California’s water supply is trending poorly. Unless we act now to transform how California manages its water — by passing an important bill that would update our approach — the state will soon lose some of its year-to-year supply.

By 2050, California is expected to lose between 4.6 and 9 million acre-feet of its annual water supply. In other words, by 2050 at the latest, Californians would lose access to a volume of water that is enough to supply 50-90% of all the state’s households — or to irrigate 17-33% of all the state’s farmland. Picture a volume of water as large as two Lake Shastas disappearing from the state’s water bank.
