U.S. , Mexico Sign Water Sharing Pact

After five years of effort, the United States and Mexico signed an agreement for new rules on sharing water from the Colorado River in November. The pact gives Mexico water storage capacity in Lake Mead. Mexico will forfeit some of its share of the river during shortages, bringing itself in line with western U.S. states that already have agreed how much they will surrender when waters recede. Mexico also will capture some surpluses when waters rise. Also under the plan, water agencies in Arizona, California, and Nevada will buy water from Mexico, which will use some of the money to upgrade its canals and other infrastructure. The agreement is a major amendment to a 1944 treaty considered sacred by many south of the border. The treaty grants Mexico 1.5 million acre-feet of river water each year.
