Salazar, Elvira Announce Water Agreement to Support Response to Mexicali Valley Earthquake

Leaders Lay Groundwork for Comprehensive U.S.-Mexico Water Agreement on Colorado River

Last edited 09/29/2021

MEXICO CITY – U.S. Interior Secretary Ken Salazar and Mexican Environment and Natural Resources Secretary Juan Rafael Elvira Quesada today announced the successful completion of an agreement, known as ‘Minute 318,' to adjust water deliveries on the Colorado River to areas damaged by a devastating earthquake on April 4, 2010.

Following their meeting in Mexico City, the Secretaries also announced a commitment by the two governments to initiate, in January 2011, high-priority discussions on a comprehensive long-term agreement between the U.S. and Mexico on the management of the Colorado River.

“Through this water agreement, the U.S., Mexico, and the seven Colorado River Basin states are bringing resources together for our mutual benefit and for the benefit of our neighbors whose irrigation systems and livelihoods have been damaged by the Easter Sunday earthquake,” said Salazar, who is in Mexico City to discuss water, conservation, and natural resource issues with President Calderon and Mexican government officials. “Minute 318 is a remarkable achievement from a humanitarian perspective, but it also lays important groundwork for a much-needed comprehensive water agreement with Mexico on how we manage the Colorado River.”

“Water users and stakeholders up and down the Colorado River have a strong interest in a comprehensive water agreement that would enhance reliability, certainty, and efficiency of water deliveries,” said Bureau of Reclamation Commissioner Michael Connor, who coordinated with the seven Colorado River Basin States and the International Boundary and Water Commission to reach the Minute 318 agreement. “The good faith negotiations that resulted in Minute 318 will help pave the way toward the comprehensive agreement for Colorado River management that is so needed on both sides of the border.”

Secretary Salazar and Secretary Elvira commended the work by the U.S. and Mexican Commissioners of the International Boundary and Water Commission (IBWC), Edward Drusina and Roberto Salmon, who led their respective nation's negotiation teams for Minute 318.

Under Minute 318, Mexico will be able to temporarily defer delivery of a portion of its annual Colorado River water allotment while repairs are made to the irrigation system in the Mexicali Valley of Baja California as a result of an April 4, 2010 earthquake. This agreement is founded on the 1944 Water Treaty between the U.S. and Mexico.

Under the 1944 Water Treaty between the United States and Mexico, Mexico is allotted a guaranteed quantity of Colorado River Water each year. Absent surplus or extraordinary drought conditions, Mexico's annual allotment is 1.5 million acre-feet (maf).

Minute 318 allows Mexico to defer delivery of up to 260,000 acre-feet of its annual allotment through December 31, 2013. Beginning in 2014, Mexico could begin recovery of the amounts of Colorado River water deferred during the three-year period, subject to the progress of reconstruction of the Mexican irrigation system and the status of Colorado River reservoirs.

In their meeting today, Secretaries Salazar and Elvira, Commissioner of Reclamation Connor, Director General of the Mexican National Water Commission Jose Luis Luege Tamargo, and IBWC Commissioners Drusina and Salmon discussed the need for a comprehensive agreement on Colorado River water management issues, particularly in light of ongoing drought conditions and the prospect of continuing declines in reservoir levels.

Secretaries Salazar and Elvira identified the negotiations on a comprehensive agreement as a top priority for 2011. The leaders said they would direct their representatives to begin negotiations of the comprehensive water agreement in January, 2011.

Commissioner Connor noted that a comprehensive agreement is of particular importance in light of ongoing, historic drought in the Colorado River Basin:

  • Since 2000, Colorado River basin reservoirs have dropped from nearly full to approximately 55% of total storage.
  • Lake Mead currently stands at 39% of capacity, lower than it has been since it was filling in the 1930s.
  • The last 11 years have been the driest in a century of recorded history, and among the driest 1% of periods in over 1,000 years.
  • Current projections show that if current drought conditions persist, the Lower Basin (Arizona, California and Nevada) may be subject to the first-ever domestic shortage declaration on the Colorado River as early as 2012; the likelihood of shortage conditions by 2014 is approximately 35%.
