The extravagantly wet winter notwithstanding, California’s water woes are far from over. But recent moves suggest Governor Gavin Newsom is leading the state into a new era of water policy. Last month, he decided to scale back his predecessor’s decades-long effort, the Twin Tunnels, to deliver water from Northern to Southern California.
“Really, the idea that two massive tunnels would be built in the Delta was always—well, a pipe dream,” says Peter Gleick.
This massive project, known as the California WaterFix, was promoted by Jerry Brown as the solution to the state’s agricultural and urban water insecurity and environmental degradation in the Sacramento/San Joaquin Delta. Conceived as two 35-mile-long, 40-foot-diameter pipes buried under the Delta, the Twin Tunnels would’ve incorporated a great deal of concrete, steel, and machinery to move tremendous quantities of water southward.

Ultimately, though, it was a bridge—or tunnel—too far, even for Brown. And UC Berkeley water experts generally agree Newsom’s move away from the WaterFix is a pragmatic one.
“Jerry really wanted that legacy project, but he overplayed his hand,” says Richard Walker, a Berkeley professor emeritus of geography who has written extensively on state infrastructure, water, and agricultural issues. “The WaterFix was clearly a relic of the past. It doesn’t accord with either the will of the people of California or the actual way that state water management is moving.”
“Really, the idea that two massive tunnels would be built in the Delta was always—well, a pipe dream,” says Peter Gleick, a UC Berkeley alum and the president emeritus of the Pacific Institute, a water-oriented think tank. “It was always clear that you could get far better results spending much less money by exploring other avenues.”
And that’s exactly what experts anticipate Newsom will do. By scaling back Brown’s all-encompassing megaproject, he appears to be moving towards what analysts call a “portfolio” approach—or multiple, integrated programs, including one smaller tunnel.
