China’s Three Gorges Dam sees a 23-year record high water level. Landslides strike China in at least three areas, destroying homes and killing several people along the way.
Due to sustained rainfall in the upper reaches of the Yangtze River recently, the inflow volume of the Three Gorges Reservoir exceeded 22,000 cubic meters per second and embraced three floods of over 40,000 cubic meters per second.
In addition to flood control, Three Gorges Reservoir regulated the discharge volume in lock step with the power units at full capacity, managing to control the water level at the reservoir to increase gradually.
Three Gorges Project, operated by China Three Gorges Corporation (CTG), announced that it had connected all of its 34 power units to the grid on August 30, achieving full-load operation for the first time in 2021 with a total output of 22.5 GW.
TThree Gorges Dam opens a hole for flood discharge
On September 7, the Three Gorges Dam opened a hole for flood discharge, according to the state media China News.
Affected by heavy rainfall, the inflow of the Mintuo River, Jialing River and the Three Gorges area in the upper reaches of the Yangtze River increased. At 14:00 on Sept 6, the flow into the Three Gorges Reservoir rose to 54,000 cubic meters per second.
According to the “Regulations on Flood Numbering of Major Rivers in the Country”, the flood numbering standard was reached, and the “Yangtze River No. 1 Flood in 2021” was formed in the upper reaches of the Yangtze River.
The Three Gorges Reservoir opened a spillway at 19:00 on the 6th, and the outflow flow rate was 28,000 cubic meters per second (including the generating capacity of the unit).
China on guard against flooding as Yangtze River swells
Chinese authorities have called for rigorous anti-flooding measures along the Yangtze River as water levels continue to rise following heavy rainfall, the Ministry of Water Resources said on Monday.
The flow of water at the Three Gorges reservoir has increased rapidly, reaching 54,000 cubic meters per second as of 2 p.m. Monday.
The ministry said it is maintaining its response at Level IV, and has called for more anti-flooding measures at the Three Gorges reservoir and other main projects along the river.
China has a four-tier flood-control emergency-response system, with level I being the most severe.
