Winters v. United States, 207 U.S. 564 (1908), was a United States Supreme Court case clarifying water rights of American Indian reservations. This doctrine was meant to clearly define the water rights of indigenous people in cases where the rights were not clear. The case was first argued on October 24, 1907, and a decision was reached January 6, 1908. This case set the standards for the United States government to acknowledge the vitality of indigenous water rights, and how rights to the water relate to the continuing survival and self-sufficiency of indigenous people.
