3 gorge large dams, be located in Chinese Hubei to save 3 bottles of level ground of Yichang city to press down churchyard, be apart from dam of downstream Ge Zhou project of key water control project 38 kilometers, it is current world the biggest irrigation works sends electrical engineering Cheng -- of reservoir of the core landscape of area of travel of large dams of the main body project of 3 gorge hydroelectric station, 3 gorge, 3 gorge east upright. Project of 3 gorge large dams includes main body building and diversion project two parts, make an appointment with 3335m endlong, dam is 185 meters expensive, project total investment is 95.46 billion RMB, build at beginning construction formally on December 14, 1994, all fronts built a success on May 20, 2006. Classics country defends total approval, 3 gorge reservoir on September 10, 2011 zero hour starts 175 meters of experimental store water formally the 4th times, to 18 days 19 when, reservoir water level already achieved 160.18 meters. On July 23, 2012, open of 3 gorge hub flood discharge of deep aperture of 7 flood discharge. Upper reaches comes discharge increase sharply comes every second 46 thousand stere. On July 24, 2012, discharge of put in storage of 3 gorge large dams amounts to seventy-one thousand two hundred stere / second, it is the biggest flood peak that since 3 gorge reservoir builds a warehouse, encounters. Large dams of 3 gorge hydroelectric station is 185 meters tall, normal harbour water level 175 meters, reservoir is 2335 meters long, the static state invests one hundred and thirty-five billion two hundred and sixty-six million RMB [1] , install 32 stand-alone capacity to be the aircrew of water and electricity of 700 thousand kilowatt. 3 gorge power station aircrew of last water and electricity, on July 4, 2012 put into production, this is meant, installed capacity reachs the 3 gorge hydroelectric station of 22.4 million kilowatt, already became the hydroelectric station with the greatest whole world and base of clean energy production on July 4, 2012. In December 2015, 3 gorge large dams is selected the Yangtse River 3 gorge one of new landscape of 30 optimal travel.
