Water levels at China’s giant Three Gorges Dam on the Yangtze river are inching closer to their maximum after torrential rains raised inflows to a record high, official data showed on Friday. Al Jazeera reports that with 75,000 cubic metres per second of water flowing in from the Yangtze River on Thursday, the reservoir’s depth had reached 165.6 metres by Friday morning, up more than two metres overnight and almost 20 metres higher than the official warning level. Authorities raised the discharge volume to a record 48,800 cubic metres per second on Thursday to try and lower water levels, and they might have to increase it again to avoid the possibility of a dangerous overflow which could lead to the entire dam wall collapsing.
