Willwood Dam
5 miles southwest of Ralston

The Willwood Dam diverts water from the Shoshone River to irrigate 11,400 acres of land on the Willwood Division of the Project, which was settled beginning in 1927.

Construction of the 70-foot-high dam began in 1922, and work was completed just a year later. Work on the canal, located across the river looking to the East, was completed in the spring of 1927, and the first unit homesteaders received water for their new farms on April 21, 1928.

The dam is located 22 miles downstream from Buffalo Bill Dam.
