China News Service, Yichang, September 11 (Reporter Guo Xiaoying) According to the official WeChat news of the Three Gorges Group, the 175-meter experimental storage of the Three Gorges Reservoir at the end of the 2020 flood season has officially started at 0:00 on the 10th.
The initial storage level of the water storage is 154.83 meters, and the storage capacity is 16.612 billion cubic meters.
175 meters is the normal water storage level designed for the Three Gorges Project. The Three Gorges Project will store water to 175 meters at the end of the flood season each year, and will gradually release and free up the storage capacity during the dry season to the next flood season to maximize navigation, power generation, water supply, and drought resistance. Comprehensive benefits in such aspects.
Since 2010, the Three Gorges Reservoir has achieved the 175-meter test storage target for 10 consecutive years.
According to the "Approval from the Ministry of Water Resources on the Implementation Plan of the Three Gorges Reservoir Experimental Water Storage in 2020", during this water storage process, the water storage level will be controlled from 162 meters to 165 meters on September 30, and it will be stored to 175 meters at the end of October or November. .
The control of the specific water level at each stage will be appropriately adjusted according to the comprehensive needs of the upstream and downstream real-time rainfall, flood control situation, and water resource utilization.
Since the flood season this year, the Three Gorges Reservoir has successfully dealt with 12 floods of more than 30,000 cubic meters per second and withstood the test of the largest flood peak since the construction of the reservoir.
The monitoring results of the Three Gorges Group Basin Management Center show that the hydraulic structures, flood discharge facilities, and power generation equipment of the Three Gorges Project are in normal operation, and the dam's various operating indicators are good.
The Yangtze River Three Gorges Navigation Management Bureau announced that it will strengthen equipment maintenance and operation management during the water storage period, adjust the operation mode of the Three Gorges ship lock in a timely manner, release the ship lock and the ship lift water-retaining beam according to the water level, and ensure that the ship lock and ship lift are normal and efficient run.
At the same time, do a good job in the linkage control and safety inspection of ships passing the lock, strengthen the safety inspection of the anchorages, docks, ports, and inter-passenger ferries in the Three Gorges Dam area, timely adjust the channel signs and anchoring facilities, and do a good job in the order management of the ships waiting to be locked to ensure the Three Gorges Dam Navigation in the district is safe and orderly.
