The federal government on Tuesday introduced it is going to delay the discharge of water from one of the Colorado River's main reservoirs, an unprecedented motion that will quickly deal with declining reservoir levels fueled by the historic Western drought.

The choice will preserve more water in Lake Powell, the reservoir located at the Glen Canyon Dam in northern Arizona, as a substitute of releasing it downstream to Lake Mead, the river's different primary reservoir.

The actions come as water levels at both reservoirs reached their lowest levels on report. Lake Powell's water stage is at the moment at an elevation of 3,523 ft. If the level drops under 3,490 ft, the so-called minimal energy pool, the Glen Canyon Dam, which provides electrical energy for about 5.8 million prospects within the inland West, will now not have the ability to generate electricity.

The delay is expected to protect operations at the dam for next 12 months, officers said during a press briefing on Tuesday, and will hold practically 500,000 acre-feet of water in Lake Powell. Underneath a separate plan, officials may even launch about 500,000 acre-feet of water into Lake Powell from Flaming Gorge, a reservoir positioned upstream at the Utah-Wyoming border.

Officers said the actions will help save water, shield the dam's means to produce hydropower and provide officers with extra time to determine the way to operate the dam at decrease water levels.

"Now we have by no means taken this step before in the Colorado Basin," assistant Inside Department secretary Tanya Trujillo told reporters on Tuesday. "But the situations we see at this time, and what we see on the horizon, demand that we take prompt motion."

Federal officials final year ordered the first-ever water cuts for the Colorado River Basin, which supplies water to more than 40 million people and some 2.5 million acres of croplands within the West. The cuts have largely affected farmers in Arizona, who use nearly three-quarters of the out there water provide to irrigate their crops.

In April, federal water managers warned the seven states that draw from the Colorado River that the government was contemplating taking emergency action to handle declining water ranges at Lake Powell.

Later that month, representatives from the states sent a letter to the Interior agreeing with the proposal and requesting that short-term reductions in releases from Lake Powell be applied with out triggering further water cuts in any of the states.

The megadrought within the western U.S. has fueled the driest 20 years in the area in a minimum of 1,200 years, with circumstances likely to proceed by way of 2022 and persist for years. Researchers have estimated that 42% of the drought's severity is attributable to human-caused climate change.

"Our local weather is changing, our actions are liable for that, and we've got to take responsible motion to respond," Trujillo said. "We all need to work collectively to protect the assets we have now and the declining water supplies in the Colorado River that our communities rely on."
