2015 Map of McMaster Reservoir

About this map

The Niobrara River carves a path through this section of eastern Wyoming, where water management defines the high plains landscape. This 2015 survey highlights the critical infrastructure required for ranching and agriculture in Niobrara County, featuring several named catchments including McMaster Reservoir, Christian Reservoir, and Dean Reservoir Number 1. These man-made features, fed by the seasonal flows of Duck Cr, illustrate the historical and ongoing efforts to capture runoff in an arid environment. The map shows a region organized by the Public Land Survey System, with the north-south transit of McMaster Rd and the east-west corridor of Route 20 serving as the primary arteries for local commerce and land access across the township and range boundaries of the T31N and T32N blocks.
