China News Service, Yichang, September 7 (Reporter Guo Xiaoying) At 8 o'clock on the 7th, the flow of the Three Gorges Reservoir was 54,000 cubic meters per second.

From 19:00 on the 6th, the Three Gorges Dam opened a spillway, and the outflow flow rate was 28,000 cubic meters per second (including the generating capacity of the generating units).

  Affected by the increase in water inflows from the upper reaches and sections, at 14:00 on the 6th, the flow of 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", it reached the flood numbering standard, "Yangtze River No. 1 Flood in 2021" Formed in the upper reaches of the Yangtze River.

  On the 6th, the Yangtze River Water Resources Commission of the Ministry of Water Resources dispatched the cascade reservoirs in the lower reaches of the Jinsha River to fully arrest the floods in the Jinsha River, and issued a dispatch order to increase the outflow of the Three Gorges Reservoir to about 28,000 cubic meters per second.

Starting at 19:00 on the 6th, the Three Gorges Dam opened a spillway.

  According to the real-time water conditions of the Yangtze River Hydrological Bureau, from 20 am on the 6th to 2 am on the 7th, the flow of the Three Gorges Reservoir was 55,000 cubic meters per second, and the peak cut rate of the Three Gorges Reservoir was 50%, effectively alleviating the flood control pressure in the middle and lower reaches of the Yangtze River.

  It is reported that before the arrival of this flood, the Three Gorges Project of the Three Gorges Group's Yangtze River Electric Power Company had a consultation with the hydrometeorological forecasts of relevant units, and with the help of automatic telemetering stations and other water and rain forecasting systems, it was predicted that a numbered flood would occur in the Yangtze River basin one week in advance. , And make relevant flood prevention preparations in advance.

In response to the "Yangtze River No. 1 Flood in 2021", the safety of the Three Gorges Project and the Three Gorges Reservoir were not affected.

  During the autumn flood season, the Three Gorges Group will continue to pay close attention to changes in water and rain conditions in the basin, make accurate forecasts, and dispatch accurately. At the same time, it will increase inspections of power production equipment, flood discharge facilities, drainage system operation status, and hole plugging to ensure electromechanical equipment and flood discharge. The facilities are operating safely and reliably, and the key tasks such as flood control, safe production, energy supply, and annual water storage will be further improved.

  The Three Gorges Maritime Safety Administration and the Yichang Maritime Safety Administration have issued a flood level four (blue) water traffic safety warning, requiring all ships and ship units to do a good job in safety under conditions of large flow, pay close attention to changes in flow, and do a good job in securing ships and stockings. , Strengthen the mooring duty to prevent the phenomenon of anchor removal.

The maritime department strengthens safety publicity and on-site supervision to ensure the safety of water traffic during the flood season.
