Big Wolf Lake vs Little Wolf Lake
Water quality, depth, fish species, and recreation comparison.
Big Wolf Lake reads lower on nutrients and algae than Little Wolf Lake. Both are in Minnesota.
Big Wolf Lake and Little Wolf 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 readings are close: Big Wolf Lake and Little Wolf Lake sit within a narrow band of each other on phosphorus, chlorophyll-a and clarity. The per-parameter table below shows where the small differences actually live.
With readings 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.
Little Wolf Lake
Moderate clarity, visible to about 7 ft.
Side-by-Side Metrics
| Metric | Big Wolf Lake | Little Wolf Lake |
|---|---|---|
| Water Clarity | 11.5 ft Better | 7 ft |
| Phosphorus | 21 µg/L Better | 26.5 µg/L |
| Chlorophyll-a (Algae) | No data | 12.7 µg/L |
| Maximum Depth | 57 ft Better | 24 ft |
| Surface Area | 1,076 acres | 525 acres |
| Public Access | Yes | Yes |
| Fish Species | 18 Better | 13 |
| Trophic State | mesotrophic | eutrophic |
A green ✓ marks the better value for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better). Surface area and trophic state carry no tick — a bigger lake is not a better lake.
