Federal water managers say the level of Lake Powell could fall to historic lows by the end of the year amid worsening drought conditions across the Colorado River Basin. The U.S. Bureau of Reclamation’s newest 24-month study predicts that by December the lake could, for the first time, fall to 3,490 feet, or “minimum power pool,” the lowest level at which Glen Canyon Dam can produce electricity. In addition, if dry conditions persist officials say by March 2027, Powell could drop to 3,476 feet—the lowest level on record since the lake was filled decades ago, possibly limiting the dam’s ability to release water.
