Amacoy Lake vs Dairyland Reservoir
Water quality, depth, fish species, and recreation comparison.
Amacoy Lake has a higher water quality grade (C, Fair) than Dairyland Reservoir (F, Very Poor). Both are in Rusk County, Wisconsin.
Both Amacoy Lake and Dairyland Reservoir 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. Amacoy Lake (C) is materially cleaner than Dairyland Reservoir (F). A gap that wide is unlikely to close in a single year of remediation work; it reflects multi-decade differences in the lakes themselves.
For a recreational visitor, the wider grade gap is decisive — Amacoy Lake is the better water-quality choice. For a researcher, the gap is the interesting part: what is different about the two watersheds, and which of those differences is mutable?
Amacoy Lake
Murky, only visible to about 4.5 ft.
Dairyland Reservoir
Very murky, less than 1.4 ft of visibility.
Side-by-Side Metrics
| Metric | Amacoy Lake | Dairyland Reservoir |
|---|---|---|
| Overall Grade | C (Fair) | F (Very Poor) |
| Water Clarity | 4.5 ft | 1.4 ft |
| Phosphorus | 25.3 µg/L | No data |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | - | - |
| Surface Area | 278 acres | 2.0K acres |
| Public Access | Unknown | Unknown |
| Fish Species | 0 | 0 |
| Trophic State | eutrophic | hypereutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Amacoy Lake wins on overall water quality with a Grade C versus Dairyland Reservoir's Grade F. Water clarity: 4.5 ft vs 1.4 ft. For fishing diversity, Amacoy Lake also leads with 0 species.
