East Battle Lake vs Peterson Lake
Water quality, depth, fish species, and recreation comparison.
East Battle Lake has a higher water quality grade (A, Excellent) than Peterson Lake (D, Poor). Both are in Otter Tail County, Minnesota.
East Battle Lake and Peterson 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. East Battle Lake (A) is materially cleaner than Peterson Lake (D). 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 — East Battle 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?
East Battle Lake
Good clarity, visible to about 13.1 ft.
Peterson Lake
Murky, only visible to about 5.9 ft.
Side-by-Side Metrics
| Metric | East Battle Lake | Peterson Lake |
|---|---|---|
| Overall Grade | A (Excellent) | D (Poor) |
| Water Clarity | 13.1 ft | 5.9 ft |
| Phosphorus | 12 µg/L | No data |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 87 ft | 69 ft |
| Surface Area | 2.0K acres | 2.5K acres |
| Public Access | Yes | Yes |
| Fish Species | 1 | 1 |
| Trophic State | mesotrophic | eutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
East Battle Lake wins on overall water quality with a Grade A versus Peterson Lake's Grade D. Water clarity: 13.1 ft vs 5.9 ft. For fishing diversity, East Battle Lake also leads with 1 species.
