All-American Canal (IID)

All-American Canal (82 miles; concrete-lined; completed 1942; operated by Imperial Irrigation District) diverts Colorado River water from Imperial Dam (Yuma AZ) entirely on US territory (replacing the older Alamo Canal that crossed into Mexico) to the Imperial Valley in California. At full diversion, the All-American Canal delivers up to 5.36 million AF/yr — the largest single point of diversion on the entire Colorado River. The Canal is divided at Siphon Drop Powerplant into the All-American Canal main channel to the Imperial Valley and the Coachella Canal (123 miles) to the Coachella Valley. The lining of the All-American Canal (2007-2009) — a controversial $240M project — reduced seepage losses by approximately 67,700 AF/yr but eliminated groundwater recharge on the US-Mexico border that had supported Mexican farming communities and wetlands on the Mexican side.
