Release time：2024-08-23click：5
Since June, the water inflow situation in the Hanjiang River Basin has been better than previously predicted, and the water level in the Danjiangkou Reservoir has steadily increased. The South-to-North Water Diversion Group seizes the critical window period for water supply, makes full use of flood resources during the flood season, actively monitors the water needs of provinces and cities in the water-receiving areas, actively coordinates with the Yangtze River Water Conservancy Commission to increase the water supply from the Danjiangkou Reservoir to the central main canal, and tries its best to meet water needs along the route. Give full play to the benefits of the central line project.
On June 16, the middle line project started the 2023 ecological water replenishment work. The flow rate of the first canal of Taocha Canal gradually increased from the original water delivery flow of 244 cubic meters per second to 338 cubic meters per second. Close to the design flow rate of 350 cubic meters per second. After the water transport flow increases, the middle line project will further use the surplus water to implement ecological water replenishment to nearly 20 rivers along the line, including the Sang River and the Qili River, on the basis of giving priority to meeting the production and domestic water needs of the water-receiving areas, and assisting the comprehensive management of groundwater overexploitation and ecological protection in North China. Environmental recovery.
It is understood that since the beginning of summer, due to high temperature weather, the demand for water along the water receiving areas has increased significantly and is more urgent. Under the current optimistic situation of water supply, after further communication and coordination, the flow rate of the first inlet of Taocha Canal increased to the design flow rate of 350 cubic meters per second on July 1, and further increased to 380 cubic meters per second on July 6. .
