Hoover Dam Hoover Dam, originally known as Boulder Dam from 1933 to 1947, when it was officially renamed Hoover Dam by a joint resolution of Congress, is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Nevada and Arizona. It was constructed between 1931 and 1936 during the Great Depression and was dedicated on September 30, 1935, by President Franklin D. Roosevelt. Its construction was the result of a massive effort involving thousands of workers, and cost over one hundred lives. The dam was named after President Herbert Hoover.
Fairbairn Dam The Fairbairn Dam is an earthfill-filled embankment dam across the Nogoa River, located southwest of Emerald in Central Queensland, Australia. Constructed in 1972 for the primary purpose of irrigation, the impoundment created by the dam serves as one the major potable water supplies for the region and assists with some flood mitigation. Lake Maraboon with an active capacity of 1301000 ML was formed by damming of the Nogoa River, and, in 2008, was Queensland's second largest dam. Maraboon is the Aboriginal for "where the black ducks fly".
