East Battle Lake vs Stuart Lake
Water quality, depth, fish species, and recreation comparison.
East Battle Lake and Stuart Lake both received the same overall water quality grade of A (Excellent). Both are in Otter Tail County, Minnesota.
East Battle Lake and Stuart 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: East Battle Lake (A) and Stuart 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.
East Battle Lake
Good clarity, visible to about 13.1 ft.
Stuart Lake
Crystal clear, you can see 17.5 ft down.
Side-by-Side Metrics
| Metric | East Battle Lake | Stuart Lake |
|---|---|---|
| Overall Grade | A (Excellent) | A (Excellent) |
| Water Clarity | 13.1 ft | 17.5 ft |
| Phosphorus | 12 µg/L | 12 µg/L |
| Chlorophyll-a (Algae) | 4.2 µg/L | 3.7 µg/L |
| Maximum Depth | 87 ft | 49 ft |
| Surface Area | 1,978 acres | 740 acres |
| Public Access | Yes | Yes |
| Fish Species | 16 | 14 |
| Trophic State | mesotrophic | oligotrophic |
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 (East Battle Lake: 13.1 ft, Stuart Lake: 17.5 ft) and what you want from the lake. East Battle Lake supports more documented fish species.
