2014 Map of Johnson Reservoir

About this map

Johnson Reservoir and the complex drainage of the Deer Creek system define this landscape in Dawson County. The map details the convergence of N Fork Deer Cr, Middle Fork Deer Cr, and S Fork Deer Cr, illustrating how these intermittent waterways have carved the high plains of eastern Montana. This area is characterized by the Public Land Survey System grids of Township 18 and 19 North, where the terrain is marked by traditional section lines and a network of rural routes. Secondary roads such as Road 448 and Road 435 provide the primary access through this rangeland, connecting remote grazing lands to the larger regional infrastructure. The placement of the reservoir along the middle fork suggests the critical importance of water management in this arid agricultural environment during the early 21st century.
