Devil Track Lake vs Two Island Lake
Water quality, depth, fish species, and recreation comparison.
Devil Track Lake and Two Island Lake read the same on nutrients and algae. Both are in Cook County, Minnesota.
Devil Track Lake and Two Island 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: Devil Track Lake and Two Island 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.
Devil Track Lake
Moderate clarity, visible to about 7 ft.
Two Island Lake
Moderate clarity, visible to about 9 ft.
Side-by-Side Metrics
| Metric | Devil Track Lake | Two Island Lake |
|---|---|---|
| Water Clarity | 7 ft | 9 ft Better |
| Phosphorus | 12 µg/L | 12 µg/L |
| Chlorophyll-a (Algae) | 5.3 µg/L | 3.4 µg/L Better |
| Maximum Depth | 50 ft Better | 27 ft |
| Surface Area | 1,876 acres | 754 acres |
| Public Access | Yes | Yes |
| Fish Species | 9 Better | 7 |
| 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.

Verdict
Both lakes earn the same Grade A. The tiebreakers come down to clarity (Devil Track Lake: 7 ft, Two Island Lake: 9 ft) and what you want from the lake. Devil Track Lake supports more documented fish species.
