Key Points
1. Mexico will start Rio Grande (Río Bravo) deliveries on Monday and ship 249.163 million cubic meters by January 31, 2026 after a tariff risk from President Donald Trump.
2. The launch is a partial repair: U.S. and Texas officers say Mexico stays about 986 million cubic meters behind within the present cycle, with farmers on each side blaming drought.
3. A 1944 treaty as soon as dealt with quietly by engineers is now a political headline, entangled with Mexico’s water legislation and rural protests.
Mexico and the United States introduced Friday a stopgap deal to chill a border dispute: Mexico will begin delivering water “step by step” on Monday, aiming to switch 249.163 million cubic meters—202,000 acre-feet—by the tip of January.
The settlement follows days of public strain. Trump warned he would impose a 5% tariff if Mexico didn’t ship what he stated was owed “earlier than the tip of the 12 months,” and he framed the dispute on-line as Mexico “stealing” water from Texas farmers.
Texas agriculture teams and state leaders echoed that message, arguing the shortfall is much bigger than the brand new launch.
Behind the numbers sits an previous discount below new stress. The 1944 treaty requires Mexico to supply 2.185 billion cubic meters from Mexican tributaries of the Rio Grande over rolling five-year cycles.
Deliveries are tracked by the binational fee often known as CILA in Mexico and the IBWC within the United States.


Mexico Turns On Rio Grande Water Deliveries After U.S. Tariff Threat
Mexico’s case is bodily: northern states comparable to Chihuahua, Coahuila, Nuevo León, and Tamaulipas have confronted extended drought, leaving rivers and reservoirs too low for fast catch-up releases with out squeezing native ingesting water and irrigation.
The U.S. case is financial: Texas growers say shortages are already reshaping planting choices and revenues.
The story behind the story is that water is not a quiet technical file. It is changing into leverage in commerce politics and a take a look at of home governance.
In Mexico, the battle is sharpened by a nationwide water legislation accredited on December 4 and by farmer protests in opposition to tighter guidelines and larger federal management.
For expats and buyers, the lesson is blunt: local weather threat is now coverage threat, and coverage threat can turn out to be tariff threat.
