The sluice gates of the Three Gorges Dam are opened for the first time this year as flood water from heavy rain hurtles down the swollen Yangtze River in Yichang city, Central China's Hubei province, July 3, 2012. All 32 generators of China's Three Gorges Dam, the world's largest hydropower project, went into production on Monday, July 2 as flood season arrived. Located on the middle reaches of the Yangtze River, China's longest waterway, the Three Gorges Project consists of a 185-meter-high dam, a five-tier ship lock, a reservoir and 32 hydropower generators.
