Summary

What This Bill Does
This bill settles decades-long water rights disputes between the federal government, the State of Arizona, and three Native American tribes: the Navajo Nation, the Hopi Tribe, and the San Juan Southern Paiute Tribe. It allocates specific amounts of Colorado River water to each tribe, funds construction of a major water pipeline to deliver that water to tribal lands, and establishes trust funds totaling over $3.4 billion for water infrastructure, operations, and tribal development.

Who Benefits and How
- Navajo Nation: Receives 48,200 acre-feet per year of Colorado River water and approximately $2.88 billion in trust funds for water projects, renewable energy, and operations. Can lease water to other users in Arizona for up to 99 years.
- Hopi Tribe: Receives 2,300 acre-feet per year of Upper Basin water plus Cibola Water allocations, and approximately $515 million in trust funds for groundwater projects and development.
- San Juan Southern Paiute Tribe: Gains formal recognition of their 5,400-acre reservation and approximately $30 million in trust funds for water infrastructure.
- Construction and engineering contractors: Will benefit from $1.715 billion in pipeline construction contracts and additional tribal infrastructure projects.
- State of Arizona and existing water users: Gain certainty by settling tribal water claims, eliminating risk of future litigation.

Who Bears the Burden and How
- Federal taxpayers: Responsible for $5.136 billion in appropriations to fund the settlement.
- The three tribes: Must waive all past, present, and future water rights claims against Arizona and other parties in exchange for the settlement benefits.
- Bureau of Reclamation and Department of Interior: Must manage implementation, construct the pipeline, and administer trust funds.
