The Colorado River flows through seven states and provides water to 40 million people. WASHINGTON — Long-term drought has reduced Colorado River system storage to about 36 percent of capacity, and the combination of the lowest snowpack on record and record-breaking March heat has further intensified drought conditions across the Basin. These compounding factors are creating elevated risks to essential water and power infrastructure that supply water to more than 40 million people, underscoring the need for immediate action.

Lake Powell’s water year minimum probable inflow is forecasted at just 2.78 million acre-feet—29% of historical average and one of the lowest on record. Reclamation’s April “ 24 Month Study ” projects Lake Powell may decline to below 3,490 feet—the minimum power pool level—by August 2026 without major intervention. If Glen Canyon Dam declines below 3,490 feet, water releases would be only through the river outlet works, which could cause operational issues, uncertainty for users, downstream impacts, instability in regional power and water supplies, and a reduction in power generation.

Secretary of the Interior Doug Burgum met with Governors for the seven basin states, Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming, and their designees again today to discuss the concerning hydrology and plans for operations.

“I am grateful for the Governors and their teams working diligently to find a solution to the complex challenges created by these unprecedented drought conditions which require immediate action,” said Interior Secretary Doug Burgum. “Interior and Reclamation continue to coordinate with the basin states, tribes, Mexico and basin stakeholders as we make the decisions necessary to operate and protect the system.”

To stabilize the system, Reclamation is moving quickly and initial plans include adding up to about 2.48 maf of water to Lake Powell by moving water from the upstream Flaming Gorge Reservoir and by reducing releases from Lake Powell.

Through the 2019 Drought Response Operating Agreements, Reclamation is intending to release 660,000 acre-feet to 1 maf from Flaming Gorge Reservoir from April 2026 through April 2027. In addition, Reclamation is intending to reduce the annual release volume from Lake Powell to Lake Mead by 1.48 maf—from 7.48 maf to 6.0 maf—through September 2026 by utilizing section 6E of the Record of Decision from the final 2024 Supplemental Environmental Impact Statement for near-term Colorado River Operations.

Together, these actions are expected to increase Lake Powell’s elevation by approximately 54 ft to at least elevation 3500 feet by April 2027. Through the current, ongoing DROA process, the basin states, tribes and partners continue to provide feedback related to the proposed releases. A final decision will be coming next week.

Flaming Gorge Reservoir now holds about 3.1 maf of water, which is 83% full. These actions are expected to lower the reservoir’s elevation by roughly 35 feet over the next year to approximately 59% of capacity. This will have no effect on contracted water rights at Flaming Gorge or Lake Powell. No additional releases from the other upstream initial units of the Colorado River Storage Project Act—Blue Mesa and Navajo reservoirs—are planned at this time, due to their low water levels and poor forecasted inflows.

“Given the severity of the risks facing the Colorado River system, it is imperative that we take action quickly to protect a resource that supplies water to 40 million people and supports vital agricultural, hydropower production, tribal, wildlife, and recreational uses across the region,” said Assistant Secretary - Water and Science Andrea Travnicek. “As we weigh current conditions and prepare for future operations by working with states, tribal nations and stakeholders, the Department of the Interior and Reclamation remain fully committed to taking the actions necessary to reduce impacts on water deliveries, safeguard critical infrastructure, and preserve as much operational flexibility as possible.”

Basin-wide impacts

Reclamation acknowledges that the proposed reduced releases from Lake Powell will accelerate the downstream decline of Lake Mead, with the potential for up to an additional 40% reduction to Hoover Dam’s hydropower generating capacity as early as this fall. Reclamation and its lower basin partners are collaborating to conserve water in Lake Mead and maintain its water levels, even as releases from Lake Powell are planned to decrease.

The initial proposed drought response actions may also impact recreation across multiple sites. At upstream reservoirs, boating access may be reduced earlier in the season than normal. In the Grand Canyon, lower flow rates will affect rafting conditions, and fishing may be more challenging. At Lake Mead National Recreation Area, reduced water levels may further limit boating access. Reclamation is working with reservoir recreation management partners now and as the summer progresses.

The 2026 operational challenges come at a time of transition as the existing agreements that guided the operations of the Colorado River for the last two decades are set to expire at the end of the year. As we approach the new water year on October 1, the seven basin states have not reached consensus on a new operating framework. With time running out, there is a need for extraordinary collaboration for 2027 and beyond. In the absence of a consensus and following the completion of the NEPA process, the Interior Department will be prepared to determine operations for Post 2026 later this summer to provide certainty and stability for the Colorado River Basin.
