The West is in the grips of a climate change-fueled megadrought, and Lake Mead — the largest manmade reservoir in the country and a source of water for millions of people — has fallen to an unprecedented low.
According to CNN, The lake’s plummeting water level has exposed one of the reservoir’s original water intake valves for the first time, officials say. The valve had been in service since 1971 but can no longer draw water, according to the Southern Nevada Water Authority, which is responsible for managing water resources for 2.2 million people in Southern Nevada, including Las Vegas.
Across the West, extreme drought is already taking a toll this year and summertime heat hasn’t even arrived yet. After a disappointing winter with very little rain and snow, water officials in Southern California are now demanding that residents and businesses limit outdoor watering to one day a week. It’s the first time they’ve implemented such a strict rule.
“This is a crisis. This is unprecedented,” said Adel Hagekhalil, general manager of the Metropolitan Water District of Southern California. “We have never done anything like this before and because we haven’t seen this situation happen like this before. We don’t have enough water to meet normal demands for the six million people living in the State Water Project dependent areas.”
At Lake Mead, photos were taken Monday to show the eldest of the agency’s three intake valves high and dry above the waterline. “When the lake hit 1060 (feet above sea level), that’s when you could start to see the top of the intake number one,” said Bronson Mack, public outreach officer for the Southern Nevada Water Authority. Lake Mead hit 1,060 feet above sea level on April 4 and stands at 1055 feet as of Wednesday, he said.
As a result, the water authority has begun operating new, low-lake pumping station for the first time — a valve situated deeper at the bottom of Lake Mead. The station, which began construction in 2015 and was completed in 2020, is capable of delivering water with the lake at a much lower level, and was built to protect the region’s water resource in light of worsening drought. “There was no impact to operation’s ability to deliver water,” Mack said. “Customers didn’t notice anything. It was a seamless transition.”
