 II  119th CONGRESS  2d Session  S. 4549  IN THE SENATE OF THE UNITED STATES   May 14, 2026   Mr. Cornyn  introduced the following bill; which was read twice and referred to the  Committee on Foreign Relations    A BILL
To ensure the reliable delivery of water to the United States under the 1944 Water Treaty, to provide a mechanism to compensate United States agricultural producers for economic losses resulting from delivery shortfalls, and for other purposes.
1.
Short title
This Act may be cited as the   Water Assurance and Treaty Enforcement for Rio Grande Farmers Act   or the   WATER for Farmers Act  .
2.
Findings
Congress makes the following findings:
(1)
The Treaty relating to the Utilization of Waters of the Colorado and Tijuana Rivers and of the Rio Grande, signed at Washington February 3, 1944 (9 Bevans 1166), between the United States and Mexico (in this Act referred to as the  1944 Water Treaty  or the  Treaty ), intends for Mexico to deliver annually to the United States a minimum of 350,000 acre-feet of water from the Rio Grande basin, measured in cycles of 5 consecutive years.
(2)
The practice of relying on storm events to comply with the terms of the Treaty, unpredictable yearly deliveries, and accumulating large deficits, create profound uncertainty and have inflicted severe economic harm on United States agricultural producers and communities in South Texas who rely on regular delivery of water under the Treaty.
(3)
Those annual economic harms have a direct impact on interstate and international commerce, distort agricultural markets, and create unfair competitive conditions for United States agricultural producers.
(4)
Recent diplomatic agreements between the United States and Mexico, including Minutes 325 and 331 of the International Boundary and Water Commission, do not contain sufficient enforcement mechanisms to guarantee the reliable delivery of water necessary for agricultural planning and production.
(5)
New enforcement mechanisms are necessary to ensure the benefits of the 1944 Water Treaty are fully realized by the United States.
3.
Determination of water delivery shortfalls

In general
Not later than 30 days after the end of each year of a five-year water delivery cycle under the 1944 Water Treaty, the Secretary of State, in consultation with the United States Commissioner of the International Boundary and Water Commission and the Secretary of Agriculture, shall determine whether Mexico has delivered the quantity of water for that year required under subsection (b). If it is determined that Mexico has not delivered that quantity of water for that year, Mexico shall be considered in a water delivery shortfall for that year.
(b)
Annual delivery requirement
(1)
In general
The minimum quantity of water required to be delivered by Mexico by the end of each year of a cycle of 5 consecutive years under the 1944 Water Treaty shall be 350,000 acre-feet.
(2)
Actions by Secretary of State
The Secretary of State shall take such actions as are necessary to formalize the requirement described in paragraph (1).

(1)
increasing the rates of duty applicable to such goods; or
(2)
expanding the categories of goods to which such duties apply.

(a)
In general
Not later than 90 days after a determination is made under section 3(a) that Mexico is in a water delivery shortfall for a year, the Secretary of Agriculture, in consultation with the Secretary of State and the United States Commissioner of the International Boundary and Water Commission, shall calculate the direct economic losses incurred by United States agricultural producers in the Rio Grande Valley as a result of the shortfall.

(3)
Shortfall volume in acre-feet
The term  shortfall volume in acre-feet  means the difference between Mexico's required water delivery under section 3(b) for a year and the actual volume of water delivered to the United States in acre-feet during that year.
7.
