As Colorado River states await water cuts, they struggle to find agreement on longer-term plans

WASHINGTON (AP) — The federal government is expected to announce water cuts soon that would affect some of the 40 million people reliant on the Colorado River, the powerhouse of the U.S. West. The Interior Department announces water availability for the coming year months in advance so Western cities, farmers and others can plan.

Behind the scenes, however, more elusive plans are being hashed out: how the basin will share water from the diminishing 1,450-mile (2,334-kilometer) river after 2026, when many current guidelines that govern it expire.

The Colorado River supplies water to seven Western states, more than two dozen Native American tribes, and two states in Mexico. It also irrigates millions of acres of farmland in the American West and generates hydropower used across the region. Years of overuse combined with rising temperatures and drought have meant less water flows in the Colorado today than in decades past.

That’s made the fraught politics of water in the West particularly deadlocked at times. Here’s what you need to know about the negotiations surrounding the river.

WHAT ARE STATES DISCUSSING?

Plans for how to distribute the Colorado River’s water after 2026. A series of overlapping agreements, court decisions and contracts determine how the river is shared, some of which expire at the end of 2025.

In 2007, following years of drought, the seven U.S. states in the basin — Arizona, Nevada, California, Colorado, New Mexico, Utah and Wyoming — and the federal government adopted rules to better respond to lower water levels at Lake Mead and Lake Powell. Those are the river’s two main reservoirs that transfer and store Colorado River water, produce hydropower and serve as barometers of its health.
