Klamath Indian Agency (California)
Indian Tribes Associated With This Agency
The Klamath Agency was established in 1856 and was responsible for the Indians of northern California, particularly those near the mouth of the Klamath River. This agency also had some responsibility for the Hoopa Valley and Smith River Indians, as well as some of the other Indians of northern California. The Indians served by the Klamath Agency were assigned to the Northern District when the agencies were discontinued in 1860. Most of the Klamath Indians served by this agency were leter associated with the Hoopa Valley Agency.
The Klamath Agency in Oregon is an entirely different agency and should not be confused with the one in California.
