The federal government said Monday it plans to release an above-average amount of water from a major reservoir in the Southwestern U.S. this year, but it’s less than many hoped after a healthy snow season across much of the West. The Bureau of Reclamation, which manages dams and reservoirs on the Colorado River, said it will release 9 million acre-feet from Lake Powell, sending it down the Colorado into Lake Mead, where it will be tapped by Arizona, California and Nevada. An acre-foot can supply two typical homes for a year.
