Pelican Lake vs Walker Lake
Water quality, depth, fish species, and recreation comparison.
Pelican Lake reads lower on nutrients and algae than Walker Lake. Both are in Otter Tail County, Minnesota.
Pelican Lake and Walker 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 reads materially cleaner than Walker Lake on nutrients and algae. 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 gap in the readings is decisive: Pelican Lake has the lower nutrient and algae numbers. 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 | Walker Lake |
|---|---|---|
| Water Clarity | 16.4 ft Better | 7.5 ft |
| Phosphorus | 15 µg/L Better | 26.5 µg/L |
| Chlorophyll-a (Algae) | 3 µg/L Better | 8.3 µg/L |
| Maximum Depth | 55 ft Better | 29 ft |
| Surface Area | 3,962 acres | 578 acres |
| Public Access | Yes | Yes |
| Fish Species | 20 Better | 0 |
| 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.
