
Water quality, depth, fish species, and recreation comparison.
Otter Tail Lake and Pelican Lake read the same on nutrients and algae. Both are in Otter Tail County, Minnesota.
Otter Tail Lake and Pelican 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. These two sit close on the readings, Otter Tail Lake versus Pelican Lake. The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.
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.
Otter Tail Lake
Good clarity, visible to about 12.1 ft.
Pelican Lake
Crystal clear, you can see 16.4 ft down.
Side-by-Side Metrics
| Metric | Otter Tail Lake | Pelican Lake |
|---|---|---|
| Water Clarity | 12.1 ft | 16.4 ft Better |
| Phosphorus | 16 µg/L | 15 µg/L Better |
| Chlorophyll-a (Algae) | 5.5 µg/L | 3 µg/L Better |
| Maximum Depth | 120 ft Better | 55 ft |
| Surface Area | 14,079 acres | 3,962 acres |
| Public Access | Yes | Yes |
| Fish Species | 17 | 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.
