Looks like none of Obama's stimulus money didn't get spent here over the past 8 years.

That went to Iran and other Muslim countries.

Crews using helicopters yesterday to move large bags of rocks into Oroville emergency dam spillway.
It wouldn't been a lot easier to fix when the lake was empty in 2013

First of all the dam is not failing. An emergency spillway designed in the 60's, with no concrete apron to lead any potential floodwater away from the spillway, suffered severe erosion during last weekend's release over the spillway. So they are lowering the level of the lake to take pressure off the emergency spillway and now are dumping tons of rock, new concrete and sand into the eroded areas of the land below the emergency spillway. So there was a study done that suggested a concrete apron would help reduce any potential erosion in the event the emergency spillway was ever needed. That never got done and now the spillway was used and it suffered.
Hopefully, this work they are doing now can be helpful with the rain expected starting Thursday and the thought is that if they lower the lake enough it may not reach the level of the emergency spillway again.
The damaged main spillway is, to me, the more serious situation that could cost hundreds of millions to fix or rebuild this summer.
By the way, I live about 50 miles downstream and as of now we are in the clear.
That's part of the problem. The emergency spillway was never used until last weekend so they didn't know how it would act when it was actually used. So in 2013 they didn't know it was going to cause the severe erosion. I know engineers that are on this job as we speak.
I understand exactly what your saying considering I'm a civil engineer in the heavy/highway construction business, but where is the so-called "hole"?
I'm not a civil engineer, but I could have told you using the emergency spillway would cause severe erosion

That picture was taken last Tuesday when this all started. That "hole" is now a gigantic torn apart spillway with complete failure of the lower part of the structure.There is a hole in the main spillway.....
Climate disruption, textbook definition. We are just seeing the iceberg on the horizon.
So the good folks in Cali in charge of this dam and its maintenance ignored both repair recommendations and the clear and present danger of climate warming/change/disruption. Awesome.
I have no ******* clue what they plan to do if they get more rain.....
