1. The Hoover Dam, formerly known as the Boulder Dam, is located at the border of Arizona and Nevada, in Black Canyon on the Colorado River. It was constructed by the United States between 1930 and 1936 and is the highest concrete arch dam in the country. The dam creates one of the largest man-made lakes in the world, the 115-mile (185 km) long Lake Mead.
2. Serving multiple purposes, the Hoover Dam is used for flood control, silt control, electricity generation, agricultural irrigation, and domestic water supply. It has also become a significant tourist destination, attracting nearly one million visitors annually.
3. The dam stands at a height of 726 feet (221 meters) and spans 1,244 feet (379 meters) in length. It contains 440,000 cubic yards (336,000 cubic meters) of concrete. Four reinforced concrete intake towers are situated on the dam, which channel water into large pressure pipes.
4. Water flows 500 feet (150 meters) down through these pipes to the dam's power plant at the bottom, where it drives 17 vertical Francis turbines, generating a total installed capacity of 2,080 megawatts. More than half of this electricity is supplied to the South California Water District, including cities like Los Angeles, with the remainder going to Nevada and Arizona.
5. The dam and reservoir are owned and managed by the U.S. Department of the Interior's Bureau of Reclamation.
6. The Hoover Dam was named in honor of President Herbert Hoover, who played a crucial role in the dam's construction during his presidency (1929-1933) and as Secretary of Commerce (1920) in ensuring the project's success. Although Congress formally named the dam after Hoover in 1931, it was still commonly referred to as the Boulder Dam by Presidents Roosevelt and Truman until the construction phase.
7. A federal highway crosses the dam since its construction, serving both visitors and providing access between Nevada and Arizona.
8. With the increasing popularity of the dam and the surrounding Lake Mead Recreation Area, and following the security concerns post-9/11, a long-planned bypass road was constructed. In October 2010, the longest bridge in the northern United States, spanning 1,060 feet (322 meters), opened for traffic, offering views of the Hoover Dam. The old road across the dam's top was preserved for visitor access.
9. The translation task was quite exhausting due to the numerous technical terms involved.
