2020 Map of Needle Butte Reservoir

About this map

Round Butte Reservoir and Needle Butte Reservoir provide critical water storage in this high-plains landscape where the Garfield Co Rosebud Co line divides the terrain. The map reveals an intricate drainage system defined by the E Fork Little Porcupine Cr and its tributaries, which carve through a series of named rises including The Big Hill and Three Buttes. This network of coulees and hills dictates the path of local transit, such as Little Porcupine Cr Rd, which follows the contours of the drainage basin. The arrangement of land reflects a late-modern era of ranching and resource management, with prominent landmarks like Montgomery Hill and Jacques Coulee serving as essential reference points in a region where water management and elevation define the human footprint.
