2018 Map of Riverdale North
USGS Topo · Published 2018About this map
Lake Sakakawea dominates this 2018 survey, its expansive waters shaping the geography of Mercer and McLean Counties near the Garrison Dam vicinity. The settlement of Riverdale occupies the southwestern corner, characterized by residential street patterns such as Missouri Dr and 7th St NW perched above the drainage of Angie Brown Coulee. North of the town, the massive peninsula of Mallard Island extends into the lake, while to the northeast, the waters of Audubon Lake are visible along the corridor of State Highway 83. The map details the modern landscape of this Missouri River reservoir area, illustrating the transition from open prairie to managed waterways and agricultural section lines like Co Rd 15 and 14th St NW.
