Dead Lake vs Pelican Lake
Water quality, depth, fish species, and recreation comparison.
Dead Lake and Pelican Lake both received the same overall water quality grade of A (Excellent). Both are in Otter Tail County, Minnesota.
Dead 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. The grades are close: Dead Lake (A) and Pelican Lake (A) are within one letter of each other on the LakeGrade rubric. The per-parameter sub-grades below will show where the small differences actually live.
With grades 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.
Dead Lake
Good clarity, visible to about 10.2 ft.
Pelican Lake
Crystal clear, you can see 16.4 ft down.
Side-by-Side Metrics
| Metric | Dead Lake | Pelican Lake |
|---|---|---|
| Overall Grade | A (Excellent) | A (Excellent) |
| Water Clarity | 10.2 ft | 16.4 ft |
| Phosphorus | 20 µg/L | 15 µg/L |
| Chlorophyll-a (Algae) | 5.8 µg/L | 3 µg/L |
| Maximum Depth | 65 ft | 55 ft |
| Surface Area | 7,546 acres | 3,962 acres |
| Public Access | Yes | Yes |
| Fish Species | 18 | 20 |
| Trophic State | mesotrophic | mesotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Both lakes earn the same Grade A. The tiebreakers come down to clarity (Dead Lake: 10.2 ft, Pelican Lake: 16.4 ft) and what you want from the lake. Dead Lake has fewer fish species than Pelican Lake.
