A last-minute effort to require more state oversight of a company’s plan to pump water from underneath the Mojave Desert passed a key committee Tuesday, advancing in the final days of the legislative session. U.S. Sen. Dianne Feinstein, Gov. Jerry Brown and Lt. Gov. Gavin Newsom, who is running for governor, all urged lawmakers to pass it. At issue is a proposal by the Los Angeles-based Cadiz Inc. to pump water from its wells below the Mojave Desert, transfer it through a 43-mile pipeline to the Colorado River Aqueduct and distribute it to customers in Southern California.
