California lake Oroville spillway damage explained

[timmy]

Green... Oroville Dam, no damage, working properly. Yellow.. Main Spillway, Damaged, but still working Red.. Emergency Spillway, highly damaged and most like going to fail if used again.

Main Spillway. This is the cause of all the problems. In the image, the water flow has been stopped and the lake levels are rising.

[timmy]

The people in charge knew if they reopened the gates more damage would occur. So they kept them closed and let the water level rise till it reached the Emergency Spillway.

[timmy]

So here water is flowing over the Emergency Spillway. It eroded quickly and was the reason for the evacuation order was give.

[timmy]

The people in charge said. IT. Open the gates. The main spillway got ripped apart in no time but only down stream of the hole shown earlier.

Here you can see the damage that happen in a short time to the Emergency spillway.

[timmy]

Everyone better hope the Main Spillway holds together. Its very possible the hole will move up the spillway. But it seems to be stable for now. If the hole / damaged area starts moving upward and reaches the gates, its GAME OVER. Now they know this, so if it does start to move they will stop the flow of water and attempt to quickly repair it. But the lake will start to fill again and they will not have much time before they must open it again because the Emergency Spillway clearly will not hold up. If the hole does not move upstream, everything will be fine. But its a few more months before the rains stop. Lets hope for the best.
