Rio Grande Valley farmers are reacting to a post on X by the state department.

Under the treaty, the U.S. delivers water to Mexico from the Colorado River and Mexico delivers water to the Rio Grande.

So far, Mexico has only delivered about a quarter of what it owes the U.S. over the last five years.
