Major Accomplishments: Delta-Mendota Canal/California Aqueduct Intertie Project
|The Delta-Mendota Canal and the California Aqueduct.|
Secretary of the Interior Ken Salazar led a groundbreaking ceremony in October 2010 for an integral link between the two Central Valley canals to improve water supply reliability south of the Sacramento-San Joaquin Delta.
Although the Delta-Mendota Canal/California Aqueduct Intertie project, at a cost of $28 million, may be considered relatively small compared to many other water infrastructure improvements, U.S. Senator Dianne Feinstein, Bureau of Reclamation Commissioner Mike Connor, and several other leaders attended the ceremony, emphasizing the project’s importance because it adds operational flexibility and more efficient use of a limited water supply in an area hard hit by dry conditions and loss of jobs. (See page 30 for all participants.)
Reclamation provided nearly $16 million in 2009 American Recovery and Reinvestment Act funds, which combined with other funding sources, made it possible to begin construction of the planned Intertie. Reclamation, the San Luis and Delta-Mendota Water Authority, and the California Department of Water Resources are partnering to construct the project.
The Intertie will potentially increase average annual deliveries to the Central Valley Project by as much as 35,000 acre-feet by addressing conveyance conditions in the Delta-Mendota Canal that restrict use of the C. W. “Bill” Jones Pumping Plant near Tracy to less than its design capacity. The link, via two 108-inch diameter pipelines that are 500-feet long, will allow more conveyance to storage south of the Delta, provide redundancy in the distribution system in case of emergency, and make maintenance and repair work less disruptive to water deliveries.

The Delta-Mendota Canal receives water pumped by the Jones plant and is the primary federal delivery facility sending water to Central Valley Project contractors south of the Delta. The State Water Project’s California Aqueduct operates in much the way.
A construction contract for the Intertie, in an unincorporated area of the San Joaquin Valley in Alameda County, west of the city of Tracy, was awarded to Shimmick Construction Co. of Oakland, Calif., in July 2010. The project will provide about 160 construction jobs and is expected to be completed in 2012.
