The Three Gorges Reservoir has increased its discharge volume as a severe flood peak is forming on the upper reaches of the Yangtze River. The world's largest dam now sees its highest water levels.
Located on the provincial border of Hubei Province with Chongqing municipality, the world's largest dam is expected to experience a peak flow of up to 70-thousand cubic meters per second.
Less than a day before the coming of the biggest peak to reach the dam at 8 am Tuesday morning, discharge was raised.
Cai Qihua, Yangtze Hydraulic Committee, said, To ease the pressure of middle and lower reaches, the discharge volume of the Three Gorges Dam will be increased from 34 thousand cubic meters per second to 40 thousand cubic meters per second.

The order for increasing discharge is the 14th readjustment for the dam this year. Experts want to make sure that the discharge will keep water at safe levels in lower reaches.
Cai said, Reducing the flow from 70 thousand to 40 thousand cubic meters per second, the Three Gorges Dam will effectively reduce the peak by about 40 percent. Thus greatly reducing the flood pressure downstream.
The discharge volume will be kept at 40 thousand cubic meters per second and may be adjusted depending on the rain situation in coming days.
