If you want to see the Three Gorges (the Qutang, Wuxia and the Xiling) before they are lost for ever – as a result of the controversial dam project on the Yangtze, you should aim to see them before November 1st 2002. After this date, there will be a diversion around the Three Gorges and the Yangtze will not be navigable until after the flooding has taken place in 2003.
