Toad Lake vs Wolf Lake
Water quality, depth, fish species, and recreation comparison.
Toad Lake and Wolf Lake both received the same overall water quality grade of C (Fair). Both are in Becker County, Minnesota.
Both Toad Lake and Wolf Lake sit in Minnesota. A same-state comparison strips out the state-level water-quality regime as a variable: any grade differences here are about the lakes themselves, not the agencies grading them. The grades are close: Toad Lake (C) and Wolf Lake (C) 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.
Toad Lake
Moderate clarity, visible to about 7 ft.
Wolf Lake
Murky, only visible to about 3.9 ft.
Side-by-Side Metrics
| Metric | Toad Lake | Wolf Lake |
|---|---|---|
| Overall Grade | C (Fair) | C (Fair) |
| Water Clarity | 7 ft | 3.9 ft |
| Phosphorus | 27 µg/L | 25 µg/L |
| Chlorophyll-a (Algae) | 8 µg/L | 6.9 µg/L |
| Maximum Depth | 29 ft | 16 ft |
| Surface Area | 1,715 acres | 1,460 acres |
| Public Access | Yes | Yes |
| Fish Species | 15 | 11 |
| Trophic State | eutrophic | eutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Both lakes earn the same Grade C. The tiebreakers come down to clarity (Toad Lake: 7 ft, Wolf Lake: 3.9 ft) and what you want from the lake. Toad Lake supports more documented fish species.
