Sand Lake vs Stone Lake
Water quality, depth, fish species, and recreation comparison.
Sand Lake has a higher water quality grade (A, Excellent) than Stone Lake (B, Good). Both are in Wisconsin.
Sand Lake and Stone Lake are both in Wisconsin — a same-state head-to-head where the comparison comes down to lake-specific differences in depth, watershed, and monitoring history rather than the broader state-level water-quality regime. These two are within a letter of each other on the rubric — Sand Lake (A) versus Stone 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.
Sand Lake
Good clarity, visible to about 10 ft.
Stone Lake
Crystal clear, you can see 23 ft down.
Side-by-Side Metrics
| Metric | Sand Lake | Stone Lake |
|---|---|---|
| Overall Grade | A (Excellent) | B (Good) |
| Water Clarity | 10 ft | 23 ft |
| Phosphorus | 23.8 µg/L | 11.2 µg/L |
| Chlorophyll-a (Algae) | 4.1 µg/L | No data |
| Maximum Depth | 50 ft | 49 ft |
| Surface Area | 949 acres | 490 acres |
| Public Access | Yes | Yes |
| Fish Species | 6 | 5 |
| Trophic State | mesotrophic | oligotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Sand Lake wins on overall water quality with a Grade A versus Stone Lake's Grade B. Water clarity: 10 ft vs 23 ft. For fishing diversity, Sand Lake also leads with 6 species.
