The Anadromous Fish Restoration Program aims to double the natural production of anadromous fish (fish that spend their adult life in oceans and return to the rivers to reproduce) like Chinook salmon and steelhead. The lower Yuba River can host up to 20 percent of all salmon spawning in the Sacramento River tributaries, but these emerging young fish face many challenges reaching the ocean. The primary focus of this project is to enhance productive juvenile salmonid rearing habitat, to allow juvenile fish to grow larger prior to their migration to the ocean, which will increase their chance of returning as adults. The U.S. Fish and Wildlife Service is funding the design and implementation of the Hallwood Project.
