Construction of east Branch Extension is in progres.

East Branch Extension

In April 1999, DWR began construction on the East Branch Extension, which will deliver water from Devil Canyon Powerplant's Afterbay to Yucaipa Valley and the San Gorgonio Pass area in San Bernardino and Riverside counties. The $77 million project— consisting of 13 miles of buried pipeline, three pump stations, and a 90 acre-foot regulatory reservoir—will meet the region's water needs for the next 40 years. SWP water will be used to recharge overdrafted groundwater basins and allow more flexibility for local water systems.

Scheduled for completion in 2001, the extension is a cooperative project between DWR, the San Bernardino Valley Municipal Water District, and the San Gorgonio Pass Water Agency. The two contractors will pay for the project's construction costs by repaying the principal and interest of revenue bonds sold to finance the project.
