Lake Powell’s water level is the lowest it’s been in decades, and the latest 24-month projections from the Arizona and Utah reservoir show that it’s likely to drop even further — below a critical threshold of 3,525 feet by next year.
Camille Touton, a veteran congressional water policy adviser, has been nominated to lead the agency that oversees water and power in the U.S. West.
President Joe Biden on Friday nominated Touton to be the next commissioner of the U.S. Bureau of Reclamation. If confirmed, the Nevada native will be a central figure in negotiations among several states over the future of the Colorado River.
Drought, climate change and demand have diminished the river that supplies 40 million people, and the agency is expected to mandate water cuts for the first time in 2022.
Record-breaking heat and historic drought in the U.S. West are doing little to discourage cities from planning to welcome millions of new residents in the decades ahead.
From Phoenix to Boise, officials are preparing for a future both with more people and less water, seeking to balance growth and conservation. Development is constrained by the fact that 46% of the 11-state Western region is federal land, managed by agencies like the U.S. Forest Service and Bureau of Land Management that are tasked with maintaining it for future generations.
A heat dome is baking Arizona and Nevada, where temperatures have soared past 115 degrees this week and doctors are warning that people can get third-degree burns from the sizzling asphalt.
At Lake Mead, which supplies water for 25 million people in three southwestern states and Mexico, water levels have plunged to their lowest point since the reservoir was filled in the 1930s. In California, farmers are abandoning their thirstiest crops to save others, and communities are debating whether to ration tap water.
Water levels in the Colorado River are a lot lower than normal reducing the water coming into Lake Powell and Lake Mead, according to the Bureau of Reclamation. The level of water in the lake determines how much water will be delivered in the region.
“The reclamation who oversees the operation for the river is forecasting a shortage on the river for next year,” said Kelly Rodgers with the San Diego County Water Authority. “They are predicting a shortage in 2022.”
Rodgers said states such as Arizona and Nevada will see the difference, but not as much in California because agencies such as SDCWA have taken steps to diversify their water supply and have built storage reservoirs and other facilities.
The reservoir created by Hoover Dam, an engineering marvel that symbolized the American ascendance of the 20th Century, has sunk to its lowest level ever, underscoring the gravity of the extreme drought across the U.S. West.
Lake Mead, formed in the 1930s from the damming of the Colorado River at the Nevada-Arizona border about 30 miles east of Las Vegas, is the largest reservoir in the United States. It is crucial to the water supply of 25 million people including in the cities of Los Angeles, San Diego, Phoenix, Tucson and Las Vegas.
Trees are dying. Riverbeds are empty. Lake Mead’s water level dropped to its lowest point in history, and Utah’s governor asked residents to pray for rain. Water is increasingly scarce in the Western U.S. — where 72 percent of the region is in “severe” drought, 26 percent is in exceptional drought, and populations are booming. Insufficient monsoon rains last summer and low snowpacks over the winter left states like Arizona, Utah and Nevada without the typical amount of water they need, and forecasts for the rainy summer season don’t show promise.
A key reservoir on the Colorado River is expected to dip to its record low Thursday in the latest showing of the drought’s grip on the region.
The surface elevation of Lake Mead along the Nevada-Arizona border is projected to be at 1071.61 feet (326.63 meters) — a measure that was hit in 2016. It’s the lowest level since Lake Mead was filled in the 1930s.
The backdrop for the legislation was set hundreds of miles away from Carson City, where the Colorado River meets Lake Mead and the Hoover Dam outside of Las Vegas.
Over the past two decades, Lake Mead, which holds nearly all of Las Vegas’ water, has dropped more than 100 feet amid drought and overuse. In response, federal regulators expect to declare the first-ever shortage for the Colorado River next year, triggering cuts to Arizona and Nevada’s allocations.
Scientists are calling it a “mega-drought” brought on by climate change. The latest U.S. Drought Monitor Map shows large areas of the Southwest are “exceptionally dry,” the worst category. It’s taking a dramatic toll on the Colorado River system that provides water to 40 million people in seven states — and may force the federal government to make a drastic and historic decision. For more than eight decades, the iconic Hoover Dam has relied on water from Nevada’s Lake Mead to cover up its backside. But now, at age 85, it finds itself uncomfortably exposed. Much of the water the dam is supposed to be holding back is gone.
