Callaway Fork Lake vs Sherwood Lake

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

Sherwood Lake has a higher water quality grade (B, Good) than Callaway Fork Lake (D, Poor). Both are in Wisconsin.

Callaway Fork Lake and Sherwood Lake are both in Missouri — 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. Sherwood Lake (B) is materially cleaner than Callaway Fork 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 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?

D

Callaway Fork Lake

St. Charles County, Wisconsin

Very murky, less than 3.3 ft of visibility.

B

Sherwood Lake

Warren County, Wisconsin

Murky, only visible to about 4.9 ft.
