This summer, America’s water crisis became real

Two high profile Water crisesjuice by Climate change and Industrial excessis built in the United States. From a Texas city facing a drought emergency to a decades-long political crisis coming to a head in states that depend on the Colorado River, water issues in the West will take center stage this summer — and experts tell WIRED that other places should take note and start planning ahead for their future.

In February, after a winter of record temperatures, snow In various mountain ranges across the American West it has reached record levels. March came Even hotterbreaking records in countries of the region.

“What happened in March was unprecedented, astonishing, alarming, and out of this world, frankly — we had temperatures the likes of which we had never seen before and that could not have happened without human-caused climate change,” says Brad Udall, a senior water and climate researcher at the Colorado Water Center at Colorado State University. “We had a bad snowpack that went from bad to terrible in three weeks.”

This melting snow crisis has dire effects on the Colorado River, one of the most important water sources in the West, which provides water to 40 million people in seven states. The river was flowing in some areas in Colorado slowed down considerably Last week, thanks to the early snowmelt this year.

The Colorado River isn’t just an important source of water: it also provides power to more than 25 million people through dams on Lake Powell and Lake Mead, the nation’s two largest reservoirs. Low water levels in these reservoirs cause problems in generating electricity. As of Tuesday morning, Lake Mead He sits At just 17 feet above its record low, hiring In July of 2022.

This record dry season also collides with a decades-long political crisis on the Colorado River. For years, states that draw water from the river have debated how to fairly divide the river’s water supply, as the growth of agriculture and a series of climate-related droughts begin to threaten their long-term water supply. Alfalfa for livestock feed is The largest consumer of water of Colorado, using more water than all the cities along the river combined. Countries are absent Key deadlinesincluding a meeting in February, to renegotiate the 1922 Colorado River Compact, which regulates how water is distributed in the region. Each state gets an annual allotment, and the total amount of water is supposed to be divided equally between the upper basin and the lower basin.

Earlier this month, following a bleak outlook for the summer, the US Department of the Interior stepped in, announcing a new plan. A series of actions It aims to keep Lake Powell’s hydroelectric power running. The government acknowledges that this may reduce Lake Mead’s hydroelectric power as well as water availability in states along the lower part of the river.

With all this chaos, there’s a possibility, Udall says, that this season’s water scarcity could set a historic precedent in the next few years: Upstream states could fail to deliver enough water to lower basin states, violating the 1922 agreement for the first time. This could lead to potential litigation between states.

“The frustrating thing for someone like me is that it’s all so predictable,” Udall says. “Those who kind of have the knowledge, and that includes a lot of people in the Colorado River Basin, have seen something like this coming for a very long time.”
