2011 Map of Cochran Reservoir

About this map

Cochran Reservoir anchors this landscape in eastern Montana, serving as a primary water source in a region defined by complex drainage systems and ranching infrastructure. The map reveals a high concentration of water management features, including several grazing and diversion dams that illustrate the area's agricultural history. Named landmarks such as the Cockran Grazing Number 2 Dam and Pilister Diversion Dam indicate a history of land use focused on livestock and irrigation. The terrain is deeply etched by various branches of Willow Creek, including its North, Middle, and South forks. Distinctive geological features like Nelson Draw, Nelson Washout, and Torgerson Draw provide insight into the natural erosion patterns of this prairie environment, while local routes like Ridge Rd and Lobban Rd trace the paths through the upland areas.
