China News Service, Yichang, July 18 (Reporter Guo Xiaoying) According to the Three Gorges Group, at 8 o'clock on the 18th, the inflow of the Three Gorges reservoir rose to 61,000 cubic meters per second and the outbound flow was 33,000 cubic meters per second, with a flood interception rate exceeding 45%. . This is the largest flood that reached the Three Gorges Reservoir since it entered the flood this year.
Recently, due to the heavy rainfall in the Jinsha River, Jialing River, Wujiang River and the Three Gorges region in the upper reaches of the Yangtze River, the inflow of the Three Gorges Reservoir increased rapidly from 28,100 cubic meters per second at 20 o'clock on the 15th to the 10 o'clock on the 17th. It has risen to 50,000 cubic meters per second. The Hydrology Bureau of the Yangtze River Water Conservancy Commission issued the "Yangtze River No. 2 Flood No. 2 in 2020" formed in the upper reaches of the Yangtze River in accordance with the "Regulations on the Numbering of Major River Floods in the Country."
According to the latest dispatch order of the Yangtze River Water Conservancy Commission, the Three Gorges Reservoir controls discharge at 32,500 cubic meters per second, and the peak shaving rate exceeds 40%, and the peak shaving effect is significant. A flood of 100 million cubic meters will reduce the pressure on the Three Gorges Flood Control.
Real-time data from the Hydrology Bureau of the Yangtze River Water Conservancy Commission showed that at 18:00 on the 18th, the inflow of the Three Gorges remained at 61,000 cubic meters per second, the outflow of reservoir was 34,500 cubic meters per second, the reservoir water level was 161.69 meters, and the flood limit level was nearly 17 meters.
In the follow-up, the Three Gorges Group Yangtze Power will strictly follow the overall dispatch and instruction requirements of the State Defence General Manager and the Yangtze Defence General Manager, and will make full use of the flood control benefits of the cascade hub by blocking peaks and staggering peaks. At the same time, it cooperates with the joint use of reservoir groups in the middle and upper reaches of the Yangtze River to provide a strong guarantee for flood control and flood control in the Yangtze River Basin.
