California Code, Water Code - WAT § 85004

(a) The economies of major regions of the state depend on the ability to use water within the Delta watershed or to import water from the Delta watershed.  More than two-thirds of the residents of the state and more than two million acres of highly productive farmland receive water exported from the Delta watershed.

(b) Providing a more reliable water supply for the state involves implementation of water use efficiency and conservation projects, wastewater reclamation projects, desalination, and new and improved infrastructure, including water storage and Delta conveyance facilities.
