South Texas Needs Water NOW!

Texas’ last sugar mill, Rio Grande Valley Sugar Growers Association in Santa Rosa, was forced to close after more than 50 years in business, cutting $100 million out of the economy and about 500 jobs. Made up of more than 100 farmers, the cooperative’s shutdown marks the loss of one of the region’s biggest farming operations and is a direct result of an ongoing water crisis.

Much of the regional water crisis is due to Mexico’s failure to comply with the 1944 Water Treaty requiring it share reservoir supplies with the United States. The closure of the sugar mill has set off alarm bells with both state and federal government officials bringing much needed attention to South Texans’ 30-year battle with Mexico for water.

Background of the 1944 Water Treaty

The 1944 Water Treaty, officially known as the Treaty Relating to the Utilization of Waters of the Colorado and Tijuana Rivers and of the Rio Grande, was signed between the United States and Mexico on February 3, 1944. The treaty was designed to allocate the waters of these rivers between the two nations, ensuring that both countries had reliable access to water resources vital for agriculture, industry, and urban development.

Under the terms of the treaty, the United States is obligated to deliver to Mexico 1.5 million acre-feet of water annually from the Colorado River. In return, Mexico is obligated to deliver to the United States not less than 350,000 acre-feet as an average amount annually over cycles of five consecutive years, for a total delivery of 1,750,000 AF in a cycle. The 1944 Treaty provides that “ [i]n the event of extraordinary drought... any deficiencies existing at the end of the aforesaid five-year cycle shall be made up in the following five-year cycle.” This agreement is overseen by the International Boundary and Water Commission (IBWC), a binational body established to manage and enforce the terms of the treaty and address any disputes that arise.

Key Considerations:

  • Mexico has struggled to meet its water delivery obligations consistently since 1992. Mexico has not met its Rio Grande delivery obligations three times within a five-year cycle, ending the cycles of 1992-1997, 1997-2002, and 2010-2015 in deficits. Each of those debts was carried over to the following consecutive cycle. Each debt was eventually paid but South Texans have suffered the impact of unpredictable water deliveries for over 30 years.

  • The last five-year cycle ended in conflict in 2020, with farmers in Chihuahua protesting water deliveries to the U.S. In a last-minute deal, Mexico agreed to transfer water stored at the international reservoirs to the U.S. to end the cycle without a deficit to avoid retaliation from the Trump Administration.

  • We are now well into the fourth year of the current 5-year cycle and Mexico has “delivered” only 400,000 acre-feet to the U.S due to spillover from the Luis L. Leon dam, which is not a delivery from a reservoir.  It is unlikely that Mexico will end the current 5-year cycle in compliance and will ask for an extension claiming “extraordinary drought.” However, During the current five-year cycle, Mexico gained 600,338 acre-feet in June of 2021 and 2,238,653 acre-feet in August of 2022, in the six Treaty tributaries that the U.S. is entitled to receive 1/3 flows from. At one time, Mexico had 2,966,676 acre-feet accumulated, yet none of that water was released to the Rio Grande to comply with Treaty requirements.

  • Since 2002, Chihuahua has nearly doubled its acres in specialty crop production.  For example, it is now the number one producer of pecans in North America, surpassing New Mexico.  While the agricultural economy suffers in South Texas, Chihuahua’s agricultural economy flourishes using the water that should be delivered to the U.S. under the treaty.

  • A study, Estimated Economic Impacts of Irrigation Water Shortages on Lower Rio Grande Valley Agriculture by Texas A&M AgriLife, estimates a potential 2024 total loss in economic output of over $993.2 million due to the absence of irrigation water for crop production in the region. The report also expects a loss of over 8,000 jobs in the region. According to the report, the loss of irrigation water is largely due to Mexico’s failure to fulfill its water deliveries on annual basis to the U.S. under the treaty. Read full report here:

Key Texas State Government Contacts

While action is required from Congress and ultimately the U.S. State Department to enforce the 1944 Water Treaty, listed below are a few key state government contacts that could help to put pressure on them.

TACC will continue to support the efforts of many other associations such as the Texas Farm Bureau, Texas Citrus Mutual, and Texas International Produce Association to bring awareness and a resolution to this ongoing issue.
