The Klamath Tribes consist of three groups of people: the Klamath, Modoc, and Yahooskin Band of Snake Indians. These groups inhabited about 22,000,000 acres in northern California and southern Oregon. The Klamath and Modoc developed an inland marsh culture dependent on water, with much of their material culture relying on tule and cattail plants for baskets, housing, clothing, utensils, and toys. The Yahooskin Band of Snake Indians, a division of the Paiute Tribes, were a gathering culture and lived mostly on the high desert of the land base. All three groups depended on the land's resources, including roots, berries, herbs, game animals, waterfowl, upland game birds, and fish such as mullet, trout, and salmon. In 1864, a treaty with the United States established the Klamath Indian Reservation; its outer lines reflected the peak-to-peak boundaries negotiated by tribal leaders, while inner lines showed the boundaries Congress finally approved in 1870. From 1864 to 1954, the tribes developed a self-sufficient government that provided services including health, education, employment, and housing, while tribal members received shares of profits from timber sales and other ventures such as grazing fees, contributing heavily to the economy of Klamath County. In 1953, the U.S. Congress adopted the policy of termination of federal services over Indian tribes, and the Klamath Termination Act was signed in 1954 without the tribe's approval. The land became the Winema National Forest, tribal members received shares of the sale proceeds, and after 1954 the U.S. no longer considered the people of the Klamath Tribes to be Indians, seeking to mainstream them into society. With federal recognition ended and the land base liquidated, many services ended, including rights to hunt and fish according to the State of Oregon. In the early 1970s, tribal members brought a federal court case, Kimbol v. Callahan, and in 1974 it was settled in favor of the Klamath Tribes, affirming rights to hunt and fish on former reservation lands. The tribe then reorganized its government, implemented biological programs to study fish and game, and established tribal hunting and fishing rules. Restoring federal recognition became the next step in regaining what termination had ended, and that recognition was restored on August 27, 1986. Since 1986, the tribe has implemented service programs in health, education, employment, and housing, while maintaining rights to hunt, fish, and gather on former reservation lands. In 1997, the Klamath Tribes opened the Kla-Mo-Ya Casino, and in 2001 opened a new administrative building. Their outlook for the future is to assist tribal members with services, economic development, and the return of the land.
