Originally authorized by U.S. President Franklin Roosevelt in 1933, construction on the Fort Peck Dam employed over 11,000 workers at its peak in 1939. The dam, named for a 19th-century trading post, was completed in 1940, and began generating electricity in July 1943. The site is located near Glasgow, Montana, and the community of Fort Peck, Montana originally developed as a boomtowm during the dam's construction. The dam presently has a power-generating capacity of 185,250 kilowatts.
