Eagle Lake vs Sybil Lake
Water quality, depth, fish species, and recreation comparison.
Eagle Lake and Sybil Lake both received the same overall water quality grade of A (Excellent). Both are in Otter Tail County, Minnesota.
Both Eagle Lake and Sybil Lake sit in Minnesota. A same-state comparison strips out the state-level water-quality regime as a variable: any grade differences here are about the lakes themselves, not the agencies grading them. The grades are close: Eagle Lake (A) and Sybil 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.

Side-by-Side Metrics
| Metric | Eagle Lake | Sybil Lake |
|---|---|---|
| Overall Grade | A (Excellent) | A (Excellent) |
| Water Clarity | 22.6 ft | 20 ft |
| Phosphorus | 5 µg/L | 9 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 46 ft | 74 ft |
| Surface Area | 907.4 acres | 682.86 acres |
| Public Access | Yes | Yes |
| Fish Species | 10 | 16 |
| Trophic State | oligotrophic | 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 (Eagle Lake: 22.6 ft, Sybil Lake: 20 ft) and what you want from the lake. Eagle Lake has fewer fish species than Sybil Lake.
