How to Make California’s Southland Water Independent for $30 Billion

The megapolis on California’s southern coast stretches from Ventura County on the northern end, through Los Angeles County, Orange County, down to San Diego County on the border with Mexico. It also includes the western portions of Riverside and San Bernardino counties. Altogether these six counties have a population of 20.5 million residents. According to the California Department of Water Resources, urban users consume 3.7 million acre feet of water per year, and the remaining agricultural users in this region consume an additional 700,000 acre feet.

Much of this water is imported. In an average year, 2.6 million acre feet of water is imported by the water districts serving the residents and businesses in these Southland counties. The 701 mile long California Aqueduct, mainly conveying water from the Sacramento River, contributes 1.4 million acre feet. The 242 mile long Colorado River Aqueduct adds another 1.0 million acre feet. Finally, the Owens River on the east side of the Sierras contributes 250,000 acre feet via the 419 mile long Los Angeles Aqueduct.
