Indian Peaks Band Files to Protect Tribal Water Rights
On April 1, 2026, the Indian Peaks Band of the Paiute Indian Tribe of Utah filed a Notice of Appeal and Petition for Stay with the Interior Board of Land Appeals (IBLA), challenging the Bureau of Land Management’s March 2, 2026, approval of the Pine Valley Water Supply Project.

The filing seeks review of BLM’s decision authorizing a large‑scale groundwater extraction and pipeline project in southern Utah and asks the IBLA to stay the project approvals while the appeal is pending. The Band argues that the decision violates federal law, including the National Environmental Policy Act, and unlawfully threatens the Band’s federally reserved water rights and culturally significant resources.

Winnemucca Indian Colony v. United States Cert Petition
Here:
Questions presented:
(1) Is the United States’ promise to provide the Winnemucca Indian Colony, a federally recognized Tribe with lands held in trust established by an Executive Order and a separate legislative act, coupled with the government’s nearly exclusive statutory and regulatory control over the water on Indian lands, sufficient to entitle an Indian tribe to money damages when the United States breaches its fiduciary duty to protect the natural resources on those Indian lands?
(2) Did the Federal Court of Appeals, Federal Circuit, err when it affirmed dismissal of the Winnemucca Indian Colony’s third claim for relief – Breach of Trust – Water?
(3) Can the Winnemucca Indian Colony state a cognizable claim for breach of trust against the United States in relation to BIA failure to prevent trespass and theft of natural resources by third parties, under the Winters doctrine and 25 C.F.R. § 152.22?
