@selmakitten: Floating Waterdrops Hooverdam 😍🥰 #hooverdam Hoover Dam, completed in 1936, was once the world’s largest concrete structure. Built during the Great Depression, it employed over 21,000 workers. The dam generates hydroelectric power for three states and holds back Lake Mead, the largest reservoir in the U.S. Fun fact: its concrete is still curing today!
