1970 Map of Mandaree SW

USGS Topo · Published 1978

About this map

Lake Sakakawea dominates the landscape of Dunn County, North Dakota, following a 1970 field check of the Missouri River Basin’s development. The map details the complex shoreline of this reservoir where it meets the Little Missouri River, noting a specific pool elevation of 1838 feet. Much of the northern and western terrain is defined by the Fort Berthold Indian Reservation Boundary, illustrating the intersection of tribal lands with the altered hydrology of the river valley. Numerous drainages such as Moccasin Creek and Jim Creek feed into the reservoir, carving through the upland topography of the Mandaree SW quadrangle. Areas marked by a light-blue dashed pattern indicate zones subject to controlled inundation, a critical detail for understanding the managed water levels of the era.
