One hundred million cubic meters.
According to the relevant person in charge of the Yangtze River Water Conservancy Commission, the upper reaches of the Yangtze River and the Three Gorges area have recently encountered heavy rainfall. As a result, the inflow of the Three Gorges Reservoir rose to 50000 cubic meters per second at 10:00 on the 17th. form. At 8:00 on the 18th, there was a peak flow of 61,000 cubic meters per second in the Three Gorges Reservoir, and the flow out of the reservoir gradually increased.

At 14:00 on the 19th, the inflow of the Three Gorges Reservoir has retreated to 53,000 cubic meters per second, the outflow of the reservoir has increased to 41,000 cubic meters per second, and the reservoir water level has risen to 163.88 meters, exceeding the 145-meter flood limit water level of 18.88 meters. Within 78 hours, the accumulated flood storage capacity of the Three Gorges Reservoir was about 6 billion cubic meters, and it is still in the flood control phase.
At present, "Yangtze River Flood No. 2 in 2020" is evolving towards the middle and lower reaches. After superimposing the inflow in the middle reaches, the water level in the section from Chenglingji to Hankou River and Dongting Lake in the main stream of the middle and lower reaches of the Yangtze River will rise. With an increase of about 0.9 meters, the water level in the section below the Jiujiang River and the Poyang Lake area fluctuates or recedes, and the above areas will remain above the warning water level for a long time.
In addition, due to the influence of heavy rainfall, the Chuhe and Chaohu water systems have also experienced major water increases, and many hydrological sites have exceeded historical water levels.
In view of the current water situation, the Hydrological Bureau of the Yangtze River Water Resources Commission issued a blue flood warning for the Shashi section of the middle reaches of the Yangtze River at 12 o'clock on the 19th, upgraded an orange flood warning for the Chuhe River, and continued to issue the Yangtze River section below Chenglingji, Dongting Lake, and Orange warning for floods in Poyang Lake District and Shuiyang River, and yellow warning for floods in the Shigu River section of the Jinsha River, and the relevant units and the public along the route are cautioned.
