Sayano--Shushenskaya Dam: Help us to prevent great disaster in Siberia

Russia's government is doing nothing to prevent a disaster and is putting 1.5 million people, as well as the environment of the Arctic, in danger. The biggest hydro power station in Russia, located in Siberia, had a major accident in August 17 (1 2 video footage) , 2009 and took the lives of 75 people who worked there. This accident completely damaged the way the power station function.
DAM COULD COLLAPSE IN THE CURRENT FLOOD:

Media and authorities in Russia are hiding the fact that the current flood of the river Enisey is going to be three times higher then normal m3/s. At the moment the dam can only pass water in three ways: 1) Regular spillway, (1)
2) spillway that's recently completed (1 2 3)
3) power generators that are also presently in rush development (1 2).

Regular spillway could pass not more then 5000 m3/s without being destroyed.
(Images of spillway destruction in 1986. 1 2 3 4)
Another water spillway completed but never tested.
This new spillway will allow 2000 m3/s to flow through.
The two power generators that are also being developed will allow 700 m3/s to pass through.
In total, the spillways in development together with the two new generators will only handle 7700 m3/s of water to flow through judged against the forecasted spring flood forecasted at a minimum of 15,000 m3/s.

The Russian government and media have concealed from the public the fact that in 1986 the spring flood was 15,000-20,000 m3/s. This year flood is higher and dam collapse is inevitable.

I just read a very interesting article in Power Magazine about the causes of the turbine disaster and everything points to a severe lack of maintenance, ignoring stress cracks in the machinery base and cycling the turbine to follow peak power needs thus opperating it in a high vibration mode that caused its failure. I hope the spillway can handle the spring floods and the water doesn't overtop the dam. Hopefully the dam can handle the dynamic flood stress.
