Federal Plan Calls for Major Colorado River Cuts in Arizona, California and Nevada
8/1/2026, 11:05:40 AM
Core Event
On July 31 the U.S. Bureau of Reclamation released a Final Environmental Impact Statement proposing mandatory reductions of up to 3 million acre-feet (?130 billion cubic feet) per year for the Lower Basin states—Arizona, California and Nevada—through 2036. The cuts, described as “subject to hydrology,” will be reassessed every two years, with binding operating guidelines expected by October 1. Upper-Basin states are exempt from mandatory cuts but may contribute voluntary conservation.
Background & Context
The Colorado River, a 1,450-mile waterway that supplies more than 40 million people across seven western states, two Mexican states and 30 tribal nations, has been in drought since 2000. Record-low snowpack and rising temperatures have driven Lake Mead and Lake Powell to their lowest levels since 1957, threatening hydropower and municipal supplies. Existing 2007 operating guidelines expire at the end of 2026, prompting federal intervention after years of deadlocked negotiations.
Data & Statistics
- Proposed cuts: up to 3 million acre-feet annually, enough for >25 million people.
- Current Lower-Basin use (2020-24): 6.5 million acre-feet (49 % of total).
- Agriculture consumes ?70 % of river water.
- Reservoir releases: 5 – 12 million acre-feet annually from Lake Powell; storage capacity for conserved water of 8 million (Lake Powell) and 3 million acre-feet (Lake Mead).
- Voluntary Upper-Basin conservation target: 200,000 acre-feet.
Official Statements & Responses
- Doug Burgum, U.S. Interior Secretary, framed the plan as a flexible framework that can adapt to changing hydrologic conditions while preserving opportunities for consensus-based solutions.
Criticism & Opposition
- The Arizona Department of Water Resources called the cuts “devastating” for the state’s water users and economy.
- Governor Katie Hobbs warned the proposal could force “draconian water cutbacks” on Arizona.
- Governor Joe Lombardo of Nevada called the plan “unrealistic” and warned of “devastating economic and environmental impacts.”
- Utah River Commissioner Gene Shawcroft argued that mandatory cuts should be based on hydrology, not demand.
On-the-Ground Reports
- Nancy Caywood, a third-generation farmer in Tucson, said her farm has already been fallowed after previous cuts and further reductions will force additional land to remain unplanted.
- Mike Osborne, deputy director of Marana Water, described a local effort to double groundwater recharge capacity to offset anticipated shortages.
Conflicting Reports & Gaps
- Some outlets cite the proposal as allowing cuts of up to 3 million acre-feet, while others suggest the initial two-year reductions may be roughly half that amount (?1.5 million acre-feet).
- Precise allocation among the three Lower-Basin states remains undisclosed; state-level proposals vary, with California targeting a 12 % reduction, Arizona 31 %, and Nevada 28 % through 2028.
- The detailed two-year operating plan for 2027-2028 has not yet been released.
Verbatim Quotes
- “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
- “We are not running out of water. We’re running out of cheap water,” — Rhett Larson, water law professor, Arizona State University
What’s Next
The Interior Department will issue a Record of Decision and the first two-year operating plan in the coming weeks, setting specific cut volumes for 2027-2028. States may pursue legal challenges, and biennial reviews could adjust allocations as reservoir levels and hydrologic conditions evolve.
