Gov. Jerry Brown’s cheerleading squad was in high-spirited form Friday with the latest news that his twin tunnels project in the delta inched a step closer to reality. The state Department of Water Resources gave its approval to the tunnels by certifying the environmental reviews for the project. And really, what did you expect? The DWR answers to Brown, and Brown wants to build those four-story tunnels to funnel north state water from the Sacramento River, under the Sacramento-San Joaquin Delta, to farmers and cities in the south.
