Waltman sits as a central point of reference in this arid expanse of Natrona County, where the landscape is defined more by its drainages and seasonal water sources than by human density. The hydrology of the region is traced through the S Fork Powder River and several distinct draws, including Powder River Draw and Sand Draw, which channel the limited moisture of the Wyoming basin. Local land use is centered around water management for ranching or local needs, evidenced by the Rochelle Reservoir and Cooper Reservoir.
