2015 Map of Big Sandy Reservoir SE

About this map

Sublette Cutoff traces through this high plains landscape at the border of Sublette and Sweetwater counties, preserving the path of a historic westward migration route. This 2015 survey details a remote stretch of the Wyoming basin where water management is central to the landscape, evidenced by Little Sandy Reservoir Number 2 and Little Sandy Reservoir Number 3. These basins, along with the meandering course of Little Sandy Creek, represent the critical hydrography required for ranching and transit in an otherwise arid environment. The map provides precise topographic data for the townships of t27n r105w and t27n r104w, showing how modern infrastructure like CR-108 follows the long-established natural corridors used by early travelers.
