Colorado River water plan cuts Nevada's share, reshapes Lake Powell management

Colorado River Nevada water cut Lake Powell Bureau of Reclamation water allocation

The U.S. Bureau of Reclamation released a Final Environmental Impact Statement on July 31 that sets a 10‑year operating framework for the Colorado River system from 2027 through 2036. The plan proposes mandatory consumptive‑use reductions of up to 3 million acre‑feet per year for the three Lower Basin states—Arizona, California and Nevada—far larger than the 1.6 million acre‑feet the states originally offered.

Under the new rules Nevada will give up about 50,000 acre‑feet of water each year for the next two years, roughly a third of its allocated 300,000 acre‑feet and well above the 198,000 acre‑feet it actually used last year. After 2028 any deeper cuts will be allocated by seniority, protecting older water rights first. The framework is intended to keep Lake Powell and Lake Mead above critical elevations, preserving water deliveries and hydroelectric generation at Glen Canyon Dam.

Nevada Governor Joe Lombardo warned the plan “imposes unrealistic reductions” that could have “devastating economic” effects, while Arizona officials argue the Lower Basin is shouldering too much of the burden. The federal proposal follows years of failed negotiations among the seven Colorado River Basin states and includes public‑comment input from thousands of stakeholders.
