The current licensed South SWP Hydropower consists of two developments: Warne Power Development and Castaic Power Development, which are both located along the West Branch of the State Water Project (SWP) in Los Angeles County. DWR operates and manages all existing Project facilities in the Warne Power Development, and upstream of the Angeles Tunnel Surge Chamber in the Castaic Power Development. LADWP operates and manages the Surge Chamber and all existing Project facilities downstream of the Surge Chamber, in the Castaic Power development.
The new South SWP Hydropower license would include the following existing facilities, which are located between the towns of Castaic and Gorman, near Interstate 5, and approximately 17 to 34 miles northwest of the City of Los Angeles: Quail Lake and Embankment; Lower Quail Canal; Peace Valley Pipeline Intake and Embankment; Gorman Bypass Channel; William E. Warne Powerplant and Switchyard; Pyramid Dam; Pyramid Lake; Angeles Tunnel and Surge Chamber; Castaic Penstocks; Castaic Powerplant and Switchyard; Elderberry Dam and Forebay; Castaic Transmission Line; and recreation facilities at Quail Lake and Pyramid Lake.
The South SWP Hydropower FLA describes existing Project facilities, Project operation, estimated costs related to continued operations, general information, and the changes DWR and LADWP propose to the existing Project under the new license. In addition, the FLA describes environmental and recreational resources in the vicinity of the Project; an assessment of potential adverse environmental impacts associated with continued operation and maintenance of the Project as proposed by DWR and LADWP in the FLA; and DWR’s and LADWP’s proposed resource management measures for inclusion in the new license to protect and enhance environmental and recreation resources, and mitigate any Project impacts.
