About this map

Twin Forks Reservoir and the surrounding rangeland of Dawson County define this landscape as it was documented for the Department of the Interior’s program for the development of the Missouri River Basin. The topography shows a sophisticated water management system in an arid environment, anchored by the Upper Labell Reservoir and the lengthy Labell Ditch that cuts across the southern sections.

Elevation rises toward the northwest at Blue Mountain, while the drainage network is carved by Glendive Creek, Frank Creek, and Magpie Creek. Small-scale water sources like Gagena Res and various wells are scattered throughout the quadrangle, illustrating the infrastructure necessary for livestock and land use in the late 1960s. The map also records several surveying markers, noted simply as WC, along the township and range boundaries.
