The Colorado River’s next operating plan is now official, but the larger fight over the river’s future is still unsettled.
On Aug. 21, the Department of the Interior finalized the 2027–2028 Operating Guidelines and Record of Decision for future Colorado River operations. The decision sets the near-term rules for Lake Powell and Lake Mead after the current operating agreements expire in 2026.
Under the plan, Arizona, California, and Nevada will reduce their use of Colorado River water by 1.25 million acre-feet each year in 2027 and 2028. If the Lower Basin states use their proposed sharing agreement, Arizona would take the largest reduction at 760,000 acre-feet per year. California would reduce use by 440,000 acre-feet, and Nevada would reduce use by 50,000 acre-feet.
The plan also calls for at least 700,000 acre-feet of additional voluntary conservation over the two-year period to help protect the system.
Arizona officials said the final decision gives the state some short-term certainty, but it does not resolve the longer-term issue. ADWR said the federal decision avoids the most severe near-term reductions that had been discussed earlier, but the larger framework for years three through 10 remains a concern.
KJZZ reported that Arizona will still take the biggest cuts under the new plan. The reductions are expected to affect Central Arizona Project supplies, which serve cities, farms, and some Tribal communities in central and southern Arizona. Central Arizona Project users are more exposed because CAP holds junior-priority Colorado River rights.
CRIT and other Tribal leaders also raised concerns about the federal process. ICT reported that the Colorado River Indian Tribes and the Gila River Indian Community pushed back on the federal plan, saying Tribal governments were not sufficiently included in the decision-making process. ICT reported that CRIT holds water rights to more than 23% of Arizona’s Colorado River allocation, making the Tribe one of the largest Colorado River water rights holders in the state.
Arizona Digital Free Press also reported that CRIT asked Reclamation to delay the Record of Decision to allow more time for review and government-to-government consultation. CRIT said decisions about Lake Powell and Lake Mead must respect senior water rights, federal trust responsibilities, and meaningful Tribal consultation.
The federal decision came as the river’s two largest reservoirs remained at historic lows. AP reported that Lake Powell hit a record low, threatening water and electricity supplies for millions of people. The low levels at Lake Powell and Lake Mead continue to raise concerns about hydropower, reservoir operations, and future water deliveries.
Those power concerns are tied directly to agriculture. The Arizona Farm Bureau reported that farmers are asking where they will turn if the hydropower they rely on becomes less available. Irrigation districts and farms depend on power to move water, and higher energy costs can increase the cost of producing crops.
Arizona cities are also preparing for more expensive water. Fox 10 reported that Colorado River cuts could drive up water prices as cities invest in infrastructure, wells, conservation programs, and alternative supplies. Gilbert has been one example. ABC15 reported that the town is preparing for less Colorado River water before expected 2027 cuts, including work to secure backup supplies and expand water infrastructure.
Arizona is also looking beyond conservation. KJZZ reported that a state agency advanced partnership projects with California and Mexico that could increase Arizona’s water supply. Those ideas include projects that would generate or conserve water elsewhere in exchange for benefits to Arizona’s Colorado River supply.
At the same time, KJZZ reported that Arizona’s water systems received a “C” grade from the American Society of Civil Engineers. The report said larger cities tend to be better prepared, while smaller and rural communities often face greater infrastructure challenges. That difference matters as shortage planning becomes more dependent on storage, treatment, wells, and delivery systems.
Together, the week’s reporting showed that the 2027–2028 plan gives the Lower Basin a short-term path, but not a complete solution. Arizona avoided the deepest immediate cuts, but still faces the largest reduction. CRIT and other Tribes are raising concerns about inclusion and senior rights. Reservoir levels remain low. Cities and farms are preparing for higher costs. The larger question of how the river will be managed after 2028 remains open.
For CRIT, this week’s Basin Brief is directly connected to senior water rights, Tribal sovereignty, and the future operation of the Colorado River system.
CRIT holds senior Colorado River rights, which places the Tribe in a different position than junior-priority users. But federal decisions about Lake Powell, Lake Mead, shortage rules, and conservation programs still shape the broader system where those rights are exercised.
The ICT and Arizona Digital Free Press reporting are especially important for the CRIT community because they focus on CRIT’s concerns with the federal process. The issue is not only how much water is reduced in 2027 and 2028. It is also whether Tribal governments with senior rights are meaningfully included before federal decisions are finalized.
The agriculture and hydropower reporting also matters because CRIT is a major agricultural water user along the Colorado River. If low reservoir levels affect power costs, pumping, deliveries, or agricultural planning, those issues can become part of the larger Basin conversation.
The city infrastructure reporting shows that water security depends on more than legal rights alone. Communities are investing in wells, treatment, storage, and conservation to prepare for less Colorado River water. For CRIT, senior rights remain central, but long-term planning, delivery systems, and local management are also important.
CRIT’s Water Code and Water Resiliency Act provide a local framework for managing Tribal water resources as Basin conditions change. The Tribe’s Personhood Resolution also reflects CRIT’s cultural and environmental connection to the Colorado River as a living system.
