Note:
Much of the land (over 160,000 acres) of the Cheyenne River Indian Reservation and the Standing Rock Reservation was destroyed in the construction of this dam. Over and above the acreage loss, most of the reservations' prime agriculture land was included in the loss. The loss of this land had a dramatic effect on the Indians who lived on the reservations.
