2020 Map of Circle Reservoir

About this map

Circle Reservoir serves as a central landmark in this Dawson County landscape, where the drainage patterns of the Missouri River basin are clearly defined by numerous creek systems. The map shows the convergence of Sullivan Cr as it flows toward the reservoir, alongside the winding paths of Alkali Cr and Pasture Cr. The terrain is marked by a network of rural routes and secondary roads, including Rd 412 and Rd P 8-S, which facilitate travel across these sprawling Montana sections. The detailed inclusion of Field Trl routes and the headwaters of the E Fork Pasture Cr and W Fork Pasture Cr illustrate the remote, water-dependent geography of the High Plains, providing a clear record of the local land use and infrastructure at this point in the twenty-first century.
