Drought Decided Where the Feds Cut Western Water

In March 2026, the Colorado Basin River Forecast Center released a number that would dictate more federal water policy than any executive order or campaign promise. Spring runoff into the Colorado River was projected at 36% of the historical median: 2.3 million acre-feet instead of the usual 6.4 million, the fifth-lowest forecast since 1963. At that level, Lake Powell risked dropping below the intake tubes that feed Glen Canyon Dam's hydroelectric turbines by August. ^[1]

The Colorado headwaters are the worst this water year; they’re well below normal. — Cody Moser

That number, not any political doctrine, is what forced the Interior Department's hand. Over the following four months, the administration moved from urging the seven basin states to reach a voluntary agreement to imposing mandatory cuts of up to 3 million acre-feet annually on the Lower Basin: Arizona, California, and Nevada. The cuts far exceeded the roughly 1 million acre-feet those states had volunteered in May, when they proposed reductions explicitly to avoid federal intervention. ^[2][3]

That’s us, that’s Arizona, and potentially CAP going to zero. — Tom Buschatzke

Arizona's water director Tom Buschatzke made the stakes plain.

Given the risk and uncertainty facing the Basin, these elements are designed to provide stability while allowing flexibility to incorporate consensus-based recommendations as they develop. — United States Bureau of Reclamation

He was referring to the Central Arizona Project canal that supplies Phoenix and Tucson. When the final framework landed in late July, Arizona Governor Katie Hobbs condemned it.

That challenge is shared across the Basin, and addressing it requires specific, measurable reductions in water use by every state. — Jb Hamby

California's JB Hamby, by contrast, accepted the math.

The proposal responds to a fundamental reality: the Colorado River no longer reliably produces enough water to support all the uses and expectations built around it. — Jb Hamby

The framework left Upper Basin states — Colorado, Wyoming, Utah, New Mexico — with only voluntary targets, a structural asymmetry that split the basin into two camps of grievance. ^[4] So far, this looks like a story of federal enforcement: the states could not agree, so the government stepped in. But look at what the same administration was doing everywhere the water math was not existential. In December 2025, President Trump signed an executive order titled "Putting People over Fish: Stopping Radical Environmentalism" that increased water deliveries to California's Central Valley agricultural districts by 130,000 to 180,000 acre-feet. ^[5]

strengthen California's water resilience. — Doug Burgum

The same administration that was imposing scarcity on the Colorado River was releasing abundance to Central Valley farmers. The difference was not the science. It was that the Colorado River was running dry and the Central Valley's political constituency was not. The pattern holds across two more basins. In Colorado, the Biden-era Bureau of Reclamation had committed $40 million in federal funding toward a $99 million purchase of Shoshone water rights, a deal designed to keep water in the Colorado River rather than diverting it. The Trump administration froze that money. ^[6]

The Trump Administration must now heed the bipartisan, statewide support and release the already-approved $40 million in federal funding to get this project across the finish line. — Michael Bennet

On the Columbia River, the administration canceled a $1 billion salmon restoration agreement with tribes, part of the same "Putting People over Fish" order. A federal judge, Michael Simon, ordered the protections reinstated. ^[7]

One of the foundational symbols of the West, a critical recreational, cultural, and economic driver for Western states, and the beating heart and guaranteed resource protected by treaties with several Native American tribes is disappearing from the landscape. — Sam Simon

The administration was not enforcing a coherent water doctrine. It was imposing cuts where the river left no choice, releasing water where it did, and blocking conservation and environmental protections until courts intervened. Physical scarcity was the discriminating variable. Burgum's own rhetoric preserved the language of consensus.

This framework provides the flexibility to respond to changing hydrologic conditions while preserving the opportunity for the Basin States to continue working toward durable, consensus-based solutions. — Doug Burgum

But no state appears to believe it. Colorado Attorney General Phil Weiser had already warned in January, after a failed four-day meeting in Salt Lake City.

If we can’t get a deal — and I’m committed to not getting a bad deal just to get a deal — you’re 100% right, Senator, we’ll be in litigation. — Philip J. Weiser

Arizona hired the elite law firm Sullivan & Cromwell in March and established a $3-to-4-million legal fund. ^[8] The imposition fractured both sides of the basin into opposition. The legal combat extends well beyond the Colorado. Tribes and states are suing over dam operations on the Columbia and the Eel River, accusing the federal government of ignoring historical water rights. ^[9] The largest tribal water settlement in U.S. history, a $5 billion deal for the Navajo, Hopi, and San Juan Southern Paiute nations, remains stalled because Upper Basin states are blocking it and the administration refuses to approve it without their consent. ^[10] There, the federal government is deferring to state consensus rather than imposing a solution. It is the opposite of the Colorado River posture, and a reminder that the administration's approach is not enforcement but selectivity. Every one of these decisions — imposing cuts, increasing deliveries, freezing conservation funding, rolling back environmental protections — has drawn lawsuits from states, tribes, or courts. The throughline is not a shift from consensus to enforcement. It is that drought decided where the federal government became the decider, and politics decided everywhere it could. That distinction, not the rhetoric of consensus or enforcement, is what the lawsuits are actually fighting over.
