A major maintenance project began on 15 October on the No.3 shiplock of Gezhouba Dam, 38km downstream of the Three Gorges Dam. Such work happens once every six years.

Between 22 November and 5 February 2010, the operation of the No.3 shiplock will be suspended. Maintenance will be carried out on a number of items such as machinery and water works, and is scheduled to be completed by the end of May 2010.
