Sissabagama Lake vs Stone Lake
Water quality, depth, fish species, and recreation comparison.
Sissabagama Lake and Stone Lake both received the same overall water quality grade of B (Good). Both are in Wisconsin.
Sissabagama 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. The grades are close: Sissabagama Lake (B) and Stone Lake (B) are within one letter of each other on the LakeGrade rubric. 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.
Sissabagama Lake
Moderate clarity, visible to about 8 ft.
Stone Lake
Crystal clear, you can see 23 ft down.
Side-by-Side Metrics
| Metric | Sissabagama Lake | Stone Lake |
|---|---|---|
| Overall Grade | B (Good) | B (Good) |
| Water Clarity | 8 ft | 23 ft |
| Phosphorus | 18.7 µg/L | 11.2 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 48 ft | 49 ft |
| Surface Area | 805 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
Both lakes earn the same Grade B. The tiebreakers come down to clarity (Sissabagama Lake: 8 ft, Stone Lake: 23 ft) and what you want from the lake. Sissabagama Lake supports more documented fish species.
