1969 Map of Big Sandy Reservoir

USGS Topo · Published 1973

About this map

Big Sandy Reservoir dominates the landscape at the southern edge of Sublette Co, where the high desert terrain meets the irrigation needs of the late 1960s. This survey, based on 1968 aerial photography, captures the engineered hydrology of the Big Sandy River as it is impounded by the Big Sandy Dam. The map provides a technical view of water management in this arid region, featuring a Gaging Sta north of the reservoir and a Flowing Well to the south. Crossing the boundary into Sweetwater Co, the map documents the transition from riverine flow to a large standing water body, illustrating the significant modification of the natural drainage system for agricultural or resource purposes during this era.
