South Dakota County

Lyman County, South Dakota

Big Bend Dam and the Missouri River's great oxbow - from Big Bend Dam and Lake Sharpe (the Missouri River at Lyman County makes one of the most dramatic geographic features in the Great Plains - the river curves nearly 30 miles in a great oxbow before returning within one mile of where it started, and Big Bend Dam's Lake Sharpe reservoir provides walleye fishing and recreation in the central South Dakota Missouri River country) to the Lower Brule Sioux Tribe's Lyman County reservation lands (the Kul Wicasa - the Lower Brule Sioux - maintain tribal lands along the Missouri River in Lyman County, their presence integral to the county's cultural landscape).
