The Lake Traverse Reservation is located in the Northeastern part of South Dakota and a small portion of southeastern corner of North Dakota. The reservation boundaries extend across seven counties, two in North Dakota and five in South Dakota. We have a total of 13,872 tribal members located throughout the United States and others serving overseas in the Armed Forces which is one of the many reasons we have created this website, to help keep our tribal members living either on or off of the reservation in touch with their tribe.
