BEIJING – Weeks of heavy rain have put the Three Gorges Dam, the largest hydropower project in the world, in danger of collapse putting 400 million people at risk.
The flooding has been described as the worst since 1949 with natural disasters being declared in 24 provinces and municipalities in the southwest and central China, especially in areas near the upper reaches of the Yangtze River and the Three Gorges Dam, causing the reservoir’s water level to exceed the flood control line.
The flood capacity of the dam is being approached, Zhao Yunfa, the deputy chief engineer of the overflow dispatch communications center at the Three Gorges Project, warned people:
“The flood storage capacity of the Three Gorges is limited. Do not pin your hopes on the Three Gorges Dam”
An estimated 400 million people live downstream of the Three Gorges Dam. The Ministry of Water Resources said that 148 rivers had exceeded warning levels. For the first time in history the Chongqing section of the Qijiang River Basin issued a red warning, signifying a flood of more than 33 feet. More than 40,000 people have so far been evacuated.
Three Gorges Dam
Made of concrete and steel, the dam is 7,661 feet long and the concrete dam wall is 594 feet high above the rock basis. The dam caused considerable controversy when it was built, displacing over a million people and submerging large areas of the Qutang, Wu and Xiling gorges for about 360 miles.
The dam flooded archaeological and cultural sites and caused significant ecological changes including an increased risk of landslides.
