Official title: 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.
Introduced May 14, 2026 by John Cornyn · Last progress May 14, 2026
The bill strengthens enforceable minimum Rio Grande deliveries, reporting, and a compensation mechanism to protect U.S. farmers and border communities, but does so at the risk of diplomatic strain with Mexico, higher costs for consumers and taxpayers, potential trade retaliation, and reduced operational flexibility during droughts.
South Texas farmers, border communities, and local water managers gain more predictable, enforceable minimum annual Rio Grande deliveries (350,000 acre-feet), improving planning and agricultural stability.
Affected U.S. agricultural producers can receive direct, expedited financial compensation for verified economic losses tied to Mexico's shortfalls via a Trust Fund with automatic access, speeding relief.
The bill creates concrete enforcement tools (targeted duties on imports from areas tied to Rio Grande use) to pressure remedy of shortfalls, offering leverage to protect local water‑dependent economies.
U.S. enforcement measures and punitive duties could substantially strain diplomatic relations with Mexico, heighten bilateral tensions, and complicate broader cooperation on regional issues.
American consumers and taxpayers may bear higher costs: duties can raise prices (especially food imports) and the Treasury effectively funds compensation and administrative work, increasing public expenditure.
Targeted trade duties risk retaliatory measures or supply‑chain disruptions that could harm export‑dependent U.S. border businesses, jobs, and local economies.
Based on analysis of 8 sections of legislative text.
Imposes targeted U.S. import duties on Mexico when treaty water deliveries fall short and uses duties to fund compensation for South Texas farmers.
Creates a mechanism to enforce the 1944 water treaty requirement that Mexico deliver a minimum of 350,000 acre-feet of Rio Grande water annually by (1) triggering U.S. import duties on Mexican goods when Mexico is found to have a delivery shortfall and (2) using those collected duties to compensate South Texas agricultural producers who suffer economic losses from the shortfall. It assigns roles and deadlines to the Secretary of State, USTR, IBWC, and Secretary of Agriculture for making determinations, imposing duties, calculating losses, distributing compensation, and publicly reporting delivery and payment data.
