1974 Map of Mc Master Reservoir

About this map

The Niobrara River carves a winding path across this portion of Niobrara County, creating a valley that dictates the local infrastructure of the mid-1970s. Running parallel to the river's northern banks, the Chicago and North Western railroad provides a clear east-west corridor through the high plains landscape. This proximity of rail and water defines the land use in the quadrangle, where the McMaster Reservoir serves as a critical water feature for the surrounding area. Beyond the river valley, the terrain is dotted with signs of local industry and resource extraction, including several noted wells and a drill hole, suggesting active exploration or maintenance of water and mineral rights during this era. The presence of Duck Creek further illustrates the drainage patterns that have historically shaped this Wyoming ranching country.
