Pelican Lake reads lower on nutrients and algae than Walker Lake. Both are in Otter Tail County, Minnesota.

Reviewed by LakeQuality Editorial Team · Updated

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?

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.

Verdict

Pelican Lake reads lower on nutrients and algae than Walker Lake. Water clarity: 16.4 ft vs 7.5 ft. For fishing diversity, Pelican Lake also leads with 20 species.
