US denies Mexico extra Colorado River water, escalating drought tensions in South Texas.

The US has denied Mexico's request for additional Colorado River water for the first time since 1944, citing Mexico's failure to meet its obligations under a long-standing treaty. This decision may worsen tensions as South Texas farmers face severe drought and economic losses of nearly $1 billion in 2023. Mexico owes water deliveries under the treaty, and the issue is being addressed by the International Boundary and Water Commission.
