Why It Matters

The Senate Indian Affairs Committee in March will examine federal policies governing Indian water rights settlements, with specific focus on S. 953, the Northeastern Arizona Indian Water Rights Settlement Act — legislation that would resolve long-stalled water claims for the Navajo Nation, Hopi Tribe, and San Juan Southern Paiute Tribe.

The stakes are severe. Thirty percent of Navajo Nation families lack tap water, and nearly half of Native American households nationwide lack clean drinking water or basic sanitation. Meanwhile, 12 pending Indian water settlements collectively require approximately $12 billion in federal funding which is a number far exceeding available appropriations.

The hearing arrives amid a deepening Western water crisis. Lake Powell and Lake Mead sit at one-third capacity, and seven Western states missed their second consecutive federal deadline to propose post-2026 Colorado River management plans. Tribal nations have assumed historic leverage: tribes now control 22-26 percent of the Colorado River Basin’s water supply through senior rights under the 1908 Winters v. United States doctrine, giving them first claim before cities like Phoenix and Los Angeles.

A Legislative Push

Recent bipartisan action signals real momentum. Sen. Steve Daines (R-MT) secured Senate passage of Crow Tribe water rights legislation in December 2025, and two additional Daines-sponsored bills advanced from committee to the full Senate in summer 2025. Daines has consistently argued settlements save taxpayers money by avoiding costly litigation.

Sen. Ben Ray Luján (D-NM) secured $487 million in total funding for the Navajo-Gallup Water Supply Project through FY25 appropriations and Bipartisan Infrastructure Law allocations — a concrete example of settlements translating into infrastructure investment, though still a fraction of nationwide needs.

The Navajo Nation has retained Brownstein Hyatt Farber Schreck LLP, spending $790,000 over five quarters in 2024-2025 to advance S. 953 and related bills. The Pueblo of Laguna retained Jordan Law Firm LLC to push the Pueblos of Laguna and Acoma settlement — underscoring how tribes are investing heavily in congressional lobbying to break a long legislative logjam.

Infrastructure Deficits Remain Severe

Even where settlements exist, implementation lags. The Southern Ute Indian Tribe uses only one-quarter of its reserved water due to broken diversion structures and leaky canals dating back over a century. Water legally allocated to tribes has historically flowed downstream to cities and agricultural operations — a structural inequity the committee must confront.

The Bipartisan Infrastructure Law provided $2.5 billion through the Indian Water Rights Settlement Completion Fund, and the Reclamation Water Settlements Fund provides $120 million annually through FY2029 — well short of the $12 billion collectively required.

What Comes Next

Committee members will probe whether S. 953’s authorized funding is adequate, whether settlement timelines can accelerate, and how federal policy should adapt as tribal leverage grows. The outcome could accelerate — or stall — resolution of twelve pending settlements. With the Colorado River in crisis and interstate negotiations deadlocked, Indian water rights are no longer a peripheral issue. They’re central to the West’s water future.
