2020 Map of Yellow Water Reservoir

About this map

Yellow Water Reservoir serves as the central focal point in this sparsely populated section of Petroleum County, Montana. The landscape is defined by the drainage patterns of Yellow Water Cr and Elk Cr, which carve through the high plains terrain. Significant for local transit and historical routing, Old Winnett Rd traverses the northern section of the quadrangle, while Rte 244 provides a modern north-south connection in the southeast. These routes reflect the area's ongoing reliance on gravel and paved corridors to bridge vast distances between ranching hubs. In the far northern reaches, McDonald Cr meanders through the drainages, illustrating the vital role these seasonal and permanent water sources play in the regional ecology.
