The Sisseton Wahpeton Tribe has lived for generations in the Glacial Lakes country. (Sisseton translates to People of the Marsh.) The tribal headquarters and college at Agency Village — 7 miles south of Sisseton —features a main building shaped like four drummers. Visitors are welcome to explore nature on trails behind the college. Agency Village is also home to the Sisseton Wahpeton pow wow, the oldest in South Dakota and second oldest in the USA. The smaller Flandreau Santee Sioux Tribe, like the Sisseton Wahpeton, has roots in the Dakota people who were uprooted from Minnesota after broken treaties led to an 1862 uprising. The Santees’ headquarters is in the historic town of Flandreau.
