The Anadromous Fish Restoration Program (AFRP) aims to double the natural production of anadromous fish (who spend their adult life in oceans and return to rivers to reproduce) like Chinook salmon and steelhead. Under this program, the U.S. Fish and Wildlife Service (USFWS) funds the design and implementation of the Hallwood Project. The lower Yuba River can host up to 20% of all salmon spawning in the Sacramento River tributaries, but these emerging young fish face many challenges reaching the ocean. Thus, the Project’s primary focus 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.
