Federal Plan Proposes Up to 40% Colorado River Water Cuts Amid Drought

New Federal Water-Sharing Plan Targets Lower-Basin States
The U.S. Bureau of Reclamation proposed a 10-year plan that could cut water deliveries to Arizona, California and Nevada by up to 3 million acre-feet per year—roughly a 40 % reduction. It calls for releases from Lake Powell to Lake Mead of 5-12 million acre-feet, reviewed biennially.
Drought Context and Expiring Basin Agreement
Lake Mead and Lake Powell have fallen to historic lows after a decade of drought and over-use. The 20-year water-sharing framework governing the Colorado River Basin since 2007 ends in 2026, leaving seven states without a binding rule. The lower-basin states previously offered a voluntary 1.6 million acre-feet cut, far less than the federal proposal.
Stakeholders and Their Positions
Tom Buschatzke, Arizona water-resources director, warned the plan could cut Central Arizona Project flows to zero. The Bureau of Reclamation issues the proposal. Conservation groups—Family Farm Alliance (Samantha Barncastle), San Diego County Water Authority (Dan Denham) and Trout Unlimited (Sara Porterfield)—push for long-term federal investment. UA researcher Sharon Megdal called the two-year renewal schedule perplexing.
Projected Reductions and Reservoir Impacts
A 3 million acre-feet cut could serve 6-9 million households, exceeding Arizona and Nevada’s combined demand. The planned 5-12 million acre-feet releases are below the pre-2020 average of 8.23-9 million and beneath the current 6 million flow, highlighting depleted storage.
Government Statements
The Bureau of Reclamation said the plan is “designed to provide stability while allowing flexibility to incorporate consensus-based recommendations as they develop.” It noted cuts will follow the “priority of the law of the river” in the 1922 Colorado River Compact, which gives California senior rights.
Criticism and Uncertainties
Sharon Megdal called the two-year renewal “perplexing” and asked why the basin would “set themselves up for that,” noting ongoing negotiations. Buschatzke warned the plan could reduce Central Arizona Project deliveries to zero, threatening municipal water security.
Conflicting Data and Gaps
One source lists the release range as 5-12 million acre-feet; another reports releases already at 6 million acre-feet this year. The biennial review method and how it will align state-offered cuts with the federal target remain unclear.

Outlook
The plan will be reviewed every two years, allowing adjustments as lake levels change. Conservation groups urge Congress to fund long-term infrastructure upgrades and voluntary conservation. Ongoing negotiations among the seven basin states will decide if the proposal becomes binding or is replaced.
