One of the most enduring myths of California water politics is that the Delta Tunnels promoted by the Jerry Brown and Donald Trump administrations are designed to divert Northern California water to “fill swimming pools” of “wealthy water wasters” in Southern California. In reality, 80 percent of northern California water exported south of the Delta goes to irrigate agribusiness operations in the Central Valley, while the rest goes to urban and industrial users, including those in Southern California who have made many successful efforts to reduce water use and recycle water.
