Oglala National Grassland dominates this portion of Sioux County, where a complex network of small-scale water management defines the high plains landscape. The drainage of Antelope Cr is captured by a series of impoundments including Jordan Reservoir and Lower Jordan Reservoir, illustrating the critical role of surface water storage for ranching and conservation in this semi-arid region. Further north, the landscape is punctuated by several other named reservoirs such as Henry Reservoir Number 1 and Merlin Mader Reservoir Number 1, often bearing the names of local ranching families.
