Some 40 million people in Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming draw from the Colorado River and its tributaries. The U.S. Bureau of Reclamation is expected to publish hydrology projections on Tuesday, Aug. 16, 2022, that will trigger agreed-upon cuts to states that rely on the river. (AP Photo/Ross D.
