2014 Map of Wild Horse Reservoir

About this map

Wild Horse Reservoir anchors the southern portion of this landscape in Phillips County, reflecting the vital importance of water management in the northern Montana plains. The terrain is defined by a dense network of coulees that drain the surrounding high ground, including Tin Roof Coulee, Fourmile Coulee, and Threemile Coulee. These geographical features trace the natural path of runoff through the arid environment, where Wild Horse Cr and W Alkali Cr serve as primary watercourses. The presence of Us-191 provides a modern transportation link through this expanse of rangeland, following a corridor that has historically connected isolated ranching communities. The map highlights the intersection of several township and range boundaries, illustrating the systematic land division that governed settlement across the vast northern prairie.
