2012 Map of Needle Reservoir

About this map

Antelope Knoll rises above the high desert landscape of Sweetwater County, marking a terrain defined by its critical water management features and seasonal drainages. The map reveals a network of man-made catchments essential for ranching and wildlife in this arid environment, including the centrally located Big Hollow Reservoir, Badlands Reservoir, and the namesake Needle Reservoir to the east. These water sources are connected by a system of unpaved roads and natural features such as Tin Can Draw and Cattail Draw. The presence of the Staley Corral in the southern portion of the quadrangle highlights the area's continued use for livestock and land management, where the sparse infrastructure is dictated by the availability of water and the undulating breaks of the Wyoming basin.
