WUHAN, July 18 (Xinhua) -- The Three Gorges reservoir in central China's Hubei Province has seen the second flood along the Yangtze River in 2020, the largest one arriving at the reservoir so far this year.

It is expected that this round of floods will recede after it peaked on Saturday, but a new round of floods is forecast to arrive around July 21, according to the corporation.
