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.
Both Green Lake and Silver Creek Estuary 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. Green Lake (B) is materially cleaner than Silver Creek Estuary Lake (F). A gap that wide is unlikely to close in a single year of remediation work; it reflects multi-decade differences in the lakes themselves.
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 | No data | No data |
| Phosphorus | 20.6 µg/L | 122 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | - | 236 ft |

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.
