The largest dam in the world is the Three Gorges Dam located on the Yangtze River in China. It is an immense hydroelectric gravity dam, completed in 2012, with a total generating capacity of about 22,500 megawatts. The dam is approximately 2,335 meters (7,660 feet) long and 185 meters (607 feet) high, making it a vital piece of infrastructure for flood control, electricity generation, and river navigation. While it has significantly contributed to energy production in China, the project also raised concerns regarding environmental impacts and the displacement of local communities.
