2015 Map of Bowman Flat

About this map

The Powder River meanders sharply through this portion of Johnson County, defining the local geography with its complex oxbows and deep silt-cut bends. This high plains landscape is characterized by its drainage patterns, where seasonal flows have carved features like Red Draw, Hynes Draw, and Hupp Draw into the surrounding flats. The reliance on water management in this arid ranching country is evident through the naming of localized catchments such as Culp Number 1 Reservoir and the Iberlin Fourmile Cr Number 2 Reservoir. Named topographic benches, including Bowman Flat and Ricketts Flat, provide relatively level ground above the river's winding path. Tributaries like Beaver Cr and Pumpkin Cr converge with the primary river valley, illustrating the critical role of these watercourses in an otherwise dry, expansive terrain.
