Floodwater gushes through the sluice gates of the Danjiangkou reservoir, which is on the middle section of the south-north water transfer project, in Wuhan, Central China's Hubei province, July 27, 2010. The reservoir on the Hanjiang River, a left tributary of the Yangtze River, has helped buffer the flood, which peaked July 19, when the water flow rate reached 27,500 cubic meters per second. It greatly reduced the burden on the Three Gorges Dam. [Photo/Xinhua]
