PHOENIX— Today, Arizona Governor Katie Hobbs, California Governor Gavin Newsom, and Nevada Governor Joe Lombardo announced that the Colorado River Lower Basin States have developed a plan to conserve 3 million acre-feet over the next three years to protect the Colorado River system. 

“The Lower Basin Plan is the product of months of tireless work by our water managers to develop an agreement that stabilizes the Colorado River system through 2026,” said Governor Katie Hobbs. “Thanks to the partnership of our fellow Basin States and historic investments in drought funding, we now have a path forward to build our reservoirs back up in the near-term. From here, our work must continue to take action and address the long-term issues of climate change and overallocation to ensure we have a sustainable Colorado River for all who rely upon it.”

“The entire Western United States is on the frontlines of climate change — we must work together to address this crisis and the weather extremes between drought and flood,” said Governor Gavin Newsom. “California has stepped up to make significant cuts to water usage and now, this historic partnership between California and other Lower Basin states will help maintain critical water supply for millions of Americans as we work together to ensure the long-term sustainability of the Colorado River System for decades to come.”

“Nevada has long been a leader in regional water conservation efforts, and we’re pleased to continue leading through this agreement with other Lower Basin States,” said Governor Joe Lombardo. “Through this partnership, we look forward to equitably advancing our mutual goal of conserving our shared water resources. It’s never been more important to protect the Colorado River System, and this partnership is a critical next step in our efforts to sustain this essential water supply.”


The Lower Basin Plan has been submitted to the Bureau of Reclamation with all Seven Colorado River Basin States supporting its evaluation as an action alternative within the Near-Term Colorado River Operations Draft Supplemental Environmental Impact Statement (Draft SEIS).
