China News Service, July 12 (Xinhua) According to the "China Water Conservancy" WeChat public account, due to the continued strong rainfall, the middle and lower reaches of the Yangtze River mainstream under the supervision of the river section and Dongting Lake, Poyang Lake across the water level across the police, the Ministry of Water Resources on the 12th The level Ⅲ emergency response of disaster prevention was upgraded to level Ⅱ. The Yangtze River Water Resources Commission and the Taihu Basin Administration initiated the level Ⅱ emergency response to strengthen the defense work.
Affected by the continuous heavy rainfall, the lower reaches of the Yangtze River main stream and the water level of the Dongting Lake and Poyang Lake across the board were super-alarmed. Among them, the water level of Dongting Lake was slightly exceeded. The water level of Dongting Lake Chenglingji Station was 5:30 on July 12 at 34.58 meters. (2.08 meters above the warning water level and 0.03 meters above the guaranteed water level); the peak water level at 12 o'clock at the Lianhuatang Station in the middle stream is 34.34 meters (1.84 meters above the warning water level and 0.06 meters below the guaranteed water level). At 18:00 on July 12, the middle and lower reaches of the Yangtze River and the water levels of the two lakes exceeded 0.55 to 2.96 meters. At present, Hongfeng is passing through the Luoshan River section, the water level of the lake mouth is 22.46 meters (0.04 meters below the guaranteed water level); the average water level of Taihu Lake is 4.45 meters, exceeding Police 0.65 meters.
Based on current water and rain conditions and recent precipitation forecasts, it is expected that the water level below the Hankou and Poyang Lake in the main stream of the middle and lower reaches of the Yangtze River will continue to rise, and Poyang Lake will exceed the guaranteed water level; Taihu Lake will continue to rise and may exceed the guaranteed water level; the upper Yangtze River and the Huaihe River There will be a significant flooding process in the water system. The water level of the upper mainstream of the Huaihe River may be close to the alert. The Shiguan River and the Pihe River in the Huainan Mountain Area may exceed the alarm. Some small and medium-sized rivers in the rainstorm areas of Sichuan, Chongqing, Hubei, Henan, Anhui, Jiangsu, and Zhejiang Provinces may be A major flood occurred.
E Jingping, deputy commander-in-chief of the State General Defense Department and Minister of Water Resources, led a working group to inspect and guide the flood prevention work in Jiangxi on the 12th. On the 12th, Ye Jianchun, deputy minister of water resources, chaired the meeting and deployed the current flood control work of the Yangtze River, Taihu Lake, and Huaihe River. It required rolling monitoring and forecasting, carefully coordinated and scientifically dispatched water projects such as the Three Gorges Reservoir, and worked hard to reduce disaster losses and disaster risks; the Yellow River and Haihe River , Songliao and other river basins are more difficult to defend, and we must base on adverse conditions and implement the response measures in advance.
The Ministry of Water Resources at 11 o'clock on the 12th raised the level Ⅲ emergency response to flood and drought disaster prevention to level Ⅱ. The Yangtze River Water Resources Commission and the Taihu Basin Administration initiated the level Ⅱ emergency response to strengthen the following defense work.
One is to strengthen monitoring, forecasting and early warning. A special class for forecasting and forecasting water and rain conditions was organized to increase the frequency of rainfall forecasting in the Yangtze River, Taihu and Huaihe river basins, strengthened consultations between meteorological and hydrological departments, and timely report the forecast results to the Ministry of Emergency Affairs to win time for flood relief.
The second is to finely coordinate the water project. On July 11, the Ministry of Water Resources and the Yangtze River Water Resources Commission dispatched the outflow of the Three Gorges Reservoir to 19,000 cubic meters per second, as far as possible to control the water level of Lianhuatang Station not to exceed the guaranteed water level, and reduce the flood control pressure in the middle and lower reaches; dispatch the outflow of Danjiangkou Reservoir Reduced from 1500 cubic meters per second to 500 cubic meters per second, creating conditions for the Changhu flood discharge in Hubei Province, while reducing the pressure on Wuhan's flood control. The next step will be to consider the upstream and downstream flood control situation and the project's own safety and other factors based on the forecast and forecast results, and scientifically and finely dispatch the key water projects such as the Three Gorges, Danjiangkou, Taipu Gate, Wangting Water Control Project, etc., to reduce the pressure on the flood control of the middle and lower reaches of the Yangtze River and reduce it as much as possible. Water level of Taihu Lake and surrounding river networks. According to the forecast of the rain water situation, the water works of the Huaihe River Basin should be dispatched well, and the conditional reservoirs should be released in advance.
The third is to strengthen the embankment defense. Several notices required the relevant provinces in the Yangtze River and Taihu Basin to strictly implement the defensive responsibilities of the embankment section, and implemented the defensive measures for the embankment inspection. The Ministry of Water Resources sent four secret visits to supervise the secret visits. If problems were found, they will be fed back to the localities in a timely manner to urge local rectification to be implemented. To ensure the safety of key embankments and important protection targets.
The fourth is to prepare for the defense of floods in northern rivers. The Huaihe, Yellow River, Haihe, Songliao and other river basins have more flood control difficulties, more difficult defenses, and higher risks. Based on the prediction and forecast opinions, the Ministry of Water Resources has combed and analyzed the shortcomings of the flood control of the northern rivers such as the Yellow River, Huaihe River, and Haihe River. The key work arrangements for the defense of the northern rivers such as the Yellow River, Huaihe River, Haihe River, and Liaohe River were proposed. The next step will be to urge the localities to implement various defense measures and prepare for flood response.
On the 11th, the Ministry of Water Resources notified the Ministry of Emergency Affairs of the super-alarm and over-protection of the main stream of the middle and lower reaches of the Yangtze River, Dongting Lake, Poyang Lake, the middle and lower reaches of the Gan River, Xiushui, Xinjiang, Qingyi River, Shuiyang River and Taihu Lake and Liujiang River. Prepare for flood relief.
