Sioux Valley Dakota Nation (SVDN), formerly called the Oak River Reserve, is located on the banks of the Assiniboine River in Southwestern Manitoba. The Oak River Reserve was created by an Order in Council of the Government of Canada in 1876. Sioux Valley Dakota Nation is the largest Dakota Nation in Canada with a membership of approximately 2500. SVDN is not a signatory to a Treaty.

SVDN is abundant in its culture, language and traditions. The ability to continue with the traditional values of the Oceti Sakowin will only bring good things for the community through the spirit of sharing and helping each other now and for generations to come.
