Deadwood Dam is located in west-central Idaho on the Deadwood River about 25 miles above its confluence with the South Fork of the Payette River and about 90 miles above Black Canyon Diversion Dam. The damsite is located in a narrow canyon where the Deadwood River has cut into granite bedrock, approximately 53 miles northeast of Boise, Idaho. The dam lies on the western slope of the Sawtooth Mountains. Deadwood Dam is a concrete-arch structure, was completed in 1931, and provides a regulated flow for the powerplant at Black Canyon Diversion Dam and for irrigation in the Payette Division and Emmett Irrigation District.
