The measures are supposed to purchase the surrounding communities extra time to plan for the very real possibility the reservoir, the country's second-largest, will quickly run out of water and the power to provide hydropower amid the West's local weather change-driven megadrought.
Step one is releasing extra water from upstream on the Colorado River this 12 months. The second is water will probably be held back in Lake Powell itself, as an alternative of being despatched to downstream states.
The US Bureau of Reclamation expects the twin actions will boost Lake Powell by nearly 1 million acre-feet of water. The reservoir contained about 5.8 million acre-feet of water as of Tuesday, in accordance with the bureau, although its full capacity is around 25 million acre-feet.
With out the emergency steps, the bureau estimated there was a couple of 25% probability the Glen Canyon Dam may have stopped producing hydropower by January. The dam generates energy for as many as 5.8 million houses and businesses in seven states.
The company mentioned in a statement Tuesday's choice was supposed to guard "hydropower generation, the facility's key infrastructure, and the water provide for the town of Web page, Arizona, and the LeChee Chapter of the Navajo Nation."
The emergency actions will purchase the federal government 12 months because it considers longer-term measures.
"Now we have never taken this step before, however the potential danger on the horizon calls for immediate action," Assistant Secretary of Water and Science, Tanya Trujillo advised reporters. "We need to work collectively to stabilize the reservoir before we face a larger disaster."
Lake Powell has dropped around 100 feet in the final three years as the West has been besieged by drought. As the water level has fallen, Glen Canyon Dam has misplaced about 16% of its capability to generate power.
Bryan Hill, common supervisor of the general public power utility in Web page, Arizona, likened the situation to judgment day.
"We're knocking on the door of judgment day," Hill previously advised CNN. "Judgment day being when we have no water to offer anyone."
The choices made for Lake Powell also affect its downstream neighbor, Lake Mead, which is the largest reservoir in the nation.
Water cuts for many who rely on Lake Mead began in January, and Tuesday's resolution might lead to additional restrictions.
Lake Mead's water level is now low sufficient to reveal one of the reservoir's authentic, 1971 water consumption valves for the first time. The valve can now not draw water, based on the Southern Nevada Water Authority, the company responsible for managing water resources for 2.2 million folks in southern Nevada, together with Las Vegas.
Officials over the weekend made one other disturbing discovery brought on by Lake Mead's plummeting water stage: a body in a barrel police say is a probable homicide victim from the 1980s.
"The lake has drained dramatically during the last 15 years," said Las Vegas Metropolitan Police Homicide Lieutenant Ray Spencer. "It's possible that we will discover extra our bodies which were dumped in Lake Mead" as the water level drops more.
