Construction was completed on the Buffalo Bill Dam, then the tallest dam in the world, on the Shoshone River in the U.S. state of Wyoming.

Buffalo Bill Dam is a concrete arch-gravity dam on the Shoshone River in the U.S. state of Wyoming. Originally 325 feet (99 m), it was the tallest dam in the world when it opened in 1910; a 25-foot (7.6 m) extension was added in 1992 in one of the numerous changes and improvements to the structure and its support facilities, which include two full-time power generators and two seasonal operations added between 1920 and 1994, and a 2.8-mile (4.5 km) irrigation tunnel completed in 1939.
