Title

Rector Reservoir Bypass Valve Project

Description

CalVet operates Rector Dam and Reservoir to supply drinking water to the Veterans Home of California in Yountville, the Napa State Hospital, the California Department of Fish and Wildlife’s (CDFW) Bay-Delta Region office, the Town of Yountville, and several local wineries. CalVet also supplies untreated water to the CDFW Silverado Fisheries Base located along Rector Creek downstream of the dam, and to the California Department of Forestry and Fire Protection (CAL FIRE) training facility, located at the base of Rector Dam. The State Water Resources Control Board license to operate Rector Dam does not include specific instream flow release requirements to Rector Creek; however, California Fish and Game Code 5937 requires the owner or operator of any dam to allow sufficient flow to pass through or over the dam to keep fish downstream of the dam in good condition. The proposed Project addressed in the DEIR would implement an interim schedule for minimum environmental releases to Rector Creek below Rector Dam to meet Code 5937 requirements. To facilitate these releases, CalVet proposes to construct new facilities below Rector Dam to convey, monitor and release stored water from the reservoir to Rector Creek. Project facilities to be constructed include a bypass valve, 12-inch-diameter water pipeline, Rector Creek outfall structure, underground electrical/communications conduit, and Rector Creek erosion control measures. Specifically, the key components of the proposed Project include the following: -Diversion pipeline to convey water from the existing 30-inch water line at the base of Rector Dam to the proposed bypass valve and from the bypass valve to Rector Creek; -Bypass valve and flow meter; -Underground electrical and communications line and conduit between the bypass valve and CalVet Water Treatment Plant; -Twelve-inch-diameter underground water pipeline between the bypass valve and proposed Rector Creek outfall; and -Rector Creek outfall structure at the terminal end of that pipeline in Rector Creek and streambank erosion controls.
