2017 Map of Big Sandy Reservoir

About this map

Big Sandy Reservoir dominates this landscape on the border of Sweetwater and Sublette counties. Fed by the Big Sandy River from the north, this water feature is a central element in an otherwise arid expanse of high-elevation terrain. The map details the local road network connecting this remote area, including the prominent route of 191 which runs parallel to the river valley. To the south, Co Rd 28 provides access to the reservoir's edge. The survey also clearly marks the administrative boundary of Sublette Co Sweetwater Co, offering a precise record of how these county lines intersect with the natural drainage and modern infrastructure of the Green River Basin in the mid-2010s.
