2017 Map of Brown Coulee

About this map

Brown Coulee dominates this portion of Rosebud County, where the high plains of eastern Montana are etched by a series of drainage features and water management structures. The landscape is defined by the catchments of Brown Coulee Reservoir and Blacktail Reservoir, which support ranching and local water needs in this arid environment. Significant topographic features like Badland Coulee and Hallanger Coulee intersect the terrain, illustrating the erosional patterns of the region. Transportation is limited to a sparse network of ranch routes including Kerns Rd, which provides access to more remote areas such as Lower Blacktail Reservoir and Kerns Reservoir. The drainage system of E Blacktail Cr ties these reservoirs together, reflecting a reliance on seasonal runoff to sustain the local geography.
