2020 Map of Big Coulee Dam

About this map

Bisbee sits at the southwestern edge of this Towner County landscape, a region defined by its numerous prairie potholes and intermittent waterways. The topography is dominated by the drainage systems of Mauvais Coulee and the area surrounding Big Coulee Dam. This 2020 survey illustrates the rigid, sectioned grid of North Dakota's agricultural heartland, where routes like Higgins Rd and Dam Rd provide access through the glaciated terrain. The map details the small settlement of Big Coulee and the water management infrastructure critical to this rural environment. Genealogists and local historians can trace the property divisions across multiple townships, including T160N R67W and T159N R68W, while observing the contemporary road network that connects these remote prairie communities.
