2014 Map of Johnson Dam

About this map

Beaver Cr and its tributaries carve a network of drainages across this Phillips County landscape, characterized by the distinct coulees that define the local topography. The namesake Johnson Dam sits at the center of the sheet, served by Johnson Rd and providing a focal point for water management in this cattle-ranching region. Further east, the terrain is marked by Guston Coulee, Moss Coulee, and the curiously named Pickhandle Coulee, which all flow toward the primary creek beds. The drainage patterns of Sevenmile Cr and Cottonwood Cr illustrate the arid-land hydrology where seasonal flows have shaped the earth over millennia. Local transportation is limited to established tracks like Harb Rd and the Ohs Cutacross Rd, highlighting the sparse settlement and expansive open-range nature of the Montana prairie in the early twenty-first century.
