2020 Map of McClure Reservoir

About this map

McClure Butte and Eagle Butte rise above the complex drainage networks of eastern Montana, where the boundary between Prairie and Custer counties cuts across a rugged, dissected landscape. This arid region relies on carefully managed water sources, evidenced by Silvertip Reservoir in the north and Hunter Cr Reservoir to the south. The terrain is defined by the winding paths of Crooked Cr and its tributaries, including the N Fork Crooked Cr and the descriptively named Lost Boy Cr. Historically significant water points like Johnson Spring and Bootlegger Spring appear tucked into the coulees, marking essential resources for ranching and transit in this sparsely populated portion of the Great Plains. The map's detail reveals the intricate topography of the badlands-style erosion typical of the Yellowstone River watershed.
