Palo Verde Valley

The Palo Verde Valley is located in the Lower Colorado River Valley, next to the eastern border of Southern California with Arizona, United States. It is located on the Colorado Desert within the Sonoran Desert south of the Parker Valley. Most of the valley is in Riverside County, with the southern remainder in Imperial County. La Paz County borders to the east on the Colorado River.

The region is the ancestral home of several Native American tribes: the Quechan, the Chemehuevi and Matxalycadom or Halchidhoma, some who have Indian reservations in California and Arizona along the Colorado and Gila Rivers today.

The Palo Verde Valley is part of the Sonoran Desert's Colorado Desert. The Big Maria Mountains are north of the valley, and the Colorado River forms the valley's boundaries to the east and south. Other mountains nearby are the McCoy Mountains to the west (north in Interstate 10), the Chocolate Mountains to the south, the Little Maria Mountains to the northwest, and the Dome Rock Mountains to the east.

Agriculture is the valley's most important industry since indigenous farming. Crops include melons, alfalfa, cotton and vegetables. The Palo Verde Irrigation District (PVID), with its water sourced from the Palo Verde Diversion Dam, controls the canal system for these fields. Dating back to Thomas Blythe's filing on 1877, the PVID has the most senior Colorado River water rights of any California agency.
