FRESNO, Calif. (AP) – California must now decide what’s next for upgrading its water delivery system after a key player rejected Gov. Jerry Brown’s plans to build two giant tunnels. All sides of California’s water war agree the north-south system needs a major overhaul. The powerful Westlands Water District dealt a major blow to the project when it opted out, saying the $16 billion tunnels were too expensive. University of California, Davis, professor Jay Lund says the “no” vote by the group of farmers creates an opening for robust political dialogue on California water. He says water is so vital that somebody will always be advancing projects. Another key group, Metropolitan Water District, isn’t sure what’s next. Jeffrey Kightlinger of the district, says a scaled-back version of the tunnels is a good starting point.
