Sherwood Lake Nr. Dam vs Sugar Hollow Lake

Water quality, depth, fish species, and recreation comparison.

Sherwood Lake Nr. Dam has a higher water quality grade (B, Good) than Sugar Hollow Lake (D, Poor). Both are in Warren County, Wisconsin.

Both Sherwood Lake Nr. Dam and Sugar Hollow Lake sit in Missouri. 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. Sherwood Lake Nr. Dam (B) is materially cleaner than Sugar Hollow Lake (D). 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 — Sherwood Lake Nr. Dam 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?

B

D
