California Water Library
The 11,000 square-mile South Coast region is the most urbanized and populous region in the state, home to more than half the state’s population residing in just 7% of the state’s total land area. The region receives imported water supplies from the State Water Project, the Los Angeles Aqueduct, and the Colorado River Aqueduct which account for about half the region’s water demands; the remaining demands are met through groundwater, recycled water, and some desalinated water.
