Lake Puckaway vs Little Green Lake
Water quality, depth, fish species, and recreation comparison.
Lake Puckaway and Little Green Lake both received the same overall water quality grade of D (Poor). Both are in Green Lake County, Wisconsin.
Lake Puckaway 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: Lake Puckaway (D) and Little Green Lake (D) 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.
Lake Puckaway
Murky, only visible to about 4.4 ft.
Little Green Lake
Very murky, less than 3.2 ft of visibility.
Side-by-Side Metrics
| Metric | Lake Puckaway | Little Green Lake |
|---|---|---|
| Overall Grade | D (Poor) | D (Poor) |
| Water Clarity | 4.4 ft | 3.2 ft |
| Phosphorus | 52.1 µg/L | 92.8 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 5 ft | 28 ft |
| Surface Area | 5,013 acres | 462 acres |
| Public Access | Yes | Yes |
| Fish Species | 6 | 5 |
| Trophic State | eutrophic | eutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Both lakes earn the same Grade D. The tiebreakers come down to clarity (Lake Puckaway: 4.4 ft, Little Green Lake: 3.2 ft) and what you want from the lake. Lake Puckaway supports more documented fish species.
