Big Wolf Lake vs Wolf Lake
Water quality, depth, fish species, and recreation comparison.
Wolf Lake has a higher water quality grade (A, Excellent) than Big Wolf Lake (B, Good). Both are in Minnesota.
Both Big Wolf Lake and Wolf 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: Big Wolf Lake (B) and Wolf 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.
Big Wolf Lake
Good clarity, visible to about 11.5 ft.
Wolf Lake
Moderate clarity, visible to about 9 ft.
Side-by-Side Metrics
| Metric | Big Wolf Lake | Wolf Lake |
|---|---|---|
| Overall Grade | B (Good) | A (Excellent) |
| Water Clarity | 11.5 ft | 9 ft |
| Phosphorus | 21 µg/L | 19 µg/L |
| Chlorophyll-a (Algae) | No data | 5.3 µg/L |
| Maximum Depth | 57 ft | 57 ft |
| Surface Area | 1,076 acres | 1,076 acres |
| Public Access | Yes | Yes |
| Fish Species | 18 | 18 |
| Trophic State | mesotrophic | mesotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Wolf Lake wins on overall water quality with a Grade A versus Big Wolf Lake's Grade B. Water clarity: 9 ft vs 11.5 ft. For fishing diversity, Wolf Lake also leads with 18 species.
