U.S. Sets 10‑Year Colorado River Framework That Could Force Deep Cuts in Lower Basin

Officials say the plan ties mandatory reductions to reservoir levels to protect dam operations, with a Record of Decision and two‑year operating plans pending before Oct. 1.

Overview

  • The Bureau of Reclamation published a Final Environmental Impact Statement on July 31, 2026 that replaces the 2007 guidelines with a 10‑year, hydrology‑responsive framework through 2036.
  • Under the framework the Lower Basin states of Arizona, California and Nevada could face up to 3 million acre‑feet of collective reductions in severe conditions and Lake Powell releases would be managed between 5 and 12 million acre‑feet per year.
  • Federal officials provisionally accepted the Lower Basin’s short‑term offer for 2027–2028 totaling about 3.2 million acre‑feet over two years, but a formal Record of Decision and the detailed two‑year implementation plan are required before changes take effect on Oct. 1.
  • Arizona officials called the FEIS options unacceptable and warned of severe harm to farms, cities and the Central Arizona Project, making litigation a likely near‑term response from states and stakeholders.
  • The plan leaves the Upper Basin free of mandatory cuts while allowing voluntary conservation (about 200,000 acre‑feet per year subject to hydrology), and sets biennial reviews to adjust operations as drought and warming continue to shrink supplies for 40 million people and much of U.S. agriculture.
