2021 Map of McMaster Reservoir

About this map

The Niobrara River meanders across this high plains landscape of Niobrara County, defining the drainage patterns of a region dedicated to ranching and water management. This contemporary survey highlights the essential role of artificial water storage in the Wyoming interior, featuring McMaster Reservoir and the adjacent McMaster Reservoir Number 4. These sites, along with Christian Reservoir and Dean Reservoir Number 1, provide critical water resources for the surrounding arid terrain. The map is further divided by the rural McMaster Rd, which provides access through the expansive sections of the Public Land Survey System. Streams like Duck Creek (also labeled as Duck Cr) feed into the larger river system, illustrating the subtle topography of the northeastern Wyoming plains.
