The United States has declined Mexico's request for a water delivery from the Colorado River to Tijuana, marking the first such refusal under a 1944 bilateral treaty. The agreement, which governs shared use of the Colorado and Rio Grande rivers, has historically prioritized collaborative water management despite occasional droughts.
This unprecedented decision comes amid growing strain on transboundary resources, with Tijuana's expanding population relying heavily on cross-border water agreements. Local authorities warn the denial could impact water security for residents of the border region, though U.S. officials emphasize existing treaty commitments remain intact.
Analysts suggest the move may reflect evolving priorities in water diplomacy, particularly as climate pressures intensify. Legal experts note the treaty allows for 'extraordinary circumstances' exemptions but provides no formal appeal mechanism for denied requests.
