All-American Canal
All-American Canal, irrigation canal, south-eastern California, near the Mexican border. It stretches from the Colorado River near Yuma, Arizona, where it is fed by reservoirs formed by the Laguna and Imperial dams, west across the Colorado Desert to Calexico, California. Built between 1934 and 1940 as a public-works project during the Depression, it is 129 km (80 mi) long and about 61 m (200 ft) wide. Its water is used to irrigate the fertile but arid Imperial Valley. The Coachella Canal (completed 1948) branches from the All-American Canal, extending 198 km (123 mi) north-west to irrigate the Coachella Valley.
