Earthquake lake in China being drained

The Tangjiashan “quake lake”
formed by a landslide during China’s devastating May 12th earthquake is draining slowly thanks to a sluice constructed by engineers there. Fears of the lake bursting from its earthen dam pushed authorities to find a quick and effective way to release the pressure building from the backed-up water. More than a million people living in the area were under threat of being inundated with millions of cubic meters of water.

As work crews start construction of a second drainage channel, engineers are closely watching downstream riverbanks and bridges for any sign of stress from the surging waters.

The 7.9 magnitude earthquake killed over 60,000 people and more than 17,000 are still missing.

It's terrible to look at the pictures from other countries, but it's even harder to look at the ones from America.

Unfortunately, it appears the efforts of Chinese authorities to lower the lake level are failing. Tangjiashan lake, the largest of some 30 lakes formed after last month's 7.9 earthquake, has continued to rise despite the channel opened to relieve the building water pressure. Read about it here.

Oh what a difference a day makes. Today's news reports that the lake is beginning to drain.
