Lake Traverse Indian Reservation
The Lake Traverse Indian Reservation is the homeland of the Sisseton Wahpeton Oyate, a branch of the Santee Dakota group of Native Americans. The reservation is located in parts of five counties in extreme northeastern South Dakota and parts of two counties in southeastern North Dakota, USA. Over 60 percent of its land area lies in Roberts County, South Dakota, but there are lesser amounts in Marshall, Day, Grant, and Codington counties in South Dakota, as well as Sargent and Richland counties in North Dakota. Its resident population of 10,408 persons was counted during the 2000 census. About one-third of its inhabitants claim to be of solely Native American heritage. Its largest community is the city of Sisseton, South Dakota.

- Darlene Renville Pipeboy is an enrolled member of the Sisseton-Wahpeton Oyate. Her grandfather, Joseph Renville, was among those who befriended French mapmaker, Joseph Nicollet. Today, Pipeboy volunteers at the Nicollet Tower near Sisseton. "Being a Dakota, a twin and a woman is my identity," Pipeboy says. "Those three things are important today and traditionally."
- Paul War Cloud, (1930–1973) a Sisseton-Wahpeton, was born in 1930 near Sica Hollow. A self-taught artist, War Cloud realistically depicted Dakota culture and tradition in his paintings. Many of his works are on display at the Tekakwitha Fine Arts Center in Sisseton. A War Cloud mural, "Unity Through the Great Spirit," hangs at the Cultural Heritage Center in Pierre. War Cloud died in 1973.
- Gabriel Renville (1824–1892) was the last chief of the Sissetowan and Wahpetowan (non-hereditary). Born in Chief Sweet Corn's village on Lake Traverse, he was born into the Rainville/Renville clan—a family of French and Dakota origins operating a trading post in Minnesota. His appointment as chief in 1866 was seconded by the Sisseton-Wahpeton in 1867.
