Aboriginal Title Lands Map

This map identifies the aboriginal title lands as identified from the 1960 and 1966 US District Court for Oregon.   This boundary explicitly describes but does not restrict the exclusive rights of Tribal members for hunting, fishing and gathering within this boundary.  ( CTUIR v. Maison II & CTUIR v. Maison III)

Licensed Upland Hunting Areas

CTUIR hunting licenses are required for hunting on Tribal fee and trust lands and individual Indian allotments within the reservation.  Property boundaries may not be marked and it is the responsibility of the hunter to be aware of the properties they are hunting on.  It is the hunters responsibility to obtain land owner permission to access or cross properties for the purpose of hunting.  Purchase of the license grants permission to hunt upland birds and waterfowl on Tribally owned lands but does not secure access to travel across private individual land or allotments.

Treaty Boundary Map

This map identifies the treaty area as compared to the diminished land area of the Confederated Tribes of the Umatilla Indian Reservation.   In 1871, the Reservation boundary was surveyed for the federal government.  Although the Treaty of 1855 described an area of 500,000 acres, this boundary contains only approximately 245,000 acres.  The Umatilla Allotment Act (Slater Act) of 1885 authorized the allotment and diminishment of the reservation to 120,000 acres.  In 1939 , a Congressional act authorizes the Secretary of Interior to restore the Umatilla Indian Reservation 14,000 acres of Federal lands located south of the diminished boundary.
