China says flood waters at the Three Gorges Dam will peak within the next 24 hours, after torrential rain further up the Yangtze river over the weekend.
The country suffers monsoon-type rains every year but this year's rainfall has been the heaviest in more than a decade.
Authorities say that disasters caused by the bad weather in recent weeks have already left more than 1,250 people dead or missing.
