2020 Map of Garrison Dam North

About this map

Lake Sakakawea dominates this landscape where the Missouri River was transformed by the massive engineering of the mid-20th century. The intricate shoreline, defined by deep inlets like Garrison Bay and De Trobriand Bay, illustrates the complex topography created as the water rose against the high plains. On the southern banks, the planned layout of Pick City and the edge of Riverdale reflect the human history of the dam project, serving as hubs for workers and residents along the reservoir. Local residential development is evident in the street names of the Sakawea Estates Rd area, featuring roads like Apache Loop, Sioux Dr, and Arikara Ln. This survey captures the intersection of large-scale water management and the burgeoning recreational and residential footprint on the McLean and Mercer county line.
