2020 Map of Garrison Dam South

About this map

Riverdale sits at the northern edge of this Missouri River landscape, positioned just below the engineering works of Lake Sakakawea. The terrain is defined by the sharp transition from the river valley to the surrounding plateaus, where local drainages like Elm Cr and Raymond Cr cut through the topography. In the southern portion of the quadrangle, the Knife River Indian Villages National Historic Site preserves a significant cultural landscape on the western bank of the Missouri River, marking a site of long-standing human habitation and commerce. Near the dam, the infrastructure of the Garrison Dam National Fish Hatchery and the Garrison Dam Recreational Airpark highlight the area's development for conservation and utility. Rural landmarks such as Saint Pauls Cem indicate the established agricultural communities that line the grid of local roads like Co Rd 28 and 44th Ave NW.
