Mexico poised to breach 75-year water treaty with US
Under the 1944 treaty, the US is committed to sending 1.5mn acre-feet of water from the Colorado River basin to Mexico in 12-month periods, which represents 10% of the river’s average flow, according to the US Congressional Research Service. Meanwhile, Mexico must send 1.75mn acre-feet in five-year cycles from the Rio Grande’s six major tributaries that cross its territory.
