Summary

What This Bill Does

This bill creates a system to pressure Mexico into delivering water owed to the United States under a 1944 treaty governing the Colorado, Tijuana, and Rio Grande rivers. It requires the Secretary of State to report annually on whether Mexico is meeting its water delivery obligations, and gives the President authority to deny Mexico's requests for emergency water deliveries and limit diplomatic engagement with Mexican economic sectors if Mexico falls short.

Who Benefits and How

US farmers and irrigators in the Lower Rio Grande Valley and Texas border regions would benefit from increased water deliveries if Mexico complies with treaty obligations. US municipal water systems in border communities would gain more reliable water supplies. US agricultural interests gain leverage to pressure Mexico into water treaty compliance.

Who Bears the Burden and How

Mexican agricultural irrigation districts face the risk of losing access to emergency US water deliveries. Mexican municipal water systems (especially Tijuana) could be denied emergency Colorado River water during shortfalls. The US State Department must produce detailed annual reports and certifications. US-Mexico diplomatic relations and cross-border trade could be strained.

Key Provisions

  • Requires annual State Department reports on Mexico's water deliveries (minimum 350,000 acre-feet per year threshold)
  • Mandates denial of Mexico's "non-Treaty" emergency water requests if Mexico fails to meet delivery obligations
  • Authorizes the President to limit diplomatic engagement with Mexican economic sectors dependent on US water
  • Provides exception for true ecological, environmental, or humanitarian emergencies vital to US interests
  • Preserves engagement related to fentanyl and synthetic drug interdiction
