The seven U.S. states that make up the Colorado River basin are struggling to agree on how best to manage the river’s water as its supply dwindles due to climate change and a period of prolonged drought. Their negotiations, which are not open to the publicmissed a Feb. 14, 2026, deadline the federal government had established, after which federal officials said they would impose their own plan.

The federal government has not yet done so, but the prospect of such an action is not good news for the nearly 40 million people who depend on the Colorado River for water, energy, agriculture and recreation, nor for the estimated US$1.4 trillion in economic activity the river supports.

We have led or participated in complex water management discussions from the river’s headwaters in Colorado to its delta in Mexico and elsewhere in the arid Southwest and around the world. Even on less contentious issues, the keys to success involve learning together, understanding one another’s interests, working through conflict and developing inclusive solutions for diverse participants. And that works best with an outside facilitator.

The five most common sources of conflict between people are values, data, relationships, interests and structure. The current Colorado River negotiations include all five. We believe a process designed and facilitated by negotiation experts could help break the logjam.

We recognize it can be very hard to reach an agreement when what’s at stake are countless lives, massive amounts of money, enormous quantities of hydroelectric power and not nearly enough water.

But compromise on Colorado River management is possible and, in fact, was achieved to curb California’s water use in the 2000s, to negotiate an interim agreement to coordinate operations at the Lake Mead and Lake Powell reservoirs in 2007, and to enact contingency plans to manage drought in 2019. But this time around, circumstances are different.

Previous Negotiations
The negotiations leading up to those agreements were often facilitated by officials from the U.S. Bureau of Reclamation who focused on reaching broad agreements on general principles and concepts before delving into details. Federal staff also actively guided key agreements and provided the science and computer models to make well-informed decisions. And the states’ negotiators knew the Department of Interior would act unilaterally to make damaging cuts to water supply if states couldn’t come to their own agreement.
