Fox Lake vs Little Green Lake
Water quality, depth, fish species, and recreation comparison.
Fox Lake and Little Green Lake read the same on nutrients and algae. Both are in Wisconsin.
Fox Lake and Little Green 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 readings are close: Fox Lake and Little Green Lake sit within a narrow band of each other on phosphorus, chlorophyll-a and clarity. The per-parameter table below shows where the small differences actually live.
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.
Fox Lake
Very murky, less than 2 ft of visibility.
Little Green Lake
Very murky, less than 3.2 ft of visibility.
Side-by-Side Metrics
| Metric | Fox Lake | Little Green Lake |
|---|---|---|
| Water Clarity | 2 ft | 3.2 ft Better |
| Phosphorus | 102.4 µg/L | 92.8 µg/L Better |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 19 ft | 28 ft Better |
| Surface Area | 2,713 acres | 462 acres |
| Public Access | Yes | Yes |
| Fish Species | 5 | 5 |
| 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 (Fox Lake: 2 ft, Little Green Lake: 3.2 ft) and what you want from the lake. Fox Lake matches its peer on species count.
