The measures are intended to buy the surrounding communities extra time to plan for the very real chance the reservoir, the nation's second-largest, will quickly run out of water and the flexibility to provide hydropower amid the West's climate change-driven megadrought.

The first step is releasing more water from upstream on the Colorado River this yr. The second is water will be held again in Lake Powell itself, instead of being sent to downstream states.

The US Bureau of Reclamation expects the twin actions will increase Lake Powell by almost 1 million acre-feet of water. The reservoir contained about 5.8 million acre-feet of water as of Tuesday, based on 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 might have stopped producing hydropower by January. The dam generates energy for as many as 5.8 million properties and businesses in seven states.

The company mentioned in a press release Tuesday's choice was intended to guard "hydropower technology, the power's key infrastructure, and the water supply for town of Page, Arizona, and the LeChee Chapter of the Navajo Nation."

The emergency actions will buy the federal authorities 12 months as it considers longer-term measures.

"We have never taken this step before, however the potential risk on the horizon calls for immediate action," Assistant Secretary of Water and Science, Tanya Trujillo told reporters. "We have to work collectively to stabilize the reservoir before we face a larger crisis."

Lake Powell has dropped round 100 ft 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, normal manager of the general public energy utility in Web page, Arizona, likened the situation to judgment day.

"We're knocking on the door of judgment day," Hill beforehand told CNN. "Judgment day being when we have no water to provide anyone."

The selections made for Lake Powell also have an effect on its downstream neighbor, Lake Mead, which is the biggest reservoir in the nation.

Water cuts for many who depend on Lake Mead began in January, and Tuesday's decision might result in further restrictions.

Lake Mead's water stage is now low enough to reveal one of the reservoir's unique, 1971 water intake valves for the first time. The valve can now not draw water, in keeping with the Southern Nevada Water Authority, the company accountable for managing water sources for two.2 million individuals in southern Nevada, together with Las Vegas.

Officers 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 likely homicide victim from the Eighties.

"The lake has drained dramatically over the past 15 years," stated Las Vegas Metropolitan Police Murder Lieutenant Ray Spencer. "It is likely that we'll discover further our bodies which were dumped in Lake Mead" as the water degree drops more.
