Imperial County, California
Imperial County occupies California's southeast desert corner, where El Centro, Calexico and Brawley farm year-round on Colorado River water beside the Mexican border. Lithium extraction at the Salton Sea's geothermal field and renewable-energy buildout are the county's live development stories, set against Salton Sea contraction, irrigation-district water transfers, and the highest unemployment rate in the state.
