1983 Map of Foss Dam

About this map

Foss Reservoir dominates this landscape in western Oklahoma, where the impounded Washita River creates a central water body flanked by dedicated conservation and recreation zones. In the early 1980s, the western and northern reaches were managed as the Washita National Wildlife Refuge, while the eastern and southern shores formed Foss State Park. This division of the shoreline highlights the dual purpose of the reservoir for both habitat protection and public utility.
