Green Lake vs Green Lake
Water quality, depth, fish species, and recreation comparison.
Green Lake and Green Lake both received the same overall water quality grade of B (Good). Both are in Green Lake County, Wisconsin.
Both Green Lake and Green Lake sit in Wisconsin. A same-state comparison strips out the state-level water-quality regime as a variable: any grade differences here are about the lakes themselves, not the agencies grading them. The grades are close: Green Lake (B) and Green 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.
Green Lake
Good clarity, visible to about 13.1 ft.
Green Lake
Good clarity, visible to about 13 ft.
Side-by-Side Metrics
| Metric | Green Lake | Green Lake |
|---|---|---|
| Overall Grade | B (Good) | B (Good) |
| Water Clarity | 13.1 ft | 13 ft |
| Phosphorus | 23 µg/L | No data |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 236 ft | 236 ft |
| Surface Area | 7.9K acres | 7.9K acres |
| Public Access | Unknown | Unknown |
| Fish Species | 0 | 0 |
| Trophic State | mesotrophic | mesotrophic |
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 (Green Lake: 13.1 ft, Green Lake: 13 ft) and what you want from the lake. Green Lake matches its peer on species count.
