Upper Sioux Agency

Upper Sioux Agency (or Yellow Medicine Agency), was a federal administrative center established in response to treaties with the Dakota people in what became Yellow Medicine County, Minnesota, United States.[2] Located on the Minnesota River south of Granite Falls, Minnesota, the government-run campus of employee housing, warehouses and a manual labor school was destroyed in the Dakota War of 1862.[3] The grave of Chief Walking Iron Mazomani, a leader of the Wahpetonwan (Dwellers in the Leaves) Dakota tribes, who was killed during the 1862 Dakota War's Battle of Wood Lake, is here.[2] The site was listed on the National Register of Historic Places in 1970 for having state-level significance under the themes of archaeology, architecture, education, and social history.[4]

Established as a Minnesota state park in the 60s, the park is being closed and transferred to the tribal members of the Upper Sioux Community.[3] State Route 67, that traverses through the park, was closed after failing deep underground. The highway would require expensive repairs along with the bridge over the Yellow Medicine River that has been compressed by the movement so much that it needs to be removed or replaced.[5] State funds will be used to buy land for replacement recreational opportunities and pay for road and bridge demolition.[6]
