Three Gorges Dam
Videos
The Three Gorges Dam is a hydroelectric gravity dam that spans the Yangtze River near Sandouping in Yiling District, Yichang, Hubei province, central China, downstream of the Three Gorges. The world's largest power station in terms of installed capacity (22,500 MW), the Three Gorges Dam generates 95±20 TWh of electricity per year on average, depending on the amount of precipitation in the river basin. After the extensive monsoon rainfalls of 2020, the dam's annual production reached nearly 112 TWh, breaking the previous world record of ~103 TWh set by Itaipu Dam in 2016.

In his poem "Swimming" (1956), engraved on the 1954 Flood Memorial in Wuhan, Mao Zedong envisions "A Great Stone Wall, to catch the clouds and rains of Wushan as the fall" as "A Great lake shall rise upon the gorge!".

The 1931 China floods, or the 1931 Yangtze–Huai River floods, occurred from June to August 1931 in China, hitting major cities such as Wuhan, Nanjing and beyond, and eventually culminated in a dike breach along Lake Gaoyou on 25 August 1931.
