Federal Two-Year Plan Cuts Colorado River Water for Arizona, California and Nevada

Core Event
On August 21 2026 the U.S. Department of the Interior, through the Bureau of Reclamation, released the 2027-2028 Operating Guidelines for the Colorado River. The plan mandates that Arizona, California and Nevada collectively reduce water deliveries by 1.25 million acre-feet per year for the next two years. Cuts are allocated as follows: Arizona – 760,000 af, California – 440,000 af, Nevada – 50,000 af. No mandatory reductions are imposed on the upper-basin states. The guidelines also call for an additional voluntary conservation of 700,000 acre-feet over the two-year period.
Background & Context
The Colorado River supplies water to roughly 40 million people and irrigates more than 5 million acres of farmland. A 26-year megadrought has driven Lake Mead and Lake Powell to record-low elevations, exposing the shortfall of the 1922 Colorado River Compact, which allocated 7.5 million acre-feet to each basin based on higher historic flows.
Data & Statistics
- Total mandated cuts: 1.25 million acre-feet per year (? 1.54 billion m³).
- State-specific cuts: Arizona – 760,000 af (? 30 % of its allocation), California – 440,000 af (? 10 % reduction), Nevada – 50,000 af (? 16 % reduction).
- Voluntary conservation target: 700,000 acre-feet over two years.
- Combined reduction (mandatory + voluntary): up to 3.2 million acre-feet (? 3.9 billion m³).
- Reservoir threshold: Lake Powell to be kept at or above 3,510 ft ASL, a 20-foot buffer above the level that would halt Glen Canyon Dam’s hydropower.
Official Statements & Responses
Assistant Secretary for Water and Science Andrea Travnicek highlighted the drought and the need for basin-wide cooperation. Arizona Water Resources Director Tom Buschatzke called the cuts “substantial stability” for 2027-2028. Nevada Governor Joe Lombardo praised the lower-basin’s “proactiveness” in addressing the drought.
Criticism & Opposition
Arizona Governor Katie Hobbs warned that any future doubling of cuts would “devastate” the state’s economy and pledged legal defense of Arizona’s water rights. The Colorado River Indian Tribes and the Gila River Indian Community said the draft guidelines failed to honor tribal water rights and signaled possible legal challenges. Rep. Dina Titus (NV) urged additional measures such as desalination and cuts in the upper basin.
On-the-Ground Reports
Water-resource attorney Cynthia Campbell said most urban customers will not notice immediate changes, but higher water rates and intensified conservation messaging are expected.
Conflicting Reports & Gaps
- Total reduction figure: Some sources cite 1.25 million acre-feet of mandatory cuts, while others reference a 1.6 million-acre-feet combined reduction for 2027-2028.
- Percentage reduction: Outlets differ between a 20 % and 21 % cut for the lower basin.
- Future cut potential: The plan allows for cuts up to 3 million acre-feet per year after 2028, but trigger criteria remain unspecified.
Verbatim Quotes
- “We've been in this 26-year prolonged drought period,” — Andrea Travnicek, Assistant Secretary for Water and Science
- “For 2027 and 2028, the reductions that are now memorialized here will provide substantial stability for folks,” — Tom Buschatzke, Arizona Water Resources Director
What's Next
The Operating Guidelines are reviewed every two years; the Bureau of Reclamation will assess reservoir elevations and may impose deeper cuts if levels continue to fall. The federal government has pledged $350 million for lower-basin water-saving projects and $100 million for upper-basin initiatives, funded by the Inflation Reduction Act. Ongoing negotiations among the seven basin states, tribal nations, and Mexico will determine whether a longer-term, basin-wide agreement can replace the interim plan.
