Since taking office Jan. 7, Gov. Gavin Newsom has not indicated how he intends to approach one of the state’s most pressing issues: water. Former Gov. Jerry Brown wasted eight years trying to force California to push through his misguided $19 billion Sacramento-San Joaquin Delta twin-tunnels scheme, which wouldn’t add a drop of new water to the state’s supply. It’s time to set a new course. Newsom should signal that it’s a new day in California water politics by embracing a more-sustainable water policy that emphasizes conservation and creation of vast supplies of renewable water.
