2017 Map of Circle Reservoir

About this map

Circle Reservoir lies at the heart of this Dawson County landscape, serving as a vital catchment in an area defined by its seasonal drainage systems. The terrain is intricately carved by intermittent waterways like Alkali Cr and Sullivan Cr, which flow through the rolling breaks of eastern Montana. This survey illustrates the modern rural infrastructure of the region, where gravel routes such as Rd N 115 and Rd M 13-S follow section lines to connect isolated ranch lands. The drainage pattern of Pasture Cr and its tributaries, including the E Fork Pasture Cr and N Fork Pasture Cr, shows the natural erosion typical of the Missouri Plateau. A few primitive routes, labeled as Field Trl, provide the only access into the more deeply dissected coulees and ridges away from the primary county roads.
