California's interconnected water system is the world's largest, managing over {{convert|40000000|acre.ft|km3|lk=in}} of water per year, centered on six main systems of aqueducts and infrastructure projects.<ref>Hundley, N. (2001). The great thirst: Californians and water. Berkeley, Calif.: University of California Press.</ref> Water use and conservation in California is a politically divisive issue, as the state experiences periodic droughts and has to balance the demands of its large agricultural and urban sectors, especially in the arid southern portion of the state. The state's widespread redistribution of water also invites the frequent scorn of environmentalists.

The [[California Water Wars]], a conflict between Los Angeles and the Owens Valley over water rights, is one of the most well-known examples of the struggle to secure adequate water supplies.<ref>{{Cite book |last=Reisner, Marc |title=Cadillac Desert: The American West and its Disappearing Water |date=1993 |publisher=Penguin}}</ref> Former California Governor [[Arnold Schwarzenegger]] said: "We've been in crisis for quite some time because we're now 38{{spaces}}million people and not anymore 18{{spaces}}million people like we were in the late 60s. So it developed into a battle between environmentalists and farmers and between the south and the north and between rural and urban. And everyone has been fighting for the last four decades about water."<ref>"[http://www.cbsnews.com/2100-18560_162-6014897.html Why California Is Running Dry]". CBS News. December 27, 2009.</ref>
