Townsend Flowage Lake vs White Potato Lake
Water quality, depth, fish species, and recreation comparison.
Townsend Flowage Lake and White Potato Lake both received the same overall water quality grade of B (Good). Both are in Oconto County, Wisconsin.
Both Townsend Flowage Lake and White Potato 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 — Townsend Flowage Lake (B) versus White Potato 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.

Side-by-Side Metrics
| Metric | Townsend Flowage Lake | White Potato Lake |
|---|---|---|
| Overall Grade | B (Good) | B (Good) |
| Water Clarity | No data | 6.5 ft |
| Phosphorus | 14.3 µg/L | 17 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | - | 11 ft |
| Surface Area | 476 acres | 1,023 acres |
| Public Access | Yes | Yes |
| Fish Species | 0 | 5 |
| Trophic State | mesotrophic | mesotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Both lakes earn the same Grade B. The tiebreakers come down to what you want from the lake. Townsend Flowage Lake has fewer fish species than White Potato Lake.
