Visitors view the dramatic bend in the Colorado River at the popular Horseshoe Bend in Glen Canyon National Recreation Area, in Page, Ariz., on Sept. 9, 2011. Some 40 million people in Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming draw from the Colorado River and its tributaries. This week, although after presstime, the U.S. Bureau of Reclamation is expected to publish hydrology projections that would trigger agreed-upon cuts to states that rely on the river.
