Yolo Bypass Habitat Restoration Program

In 2012, DWR and the U.S. Bureau of Reclamation (Reclamation) began planning the Yolo Bypass Salmonid Habitat Restoration and Fish Passage (YBSHRFP) project, a suite of restoration actions under DWR’s Yolo Bypass Habitat Restoration Program. The need for the project was to remain in compliance with the Endangered Species Act, by carrying out Actions 1.61 and 1.7, as described in the National Marine Fisheries Service (NMFS) BO and the 2012 Yolo Bypass Salmonid Habitat Restoration and Fish Passage Implementation Plan (PDF, 2.6 MB) prepared by Reclamation and DWR. The Implementation Plan was reviewed and accepted by NMFS. It provides details on biological objectives, performance measures, potential fish passage actions, and a brief overview of planning, coordination and regulatory compliance efforts. Both physical and operational modifications were to be included in efforts to increase seasonal inundation and improve fish passage.

Pursuant to the California Environmental Quality Act, a Notice of Preparation of an Environmental Impact Statement/Environmental Impact Report (EIS/EIR) on the YBSHRFP project was circulated for an extended public comment period in 2013. Two public scoping meetings were held in 2013 to inform interested parties about the proposed project, and to solicit agency and public input on the scope and content of the EIS/EIR.

In 2015, five separate Yolo Bypass BO projects were identified from the original YBSHRFP suite of projects and were included in California EcoRestore. These projects include the following: YBSHRFP, Fremont Weir Adult Fish Passage Modification Project, Wallace Weir Fish Rescue Facility Project, Lower Putah Creek Restoration Project, and Lisbon Weir Fish Passage Project. Under the purview of California EcoRestore, all of these projects were given specific accelerated construction timelines, except for YBSHRFP. See below for descriptions of the five projects.
