Welcome to the Hallwood Floodplain and Side Channel Restoration Project
A Habitat Enhancement Project on the lower Yuba River
This project will improve habitat in the lower Yuba River for Chinook salmon and steelhead trout. In an area mostly consisting of steep cobble embankments, the project has the potential to enhance or create up to 157 acres of seasonally-inundated riparian floodplain habitats, more than 1.7 miles of perennial side channels and alcoves, and more than 6.1 miles of seasonal side channels, alcoves, and swales.

- Non-native predatory fish (largemouth bass and sunfish) have been observed within the large backwater pool at the lower end of the Project reach.
- Rearing habitat quality dramatically alters residence time and survival of juvenile Chinook salmon.
- Individual predators may be having a disproportionately large effect.
