COACHELLA CANAL LINING AGREEMENT SIGNED
SACRAMENTO–The Department of Water Resources and the Metropolitan Water District of Southern California
have signed an agreement providing $74 million in state funding to MWD for lining the remained unlined portion of
the U.S. Bureau of Reclamation’s Coachella Canal with concrete, to reduce seepage losses.
The funding was authorized by 1998 State legislation intended to help implement measures in California’s Colorado
River Water Use Plan.
The plan, available at http://www.crb.ca.gov, describes actions California will take to reduce its use of Colorado
River water from historical levels of more than 5 million acre-feet annually to California’s basic interstate allocation
of 4.4 MAF acre-feet annually.
California has historically been able to use part of the water allocated to Nevada and Arizona, but those states are
now taking their full allocations.
In the absence of hydrologic conditions making surplus water available, MWD’s Colorado River water supplies
would be reduced by about half at the 4.4 MAF allocation level.
Recently adopted river operations criteria limit MWD’s risk of reduced supplies until 2006, by which time several
projects to help MWD offset the reduction in its Colorado River supplies are expected to be completed.

Lining the remainder of the Coachella Canal is estimated to save about 26,000 acre-feet per year of water now lost
to seepage. Part of the conserved water will additionally facilitate implementing the San Luis Rey Indian Water
Rights Settlement Act, as provided for in that 1988 federal legislation.
The Coachella Canal conveys Colorado River water from Imperial Valley into
