The reduction of releases from Lake Powell from 7.48 maf to 7.00 maf in WY 2022 resulted in a reduced release volume of 0.480 maf that normally would have been released from Glen Canyon Dam to Lake Mead as part of the 7.48 maf annual release volume, consistent with routine operations under the 2007 Interim Guidelines. The reservoir is also formed by the Hoover Dam, which produces about 4 billion kilowatt-hours of hydroelectric power every year. Drought conditions in the Southwest worsened significantly over the past week, the US Drought Monitor reported Thursday. They are typically updated every January, April, and August, while probabilistic results for the 2-year period are updated every month. The combination of dry soils, a third La Nina and critically low reservoirs levels is a major concern.. This is due to recent heavy rainfall and winter storms that swept across Nevada and the neighboring states. The reservoir relies on rainfall and winter snowpack to replenish its water levels.

There is some opportunity for the Colorado River to pick up more inflow between Lake Powell and Lake Mead, from springs and small creeks in the Grand Canyon but drought and climate change have been reducing these flows, as well. Lake Mead's water levels . Lake Powell and Lake Mead operations are modeled as if the 0.480 maf had been delivered to Lake Mead for Lake Powell operating tier and condition determination purposes for the U.S. Lower Basin and for Mexico. Importantly, the Bureau of Reclamations studies are based on historical data from the 1990s a much wetter period in the West, said Eric Kuhn, a retired former manager of the Colorado River Water Conservation District.
