Key Points
- The U.S. Bureau of Reclamation is now seeking a 10-year water-sharing plan for the Colorado River states, adjusting cutbacks every two years.
- A worst-case scenario being modeled could slash water shares for Arizona, California and Nevada by 40%.
- The Lower Basin states have proposed their own conservation plan, which could cover the first two years of the new federal framework.
Unable to get Colorado River states to hash out a new 20-year deal to share in worsening water shortages, the U.S. Bureau of Reclamation has told them it’s now aiming for a 10-year plan with prescribed cutbacks to be reassessed every two years. Federal officials informed the seven states of their new preference late last week, and Arizona’s lead negotiator made it public on Wednesday, May 13, during a meeting of a committee representing the cities, tribes and other water users who meet to develop a unified state position.
The shift to what could effectively become five two-year plans carries both opportunities and risks for Arizona. On the one hand, state Water Resources Director Tom Buschatzke said, it means a proposal that the Lower Basin states — Arizona, California and Nevada — recently submitted to boost their conservation through 2028 could cover the first two-year term if federal officials agree. That would keep water moving through the Central Arizona Project Canal, an economic lifeline that is at risk under some other scenarios. On the other hand, a move to bite-size plans “has us in a room negotiating for the next 10 years,” Buschatzke said at a meeting of the Arizona Reconsultation Committee. “That’s not something that creates the certainty that we’ve heard some people desire.”

New rules are necessary because the shortage-sharing guidelines that covered the last 20 years expire this fall — and because the river keeps shrinking along with a paltry snowpack in the Rocky Mountains. A deepening shortage has increased the stakes, keeping a consensus deal out of reach…In pitching their new 10-year “framework,” federal officials also informed the states that they intend to at least model the potential effects of a 3 million acre-foot annual reduction to what the three Lower Basin states could pull from Lake Mead. That worst-case scenario would slash 40% from what the century-old Colorado River Compact promised those Lower Basin states, and it could dry up the CAP Canal. It’s nearly twice the reduction that those states offered in their recent proposal…A 10-year program with a broad menu of potential guidelines that update every two years allows flexibility to adapt to both the changing hydrology and the potential for a political breakthrough on a consensus deal, [Alex] Smith said.
