China News Agency, Wuhan, August 16 (Reporter Zhang Qin) The reporter learned from the Yangtze River Water Conservancy Commission of the Ministry of Water Resources (hereinafter referred to as the "Changjiang River Commission") on the 16th that from August 1 to 15, the Yangtze River Commission coordinated drought-relief water and high temperature power supply. According to the demand, the controlled reservoir groups in the basin are scheduled to supply about 5.3 billion cubic meters of water to the middle and lower reaches in an orderly manner. The upstream reservoir groups and the middle reaches of the reservoir group supply 3.66 billion cubic meters and 1.64 billion cubic meters of water respectively, of which the Three Gorges Reservoir supplies a total of 1.09 billion to the middle and lower reaches. cubic meter.
The Yangtze River Commission issued a dispatch order on the 16th, dispatching the Three Gorges Reservoir to replenish water to the middle and lower reaches of the Yangtze River, and controlling the water level of the reservoir to not be lower than 146 meters on the 21st.
According to estimates, from the 16th to the 21st, the Three Gorges Reservoir will be replenished through the cascade reservoirs in the lower reaches of the Jinsha River, and the reservoirs in the upper reaches of the Yangtze River will replenish about 1 billion cubic meters of water to the middle and lower reaches.
Since July, most parts of the Yangtze River Basin have experienced continuous high temperature and little rain, and some provinces and cities have experienced droughts of varying degrees.
The water level in many parts of the Yangtze River is the lowest in the history of the same period since the hydrological record, and there is a rare phenomenon of "reverse dryness during the flood season".
According to the hydrometeorological forecast, in the next week, there will be local light or moderate rain in the western part of the upper reaches of the Yangtze River and the Han River, and there will be no obvious rainfall process in the rest of the Yangtze River Basin. It is expected that the drought in Sichuan, Chongqing, Dongting Lake, Poyang Lake and the middle and lower reaches of the Yangtze River will continue to develop. The drought defense situation in the basin is still grim.
According to the requirements of the Yangtze River Defense General Administration for consultations on the 15th and 16th, relevant departments and units are paying close attention to the water and rain conditions in the basin, conducting rolling consultations to study and judge the development trend of drought conditions, and do a good job in drought monitoring, forecasting and early warning. The Three Gorges Reservoir in the upper reaches of the Yangtze River with the Three Gorges Reservoir as the core and the Dongting Lake "Four Rivers" and Poyang Lake "Five Rivers" reservoirs supply water for the downstream, ensuring the safety of drinking water for the people in the arid areas, and achieving the precise connection between the scheduling of the reservoir groups and the agricultural irrigation to meet the needs of the drought. Seasonal irrigation water demand for autumn grain crops in the district.
