2017 Map of McMaster Reservoir

About this map

The Niobrara River winds through this high plains landscape of Niobrara County, anchoring a terrain defined by subtle drainage patterns and seasonal water storage. Recent decades have seen the development of essential water management features, including the namesake McMaster Reservoir in the southeast and Christian Reservoir further north. These water bodies reflect the ongoing importance of livestock and resource management in this corner of Wyoming. The survey area is bisected by McMaster Rd, a primary transit artery connecting these remote sections. Tributaries like Duck Creek and Duck Cr channel the scarce precipitation toward the Niobrara, illustrating the natural watercourse system that has shaped land use across these townships since the early days of ranching.
