About this map

Yankton dominates the northern bank of the Missouri River in this detailed 2017 study of the South Dakota and Nebraska border. The landscape is defined by the massive infrastructure of the Gavins Point Dam, which impounds Lewis and Clark Lake and created the smaller Lake Yankton immediately downstream. This area serves as a critical junction for regional history and modern conservation, featuring the Gavins Point National Fish Hatchery and the protected corridor of the Missouri National Recreation River.

Genealogists and local historians can trace rural settlements like Menominee, South Yankton, and Aten, alongside several significant burial sites including Benedictine Convent Cem, Aten Cem, and Beaver Creek Cem. The presence of Mt Marty College and the prominent Calumet Bluff further mark the transition from the developed city streets of Yankton to the rolling agricultural sections and drainage networks of Beaver Cr and Antelope Cr to the south.
