Chequamegon Waters Flowage Lake vs Holcombe Flowage Lake
Water quality, depth, fish species, and recreation comparison.
Chequamegon Waters Flowage Lake and Holcombe Flowage Lake both received the same overall water quality grade of D (Nutrient-rich). Both are in Wisconsin.
Both Chequamegon Waters Flowage Lake and Holcombe Flowage 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. The grades are close: Chequamegon Waters Flowage Lake (D) and Holcombe Flowage Lake (D) are within one letter of each other on our A–F scale. The per-parameter sub-grades below will show where the small differences actually live.
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.
Chequamegon Waters Flowage Lake
Very murky, less than 2.5 ft of visibility.
Holcombe Flowage Lake
Murky, only visible to about 3.7 ft.
Side-by-Side Metrics
| Metric | Chequamegon Waters Flowage Lake | Holcombe Flowage Lake |
|---|---|---|
| Overall Grade | D (Nutrient-rich) | D (Nutrient-rich) |
| Water Clarity | 2.5 ft | 3.7 ft Better |
| Phosphorus | 91.3 µg/L | 49.6 µg/L Better |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 22 ft | - |
| Surface Area | 2,366 acres | 4,300 acres |
| Public Access | Yes | Yes |
| Fish Species | 3 Better | 0 |
| Trophic State | eutrophic | eutrophic |
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 D. The tiebreakers come down to clarity (Chequamegon Waters Flowage Lake: 2.5 ft, Holcombe Flowage Lake: 3.7 ft) and what you want from the lake. Chequamegon Waters Flowage Lake supports more documented fish species.
