Arizona opened August with strong pushback to the federal government’s new framework for managing the Colorado River after 2026.
The Bureau of Reclamation’s Final Environmental Impact Statement lays out a 10-year framework for future operations at Lake Powell and Lake Mead. The current operating rules expire after 2026, and the seven Basin states have not reached a long-term agreement on how future shortages should be shared.
Under the federal framework, Arizona, California, and Nevada could face mandatory reductions in Colorado River use. The Department of the Interior said the plan allows Lower Basin shortages of up to 3 million acre-feet, depending on reservoir conditions. The Upper Basin states — Colorado, Utah, Wyoming, and New Mexico — would not face mandatory reductions for now.
Arizona officials and water leaders criticized that approach, saying it places too much of the burden on the Lower Basin and especially on Arizona. Fox 10 reported that the Central Arizona Project, which delivers Colorado River water to central and southern Arizona, raised concerns that the federal framework could lead to deeper cuts for the state. CAP serves cities, farms, and Tribal communities through its 336-mile canal system.
Several Arizona leaders said the state has already conserved significant amounts of Colorado River water and should not be forced to carry the largest share of future reductions. KNAU reported that Arizona officials called on Upper Basin states to do more to share the burden, while Upper Basin officials argued that drought and reduced snowpack already limit the amount of water available to them.
Central Arizona Project President Terry Goddard also criticized the federal plan. KTAR reported that Goddard said the plan requires Lower Basin states to cut water use while Upper Basin states face no mandatory reductions. CAP said it expects the final operating guidelines for 2027 and 2028 to better reflect the Lower Basin proposal, which would conserve more than 3.2 million acre-feet of water through 2028.
The issue is especially important for Arizona because cuts to Colorado River water would not affect every community the same way. ABC15 reported that reductions would hit Valley cities unevenly because Central Arizona Project water is delivered under a priority system. Some communities have stronger priority, stored water, other supplies, or Tribal water leases that may help reduce the impact. Others could be more exposed.
Phoenix said it is prepared for possible Colorado River reductions because of conservation, underground storage, diverse supplies, and long-term infrastructure planning. The city has also joined regional water-sharing efforts meant to help Arizona communities manage shortages.
Infrastructure is becoming a larger part of the state’s water planning. KJZZ reported that Salt River Project opened the Gilbert Road Pipeline, a $25 million project that will help Valley cities access stored groundwater during dry times. The pipeline connects water stored near the Granite Reef Underground Storage Project to the Arizona Canal, making it easier for cities to recover water they banked for shortage conditions.
The SRP project also involved the Salt River Pima-Maricopa Indian Community. KJZZ reported that the pipeline crosses part of the community near Mesa, and President Martin Harvier spoke at the ribbon-cutting, connecting the project to the long history of canal systems in the Valley.
Lake Powell remains one of the biggest concerns. KTAR reported that the reservoir could lose the ability to generate hydropower as early as March 2027 if water levels continue to fall. Glen Canyon Dam provides power for millions of people across the Southwest, and low reservoir levels can also affect dam infrastructure, releases through the Grand Canyon, and downstream operations.
The federal framework has also drawn concern outside Arizona. Nevada officials are reviewing what future cuts could mean for Southern Nevada, while Upper Basin states have said the plan recognizes the difference between water that is available and water that is demanded. NPR and other national outlets reported that the federal plan could shape Colorado River operations through 2036 if the states do not reach a stronger agreement.
The reports show the Colorado River negotiations entering a new phase. The federal government has put forward a framework. Arizona leaders are objecting to parts of it. CAP is warning about legal and practical concerns. Cities are looking at conservation, stored water, and infrastructure. The Basin states still have time to reach agreements, but the federal process is moving forward.
The next step will be the Record of Decision and operating guidelines. Those documents will determine how the framework is applied, including what happens in 2027 and 2028.
What does this mean for CRIT?
For CRIT, the federal framework matters because it deals with the operation of Lake Powell and Lake Mead, which shape much of the Colorado River system.
The reporting also shows how important priority and infrastructure are during shortages. ABC15 reported that future cuts could affect Arizona communities differently based on priority, stored supplies, and Tribal leases. For CRIT, that reinforces the importance of senior rights, clear local water management, and the infrastructure needed to put water to use.
The SRP pipeline story also shows how Tribal lands and regional infrastructure can intersect. The project involved the Salt River Pima-Maricopa Indian Community and highlights how water planning in Arizona often connects cities, Tribal Nations, and long-term storage.
As Reclamation prepares the Record of Decision and operating guidelines, CRIT has a direct interest in how future rules address Tribal inclusion, agriculture, conservation opportunities, infrastructure, and river health.
