The Yangtze River is the site of the Three Gorges Dam, a hydroelectric dam located in the Hubei province of China. The dam is the world's largest power station in terms of installed capacity and is the world's largest concrete structure. It has been in operation since 2003 and is an important part of China's energy infrastructure. The dam has had a significant impact on the environment and local communities, with some positive effects such as flood control and improved navigation, but also negative impacts such as displacement of people and destruction of habitats.
