Colorado River States Strike a Historic Water Deal

In May 2023, the Biden administration and the three major Lower Basin states — California, Arizona, and Nevada — reached a voluntary agreement to conserve 3 million acre-feet of water from the drought-stricken Colorado River through 2026. The deal, backed by $1.2 billion in federal Inflation Reduction Act funding, compensates cities, water districts, and farm operators for reducing their draws on the river by approximately 13% of their total allocation.

The agreement came after nearly a year of tense negotiations and was hailed as a breakthrough in efforts to stabilize the river system, which serves 40 million people, seven states, and 30 Tribal Nations. Rather than forcing mandatory federal cuts, the deal allowed states to voluntarily reduce consumption in exchange for financial compensation, averting a deeper water crisis driven by prolonged drought and climate change.

The 3 million acre-feet bought with $1.2 billion bridged to a seven state deal that never came: the states missed Interior's November 11, 2025 deadline, per the Colorado Sun, and on August 21, 2026 Washington imposed its own rules. The record of decision cuts Lower Basin deliveries by 1.25 million acre-feet in 2027 and 2028, 760,000 of it from Arizona, and holds Lake Powell releases to 6 to 7 million acre-feet to keep the reservoir above 3,510 feet, per Interior. Nevada sued on August 24, saying the plan could strip up to 213,556 of its 300,000 acre-feet while Upper Basin states face only voluntary goals.
