Pelican Lake vs Tamarac Lake
Water quality, depth, fish species, and recreation comparison.
Pelican Lake has a higher water quality grade (A, Excellent) than Tamarac Lake (C, Fair). Both are in Otter Tail County, Minnesota.
Pelican Lake and Tamarac 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. Pelican Lake (A) is materially cleaner than Tamarac Lake (C). 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 — Pelican 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 | Pelican Lake | Tamarac Lake |
|---|---|---|
| Overall Grade | A (Excellent) Better | C (Fair) |
| Water Clarity | 16.4 ft Better | 6.2 ft |
| Phosphorus | 15 µg/L Better | 33 µg/L |
| Chlorophyll-a (Algae) | 3 µg/L Better | 10.7 µg/L |
| Maximum Depth | 55 ft Better | 11 ft |
| Surface Area | 3,962 acres | 445 acres |
| Public Access | Yes | Yes |
| Fish Species | 20 Better | 11 |
| Trophic State | mesotrophic | eutrophic |
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.
