About this map

Vandalia serves as the focal point of this 1960s study, situated where the Burlington Northern railroad tracks parallel the winding course of the Milk River. The landscape is defined by the sophisticated water management infrastructure of the Missouri River Basin development program, most notably the Vandalia Dam and the extensive South Canal. These features highlight the era's focus on agricultural irrigation and flood control in Valley County.

Away from the river valley, the terrain transitions into a complex network of dry washes and eroded breaks. Named features like Ash Coulee, Buffalo Coulee, and Hardscrabble Creek illustrate the intricate drainage patterns of the high plains. The map also records localized engineering details such as the Spillway and Riser 2163, providing a clear view of the regional topography before further modern development.
