Amacoy Lake vs Island Lake
Water quality, depth, fish species, and recreation comparison.
Island Lake has a higher water quality grade (B, Good) than Amacoy Lake (C, Fair). Both are in Rusk County, Wisconsin.
Both Amacoy Lake and Island Lake sit in Wisconsin. 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 — Amacoy Lake (C) versus Island 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.
Amacoy Lake
Murky, only visible to about 4.5 ft.
Island Lake

Side-by-Side Metrics
| Metric | Amacoy Lake | Island Lake |
|---|---|---|
| Overall Grade | C (Fair) | B (Good) |
| Water Clarity | 4.5 ft | 7.7 ft |
| Phosphorus | 25.3 µg/L | 15.4 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | - | - |
| Surface Area | 278 acres | 1.2K acres |
| Public Access | Unknown | Unknown |
| Fish Species | 0 | 0 |
| Trophic State | eutrophic | mesotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
