The fourth largest reservoir by volume in the United States, Lake Oahe, is the product of the Oahe Dam on the Missouri River.

Native American culture runs deep in these parts: the western part of the lake is split into the Cheyenne River Indian Reservation and the Standing Rock Indian Reservation. The legendary Sioux leader, Sitting Bull, may be buried at two possible sites near the lake.

In the 1960s, the US Army Corps of Engineers initiated 5 dams that flooded 200,000 acres of the habitable land in this area. As of 2015, the poverty rate is still associated with the history of this event.

In 2016, the Dakota Access Pipeline (DAPL) made repeated attempts to cross Lake Oahe to bring crude oil from the Bakken oil fields in the northwestern corner of North Dakota to the oil refinery at Pakota, Illinois.

Many Bothans died to bring you this information.
