2020 Map of Niles Coulee

About this map

Niles Coulee and the surrounding drainage basins of Valley County, Montana, define this high plains landscape. The terrain is deeply etched by a network of seasonal watercourses, including North Frenchman Coulee, Frenchman Coulee, and Little Frenchman Coulee. In an environment where water management is critical for ranching and land use, numerous small catchments are distributed across the township lines of T25N and T26N. These include the Corral Reservoir, Mc Kee Reservoir, and High Moon Reservoir. Local infrastructure consists primarily of isolated access routes such as Triple Cross Access Rd and Stone House Rd, reflecting a sparse settlement pattern focused on livestock and resource management. The presence of Niles Spring and drainage from Ten Trees Cr highlights the subtle but vital riparian features that have historically dictated the placement of homesteads and corrals in this part of the Missouri River basin.
