Imperial County - Imperial Valley

Imperial County is located in the southwest corner of California immediately east of San Diego County in the Imperial Valley and is the least populated county in the state. The county seat is El Centro. Although the region is a desert, the economy is based primarily on agriculture which is supported by irrigation, with water being supplied by the Colorado River via the All-American Canal. The Salton Sea is located in both Imperial County and Riverside County.

The All-American Canal is an 82-mile canal/aqueduct that transfers water from the Colorado River to the agricultural areas of the Imperial Valley and nine cities. Agricultural runoff in the Imperial Valley drains into the Alamo River and New River which drain into the Salton Sea.

Completed in 1949, the Coachella Canal is a 122-mile canal or aqueduct that carries Colorado River water for irrigation northwest from the All American canal to the Coachella Valley north of the Salton Sea in Riverside County. The canal is vital to the numerous agricultural businesses operating in the region.

Cities in Imperial County include EI Centro, Calexico, Brawley, and Imperial. Unincorporated communities in Imperial County include Salton City, Desert Shores, Salton Sea Beach, Winter Haven, and Bombay Beach.

The Salton Sea is a large, shallow, saline lake located southeast of the Coachella Valley, in Southern California within Riverside County and Imperial County. While the dimensions vary depending upon rain and agricultural runoff, it averages 35 miles by 15 miles with a maximum depth of 44 feet. It is the largest lake in California. The lake's salinity is greater than the Pacific Ocean, but less than that of the Great Salt Lake in Utah. The level of salt has been increasing over the years limiting the types of fish that can survive. The primary inflows are the Alamo River, the New River, and the Whitewater River. There are no major outflows. There are a number of groups, including the Salton Sea Authority and the Sonny Bono Salton Sea National Wildlife Refuge organization, working on strategies to save the Salton Sea. Towns along the Salton Sea include: Bombay Beach, Desert Beach, Desert Shores, Salton City, Salton Sea Beach, and North Shore.

Lithium Valley

Lithium is a vital mineral in the rechargeable batteries used by consumers in portable computing devices, electric vehicles and battery storage. Today, the United States has only 1 % of global lithium being mined and processed, according to the U.S. Geological Survey.

The earth deep below the southern portion of the Salton Sea, which is located in Imperial County, is rich in hot, mineral-abundant geothermal brine that contains some of the world's largest deposits of lithium. It is estimated that Imperial County may hold as much as fifteen million metric tons of lithium, in addition to other rare minerals.

Imperial County officials and industry professionals envision a "Lithium Valley" in Imperial County that would establish California as a global production hub that could employ thousands of workers and propel the economic future of Imperial County residents for generations to come.
