2020 Map of Johnson Reservoir

About this map

Johnson Reservoir serves as a central landmark in this portion of Dawson County, where the topography is defined by the branching drainage systems of Deer Creek. The landscape is carved by the N Fork Deer Cr, Middle Fork Deer Cr, and S Fork Deer Cr, illustrating the intricate hydrologic network of eastern Montana. In the northeast corner, the drainage of Lower Sevenmile Cr further shapes the terrain. A sparse network of county roads, including RD 435 and RD 448, provides the primary access through this rural ranching and agricultural region. The map reflects a modern survey of the public land system, detailing the section lines and township boundaries of T19N, T18N, and T17N across Ranges 52E and 53E.
