HOLTVILLE, Calif. — Just north of the California-Mexico border, the All-American Canal cuts across 80 miles of barren, dune-swept desert. Up to 200 feet wide and 20 feet deep, the canal delivers the single largest share of Colorado River water to the fertile farmlands of the Imperial Valley.
It’s more water than what Los Angeles, Phoenix and Las Vegas get combined, and it’s used to grow lettuce, broccoli, carrots and spinach, as well as hay to supply beef and dairy operations, wheat, melons, lemons and other crops.
Since its founding in 1911, the Imperial Irrigation District has held some of the most senior water rights on the river, and it is among the last in line to take cuts. Its water rights, which date to 1901, support the local farm economy and sustain a substantial portion of the nation’s food supply.
