2017 Map of Garrison Dam North

About this map

Lake Sakakawea dominates the landscape of this region on the border of McLean and Mercer counties, where the massive engineering of the Garrison Dam transformed the Missouri River valley into a sprawling reservoir system. The settlement of Pick City sits just west of the dam, serving as a gateway to the water and the recreation-focused developments such as Sakakawea Estates Rd. The terrain is characterized by the complex shorelines of Garrison Bay and De Trobriand Bay, where deep inlets cut into the surrounding plains. For those exploring the landscape on foot, the North Country National Scenic Trail winds along the southern bluffs near the dam. The street names in the residential areas, including Apache Loop, Sioux Dr, and Arikara Ln, reflect the cultural heritage and indigenous history of the Missouri River basin before the inundation of the valley.
