California: Central Valley Aquifer Study Posted: 20 Nov 2010 09:53 PM PST “California's Central Valley covers about 20,000 square miles and is one of the most productive agricultural regions in the world.

This irrigated agriculture relies heavily on surface-water diversions and groundwater pumpage. Approximately one-sixth of the Nation's irrigated land is in the Central Valley, and about one-fifth of the Nation's groundwater demand is supplied from its aquifers.” Quoted from the USGS executive summary.
