The measures are meant to purchase the surrounding communities extra time to plan for the very real risk the reservoir, the nation's second-largest, will soon run out of water and the flexibility to produce 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 will be held back in Lake Powell itself, as an alternative of being sent to downstream states.
The US Bureau of Reclamation expects the dual 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, in keeping with the bureau, though 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 properties and companies in seven states.
The agency stated in a press release Tuesday's choice was intended to protect "hydropower generation, the power's key infrastructure, and the water provide for the town of 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.
"We've got by no means taken this step earlier than, but the potential threat on the horizon demands prompt action," Assistant Secretary of Water and Science, Tanya Trujillo informed reporters. "We need to work together to stabilize the reservoir before we face a larger disaster."
Lake Powell has dropped round 100 ft in the last three years because 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 energy utility in Web page, Arizona, likened the state of affairs to judgment day.
"We're knocking on the door of judgment day," Hill previously told CNN. "Judgment day being when we don't have any water to present anyone."
The decisions made for Lake Powell also have an effect on its downstream neighbor, Lake Mead, which is the largest reservoir in the country.
Water cuts for many who rely on Lake Mead started in January, and Tuesday's resolution might result in further restrictions.
Lake Mead's water degree is now low enough to show one of the 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 company liable for managing water assets for 2.2 million individuals in southern Nevada, together with Las Vegas.
Officers over the weekend made one other disturbing discovery introduced on by Lake Mead's plummeting water degree: a physique in a barrel police say is a probable homicide sufferer from the 1980s.
"The lake has drained dramatically during the last 15 years," said Las Vegas Metropolitan Police Homicide Lieutenant Ray Spencer. "It's probably that we will discover additional our bodies that have been dumped in Lake Mead" because the water level drops extra.
