Im John Dankosky, and now its time to check in on the state of science. "Arizona is, to a greater or lesser degree, selling water to California," CAP attorney said of the later-killed deal. The Glen Canyon Dam forms Lake Powell and the Hoover Dam forms Lake Mead. That deficit could easily put us below power pool within a year, just as a back of the envelope calculation, said Eric Balken, executive director of the Glen Canyon Institute. Water levels have been getting lower and lower, and for the first time ever, a shortage seems almost certain. The basin is made up of portions of Colorado, Wyoming, Utah, New Mexico, Arizona, Nevada and California. Even hardy desert plants, the ones well-adapted to water scarcity, have struggled. Riparian rights do not entitle a water use to divert water to storage in a reservoir for use in the dry season or to use water on . He spent two years at Aspen Public Radio, mainly reporting on the resort economy, the environment and the COVID-19 pandemic. For context, on the scale of no drought to worst drought, theres no category that captures conditions more dry than exceptional. So water from the Colorado River is now pumped across the state of Arizona via the Central Arizona Project (CAP). Lake Oroville (of the enormous spillway failure fame) and Lake Shasta, two of California's largest reservoirs, are at critical levels. Youre hearing a lot more now, especially because the interior secretary, Deb Haaland, is herself a member of a Native American tribe and has put a lot of emphasis on bringing tribes to the table, making tribal consultation a big part of the Biden administrations priorities. When its needed its released to Lake Mead and the three Lower Basin states. The pattern element in the name contains the unique identity number of the account or website it relates to. We'll assume you're okay with this, but you can opt-out if you wish. In an average year, Lake Powell gets enough water that it can release a bit more 8.23 million acre-feet a year. It stores water as part of the Colorado River Compact and produceselectricity through the hydroelectric turbines in Glen Canyon dam. Lakes in the Colorado River Basin are drying up and losing water, with severe water cuts now expected across four states - the start of a water crisis in the West. John Dankosky works with the radio team to create our weekly show, and is helping to build our State of Science Reporting Network. Lake Powell, the nation's second-largest reservoir and one thatprovides water and power to millions of people in southern California, has reached its lowest levels since its first filling in the 1960s. One acre-foot generally provides enough water for one to two households for a year. "That means that due to climate change, it is more likely that we will see [more] extreme heat waves". 2002, 2018 and 2021 are the most intense dry periods on record for the basin. You would have to go back to April of 1937, also twoyears into its initial filling, to find levels that low. This Statista chart shows the share of the continental United States' area under different levels of drought between 2018 and 2022. And what does that mean for the users on the river? And there is some evidence that this dry period would have happened without our greenhouse gas emissions. a study published in the journal Science said the current dry period in the Southwest is one for the record books, and that its "megadrought-like trajectory" is fueled by natural variability superimposed on . So when Lake Mead declines, certain policy triggers are put in place. A drought that has gripped the Southwest is creeping the nation's two largest reservoirs toward a dead pool, which would have catastrophic consequences for water users in the Colorado River's lower basin. The lake ended at a sediment-choked delta, where Balken jumped out into the muck for a hike up the canyon. Water management requires planning for the future. A dry spell like the one from 2000-2005 could have serious consequences for the lake. "I've been here since 2007 and obviously this is way lower than I've ever seen it.". Institute Executive Director Eric Balken said taking such a step would better position stakeholders to address the drought on their own terms rather than simply running out.

The fact that they're becoming involved in this manner points to real concerns that they must have and they must view the situation as one of extreme difficulty that requires them to act more directly. "Its hard to overstate how important the Colorado River is to the entire American southwest.. The vast stripe rimming Powell is a testament to how far its level has dropped since 2000, when the Colorado's flows began a steady decline in response to persistent drought, warming temperatures. Climate change is driving more than two decades of drought across the region, and making it increasingly unlikely that Lake Powell will ever climb back to previous levels. The Lower Basin states of Arizona and Nevada have begun to see their deliveries from the river curtailed. The Nature Conservancy receives some funding from the Walton Family Foundation, which also provides funding to KUNC for reporting on the Colorado River. Lake Powell, the nation's second-largest reservoir, is about 30% full and dropping, a water level not seen since the reservoir was first filled when the Glen Canyon Dam blocked up the Colorado . Frankel criticizes water managers for their inaction in the face of those trends. And data updated Monday from the California Department of Water Resources' tracker show the reservoir climbing to 60%, still below historical levels for February 72% but significantly higher than it had been.

An official shortage declaration from the federal government could come as early as this year, as Lake Mead is currently projected to be below 1,075 feet in elevation at the end of 2021. LUKE RUNYON: Sure, so much of the attention in the basin goes towards the rivers largest reservoirs, which also happen to be the biggest reservoirs in the entire United States. Applying data from three droughts from a 25-year period starting in 1988, it predicted that even with little new growth in that basin, a moderate drought would trigger shortages of 350,000 to 500,000 acre-feet. The big question is how water managers will divvy up a shrinking supply to feed a growing region. The reservoir is integrating all the problems we have, all the challenges we face show up in that one number, in that one place, he said. Some of Americas largest cities depend on the water from Lake Mead. The Colorado River cuts through dry land that was once covered by Lake Powell on September 7, 2022, near Hite, Utah.

As the drought continues and global warming evaporates water supplying the reservoirs, each reservoir isn't far from dead pool, which is when the water level is too low to flow downstream or power the turbines that provide hydroelectric power. According to the National Park Service, contaminants from the newly exposed shorelines are reentering warm, shallow areas and becoming more concentrated. Hes also been a long-time guest host on Science Friday. 40 fun events happening in Tucson this weekend Feb. 23-26 , Opinion: Help protect Lake Mead and Colorado River water, Colorado River runoff forecast keeps dropping, Warm weather reducing Colorado River runoff, study finds, Feds back off from Lake Mead water demand, Businesses, residents paid to save water in this Arizona valley, Tucson to leave nearly 20% of its CAP water in Lake Mead, 'Toilet to tap' water treatment will soon be legal in Arizona, officials say, Big snowstorms put Colorado River drought plan on ice, Colorado River tops group's 'endangered' list again, CAP-California water deal that Arizona nixed provokes ongoing conflict, Water bailout?

He has mostly covered environmental stories since 2005, focusing on water supplies, climate change, the Rosemont Mine and the endangered jaguar. Officials have already taken some stopgap measures to avert the lake getting down to the pivotal 3,490-foot mark. If the reservoirs reach dead-pool levels, more than a million people using the electricity could be required to find new power sources. There is also 29 federally-recognized tribes in the basin, of which 10 of those tribes hold a significant amount of water rights from the river. "You might not see the lush lawns of today and endless fields of alfalfa, but you will see thriving communities and agricultural regions. Its impossible to even guess the odds of the Colorado Basin getting another six-year arid spell any time soon, said Udall and another longtime Colorado River researcher, Connie Woodhouse, a professor in the University of Arizonas School of Geography and Development. All rights reserved. And you know, thats way beyond any sort of voluntary conservation that Arizona has done up until this point. These reservoirs are as empty now as when they started filling Glen Canyon Dam in the 1960s, said John Fleck, director of the University of New Mexicos water resources program.
