MEXICO CITY — Mexico and the United States said Monday they had reached an agreement that involves Mexico immediately sending more water from their shared Rio Grande basin to Texas farmers after U.S. President Donald Trump threatened tariffs and sanctions earlier this month.

The countries’ joint statement Monday, while lacking specific details of the agreement, said both countries had agreed that the 1944 treaty regulating how the water is shared was still beneficial for both countries and not in need of renegotiation.

Under the treaty, Mexico must deliver 1,750,000 acre-feet of water to the U.S. from six tributaries every five years, or an average of 350,000 every year.

An acre-foot is the amount of water needed to cover 1 acre of land to a depth of 1 foot.

But Mexico is at a high risk of not meeting that deadline as the end of the current cycle approaches in October.

The treaty allows Mexico to run a water debt in the first four years of each cycle, if it can make it up in the fifth.
