China News Agency, Wuhan, July 11 (Reporter Xu Jinbo) A reporter learned from the Yangtze River Water Conservancy Commission on the 11th that in order to reduce the pressure on flood control in the middle and lower reaches of the Yangtze River, the Three Gorges Reservoir has recently continued to reduce the discharge flow. As of the 11th, the outflow from the Three Gorges has been reduced to 19,000 cubic meters per second.

According to the relevant person in charge of the Yangtze River Water Resources Commission, the northern part of the water systems of the Jialing River, Dongting Lake and Poyang Lake experienced heavy rain on the 10th. It is estimated that there will be heavy rains on the 11th to the north of the main stream of the upper Yangtze River, the Wujiang River, and the middle and lower reaches of the Yangtze River; from the 12th to the 13th, the rainfall intensity will slightly weaken, and there will be moderate to heavy rain near the main stream of the upper and lower reaches of the Yangtze River; 14 From the 17th to the 17th, due to the influence of cold air, the rainfall intensity was strengthened again, and there were heavy rains in the Wujiang and the Three Gorges section, northwest of the Dongting Lake water system, and near the main stream of the middle and lower reaches of the Yangtze River.
Affected by the continuous heavy rainfall, there are 7 stations exceeding the historical water level (6 stations are located in the Poyang Lake area and Weilu), 10 stations exceeding the guaranteed water level, and 102 stations exceeding the warning water level, mainly from 8:00 on the 10th to 8:00 on the 11th, mainly It is distributed in the main stream of the middle and lower reaches of the Yangtze River, the northeast Hubei water system, the Dongting Lake, the Poyang Lake area and the water system, the tributaries of the lower Yangtze River, Qingyi River, Shuiyang River, Chaohu and other places.
At present, the water level in the lower reaches of the Yangtze River in the middle and lower reaches of the Yangtze River, the Qili Station in Dongting Lake, and the Hukou Station in Poyang Lake continues to rise, and the river sections near Hukou have the fastest growth. At 14:00 on the 11th, the water level of the lotus pond was 34.24 meters, only 0.16 meters away from the guaranteed water level; the water level of Hankou Station was 28.36 meters, with a daily increase of 0.32 meters, ranking sixth in the highest water level in history; the water level of Hukou Station was 22.20 meters, with a daily increase of 0.5 meters , Only 0.30 meters away from the guaranteed water level, ranking second in the highest water level in history.
It is expected that in the next few days, the river section near Chenglingji, the main stream of the middle and lower reaches of the Yangtze River, will still have an increase of about 0.2 meters. The water level of Lianhuatang Station will be close to the guaranteed water level. The section of Hankou to Datong River will still have an increase of about 1 meter. Jiujiang to Hukou River The segment will exceed the guaranteed water level.
The Hydrology Bureau of the Yangtze River Water Conservancy Commission continued to issue red warnings for floods in the middle and lower reaches of the Yangtze River main stream from the Jiujiang to Hukou and Poyang Lake areas. The relevant units and the public along the middle and lower reaches of the Yangtze River, Dongting Lake area, Poyang Lake area, Shuiyang River and other places should pay attention to the prevention.
With the cooperation of the reservoirs in the upper reaches of the Yangtze River, the daily outflow of the Three Gorges Reservoir has gradually decreased from 35,000 cubic meters per second on the 7th to 19,000 cubic meters per second on the 11th. At 14:00 on the 11th, the water level of the Three Gorges Reservoir reached 150.25 meters, and the inflow and outflow were 23,000 cubic meters per second and 18,900 cubic meters per second respectively, which was again reduced from the 24,800 cubic meters per second outflow on the 10th.
