2011 Map of Thebes

About this map

West Blacktail Creek and Big Porcupine Creek define the drainage patterns of this Rosebud County landscape, where ranching infrastructure stands out against the terrain. Water management is central to the area's utility, evidenced by several containment structures including the Thebes Lake Dam forming Thebes Lake, and the Montana Number 19 Dam located further south. Local land use is centered around sites like Erickson Ranch, which is served by a network of rural routes such as W Blacktail Rd and Big Porcupine Rd. The presence of the Erickson L and I Number 5 Dam and the geographical feature of Blind Coulee reflect the specialized agricultural and hydrological developments typical of the eastern Montana plains during the early twenty-first century.
