Significance: The Colorado River Aqueduct pumps water from the Colorado River through, over, and across mountains and desert in a 242-mile-long march to the coastal plain of Southern California. When completed, it was one of the longest water-conveyance facilities in the world. The aqueduct includes power lines, tunnels, siphons, covered conduits, open canals, dams, reservoirs, and five pumping plants, involving ingenious engineering solutions and newly-introduced construction equipment. The project also employed over 35,000 people during its eight-year span and as many as 10,000 at one time, making it southern California's single-largest work opportunity during the Great Depression. In 1995, the Colorado River Aqueduct was named a National Historic Civil Engineering Landmark by the American Society of Civil Engineers. Today, it is the major water supply for urban and suburban southern California.
