A bill to ensure that United States diplomats and officials of the U.S. Section of the International Boundary and Water Commission are able to advance efforts seeking compliance by the United Mexican States with the 1944 Treaty on Utilization of Waters of the Colorado and Tijuana Rivers and of the Rio Grande.

This bill directs the U.S. Secretary of State to use diplomatic resources to advance efforts ensuring Mexico complies with the 1944 water treaty, which requires Mexico to deliver 350,000 acre-feet of water annually to the U.S. (averaged over five years). It addresses Mexico’s failure to meet obligations - delivering under 400,000 acre-feet by March 2024 toward a 1.75 million acre-foot requirement by 2025 - impacting Texas farmers and causing economic losses like the closure of a sugar mill. The key mechanism is requiring U.S. diplomats and officials to actively negotiate compliance and establish reliable water delivery terms. The bill directly affects U.S. water users in the Lower Rio Grande Valley, who face shortages due to Mexico’s non-compliance.
