The Colorado River is the source of the irrigation water that brings life to this desert region. The 80-mile long All-American Canal delivers water to the southeast corner of the Imperial Valley. Roughly 2.8-3.0 million acre-feet of water are used per year to grow the crops and livestock to help feed the nation. Irrigation water is delivered via 16,000 miles of canals managed by the local water company, the Imperial Irrigation District (IID). Most of the water is delivered by gravity as the valley is tilted slightly to the north. Current water price is $20.00 per acre-foot (326,000 gallons) delivered to the farmer's headgate.
