2014 Map of Tongue River Dam

About this map

The Tongue River Reservoir dominates the southeastern portion of this landscape, created by the Tongue River Dam which impounds the waters of the Tongue River. This 2014 survey documents a rugged corner of Montana where Rosebud and Big Horn counties meet. The terrain is defined by a dense network of seasonal drainages and springs that feed into the river system, including Fourmile Cr, Post Cr, and Leaf Rock Cr. Local navigation relies on a few primary routes such as Birney Rd and MT-314, which traverse the high ground between features like Barber Draw. The mapping of numerous specific springs, such as 07S40E16BDAA01 Spring, provides essential detail for understanding water access in this semi-arid environment, while the forks of N Fork Monument Cr and S Fork Monument Cr trace the intricate topography of the uplands.
