Big Pine Lake vs Little Pine Lake
Water quality, depth, fish species, and recreation comparison.
Big Pine Lake reads lower on nutrients and algae than Little Pine Lake. Both are in Otter Tail County, Minnesota.
Both Big Pine Lake and Little Pine Lake sit in Minnesota. A same-state comparison strips out the state-level water-quality regime as a variable: any differences in the readings here are about the lakes themselves, not the agencies sampling them. The readings are close: Big Pine Lake and Little Pine 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 Pine Lake
Moderate clarity, visible to about 8.7 ft.
Little Pine Lake

Side-by-Side Metrics
| Metric | Big Pine Lake | Little Pine Lake |
|---|---|---|
| Water Clarity | 8.7 ft | 9.5 ft Better |
| Phosphorus | 26 µg/L | 26 µg/L |
| Chlorophyll-a (Algae) | 8 µg/L Better | 10.1 µg/L |
| Maximum Depth | 76 ft Better | 63 ft |
| Surface Area | 4,728 acres | 2,080 acres |
| Public Access | Yes | Yes |
| Fish Species | 20 | 20 |
| Trophic State | mesotrophic | mesotrophic |
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.
