The federal government just ordered three states to slash the water they draw from the Colorado River, with Arizona taking a 27 percent hit — and it comes as Lake Mead sits lower than it has been in the 90 years since it was built.

Arizona, California, and Nevada will be forced to make deep cuts under a new two-year operating plan released Friday by the Department of the Interior. Arizona gets hit hardest: 760,000 acre-feet shaved off its share, roughly a 27 percent reduction. California loses 440,000 acre-feet, about 10 percent. Nevada takes a 50,000 acre-foot cut, roughly 16 percent. An acre-foot is enough water to supply roughly three families for a year.

The stakes are plain. The Colorado River provides water to roughly 40 million people and irrigates more than 5 million acres of farmland. Lake Mead and Lake Powell — the system's two anchor reservoirs — fell to their lowest combined levels on record last month. Sarah Porter, director of the Kyl Center for Water Policy at Arizona State University, told CNN the reservoirs are sending "a dramatic signal that the system is at risk of crashing, meaning reservoir levels so low that water cannot be delivered from them."

This crisis was decades in the making, and both parties own it. The 1922 Colorado River Compact divvied up 15 million acre-feet per year between upper and lower basin states. The river now averages barely 10 million. The compact was written for a wetter era with fewer people, and Washington never forced a correction. States have blown through deadline after deadline trying to negotiate their own solution. The Interior Department finally stepped in — but only with a stopgap.

The new framework covers just two years, through 2028. Experts say it falls short. Noah Garrison, a water researcher at UCLA's Institute of the Environment and Sustainability, called it a can-kick: "This just kicks the can down the road." He warned the plan leaves stakeholders "locked in endless negotiations." Dr. John Berggren of Western Resource Advocates put it bluntly: "We're going to have to do more."

The Guardian noted that the three lower-basin states could collectively lose up to 3 million acre-feet per year — roughly 40 percent of their supply — depending on conditions. More than 3 million acre-feet of cuts are needed just to bring the basin back into balance. CNN framed the cuts as specific, fixed numbers; The Guardian emphasized that larger cuts loom if dry conditions persist.

Meanwhile, the upper-basin states of Colorado, New Mexico, Utah, and Wyoming face no mandatory cuts under the plan — a disparity that has tensions between the states near boiling and could spark lawsuits.

Celene Hawkins of the Nature Conservancy's Colorado River Program acknowledged the moment: "We are at a time of tremendous change in how we are managing water in this system."

Forty million Americans rationing a basic necessity while the federal government prints money for commitments overseas. The Interior Department's plan buys two years. It does not build a single new reservoir, expand a single supply, or solve the math problem at the heart of the compact. The can is rolling down a road that's running out of pavement.
