Wind River Indian Reservation is an Indian reservation shared by the Eastern Shoshone and
Northern Arapaho tribes of Native Americans in the central western portion of the U.S. state of
Wyoming. It is the seventh-largest Indian reservation in the United States, encompassing a land area
of 8,995.733 (mi), encompassing most of Fremont County
The reservation is surrounded by the Wind River Mountain Range, Owl Creek
Mountains, and the Absaroka Mountains. The 2000 census reported a population of 23,250
inhabitants. The largest town is Riverton. Headquarters are at Fort Washakie. Also home to the
Wind River Casino, Little Wind Casino (Both Northern Arapahoe) and Shoshone Rose Casino (Eastern Shoshone), which are the only casinos in Wyoming.
The Wind River Indian Reservation was established for the Eastern Shoshone Indians in 1868. Camp
Auger, a military post with troops was established at the present site of Lander on June
28, 1869. In 1870 the name was changed to Camp Brown and in 1871 the post was moved to the current site of Fort Washakie .
The nickname was changed to honor the Shoshone Chief Washakie in 1878 and continued to serve as
a military post until its abandonment in 1909.A government school and hospital
functioned for many years east of Fort Washakie and children were sent here to board during the
school year. St. Michael's at Ethete was constructed in 1917-20. The village of Arapahoe was
originally established as a sub-agency to distribute rations to the Arapaho and at one time had a large
trading post.
In 1906 a portion of the reservation was ceded to white settlement and Riverton evolved on some of
this land. Lands were allotted in the 1800's to the various families and names were anglicized.
Irrigation was brought in to develop farming and ranching and a flour mill constructed near Fort Washakie.
