The Gila River Indian Community is the first Arizona water rights holder to publicly pursue the federal government’s new offer of compensation to leave Colorado River water in Lake Mead.

Tribal Gov. Stephen Roe Lewis announced the plan on Monday at a gathering of Sen. Kyrsten Sinema’s water advisory council, which is reviewing ways to spend $4 billion of Inflation Reduction Act funds targeted at Colorado River drought relief, as well as funds approved in an infrastructure funding law.
