The measures are supposed to buy the surrounding communities more time to plan for the very actual possibility the reservoir, the nation's second-largest, will soon run out of water and the power to provide hydropower amid the West's climate change-driven megadrought.

Step one is releasing more water from upstream on the Colorado River this year. The second is water can be held again in Lake Powell itself, as a substitute of being sent to downstream states.

The US Bureau of Reclamation expects the dual actions will boost Lake Powell by almost 1 million acre-feet of water. The reservoir contained about 5.8 million acre-feet of water as of Tuesday, according to the bureau, although its full capability is round 25 million acre-feet.

Without the emergency steps, the bureau estimated there was about a 25% probability the Glen Canyon Dam could have stopped producing hydropower by January. The dam generates energy for as many as 5.8 million houses and companies in seven states.

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

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

"We've never taken this step earlier than, but the potential threat on the horizon calls for immediate action," Assistant Secretary of Water and Science, Tanya Trujillo advised reporters. "We need to work together to stabilize the reservoir before we face a bigger disaster."

Lake Powell has dropped around 100 feet within the last three years as the West has been besieged by drought. As the water stage has fallen, Glen Canyon Dam has misplaced about 16% of its capability to generate energy.

Bryan Hill, normal manager of the public power utility in Web page, Arizona, likened the situation to judgment day.

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

The decisions made for Lake Powell additionally affect its downstream neighbor, Lake Mead, which is the biggest reservoir within the country.

Water cuts for those who depend on Lake Mead began in January, and Tuesday's choice might lead to further restrictions.

Lake Mead's water level is now low enough to show one of many reservoir's unique, 1971 water consumption valves for the first time. The valve can no longer draw water, in keeping with the Southern Nevada Water Authority, the agency chargeable for managing water sources for 2.2 million folks in southern Nevada, together with Las Vegas.

Officers over the weekend made another disturbing discovery brought on by Lake Mead's plummeting water degree: a physique in a barrel police say is a possible homicide victim from the Nineteen Eighties.

"The lake has drained dramatically over the last 15 years," stated Las Vegas Metropolitan Police Homicide Lieutenant Ray Spencer. "It is probably that we'll find extra bodies which were dumped in Lake Mead" as the water degree drops extra.
