Greenwood Lake vs Pine Lake
Water quality, depth, fish species, and recreation comparison.
Pine Lake has a higher water quality grade (A, Excellent) than Greenwood Lake (A, Excellent). Both are in Cook County, Minnesota.
Greenwood Lake and Pine 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: Greenwood Lake (A) and Pine 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.
Greenwood Lake
Good clarity, visible to about 14.8 ft.
Pine Lake

Side-by-Side Metrics
| Metric | Greenwood Lake | Pine Lake |
|---|---|---|
| Overall Grade | A (Excellent) | A (Excellent) |
| Water Clarity | 14.8 ft | 18 ft |
| Phosphorus | 8 µg/L | No data |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 112 ft | 113 ft |
| Surface Area | 2.0K acres | 2.1K acres |
| Public Access | Yes | No |
| Fish Species | 1 | 1 |
