Green Lake vs Silver Creek Estuary Lake
Water quality, depth, fish species, and recreation comparison.
Green Lake has a higher water quality grade (B, Good) than Silver Creek Estuary Lake (F, Very Poor). Both are in Green Lake County, Wisconsin.
Green Lake and Silver Creek Estuary 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 meaningfully apart: Green Lake grades a B while Silver Creek Estuary Lake grades a F. That two-letter spread reflects real underlying differences — different watershed inputs, different depth profiles, or different monitoring rigor.
For a recreational visitor, the wider grade gap is decisive — Green Lake is the better water-quality choice. For a researcher, the gap is the interesting part: what is different about the two watersheds, and which of those differences is mutable?

Side-by-Side Metrics
| Metric | Green Lake | Silver Creek Estuary Lake |
|---|---|---|
| Overall Grade | B (Good) | F (Very Poor) |
| Water Clarity | 13.1 ft | No data |
| Phosphorus | 23 µg/L | 122 µg/L |
| 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 |

Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Green Lake wins on overall water quality with a Grade B versus Silver Creek Estuary Lake's Grade F. For fishing diversity, Green Lake also leads with 0 species.
