1. Bonneville Dam.
Constructed between 1933 and 1938, Bonneville Dam originally consisted of a spillway 1,450 feet long, 132 feet wide at its base, and 197 feet high above the lowest bedrock; a powerhouse 1,027 feet long and 190 feet in width and height; and a navigation lock with a chamber 500 feet long and 76 feet wide. The gravity concrete spillway contained 18 steel gates that were fifty feet wide. (Submitted on February 15, 2018, by Cosmos Mariner of Cape Canaveral, Florida.)
2. Bonneville Dam.
Prior to the New Deal, development of the Columbia River with flood control, hydroelectricity, navigation and irrigation was deemed as important. In 1929, the US Army Corps of Engineers published the 308 Report that recommended 10 dams on the river but no action was taken until the Franklin D. Roosevelt administration and the New Deal. During this period America was in the Great Depression, and the dam's construction provided jobs and other economic benefits to the Pacific Northwest. Inexpensive hydroelectricity gave rise to a strong aluminum industry in the area. (Submitted on February 16, 2018, by Cosmos Mariner of Cape Canaveral, Florida.)
