Channel Rehabilitation Site: Chapman Ranch Phase A

The TRRP, Bureau of Reclamation and Bureau of Land Management (federal co-lead agencies), and the North Coast Regional Water Quality Control Board (Regional Water Board – state lead agency) are constructing the Chapman Ranch Phase A project in 2019. The purpose of the project is to increase salmon and steelhead habitat downstream of Lewiston Dam. The project is designed to enhance both terrestrial and aquatic habitat quality. In-river work will increase habitat complexity via construction of slow water refuge habitats (e.g., side channels), re-connecting the river with its floodplains, and placement of in-river geomorphic and habitat features (e.g., rock and wood structures). On-shore work will include revegetation of riparian and upland areas with native vegetation.
