Southwest Tribes Stand Firm on Colorado River Water Rights Amid Proposed Federal Reductions

PHOENIX, Arizona — Indigenous leaders in the United States Southwest are asserting their legal and sovereign water rights following a Department of the Interior announcement on Friday regarding future water delivery cuts from the Colorado River. The Gila River Indian Community and the Colorado River Indian Tribes (CRIT) have signaled their commitment to protecting their allocations as the federal government moves to address a 26-year drought that has reached a critical stage in 2026. Attorney General Rebecca Loudbear of the Colorado River Indian Tribes highlighted the significance of the tribes' position, noting that CRIT holds rights to over 23 percent of Arizona’s total Colorado River allocation. In a communication to the Bureau of Reclamation, Loudbear stated that the limited role offered to tribes in the decision-making process did not reflect the legal extent of their water rights. The CRIT is recognized as one of the largest and most legally secure shareholders of water in the state of Arizona. Gila River Indian Community Governor Stephen Roe Lewis also expressed a firm stance, indicating that the community is prepared to use all available forums to protect its interests. The Gila River Indian Community currently receives water via the Central Arizona Project, which is subject to junior priority rights. Governor Lewis described the federal operating guidelines as a deviation from the "law of the river" and called for the government to better uphold its trust responsibilities to the 30 tribes reliant on the basin. The Colorado River currently supports more than 40 million people and 5.5 million acres of farmland. Despite the challenges posed by record-low snowpack and historically low levels at Lake Mead, tribal leaders continue to lead advocacy efforts to ensure Indigenous water security and long-term sustainability for their communities.
