Elderberry Forebay is a small reservoir in Los Angeles County, California , which serves as the pumping forebay of the Castaic Power Plant. It located at the upper end of the larger Castaic Lake and is separated from the lake by Elderberry Forebay Dam at its southern edge. Entering the northern end of the forebay is the west branch of the California Aqueduct, which connects the forebay to Pyramid Lake through the Angeles Tunnel.[2][3]
A component of the California State Water Project, the reservoir was partitioned from Castaic Lake in 1974 to store water for pumped-storage hydroelectricity generation.[2][3] During on-peak energy-demand hours, water flows 7.5 miles (12.1 km) from Pyramid Lake through the Angeles Tunnel and then on to the turbines of the Castaic Power Plant, producing electricity. From there, the water flows into Elderberry Forebay. During off-peak hours (including nighttime and Sundays), water is pumped from the forebay, back through the tunnel and into Pyramid Lake.[3]
