According to reports, since each cascade reservoir returns to its natural state during the flood, it is re-stored at the end of the flood. As a result, the increased incoming water upstream of Wujiang is basically digested by each cascade reservoir, and the second flood peak originally predicted to appear was basically flattened. Shaoguan Hydrological Bureau predicts that the water level in the urban area and the downstream Beijiang River section will continue to fall slowly, but will remain above the alert state for more than one day.
