Caddo Indian Agency (Louisiana)
Indian Tribes Associated With This Agency
An agency was established in 1804 and was located at Natchitoches. About 1821, the agency was moved to Sulphur Fork in Arkansas Territory and at that time was called the Red River Agency. In 1825, it was moved about 25 miles down-stream to Caddo Prairie. That site was flooded and, as a result, in 1831 it was again moved about 50 miles even further down-stream to Peach Tree (or Orchard) Bluff, on the Bayou Pierre Channel, south of the site of Shreveport, Louisiana.
The agency was most commonly called the Red River Agency, although it was sometimes referred to as the Caddo Agency in Louisiana. The agency was discontinued in 1834 as the Caddo moved to Texas. In 1859, the Caddo Indians moved to the Wichita Agency in Indian Territory. The Quapaw, who once were under the Caddo Agency in Louisiana, eventually moved to their reservation in Indian Territory and were placed under the Neosho Agency.

Letters received by the Office of Indian Affairs from the Blackfeet Agency, 1824-1842, have been microfilmed by the National Archives as part of their Microcopy Number M234, Roll 31. Copies are available at the National Archives and at the Family History Library and its family history centers (their microfilm roll number 1660761). The Office of Indian Affairs filed some correspondence under the heading of "Caddo" even after the agency was closed, mainly dealing with the payment of annuities to the Caddo Indians.
