A fter one of the Colorado River’s driest years in decades, Lake Mead and Lake Powell — the largest reservoirs in the country — could see alarming declines in the coming years, the U.S. Bureau of Reclamation announced today.

Federal officials announced Friday they would continue water allocation cuts on the Colorado River for the fifth consecutive year following a persistent drought that’s shrunken the river’s largest reservoir.

Nevada faces a third year of Colorado River water cuts, while Las Vegas avoids new restrictions due to past conservation efforts.
