A historic agreement aimed at securing long-overdue Colorado River water rights for three Tribal Nations in northern Arizona has stalled after opposition from four Upper Basin states—Colorado, New Mexico, Utah, and Wyoming. The proposed settlement involves the Navajo Nation, the Hopi Tribe, and the San Juan Southern Paiute Tribe and would resolve the largest remaining unresolved tribal water claim in the Colorado River Basin.
The settlement would authorize approximately $5 billion in federal funding for water infrastructure projects, including pipelines, treatment systems, and delivery networks designed to bring reliable drinking water to communities where many residents still lack running water. It would also establish a reservation for the San Juan Southern Paiute Tribe, which remains one of the few federally recognized tribes without a reservation homeland.
According to reporting by ProPublica and KJZZ, the opposition from the four Upper Basin states is tied to broader disputes over how Colorado River water will be allocated after current operating agreements expire in 2026. State officials have raised concerns about provisions that could allow tribes to lease portions of their water rights, potentially affecting future river management negotiations.
Water Access Remains a Critical Need.
The settlement is particularly significant because many Navajo and Hopi families still live without dependable access to clean drinking water. Previous reports indicate that nearly one-third of homes on the Navajo Nation lack running water, forcing some families to travel long distances to haul water for daily use. Similar challenges exist within Hopi communities.
Hopi Tribal Council Member Marily Tewa emphasized the importance of the agreement for future generations, telling ProPublica:
“I’m speaking on behalf of my children, my grandchildren and their children that haven’t come yet. I hope, in the future, that they will have water.”
Decades in the Making.
The proposed settlement is the result of years of negotiations among the tribes, Arizona, federal agencies, and local stakeholders. It would settle claims involving the Colorado River, the Little Colorado River, and regional groundwater supplies. Tribal leaders have described the agreement as one of the most significant water settlements ever negotiated in the United States.
The agreement also reflects a broader effort to address historical inequities. Native Nations were largely excluded from the original 1922 Colorado River Compact, which divided river water among seven states but failed to fully recognize tribal water rights. Many tribal claims remain unresolved more than a century later.
Environmental and Cultural Importance.
For the Hopi Tribe, water security extends beyond household use. The tribe is a partner in First Nations Development Institute’s Stewarding Native Lands Advancing Tribal Nature-Based Solutions initiative. Through that program, Hopi communities are restoring riparian areas in the Pasture Canyon watershed to improve habitat for aquatic and terrestrial species, protect culturally significant lands and waters, and increase water retention during prolonged drought conditions.
What Happens Next?
Without a settlement, the tribes may face years—or even decades—of continued litigation and adjudication over water rights. Water experts warn that unresolved claims add uncertainty to already difficult negotiations over the future of the Colorado River, which is under increasing pressure from drought, climate change, and growing demand across the Southwest.
The dispute comes as federal, tribal, and state leaders work toward a new framework for managing the Colorado River after current operating rules expire in 2026. The outcome could determine not only the future of tribal water access but also the broader balance of water use across the American West.
