Concerningly low amounts of water are flowing from Rocky Mountain snowpack this spring, a summer of drought looms across swaths of the West, and the negotiators tasked with devising a sustainable long-term water plan for the 40 million people who rely on the Colorado River are running out of time. Commissioners from the seven states in the Colorado River Basin — Colorado, New Mexico, Wyoming, Utah, Arizona, California and Nevada — must create a plan that will govern how those states divvy up the river’s water after the current guidelines expire at the end of 2026. As the river shrinks due to drought and climate change, the negotiators must decide who will take less water — and they need to do so in the next few months.

“The way the law of the river is set up, this is a decision that takes the seven states, and there are so many stakeholders and users who depend on that,” said Jennifer Pitt, Colorado River program director at the National Audubon Society. “We are really at their mercy and we are just about out of time.”

The negotiators, who met in Las Vegas this week, have repeatedly said they are committed to finding a consensus solution, but have not yet done so and have already blown past previous deadlines set by federal authorities more than a year ago. JB Hamby, California’s negotiator, said in an interview that the states have been meeting several times a month since December, when tensions between the states burst into public view during a conference. Both the frequency and the tenor of the meetings have since improved, he said.

Those who depend on the river are already dealing with uncertainty: this season’s mountain snowpack is expected to deliver about half the median amount of water to the system’s two major reservoirs, which are already two-thirds empty. Years of drought not balanced by decreases in water consumption have drained Lake Mead and Lake Powell, and aridification fueled by climate change is expected to continue to reduce the flow of the river that makes modern life possible across the Southwest. The Colorado River irrigates more than 5 million acres of farmland — including water supplies for much of the nation’s winter vegetables — and comprises large portions of many Western cities’ water portfolio, said Brad Udall, senior water and climate research scholar at Colorado State University’s Colorado Water Institute.
