China News Service, Nanchang, August 14 (Wu Pengquan) Jiangxi Provincial Flood Control and Drought Relief Headquarters reported on the 14th that as of 11 o'clock that day, a total of 213 flood dikes had entered the Yangtze River and Poyang Lake areas.
Since the beginning of July, due to the combined effects of heavy rainfall and the inflow of water from the upper reaches of the Yangtze River, a super-historical flood in the Poyang Lake Basin has occurred in Jiangxi, a province in the middle and lower reaches of the Yangtze River.
Facing the catastrophic flood of Poyang Lake, Jiangxi started to use single-return dike for flood diversion in an orderly manner. The Jiangxi Provincial Flood Control and Drought Relief Headquarters previously issued relevant notices, requiring all single-return dikes in the Poyang Lake area to actively open gates to clear the weirs and store the floodwater. Before flood diversion, people who may appear in the dikes must be transferred in advance.
Single retreat dike refers to "low-water cultivation and high-water flood storage". Flood intake and drainage facilities are built on the dike, and floodwater is stored when the flood level is above the flood level, and the water level of the outer river (lake) is lower than the flood level. Agricultural production can still be carried out at that time.
According to data disclosed by the Jiangxi Provincial Flood Control and Drought Relief Headquarters, as of 11:00 on August 14, a total of 213 flood dikes have entered the Yangtze River and Poyang Lake areas. Among them, there are 185 single-return dikes in the lake area, 17 single-return dikes on the Yangtze River, and 11 other dikes.
It is worth noting that 32 of Jiangxi's levees have entered the Hongwei dyke, 29 of which are single-return dykes in the lake area and 3 are other dykes. Fifty-six dikes have been drained, all of which are single-return dikes in the lake area.

The latest data shows that at 16:00 on August 14, there were 8 super-alert stations in Jiangxi province. The water level at Xingzi Station, the iconic hydrological station of Poyang Lake, was 19.66 meters, and the over-alert water level was 0.66 meters, down 0.08 meters from 16:00 on the 13th; the water level at Poyang Lake Hukou Station was 19.58 meters, and the over-alert water level was 0.08 meters, down 0.09 meters from 16:00 on the 13th; The water level of Jiujiang Station on the Yangtze River was 20.11 meters, and the super-warning water level was 0.11 meters, which was 0.09 meters lower than that at 16:00 on the 13th.
Based on the real-time rainfall and the analysis of the rainfall forecast in the middle and lower reaches of the Yangtze River in the next three days, the daily retreat at Poyang Lake Xingzi Station is about 0.10 meters, the daily retreat at Hukou Station is about 0.10 meters, and the Jiujiang Station on the Yangtze River is expected to return 0.10. About meters.
The Jiangxi Provincial Flood Control and Drought Relief Headquarters reminded that it is necessary to focus on the flood control safety of the dikes in the Poyang Lake area and Weilu area, and strengthen inspections. (Finish)
