Water is now below the emergency spillway. Normal spillway erosion seems to be stable, no more silt in the water so must be down to bed rock now

Now the tyler island levy is in serious threat of breaking

From what I can tell they are trying to walk the fine line between too much release of water and damaging downstream, and too little and not having the capacity ready for the coming storm.

I'm in Folsom (Sacramento area) supposedly the emergency spillway was predicted to fail at 6pm Sunday and mandatory evacuations started. Nothing for the Sacramento area. Spillway(s) are badly eroding but haven't failed completely yet.

Thay are now preparing to drop large rocks and bolders with helicopters on the eroded areas to by more time.

That is the last I heard also. I was watching a live feed earlier today. Crazy amount of water being let loose down the spillway.

they better get their ass's to work and start throwing some big rocks in the eroded areas so they can let water out after the storm to come!

So now there is talk that in 2007 this issue with the emergency spillway was not going to work as planed with all of the dirt at the base and engineers warning about erosion.

Politicians at the time didn't want to spend anything to fix it when the water was low.

Those pictures are of the emergency spillway which is nothing more than a dirt hill and was only meant to be used in extreme circumstances... The normal spillway developed the large hole in the middle of the concrete that you see in the pics. 2 different spillways, same dam.

Ahhhh. Ok. So basically they have it wide open and the emergency spill way is in use and it still isn't enough.

Mandatory evacuations have been lifted.

Reports are now out that this problem has been known about since at least 2005. Local government, California governor and the bush administration didn't want to spend any money to correct it. Seems some are out for blood now looking for the ones responsible.

It is also raising the question of how many other dams or large structures have major issues the have been ignored by our government and responsible parties.

A full scale investigation will likely start soon

This is happening a lot. Nothing put back into the infrastructure to prevent future problems until its to late. Like this scenario.
Look at the city of Los Angeles. 75-100 year old water mains breaking. They patch them until it breaks some where else.
