2015 Map of Black Draw

About this map

The Powder River carves a winding path through the borderlands of Wyoming and Montana, defining a landscape of high plains and deep drainage channels. This 2015 survey reveals the intricate network of watercourses and topographical basins that shape Campbell County, including Watson Basin and a series of named ravines like Black Draw and Water-Gap Draw. Small-scale ranching and water management are evident through features like Warren Reservoir and Greenough Reservoir, which anchor the sparse drainage of Williams Cr and LX Bar Cr. The map captures the remote character of the Powder River Basin just south of the state line, where infrastructure is limited to routes such as Fence Creek Rd and SA Rd. It serves as a precise record of the regional hydrology, from the northern Line Cr to the southern reaches of Coal Cr and Crooked Cr.
