The U.S. is denying Mexico’s request for Colorado River water for the first time since the two countries signed a water-sharing treaty in 1944.
The Trump administration said it will deny a special request to deliver Colorado River water to Tijuana.
The water treaty Mexico and the U.S. signed in 1944 compels the U.S. to share Colorado River water with Mexico, and Mexico to share water from the Rio Grande with the U.S.
But Mexico has recently fallen behind on water deliveries to the U.S. Climate change and drought have meant less water to go around in dry northern Mexico.
In a social media post, the U.S. State Department’s Bureau of Western Hemisphere Affairs said Mexico’s failure to deliver water has been “decimating American agriculture.”
