Our View: Bay Delta Conservation Plan doesn’t consider tunnel alternatives

Despite the state’s 34,000-page draft environmental impact study, fundamental questions remain unanswered about the proposal to build two huge tunnels to divert water from the Sacramento-San Joaquin River Delta to points south.
The basic financial framework, for example, remains unresolved. Yet to be determined is how the multibillion-dollar cost would be split among water agencies that would benefit, and the state and federal governments. What would be the role be of the Delta counties, such as San Joaquin and Sacramento?
The report also fails to define how much water would actually flow through the Delta.
The first critical indication whether the twin-tunnel idea has legs will be hard commitments from the water agencies for ponying up the $1.2 billion to complete the pre-construction planning – from big agricultural water contractors, such as the Westlands Water District and the Kern County Water Agency, and the big urban water contractors, including the Metropolitan Water District of Southern California and the Santa Clara Valley Water District. Without such commitments even before the public comment period is done in April, all parties should rethink the project.
According to the Bay Delta Conservation Plan, the twin tunnels would not divert more water from the Delta than is currently permitted. The BDCP anticipates that “annual water diversions from the Delta would be within 10 percent of the historic, 20-year average.”
This conversation takes place when the first 10 months of the year were the driest since 1895, according to the National Climatic Data Center. The U.S. Drought Monitor estimates that 83 percent of the state is in severe drought. And we face longer-term climate issues that very likely will alter the volume and timing of spring runoff.
Scott Stine of California State University, East Bay, has found that the last century and a half was abnormally wet for the last 4,000 years, and that “drier times undoubtedly lie ahead.”
Water contractors’ hopes of exporting 4.8 million to 5.8 million acre-feet of water south, as in the last 20 years, might be unrealistic.
Are state officials and water contractors open to looking at a smaller project – plus reducing water demand and increasing storage south of the Delta? One option is a single 3,000 cubic-feet-per-second tunnel, with exports of 4 million acre-feet in an average year.
Many will perceive this as an old-fashioned water grab. And they won’t give up without a fight. It is time to seriously consider alternatives, something the 34,000-page draft study just doesn’t do.
