Imperial Irrigation District
From Wikipedia, the free encyclopedia
Formed in 1911, the Imperial Irrigation District (IID) was made 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.
Since 1942, water has been diverted at Imperial Dam on the Colorado River through the All-American Canal, all of which the IID operates and maintains.
