I know this is an old thread but I just picked up some news via the BBC and I think I will post it here rather than on Breaking News as it seems
better placed here. It looks like we/they will know more about the stress/tolerances of the site/structure soon enough...
"China's Three Gorges dam faces flood test" 20 July 2010, BBClink to article which

"Dr Cao Guangjing, head of China Three Gorges Corporation, says there's "no problem" with the dam
The Three Gorges dam on China's longest river, the Yangtze, is standing up to its biggest flood control test since completion last year, officials
Floodwaters in the giant reservoir rose 4m (13ft) overnight, and are now just 20m below the dam's maximum capacity.
The authorities are using the dam to limit the amount of water flowing further downstream to try to minimise the impact of devastating floods.
Beijing cited flood control as a main reason for the $27.2bn (£16.7bn) dam.
Hundreds of people have died in central and southern China in the country's worst floods in more than a decade.
The Three Gorges dam, the largest in the world, was a controversial project as it forced the relocation of 1.4 million people. It is situated in Hubei
The flow of the water overnight was the fastest ever recorded, at 70,000 cubic metres per second.
Dr Cao Guangjing, head of China Three Gorges Corporation, told the BBC that 40,000 cubic metres/second were released, with 30,000 cubic metres/second
of water held back in the reservoir.
"Without the Three Gorges this kind of discharge would bring disaster to the downstream areas," he said. "
Looks like they have some confidence in it's structural integrity, or do they have no other options...probably both?
