PRESS STATEMENT

ADWR statement on Reclamation’s Final Environmental Impact Statement for Future Colorado River Operations

FOR IMMEDIATE RELEASE: July 31, 2026                                             

For many months it has been clear that the direction of Colorado River negotiations has been an exercise in lowering expectations, particularly for a long-term, seven-state agreement on operating this vital river system. It was that increasingly bleak scenario that prompted the three Lower Basin states of Arizona, California and Nevada to step forward with our proposal to help stabilize Lake Powell and Lake Mead with more than three million acre-feet of water savings over a two-year period.

While the FEIS just released by the Department of the Interior does nothing to elevate expectations around a coherent seven-state plan for shared sacrifice, it includes an analysis that allows the adoption of many of the core elements of the Lower Basin proposal. We will continue to work with the federal government, as well as with our tribal, agricultural and municipal partners in Arizona, and the other Colorado River Basin states, to make river operations work for the betterment of all.

The FEIS contains a framework that includes sideboards that are unacceptable for the state of Arizona including reductions in the Lower Basin of up to 3 million acre-feet per year, in priority. Such reductions would devastate Arizona’s water users and its economy. The FEIS framework also fails to include any Upper Basin reductions or sufficient use of water stored in the Upper Initial Units (reservoirs above Lake Powell).

A forthcoming Record of Decision and operating guidelines will provide the details for operations through 2028 and a framework for an additional eight years of operations. We hope to see those documents provide for operations in 2027 and 2028 consistent with the May 1 Lower Basin Proposal, including sharing reductions among the three Lower Basin states (Arizona, California, and Nevada) of 1.25 million acre-feet in each year, as well as an additional commitment of 700,000 acre-feet of system conservation water.

ADWR will continue to work to complete the agreements necessary to implement the Lower Basin Proposal while preserving Arizona’s legal rights.

We will provide additional statements and opportunities for interviews when Interior releases the Record of Decision and the operating guidelines.

A Joint ADWR/CAP Statement On CO River Shortage Preparedness

On By azwaternews1 Comment

Stronger Together

As the drought in the Colorado River Basin extends beyond its 20th year, we anticipate the first-ever shortage declaration on the Colorado River. The shortage will result in a substantial cut to Arizona’s share of the river, with reductions falling largely to central Arizona agricultural users.  These reductions are painful, but we are prepared. We have long understood the risks to Arizona’s Colorado River supplies and have been planning for decades, including the successful efforts to create a Drought Contingency Plan for the Colorado River system in 2019. 

It’s important to note that a shortage means a reduction in the Colorado River supply available to Arizona. While we may have less water coming to Arizona from the Colorado River in 2022, the river will continue to be a vital source of water for generations to come.

In 2021, the river is currently operating in a “Tier Zero” status, requiring the state to contribute 192,000 acre-feet of Arizona’s 2.8 million acre-foot annual entitlement to Lake Mead. This contribution is coming entirely from the Central Arizona Project (CAP) system. 

Based on the current hydrology, it is likely that the U.S. Bureau of Reclamation will elevate the shortage level to a “Tier 1” in 2022. This would require Arizona to reduce uses by a total of 512,000 acre-feet, again, borne almost entirely by the CAP system. While significant, the high priority CAP water supply for cities and tribes is not affected due to the implementation of agreements among Arizona water users.

We are prepared for Tier 1 reductions because Arizona water users have been working collaboratively for many years to protect our Colorado River water supply.

Specifically, the seven states in the Colorado River Basin and the U.S., and the Republic of Mexico, developed plans for managing the Colorado River, known in the U.S. as the Drought Contingency Plan (DCP), which lasts until 2026. Arizona prepared a unique and innovative way to implement the plan in Arizona through its DCP Steering Committee. 

The DCP Steering Committee, which included more than 40 representatives of tribes, cities, agriculture, developers, environmental organizations, and elected officials, worked collectively to share the risks and benefits of the DCP.  Arizona’s DCP implementation plan represents the best of Arizona water management: collaboration, cooperation, and innovation. 

The plan shares resources and mitigates the impacts of shortage reductions.  In the plan, some are committing to leaving extra water in Lake Mead to reduce future risks, while others are sharing water with the most severely impacted of the state’s water users, central Arizona agriculture Together these efforts reduce the pain of the near-term reductions while addressing risks of future shortages.  The result is the Arizona water community is prepared, even in the midst of a decades-long drought.

The actions taken by Arizona’s water-community stakeholders, legislature and by Governor Ducey manage the immediate risk to supplies on the Colorado River, providing time while we develop new rules and programs to sustain the river after 2026.

As we face the prospect of a hotter and drier future, we are confident that with our long history of successful collaboration among our diverse stakeholders – agriculture, tribes, cities, environment, and industry, we will continue to find innovative and effective solutions to sustain Arizona’s Colorado River supply.
