2020 Map of Craig Reservoir

About this map

Larb Cr carves a winding path through this portion of Valley County, defining a landscape shaped by intermittent water and high plains drainage. The area is characterized by numerous coulees—deep, typically dry ravines—that feed into the larger creek system, including Hammond Coulee, Grant Coulee, and Black Coulee. In a region where water management is vital for ranching and land use, several man-made impoundments serve the local terrain, such as Korman Reservoir, McCuin Reservoir, and the namesake Craig Reservoir. Access to this remote stretch of Montana is provided primarily by Larb Creek Rd, which tracks alongside the northern reaches of the creek bed. The map reveals the intricate contours of the northern Missouri River breaks country, highlighting the isolation and topographical complexity of these drainages, including the southern flow of Ten Trees Cr.
