About this map

The high plains of Valley County are defined by a complex network of seasonal drainages and small-scale water management. This landscape, as it appeared in the mid-1980s, is shaped by significant coulees and the headwaters of several creeks. Ruby Reservoir stands out as a primary water source in this semi-arid region, supporting the local ranching economy. The drainage patterns are dominated by the Ash Coulee and Bob Coulee systems, which channel runoff through the breaks. Further south, the terrain opens into the valleys of North Fork Antelope Creek and South Fork Antelope Creek, while Hardscrabble Creek cuts across the eastern portion of the quadrangle. The lack of concentrated settlements highlights the area's use for grazing and the importance of every named water feature for navigating and managing the range.
