Big Lake vs White Sand Lake Deep
Water quality, depth, fish species, and recreation comparison.
White Sand Lake Deep has a higher water quality grade (A, Excellent) than Big Lake (C, Fair). Both are in Vilas County, Wisconsin.
Both Big Lake and White Sand Lake Deep 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. White Sand Lake Deep (A) is materially cleaner than Big 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 — White Sand Lake Deep 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?
Big Lake
Moderate clarity, visible to about 7 ft.
White Sand Lake Deep

Side-by-Side Metrics
| Metric | Big Lake | White Sand Lake Deep |
|---|---|---|
| Overall Grade | C (Fair) | A (Excellent) |
| Water Clarity | 7 ft | 18 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 30 ft | 63 ft |
| Surface Area | 780 acres | 1.2K acres |
| Public Access | Unknown | Unknown |
| Fish Species | 0 | 0 |

Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
White Sand Lake Deep wins on overall water quality with a Grade A versus Big Lake's Grade C. Water clarity: 18 ft vs 7 ft. For fishing diversity, White Sand Lake Deep also leads with 0 species.
