Fox Lake vs Little Green Lake
Water quality, depth, fish species, and recreation comparison.
Fox Lake and Little Green Lake both received the same overall water quality grade of F (Very Poor). 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 grades are close: Fox Lake (F) and Little Green Lake (F) 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.
Fox Lake
Very murky, less than 1.7 ft of visibility.
Little Green Lake
Very murky, less than 2.9 ft of visibility.
Side-by-Side Metrics
| Metric | Fox Lake | Little Green Lake |
|---|---|---|
| Overall Grade | F (Very Poor) | F (Very Poor) |
| Water Clarity | 1.7 ft | 2.9 ft |
| Phosphorus | 106 µg/L | 97.6 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 19 ft | 28 ft |
| Surface Area | 2.7K acres | 462 acres |
| Public Access | Unknown | Unknown |
| Fish Species | 0 | 0 |
| Trophic State | hypereutrophic | eutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Both lakes earn the same Grade F. The tiebreakers come down to clarity (Fox Lake: 1.7 ft, Little Green Lake: 2.9 ft) and what you want from the lake. Fox Lake matches its peer on species count.
