Western states face steep Colorado River water cuts

Millions of people across the Southwest will face tighter water supplies after federal officials ordered major reductions from the Colorado River.

Arizona, California and Nevada must cut their combined water use by 1.25 million acre-feet a year in 2027 and 2028. Arizona will make the largest reduction. Mexico will also reduce its share by 250,000 acre-feet under an existing agreement.

The cuts come as the river system faces mounting pressure. Last winter brought record-low snowpack, while years of drought, heavy use and hotter temperatures have drained Lake Mead and Lake Powell. Both reservoirs recently reached their lowest levels in decades.

The new measures offer temporary stability, but they do not settle the long-term dispute. Existing water rules expire in October, and the seven basin states have yet to agree on a permanent replacement.

The latest plan gives communities breathing room, but the river’s deeper problems remain unresolved.
