Sand Lake vs Stone Lake
Water quality, depth, fish species, and recreation comparison.
Sand Lake reads lower on nutrients and algae than Stone Lake. 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 sit close on the readings, Sand Lake versus Stone Lake. The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.
With readings 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 |
|---|---|---|
| Water Clarity | 10 ft | 23 ft Better |
| Phosphorus | 23.8 µg/L | 11.2 µg/L Better |
| Chlorophyll-a (Algae) | 4.1 µg/L | No data |
| Maximum Depth | 50 ft Better | 49 ft |
| Surface Area | 949 acres | 490 acres |
| Public Access | Yes | Yes |
| Fish Species | 6 Better | 5 |
| Trophic State | mesotrophic | oligotrophic |
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
Sand Lake reads lower on nutrients and algae than Stone Lake. Water clarity: 10 ft vs 23 ft. For fishing diversity, Sand Lake also leads with 6 species.
