The Sacramento–San Joaquin Delta is a major source of water for cities and farms across the state, and a major source of water conflict. In a Sacramento Bee commentary two years ago, we and our colleague Brian Gray promoted a grand compromise for the Delta. We suggested that the three broad interests fighting about its future—water users, environmental groups, and Delta residents—give up something in order to reduce conflict and make progress. During his first state of the state address, Gov. Gavin Newsom opened the door to just such a compromise.
