2017 Map of Needle Butte Reservoir

About this map

Round Butte Reservoir and the adjacent Needle Butte Reservoir provide critical water storage in this section of the High Plains where Rosebud and Garfield counties meet. The landscape is defined by its drainage systems and prominent elevations, such as The Big Hill and the distinctive Round Butte. These features are connected by a network of seasonal watercourses including Jacques Coulee and Caladine Coulee, which carve through the terrain toward the south. The distribution of remote access routes like Little Porcupine Cr Rd and Garfield Co Road 216 indicates the expansive, ranch-focused land use of the region. This 2017 survey details the complex system of coulees and buttes, including Three Buttes, that shaped local navigation and land management between the forks of E Fork Little Porcupine Cr and Cottonwood Cr.
