The water level of the Three Gorges Reservoir drops to 149.40 meters as of as of 14: 00 on Wednesday. More than 19.6 billion cubic meters of water, about 90 percent of its capacity, has been released to brace for the flood season. (Photos: China News Service)

Rainfall in Dongting Lake region and Poyang Lake region since May led to the continuous raising of the water level in the middle and lower reaches of the Yangtze River. The water level in cities like Wuhan is now on alert. The reservoir adjusts its water level according to the flood situation and ecology of the middle and lower reaches of the Yangtze River.
