Buffalo Bill Dam, on the Shoshone River about 6 miles upstream from Cody, WY, is a concrete arch structure of constant radius. The structural height is 350 feet and the volume is 87,515 cubic yards. It is one of the first high concrete dams built in the United States. The reservoir impounds 646,565 acre-feet of water. The Shoshone Powerplant is near the base of Buffalo Bill Dam. 

Competent granitic rock of pre-Cambrian age. Some major to minor jointing and occasional thin shear seams are present. No critical unstable rock masses are known to be present in the immediate vicinity. Very little plucking of rock fragments occurred in the old unlined spillway tunnel.
