Imperial Irrigation District

The Imperial Irrigation District (IID) was formed in 1911 under the California Irrigation District Act to acquire the properties of the bankrupt California Development Company and its Mexican subsidiary. The IID had acquired 13 mutual water companies, which had developed and operated distribution canals in the Imperial Valley, by 1922. It is currently based in Imperial, California.

Prior to 1942, irrigation water for the Imperial Valley was diverted from the Colorado River near Pilot Knob into the IID-operated Alamo Canal (also known as the Imperial Canal). Since 1942, water has been diverted at the Imperial Dam on the Colorado River through the All-American Canal, all of which the IID operates and maintains.

The IID also remotely operates the Brock Reservoir by opening and closing the inlet and outlet gates and regulating the amount of water diverted into the reservoir and returned to the main system.

The district also supplies electricity to residents of the Imperial Valley including the cities of El Centro, Calexico, Holtville, Brawley and other small towns in the area.

Imperial Irrigation District Electricity provides electric power to more than 145,000 customers in the Imperial Valley and parts of Riverside and San Diego counties. As the sixth largest utility in California, IID Energy controls more than 1,100 megawatts of energy derived from a diverse resource portfolio that includes its own generation, and long- and short-term power purchases.
