Responding To Drought &Nbsp; China Has Substantially Increased The Discharge Capacity Of The Three Gorges Reservoir.

From 20 to the beginning of next month, China will take Discharge capacity of Three Gorges Reservoir Increase to more than 10 thousand cubic meters per second to cope with the drought in the middle and lower reaches of the Yangtze River.

The national defense general said that from 20 to 24 days, the Three Gorges reservoir will be discharged at the level of 10000 cubic meters per second on a daily basis. This volume is higher than 3000 cubic meters per second.

From May 25th to June 10th, the daily discharge of the Three Gorges reservoir will increase to 11000 to 12000 cubic meters per second, and further raise the water level of the middle and lower reaches of the Yangtze River to meet the needs of drought resistance in the two provinces of Hubei and Hunan, and alleviate the urban and rural water supply along the Yangtze River. irrigation diversion And shipping pressure to ensure water use and shipping safety in the middle and lower reaches of the Yangtze River.

The national defense general said that the rainfall in the middle and lower reaches of the Yangtze River has been reduced by 4 to 6 percent over the same period of the year, the most common period since 1961. Since May, precipitation has increased slightly compared with the previous period. However, the precipitation in some parts of Hubei, Hunan, Jiangxi, Anhui, Jiangsu and other provinces is still 2 to 4 less than that of many years.

By this effect, the amount of water in the main rivers in the middle and lower reaches of the Yangtze River is 1 to 7 less than that in the same period of years. The water level of the main control stations in the Dongting Lake water system and Poyang Lake water system is 0.43 to 4.20 meters lower than that in the same period of the same period. The continuous lowering of river water level not only affects the normal operation of the self flow irrigation facilities along the line, but also causes insufficient pumping facilities for urban water supply along the line, and agricultural irrigation and urban and rural water supply are affected. Among them, the two provinces in Hubei and Hunan are relatively prominent.

In order to fight drought, China opened the sluice and discharged water at the Three Gorges reservoir. The national defense general said that this year, the Three Gorges reservoir has accumulated 17 billion cubic meters of water to the middle and lower reaches of the Yangtze River, and the water level of the middle and lower reaches of the Yangtze River has been picked up. Dongting Lake, Poyang Lake As the water level continues to rise, the water level of the Xiangjiang and Ganjiang rivers has increased considerably, which has effectively protected the water supply of the cities along the Yangtze River.
