The Three Gorges Reservoir (TGR) received an inflow of 53,000 cubic meters per second at 14:00 on July 5th, marking theformation of the First Yangtze Flood in 2018.
Wuhan, July, 6th(Xinhua News Agency)--The impoundment of the Three Gorges Reservoir has reached 1.26 billion cubic meters at 16:00 on July 6th, with a peak clipping rate of 24.5%.
On July 6th, the reporter learned from the China Three Gorges Group that the inflow of the Three Gorges Reservoir rose rapidly from 27,500 cubic meters per second at 8:00 on July 3rdto 51,000 cubic meters per second at 8:00 on July 5th, reaching the standard sofnational regulations of flood flow of main rivers.The flood was numbered by the Yangtze River Flood Control and Drought Relief Head quartersas First Yangtze Flood,which shows its formation in the upstream.
In order to reserve flood control storage for the later floods, the Three Gorges Power Station released water at 21:00 on July 4th, and the outflow volume was gradually increased, rising to 40,000 cubic meters per second at 8:00 on July 5th. The water level of the Three Gorges Reservoir rose from 145.06 meters at 10:00 on July 4thto 147.61 meters at 16:00 on July 6th.
Cao Guangrong,Deputy Director of the Three Gorges Water Conservancy Cascade Dispatching and Communication Center, said the peak clipping rate of the Three Gorges Reservoir had reached 24.5% and the impoundment of flood was 1.26 billion cubic meters at 16:00 on July 6th, which effectively guaranteed the safety of the downstream flood control, keeping the water level of Jingjiang River and the Lianhuatang of Chenglingji below the warning water level. At present, about 21 billion cubic meters of flood control storage is reserved in the TGR and 5 billion cubic meters in Xiluodu and Xiangjiaba reservoirs in the upper stream of the Yangtze River.
Cao said that next step is to strictly follow the orders of the Yangtze River Flood Control and Drought Relief Headquarters, with more frequent water and rain forecast and meetings to timely provide the warning information to departments of the flood control and navigation and the inspection of equipment and facilities will be increased to guarantee the flood control safety.
