Devil Track Lake vs Two Island Lake
Water quality, depth, fish species, and recreation comparison.
Devil Track Lake and Two Island Lake both received the same overall water quality grade of A (Excellent). 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 grades are close: Devil Track Lake (A) and Two Island 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.
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 |
|---|---|---|
| Overall Grade | A (Excellent) | A (Excellent) |
| Water Clarity | 7 ft | 9 ft |
| Phosphorus | 12 µg/L | 12 µg/L |
| Chlorophyll-a (Algae) | 5.3 µg/L | 3.4 µg/L |
| Maximum Depth | 50 ft | 27 ft |
| Surface Area | 1,876 acres | 754 acres |
| Public Access | Yes | Yes |
| Fish Species | 9 | 7 |
| Trophic State | mesotrophic | mesotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
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.
