Ironically,the Three Gorges Dam was built on a fault line:

Three Gorges Dam sits on two major fault lines -- Jiuwanxi and Zigui-Badong. Geologists fear that rapid changes in water pressure when the reservoir levels are changed during flood season could activate already shaky ground and trigger an earthquake (a phenomenon known as reservoir-induced seismicity). In the seven months following the 2006 increase in water level, geologists recorded 822 tremors around the reservoir [source: Hvistendahl].

Just one of a number of potential problems.
