2015 Map of Somerville Flats East

About this map

Somerville Flats and the high ridges of Kinney Divide define this landscape in the eastern Powder River Basin. The terrain is characterized by a dense network of seasonal drainage patterns, with named draws like Windmill Draw, McLaughlin Draw, and Laskie Draw carving through the hills. This 2015 U.S. Geological Survey representation captures the boundary between Johnson and Campbell counties, showing a region where water management is critical, as evidenced by the presence of Lula Reservoir. The area is sparsely settled, with Kinney Divide Rd providing the primary transit through the elevated terrain. Local watercourses such as Barber Cr and Williams Draw further illustrate the complex topography that has shaped land use and ranching in this portion of Wyoming.
