Below the dam is the powerhouse that began operation in 1922 and was expanded in generating capacity in 1931.   Today, Units 1 and 2 remain in place in the power house but have been decommissioned. Unit 3 was removed in the 1990s and replaced with a new 3,000 kilowatt unit.

The National Park Service website says that, "... The dam was part of the Shoshone Project, which comprised a system of tunnels, canals, diversion dams, and Buffalo Bill Reservoir. Today, the project irrigates more than 93,000 acres, where principal crops are beans, alfalfa, oats, barley, and sugar beets. Although the number of irrigated acres never reached the 150,000 acres originally projected by project proponents, the figure has increased steadily over the years: from 25,753 acres in 1915 to 41,331 acres in 1928 to 77,560 acres in 1953."
