Butternut Lake vs Pickerel Lake
Water quality, depth, fish species, and recreation comparison.
Butternut Lake and Pickerel Lake read the same on nutrients and algae. Both are in Forest County, Wisconsin.
Both Butternut Lake and Pickerel Lake sit in Wisconsin. A same-state comparison strips out the state-level water-quality regime as a variable: any differences in the readings here are about the lakes themselves, not the agencies sampling them. These two sit close on the readings, Butternut Lake versus Pickerel Lake. The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.
With readings 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.
Butternut Lake
Crystal clear, you can see 19.5 ft down.
Pickerel Lake
Good clarity, visible to about 10 ft.
Side-by-Side Metrics
| Metric | Butternut Lake | Pickerel Lake |
|---|---|---|
| Water Clarity | 19.5 ft Better | 10 ft |
| Phosphorus | 12.1 µg/L Better | 20.4 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 42 ft Better | 19 ft |
| Surface Area | 1,246 acres | 1,272 acres |
| Public Access | Yes | Yes |
| Fish Species | 4 | 4 |
| Trophic State | oligotrophic | mesotrophic |
A green ✓ marks the better value for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better). Surface area and trophic state carry no tick — a bigger lake is not a better lake.

Verdict
Both lakes earn the same Grade B. The tiebreakers come down to clarity (Butternut Lake: 19.5 ft, Pickerel Lake: 10 ft) and what you want from the lake. Butternut Lake matches its peer on species count.
