Governor Hobbs Intervenes in Federal Colorado River Water Lawsuit as AG Mayes Urges Pause on Valley AI Data Center Expansion

Arizona Intervenes in Federal Litigation to Protect Critical Colorado River Water

PHOENIX, Arizona — Taking decisive legal action to protect long-term water security across the desert Southwest, Arizona Governor Katie Hobbs and the Arizona Department of Water Resources (ADWR) announced the state’s formal intervention in federal litigation regarding Colorado River water allocations in October 2026. The legal filing seeks to enforce federal delivery obligations to Lake Mead and shield Arizona municipalities, tribes, and agricultural districts from disproportionate, unmandated water reductions.

Governor Hobbs underscored that defending Arizona’s statutory rights ensures predictable water supplies for the growing Phoenix metropolitan region while state water managers negotiate sustainable, post-2026 basin-wide conservation frameworks with neighboring Colorado River basin states.

Attorney General Kris Mayes Calls for Statewide Pause on AI Data Centers

Concurrently across the Valley, Arizona Attorney General Kris Mayes hosted community town halls in Mesa and South Phoenix to address intense resident pushback regarding hyperscale artificial intelligence data centers. Highlighting severe water cooling demands, surging electrical grid strain, and persistent industrial noise in residential neighborhoods like Ahwatukee, Mayes called for a temporary statewide moratorium on new data center approvals until comprehensive environmental standards and public utility protections are enacted.

Community organizers and consumer advocates backed the Attorney General’s position, urging municipal zoning boards to prioritize local residential power affordability and water table conservation over unconstrained data center sprawl.
