2014 Map of Circle Reservoir

About this map

Circle Reservoir serves as a focal point in this portion of Dawson County, where the high plains landscape is defined by a dendritic network of intermittent drainage. The area's hydrology is primarily shaped by Sullivan Cr and Alkali Cr, which carve through the terrain alongside the various branches of Pasture Cr. Transportation across this expansive ranching country is anchored by MT-200, which cuts diagonally across the northern townships, and Road 412 providing access to the eastern sections. This 2014 survey illustrates the persistence of the Public Land Survey System, showing the clearly defined township and range boundaries such as t21n r51e that continue to organize the agricultural and geographic identity of eastern Montana.
