The Iowa Reservation of the Iowa Tribe of Kansas and Nebraska straddles the borders of southeast Richardson County in southeastern Nebraska and Brown and Doniphan Counties in northeastern Kansas. Tribal headquarters are west of White Cloud, Kansas. The reservation was defined in a treaty from March 1861. Today the tribe operates Casino White Cloud on the reservation.
The Iowa, or Baxoje as they call themselves, Tribe originated in the Great Lakes region. They migrated south and west into Missouri, but were relocated to Kansas under the provisions of the Platte Purchase of 1836. Subsequent treaties in 1854 and 1861 further reduced the Iowa land holdings to the "Diminished Reserve." A band of Iowas left the reservation for Indian Territory beginning in 1878. They became the Iowa Tribe of Oklahoma. The bands that stayed became the Iowa Tribe of Kansas and Nebraska.
Today, the Iowa reservation consists of 12,000 acres (49 km2) that are almost evenly divided between the states of Kansas and Nebraska. The reservation includes parts of Brown counties in Kansas and Richardson County in Nebraska.
Located along the Missouri River, the reservation was once approximately 2,100-acre (8.5 km2) reservation includes 280 acres (1.1 km2) owned by the Tribe and 210.06 acres (0.8501 km2) in tribal member allotments. There were 947.63 acres (3.8349 km2) owned by the Tribe in Kansas, with an additional 181.01 acres (0.7325 km2) in tribal member allotments. In 1995 Bureau of Indian Affairs indicated that were 1,618.7 acres (6.551 km2) of Iowa tribal lands in trust status. Today the tribe reports the Iowa Tribe owns 2,707 acres (10.95 km2) within the reservation.
