CIRS Blog about Rural California
California is experiencing a long term drought. As a result, CIRS is examining various aspects of the California water system. This week, we are looking at a desert region where per capita water use is the highest in the state for a non-industrial area at 736 gallons per person per day.

The Coachella Valley is located in eastern Riverside County, California. The entire valley sits in the basin north of the Salton Sea bounded by various strands of the very active San Andreas Fault System. The San Andreas Fault traverses the Valley's east side. The Santa Rosa Mountains to the West are part of the Elsinore Fault Zone.The Inland Empire-Salton Trough region is geologically and seismologically the most complex part of the San Andreas Fault system in southern California. Over the past 15 million years, several strands of the main San Andreas Fault have moved coastal California northwestward in relation to the desert interior. The trough of the Coachella Valley is surrounded by mountain ranges rising up to 11,000 feet in elevation while the valley floor drops to 250 feet below sea level at its lowest around the town of Mecca. In the summer, daytime temperatures range from 104 ° F to 112 ° F and winter temperatures range from 68 F to 88 F making the Coachella Valley a very popular winter resort. The Valley is the northwestern extension of the Sonoran Desert to the southeast and is extremely arid. The majority of rainfall occurs during the winter months. Rain may sometimes fall during the summer months as a result of the desert monsoon.
