The federal government on Tuesday introduced it would delay the discharge of water from one of the Colorado River's major reservoirs, an unprecedented motion that will temporarily deal with declining reservoir ranges fueled by the historic Western drought.

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

The actions come as water levels at both reservoirs reached their lowest ranges on report. Lake Powell's water level is currently at an elevation of three,523 toes. If the extent drops under 3,490 feet, the so-called minimal power pool, the Glen Canyon Dam, which supplies electricity for about 5.8 million prospects within the inland West, will no longer be capable of generate electrical energy.

The delay is expected to protect operations on the dam for next 12 months, officials mentioned throughout a press briefing on Tuesday, and can keep almost 500,000 acre-feet of water in Lake Powell. Beneath a separate plan, officials will also release about 500,000 acre-feet of water into Lake Powell from Flaming Gorge, a reservoir located upstream at the Utah-Wyoming border.

Officers mentioned the actions will assist save water, shield the dam's skill to produce hydropower and supply officers with more time to figure out learn how to operate the dam at lower water levels.

"Now we have by no means taken this step before within the Colorado Basin," assistant Interior Division secretary Tanya Trujillo instructed reporters on Tuesday. "However the situations we see at this time, and what we see on the horizon, demand that we take immediate motion."

Federal officials last year ordered the first-ever water cuts for the Colorado River Basin, which provides water to more than 40 million individuals and some 2.5 million acres of croplands in the West. The cuts have largely affected farmers in Arizona, who use nearly three-quarters of the accessible water supply 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 deal with declining water levels at Lake Powell.

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

The megadrought within the western U.S. has fueled the driest two decades in the area in not less than 1,200 years, with situations likely to continue by way of 2022 and persist for years. Researchers have estimated that 42% of the drought's severity is attributable to human-caused local weather change.

"Our local weather is changing, our actions are accountable for that, and we have now to take responsible motion to reply," Trujillo said. "All of us need to work together to guard the resources we now have and the declining water provides within the Colorado River that our communities depend on."
