As southern China sees some of its worst flooding in 80 years, videos on internet taken by local Chinese have surfaced showing extreme quantities of water inundating 10 provinces and cities, threatening the vaunted Three Gorges Dam.

As China's Yangzi River Basin enters its flood season, the upper reaches of the Three Gorges Dam are seeing the highest flood levels since 1940. Weather China has issued its highest warning for flooding and rain for the middle and lower reaches of the Yangzi River to Guizhou.

The rainfall is expected to peak on Tuesday and Wednesday (June 23 and 24). Flood warnings have been issued in more than 10 provinces and municipalities in China, including Guizhou, Chongqing, Hunan, Hubei, Jiangxi, Anhui, Jiangsu, Zhejiang, Shanghai, and Guangxi.

Many people are believed to be trapped by the floodwaters in the province's Bajiao Township. In Tongren City in Guizhou's Yanhe Tujia Autonomous County, a landslide has sealed off the highway tunnel to Guanzhou Township where houses and shops are also swamped with floodwaters.

The Guizhou Meteorological Bureau has continued to issue red warnings for torrential rain in Wuchuan County, Zheng'an County, Yanhe County, and Tongzi County. In addition, 13 counties under the jurisdiction of Zunyi City and Tongren City have issued yellow flood warnings.

Given that the Qijiang is a tributary of the Yangzi River, the Three Gorges Dam will be facing its biggest test since it opened in 2003. At least one Chinese scientist, hydrologist Wang Weiluo, is questioning the dam's integrity, given numerous cracks observed and substandard concrete used in construction.

Scientist Wang Weiluo said that the Three Gorges Dam was not as stable as many people thought. Besides, Mr. Wang pointed out that the design, construction and quality assessment of the dam were all done by the same expert teams and the project completion time was too fast.

At a press conference on June 10, Chinese Vice Minister of Water Resources Ye Jianchun also acknowledged that the water level on at least 148 rivers in the country exceeded the warning level, proving that the flood control capacity of The Three Gorges Dam at a limit.

In addition, Mr. Wang also said that the biggest concern was the cracks and the quality of concrete did not meet the standards during the construction of the Three Gorges Dam. According to him, if the dam breaks, there will be catastrophic consequences for people living in the lower Changjiang River and warning people to prepare for evacuation as soon as possible.

According to the online television channel CNTV, the water level inside the Three Gorges dam was over 2 meters higher than the flood control standard.

Xinhua cited data from China Three Gorges Dam Group, which said that in the past 17 years, a total of 873,800 vessels carrying 12.23 million passengers and 1.46 billion tons of cargo had stopped by the Three Gorges Dam.
