Mexico is at risk of breaching a 75-year old water treaty with the US if it does not come up with a new strategy to deliver 457,800 acre-feet (565 million cubic meters – Mm3) of water to its northern neighbor by October 24.

That amount represents 350,000 acre-feet of water that the Latin American country is expected to deliver annually under the US-Mexico water treaty of 1944, in addition to making up for the delayed delivery of around 108,000 acre-feet that it has postponed during the 2015-20 cycle.
