United States v. Powers

Background

In this case the United States sued owners of allotted land on the Crow Reservation who had long taken water from Lodge Grass Creek and the Little Big Horn River to irrigate farms. The landowners hold fee simple title to tracts allotted under an 1868 treaty and later federal statutes, and they and their predecessors have long carried water by private ditches because no other source is available. The Government asked the courts to stop those diversions, arguing earlier federal irrigation projects and Interior Department authority reserved the streams’ water for other uses.

Reasoning

The Court considered whether people who received allotted land and later patents could rely on reservation waters needed to farm. It explained the 1868 Treaty contemplated individual homes and farming and that water was essential to make those allotments productive. Later laws and the Secretary’s authority did not show a clear intent to deny allottees participation in water use, and the patents conveyed land “with all rights and appurtenances,” which supports the landowners’ practical water use. The Court therefore found no ground to award the United States the permanent injunction it sought and affirmed the lower courts’ dismissal.

Real world impact

The decision protects individual Crow landowners’ ability to use nearby stream water to irrigate their farms and blocks the Government’s requested ban on those diversions. The Court expressly declined to measure the exact scope or priorities of each water right, so detailed allocation, shortages in drought years, or priority disputes may still require further proceedings or clarification.
