The largest flood peak since 1981 smoothly passed by Three Gorges, and the Three Gorges Reservoir successfully completed its firs "big advantage". At 8 o'clock in this morning, our reporter saw that the water level in Three Gorges Reservoir had reached 159.86 meters after the Yangtze No.4 flood peak. It was predict that the water level will continuously increase, reach 163 meters.

At 20 o'clock in last night, the largest flood peak in this summer – Yangtze No.4 reached Three Gorges Reservoir. The incoming flow rate reached 71,200 cubic meters per second, and the water level in the reservoir increased to 158.04 meters. Three Gorges Dam opened eight discharge holes to discharge the flood with 43000 cubic meters per second. With the effective interception of Three Gorges Reservoir, the flow rate of flood peak was decreased to 28100 cubic meters per second, about 40 percents, which effectively alleviate the flood control pressure in downstream of the Yangtze River. It was introduced by Zhang Zhitong that "the flood control and adjustment effect of the Three Gorges Reservoir is very obvious". Until 22 o'clock in July 24, the incoming flow rate of Three Gorges Reservoir has go back to 70800 cubic meter, and the water level in Three Gorges Reservoir was 158.33 meters.

In this afternoon, our reporter went to the most dangerous part of the Yangtze River – Jinjiang River section. In the past, there were many flood control teams on the Jinjiang River dam once there were big flood peak. Although flood in this year is very strong, with the help of Three Gorges Reservoir, the water level in Jinjiang River section did not go beyond the warning water level. The water level in Guanyinji is 42.68 meters after the Yangtze No.4 flood peak, 0.32 meters to the warming water level. While in 1998, the water level at there is 45.22 meters. It is predicted by Hydrological Department that the water level in Jinjiang River will not pass by the warming water level in coming several days.

It was introduced by Wei Shanzhong that the Three Gorges Reservoir dammed up over tens billions flood, ensured the safe in middle and down stream of the Yangtze River. Wei Shanzhong said that the general principal of Yangtze flood control and adjustment is "giving attention to storage and discharging, mainly focus on discharging", paying attention to the both banks and coordinating the upstream, midstream and downstream".
