2012 Map of Fontenelle Reservoir SE

About this map

The Green River flows through this high desert region of Sweetwater County, dominated by the expansive waters of the Fontenelle Reservoir. This 2012 survey illustrates the modern hydrology and infrastructure of the area, showing where the river's course is interrupted by the reservoir's southern reach. To the west, the sharp elevation changes of Case Knife Canyon create a distinct geological break in the landscape. Local history and genealogy interest is anchored by the Whitman Cem, located south of the reservoir's primary basin. The map tracks a network of rural access routes, including Co Line Rd and 18 Mile Rd, which navigate the arid terrain surrounding the reservoir. These roads serve as the primary arteries for this sparsely populated section of Wyoming, connecting isolated landmarks and the managed water resources of the Upper Green River Basin.
