2010 Map of Foss Dam

About this map

Foss Reservoir dominates this landscape in Custer County, representing a major hydraulic engineering project on the Washita River. Completed by the Foss Dam, the reservoir's irregular shoreline creates distinctive features like Cheyenne Point and recreational access via Sandy Beach Rd. The map reveals an extensive water management system beyond the main impoundment, including numerous smaller reservoirs and dams such as the Butler Laterals Site 2 Reservoir and Soldier Creek Watershed Site 8 Reservoir, which serve the agricultural lands of western Oklahoma. For those looking for local history, the Edwardsville Cemetery sits near the eastern shore of the reservoir, a quiet landmark preserved as the surrounding valley was transformed by the rising waters. The terrain is further defined by several tributaries, including Cutberth Creek, Comet Creek, and Little Soldier Creek, which feed into the primary basin.
