A bill to amend the Grand Ronde Reservation Act, and for other purposes.

S 910 amends the Grand Ronde Reservation Act to specifically define the reservation's boundaries as the 84-acre Thompson Strip in Oregon. It directly affects the Confederated Tribes of Grand Ronde by prohibiting the use of any land acquired through federal land claim settlements (including property bought with settlement funds) for class II or III casino-style gambling under federal law. The bill adds a new provision stating such land cannot be used for gaming, while explicitly stating it does not change existing treaty rights of federally recognized tribes. This is a concrete policy change limiting gaming eligibility on specific tribal lands obtained via settlement agreements. The bill focuses on clarifying land boundaries and restricting gaming operations, not on broader tribal policy.
