FREMONT WEIR ADULT FISH PASSAGE MODIFICATION PROJECT Yolo Bypass, CA

FISH PASSAGE IMPROVEMENTS

The Yolo Bypass, a prominent feature of California’s State Plan of Flood Control, is a known adult fish anadromous migration RESTORATION GOAL / TARGET corridor. Currently, structures within the Yolo Bypass are a Improve adult fish passage at the Fremont Weir and documented source of migratory delay to, and loss of, special along the Tule Canal status species, including adult Chinook salmon, steelhead, and green sturgeon. Specifically, potential barriers exist for LOCATION AND LANDOWNER the migratory fish in the form of earthen agricultural road The site is located in the Upper Yolo Bypass. The Fremont crossings through the Tule Canal in the northern and mid-Yolo Weir is owned by the Sacramento-San Joaquin Drainage Bypass. The current fish ladder at the Fremont Weir provides District. The agricultural crossings are owned by Knaggs Ranch. insufficient passage for adult salmon and does not provide passage for adult sturgeon. Improved fish passage at Yolo FUNDING Bypass barriers (e.g. Fremont Weir) is necessary to enable open DWR and Reclamation water contractor funding with channel upstream migration to the , allowing support from Non-Governmental Organizations migrating fish to ultimately reach their spawning areas. TIMELINE The proposed Fremont Weir Adult Fish Passage Modification Project would widen and deepen the existing fish ladder at „„ Planning and Design - beginning 2016 the Fremont Weir. The maximum target flow through the fish passage structure would be limited to approximately 1,100 „„ Permitting - completed in 2017 cubic feet per second. The upstream and downstream adjoining channels would be reconfigured to accommodate migratory fish „„ Construction - 2018 passage. An existing earthen agricultural road crossings would be replaced by a permanent crossings, either railcar bridges PERMITTING or large fish-friendly box culverts, to allow for clear passage of migratory fish. One agricultural crossing would be eliminated. „„ All permits will be acquired before construction begins, including: The 2009 National Marine Fisheries Service (NMFS) Biological Opinion (BiOp) recognized the importance of floodplain „„ Endangered Species Act rearing habitat in, and fish passage throughout the Yolo Bypass. The 2009 BiOp requires the California Department of Water Resources (DWR) and U.S. Bureau of Reclamation „„ California Endangered Species Act, Section 2081 (Reclamation) to complete several projects, including habitat restoration and fish passage improvements in the Yolo Bypass. „„ Clean Water Act, Section 404 DWR and Reclamation, the lead agencies for CEQA/NEPA, are working closely with landowners to ensure the projects’ goals „„ Clean Water Act, Section 401, Water Quality Certification are met and current land uses will continue.
