Buffalo Bill Dam, Wyoming

Construction of Buffalo Bill Dam, completed in 1910 six miles west of Cody, Wyoming, was the key that opened about 90,000 acres in northwestern Wyoming to irrigated farming. Its construction was slowed by engineering difficulties and labor strife, but when it was finished stood as an engineering marvel, one of the first concrete arch dams built in the United States and the tallest dam in the world at the time.

History of Glendo Dam

Before Glendo Dam could be built on the North Platte River in Platte County, Wyoming, complicated water-rights disputes had to be settled among Wyoming, Nebraska and Colorado and the settlement approved by the U.S. Supreme Court. The process took more than a decade, and shows the difficulties of allocating water in the arid West. The earthfill dam, nearly 2,100 feet long and 190 feet high, was completed in the fall of 1957. It stores water for irrigation and recreation, controls floods, reduces sedimentation in the Guernsey reservoir downstream and produces hydropower.

Alcova Dam and Reservoir

Alcova Dam, a Bureau of Reclamation project, was completed in 1937. The reservoir opened in 1938 and a power plant was completed in 1955. The $20 million dam project didn’t achieve the high expectations of immense wealth that were forecast at the time of its inception, but continues to provide irrigation water for farmers and ranchers and generates hydropower for the area. Alcova Reservoir offers fishing, boating, camping and swimming opportunities for visitors.
