Long Lake vs Stone Lake
Water quality, depth, fish species, and recreation comparison.
Stone Lake reads lower on nutrients and algae than Long Lake. Both are in Washburn County, Wisconsin.
Both Long Lake and Stone 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. The readings are close: Long Lake and Stone Lake sit within a narrow band of each other on phosphorus, chlorophyll-a and clarity. The per-parameter table below shows where the small differences actually live.
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.
Long Lake
Moderate clarity, visible to about 9.5 ft.
Stone Lake
Crystal clear, you can see 23 ft down.
Side-by-Side Metrics
| Metric | Long Lake | Stone Lake |
|---|---|---|
| Water Clarity | 9.5 ft | 23 ft Better |
| Phosphorus | 17.3 µg/L | 11.2 µg/L Better |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | - | 49 ft |
| Surface Area | 3,290 acres | 490 acres |
| Public Access | Yes | Yes |
| Fish Species | 0 | 5 Better |
| Trophic State | mesotrophic | oligotrophic |
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.
