Collinwood Lake vs Jennie Lake
Water quality, depth, fish species, and recreation comparison.
Jennie Lake reads lower on nutrients and algae than Collinwood Lake. Both are in Minnesota.
Both Collinwood Lake and Jennie 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: Collinwood Lake and Jennie 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.

Side-by-Side Metrics
| Metric | Collinwood Lake | Jennie Lake |
|---|---|---|
| Water Clarity | 4 ft Better | 3.9 ft |
| Phosphorus | 135 µg/L | 62 µg/L Better |
| Chlorophyll-a (Algae) | 38.6 µg/L | 24.3 µg/L Better |
| Maximum Depth | 28 ft Better | 15 ft |
| Surface Area | 639 acres | 1,069 acres |
| Public Access | Yes | Yes |
| Fish Species | 18 Better | 12 |
| Trophic State | eutrophic | 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.
