Mass Evacuation in CA as fate of Oroville dam uncertain

http://ift.tt/2l20JAL

188,000 people evacuate downstream of the dam on Sunday. There is damage to the main spillway and so water is over flowing the emergency spillway for the first time in the dams history. The worry is that the water will erode the hillside and could possibly lead to a partial or full failure.

Dams can be dangerous. In 1975 a dam failure in China killed 171,000

The Mosul dam in Iraq needs constant maintenance and could also fail.
