The Marin Independent Journal reports the proposed plan would deliver water from the Yuba River more than 100 miles before pumping it over the bridge into Marin County. The operation would also involve the cooperation of the East Bay Municipal District and the Contra Costa Water District in transferring and storing water destined for Marin. The proposed eight-mile long pipeline would cost an estimated $100 million to construct. There has been opposition to the pipeline from some elected officials. Conservationists have filed suit to block the project.
