The Ministry of Water Resources launched the summer of 2022 to lead Jiang Jitai water volume dispatch to ensure water supply safety in Taihu Lake Basin

Since June this year, the rainfall in the Taihu Lake Basin is more than 70 % less than the same period of the same year, especially the rainfall during the rainy period is serious, resulting in the continued decline in the water level of Taihu Lake. At 10:00 on July 16th, Taihu Waterfall was 3.16 meters, which was 0.40 meters lower than the same period of the year, the lowest in the same period in the past 20 years. According to meteorological predictions, there will be no obvious rainfall process in the Taihu Lake Basin in the next ten days. In addition to the continuous high temperature impact, the water level in Taihu will continue to decline, the liquidity of the water body will weaken, and the risk of cyanobacteria water will increase.

On July 16th, Liu Weiping, deputy minister of the Ministry of Water Resources, presided over the chamber of commerce to analyze and judge the drought situation of the Taihu Lake Basin. In view of the current low water level in Taihu Lake and still showing a downward trend, it has reached the water regulation stipulated in the "Taihu Basin Flood and Water Quantity Schedules". Start the condition and decide to start at 16:00 on July 16th to introduce the amount of water in the summer of 2022. The Ministry of Water Conservancy issued a notice requesting the Taihu Basin Administration and Shanghai, Jiangsu, Zhejiang Province (municipality) Water Conservancy (Water Affairs) Hall (Water) Department (Bureau) Department (Bureau), pay close attention to weather changes, strengthen rainwater conditions monitoring forecast and water engineering scheduling, and do a good job of monitoring and monitoring of water quality and monitoring and monitoring of water quality. Prevent and control, and orderly carry out the work of leading the river in the river to achieve multiple goals such as flood prevention and safety, water supply and development, and improving the water environment. During the water transfer, if a sudden heavy rainfall is encountered, it is predicted that the water level of the Taihu water level exceeds the water level. Set up water to ensure flood prevention safety.

In order to ensure the safety of water supply in the water source of Taihu Lake and improve the water environment of Taihu and surrounding areas, according to the dispatch mechanism of the water volume of the river, the Taihu Basin Management Bureau of the Ministry of Water Conservancy, together with Shanghai, Jiangsu, Zhejiang provinces (municipalities), water conservancy (water affairs) departments (bureaus) "Summer 2022 Summer Leading Jiang Jitai Water Plan". The first is the joint scheduling of the Changshu Water Conservancy Hub of Wangyu River. The water volume of the Yangtze River is 1,000 to 16 million cubic meters of water. The second is that the Tai Pu gate is not less than 60 cubic meters to supply water to Zhejiang, Shanghai and other places downstream. The third is to enable the control project of the West Bank of Wangyu River to avoid inferior water on the west bank to enter Taihu Lake through Wangyu River. According to the results of the scheduling rehearsal, the implementation of the amount of water in the river Jitai water can improve the water environment of the Taihu Lake, increase the water supply supply of the watershed, meet the water demand for water around the Taihu Lake, and effectively reduce the impact and loss of high temperature and drought around Taihu Lake.
