What it does
This bill ratifies a water-rights settlement agreement between the federal government, the Navajo Nation, the Hopi Tribe, and the San Juan Southern Paiute Tribe over Colorado River water allocations in northeastern Arizona. It authorizes the Secretary of the Interior to execute the settlement, allocates specific volumes of Colorado River water to each tribe, establishes trust funds for the tribes, funds a water-delivery pipeline (iiná bá–paa tuwaqat'si), and resolves long-standing competing claims to water resources in the region.
Why we flagged it
The bill's core function is to ratify and implement a negotiated settlement of competing tribal water claims under federal trust law. It is a settlement statute, not a regulatory or appropriations measure.
What the text implies
- The bill includes a 'limited waiver of sovereign immunity' (Section 18), which may allow tribes to be sued in federal court on settlement-related disputes—a trade-off for finality that could expose tribes to litigation they would otherwise avoid.
- The settlement appears to resolve claims 'finally' (Section 14 references waivers and releases), meaning tribes waive future claims to additional water rights, locking in current allocations even if hydrological or demographic conditions change.
