Affected by recent rainfall and upstream inflow, the water level of the middle and lower reaches of the Yangtze River and the two lakes continued to rise. The Ministry of water resources and other places along the Yangtze River intensively started or raised the emergency response level for flood and drought disaster prevention.

Key words 1: emergency response

Yesterday (4), the Ministry of water resources upgraded the level IV emergency response for flood and drought disaster prevention to level III, and sent four working groups to Chongqing, Hubei, Jiangsu and Zhejiang to guide local flood control work. The Yangtze River Water Conservancy Commission of the Ministry of water resources and the Taihu Lake Basin Authority also upgraded the level IV emergency response to flood and drought disaster prevention to level III respectively. In addition, affected by the No.1 flood of the Yangtze River in 2020 and the continuous rainfall in Northern Hunan Province, the water resources department of Hunan Province decided to upgrade the emergency response of flood and drought disaster prevention from level IV to level III at 8:00 p.m. yesterday (April 4). Anhui Provincial Water Resources Department decided to upgrade the emergency response of flood and drought disaster prevention to grade III from 18:00 on July 3. In addition, at 9:30 today (May 5), the Hubei Provincial Meteorological Bureau upgraded the emergency response for major meteorological disasters (rainstorms) from level IV to level III.

Key word 2: discharge of Three Gorges Reservoir

Yesterday (4), the Yangtze River Commission of the Ministry of water resources held a meeting to analyze and judge the development trend of flood situation. After the meeting, the Yangtze River Commission issued a dispatching order to temporarily reduce the outflow of the Three Gorges reservoir to 30000 cubic meters per second from 6:00 today, and timely evacuate some ships stranded in the Three Gorges Gezhouba section, so as to ensure the safety of flood control and navigation At the same time, the Xiluodu, Xiangjiaba and cascade reservoirs in the middle reaches of Jinsha River will be adjusted simultaneously to increase the blocking and storage efforts, appropriately reduce the inflow of the Three Gorges, and jointly reduce the flood control pressure in the middle and lower reaches of the Three Gorges. In the follow-up, according to the changes of water and rain, rolling consultation will be conducted to adjust the operation scheme in time.

Key words 3: inflow of Three Gorges Reservoir

According to the Three Gorges group, at 10:00 on July 2, the Three Gorges Reservoir ushered in the No.1 flood of the Yangtze River in 2020.

As of 8 a.m. yesterday (April 4), the inflow of the Three Gorges reservoir had retreated to 31000 cubic meters per second, and the No. 1 flood had passed through the Three Gorges Dam safely.

Key words 4: water retaining capacity

According to the information released by the Three Gorges group, in accordance with the regulation order of the Yangtze River Commission, the discharge of the Three Gorges reservoir is controlled at an average of 35000 cubic meters per second per day. Among the reservoirs, the maximum storage capacity of the Three Gorges reservoir is 18000 cubic meters per second, and the peak cutting rate is more than 30%. Yesterday (4 days), the water level of the Three Gorges Reservoir rose to 149.37 meters, and the water retaining capacity was nearly 1.6 billion cubic meters The flood control pressure in the middle and lower reaches of the Yangtze River is effectively relieved, and the water level of Shashi station in Jingjiang reach is avoided. According to the latest hydrometeorological forecast, the Three Gorges reservoir is expected to usher in a new round of flood process in the first ten days of July.
