FILE - In this March 5, 2008 file photo, water levels at the Colorado River's Horseshoe Bend begin to rise along the beaches just hours after the Glen Canyon Dam jet tubes began releasing water in Page, Ariz. Hispanic leaders in the West have formed a new group called Nuestro Rio to focus attention on the Colorado River, which has sustained generations of Latinos. The Colorado River system provides municipal water for more than 30 million people in Arizona, California, Colorado, Nevada, New Mexico, Utah, Wyoming and Mexico, but climate change, drought, population growth and wildlife needs have heightened competition for the system's limited water supplies.
