Prairie Island Indian Community is a Mdewakanton Sioux Indian reservation in Goodhue County, Minnesota, along the Mississippi River, in and around the city of Red Wing. It was created in 1889, with boundaries modified after that time. Much of the reservation land was lost following construction of Lock and Dam No. 3 along the river by the United States Army Corps of Engineers to improve navigation. Later, the Prairie Island Nuclear Power Plant was built nearby. The community has grabbed headlines because of the decision to store radioactive waste in above-ground steel casks.
