Minong Flowage Lake vs Stone Lake
Water quality, depth, fish species, and recreation comparison.
Stone Lake has a higher water quality grade (A, Excellent) than Minong Flowage Lake (C, Fair). Both are in Washburn County, Wisconsin.
Both Minong Flowage Lake and Stone 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. Stone Lake (A) is materially cleaner than Minong Flowage Lake (C). 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 — Stone 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?

Side-by-Side Metrics
| Metric | Minong Flowage Lake | Stone Lake |
|---|---|---|
| Overall Grade | C (Fair) | A (Excellent) |
| Water Clarity | 3.5 ft | 23 ft |
| Phosphorus | 37.2 µg/L | 10.8 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 21 ft | 49 ft |
