Klamath Agency was an Indian agency for the Klamath Indian Reservation established May 12, 1866, on the shore of Agency Lake.[3] The current site of the former agency is 3 miles (5 km) north of that location.[3] The Klamath Reservation was terminated in 1961, but the community at Klamath Agency still exists.[3] Klamath Agency post office was established in 1878 and ran until 1965, when the mail was instead routed to Chiloquin.[3]
In 1870, there was a sawmill at the agency; it burned down in 1911.[4] In the 1890s, Klamath Agency was the site of two Indian boarding schools—one for boys and one for girls.[5]
In 1945, Ray Enouf Field was dedicated at the agency. The airfield was named in honor of the only Klamath Indian to die in World War II.[6] Raymond L. Enouf was a Marine private first class, who was killed while acting as a medic in the front lines during the Battle of Iwo Jima.[6]
The Klamath Agency is now home of the Sage Community Charter School.
