"A Painful Deadline Nears as Colorado River Reservoirs Run Critically Low"

"The federal government has told states to agree on urgent water cuts to ensure dams can keep generating power. Researchers say reductions once considered “unthinkable” may be necessary in the long term."

"States in the Colorado River basin are scrambling to propose steep cuts in the water they’ll use from the river next year, in response to a call by the federal government for immediate, drastic efforts to keep the river’s main storage reservoirs from reaching critically low levels.

The request comes with the Southwest still in the grip of a severe two-decade drought that shows no signs of letting up. And it comes on top of earlier, less desperate, efforts to keep more water in the two reservoirs, Lake Mead and Lake Powell, including a first-ever shortage declaration last year that cut water to farmers in Arizona.

The call to conserve up to an additional 4 million acre-feet of water, an amount equal to about one-third of the Colorado’s current annual flow, is just for 2023. But the long-term outlook for the Colorado is bleak, as climate change continues to affect runoff into the river and reduces the likelihood of a series of wet years that could end the drought."
