Island Lake vs Toad Lake
Water quality, depth, fish species, and recreation comparison.
Island Lake has a higher water quality grade (B, Good) than Toad Lake (B, Good). Both are in Becker County, Minnesota.
Both Island Lake and Toad 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. These two are within a letter of each other on the rubric — Island Lake (B) versus Toad Lake (B). The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.
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.
Island Lake
Good clarity, visible to about 14.6 ft.

Side-by-Side Metrics
| Metric | Island Lake | Toad Lake |
|---|---|---|
| Overall Grade | B (Good) | B (Good) |
| Water Clarity | 14.6 ft | 7 ft |
| Phosphorus | 20 µg/L | 27 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 38 ft | 29 ft |
| Surface Area | 1.2K acres | 1.7K acres |
| Public Access | Yes | Yes |
| Fish Species | 1 | 1 |
| Trophic State | mesotrophic | eutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Island Lake wins on overall water quality with a Grade B versus Toad Lake's Grade B. Water clarity: 14.6 ft vs 7 ft. For fishing diversity, Island Lake also leads with 1 species.
