New Bullards Bar Dam Secondary Spillway

New Bullards Bar Dam Secondary Spillway

Notice of Preparation for the intent to prepare an Environmental Impact Report, Notice of Completion for the preparation of a Notice of Preparation, and a Summary Form for Electronic Submittals. Yuba Water Agency (YWA) proposes to construct the New Bullards Bar Dam Secondary Spillway Project (project). The project site is located 35 miles northeast of the City of Marysville, near the intersection of Marysville Road and County Road 169 in unincorporated Yuba County, California. The Secondary Spillway would have a discharge capacity of 35,000 cubic-feet-per second and operate conjunctively with the Primary Spillway and New Colgate Powerhouse to meet the Dam’s overall target releases. The Secondary Spillway may be used during small- and medium-sized flood events to maintain the designated flood space as well as during larger floods to evacuate a portion of the conservation storage to manage flood flows. The project components include the Secondary Spillway facility, relocating a small segment of Marysville Road over the Secondary Spillway, relocating the existing Dam Overlook Observation Site, and developing a permanent disposal area for soil and rock excavated during construction. Project construction would occur over approximately 3 years and is currently anticipated to begin in 2023.
