ALL AMERICAN CANAL

This is a photo taken on a cool fall morning in Imperial Valley, California, at the place where the main canal that supplies water to this desert valley terminates. Lateral canals branch out from here, to distribute water to all towns and farms in the valley. The mountain in the background is MT. Signal, a local landmark.The mountain is located in Mexico. MT.Signal served as a guide to early settlers and travelers in this area. The canal parallels the Mexican border by about 300 yards at this point.

Water for irrigation is diverted at Imperial Dam into the All American Canal. The canal and its main branch, the Coachella Canal, carry water to the project areas where it is delivered to land through distribution systems.

Colorado River water is discharged through the Imperial Dam headworks into a concrete-lined channel approximately 360 feet wide which is divided into four channels directing the water into desilting basins. The initial capacity of the canal is 15,155 cubic feet per second (approximately 30,060 acre-feet per day). It has a width of 232 feet and depth of 21 feet at normal water surface, with a bottom width of 160 feet.
