U.S. officials announced plans Tuesday that they characterized as extraordinary to keep hundreds of billions of gallons of water stored in a reservoir on the Utah-Arizona line to prevent it from shrinking more amid prolonged drought and climate change.
The U.S. Bureau of Reclamation plans to hold back about 480,000 acre-feet of water in Lake Powell to maintain Glen Canyon Dam's ability to produce hydropower for millions of homes and businesses in the region. That's roughly enough water to serve 1 million to 1.5 million average households annually.
