An agreement amending the longstanding treaty between the U.S. and Mexico on management of the Colorado River will continue the practice of water shortage sharing, but also fund new conservation and environmental programs, and aim to reduce the risk of ruinous drought. The two nations are tentatively scheduled to execute the agreement—Minute 323, an amendment to a 1944 water treaty—on Sept. 26 in Mexico’s Ciudad Juarez. Minute 323 will govern water flows in the Colorado River and other water management issues by extending an existing binational agreement, Minute 319, which was set to expire at the end of 2017.
