They Chinese media have reported that the water level in the dam rose to 739.52 metres above sea level at 4 a.m. GMT today. This is 48 centimetres from the bottom of the channel.

I hope someone has some video cameras running on this thing. When it goes, it should be epic!
The time I have mentioned is the time of Beijing. Water level at 15:30 was 739.64m, at 17:00 was 739.70m and at 18:00 was 739.74m. (http://news.sohu.com/20080606/n257337366.shtml)
Water level incresed to 739.82m at 20:00 Beijing time. Probably, the lake will overtop in next 4 to 5 hours.
For the last 6 hours, the water incoming to the lake is about 72 units per second.
The level is 739.87m at 21 Beijing time.
Dear All:at 10:40 Bejing time, the water level is 739.92, only 8 cm. There are still work to increase the channel capacity right now.
Xinhua:Water level of China’s main quake lake Tangjiashan climbed to the critical point of 740 meters on a sluice channel at 0:00 a.m. Saturday, but the long-awaited drainage hasn’t started yet.
