At 7 o'clock on July 21, the water level of the Zhongmu Hydrological Station of the Jialu River rose to 79.40 meters, exceeding the historical highest water level of 1.71 meters, and the corresponding flow was 600 cubic meters per second. The water level and flow both ranked first since 1960; Dasha River, Communist Chaoqu and Weihe super police are 0.22m to 0.96m.

    The second is to organize the emergency evacuation of all operation and management personnel in the canal section of the Jinshui River upstream and downstream that may be affected by the dam failure flood of the Guojiazui Reservoir.
    The third is that the gates of the canal sections within the affected area of ​​the dam-break flood shall be maintained for remote dispatch and operation, and the sections outside the affected area shall be prepared for on-site manual control of communication interruption.

    The fourth is to urgently report the danger to the four provinces and cities of Beijing, Tianjin, Hebei, Henan and make preparations for water cuts and water source switching.
