2024 Map of Yellow Water Reservoir

About this map

War Horse National Wildlife Refuge anchors the southern portion of this landscape in Petroleum County, where conservation land meets the drainage patterns of the Central Montana plains. The terrain is defined by the winding course of McDonald Creek in the north and Elk Creek through the center, while Yellow Water Creek feeds into the reservoir area. These waterways historically dictated the movement and settlement of the region, providing rare water sources in a semi-arid environment. Infrastructure is sparse, primarily represented by Old Winnett Rd and Rte 244, reflecting the area's continued use for large-scale ranching and wildlife management. The map illustrates the intersection of public land boundaries and natural water features that have shaped local land use for generations.
