I'm watching coverage on KRCR and KDRA right now.
Can't help but notice a seeming lack of diversity among the emergency responders.
Well, we still have Fukushima.
No. The issue is the emergency spillway to the left of the broken regular spillway. It's hard to detect, since it just appears as a large area of shrubs and foliage. If the top goes, the top 30 feet of the entire lake will cascade into the river below. That hasn't happened as yet, but officials consider the risk high enough to order the evacuation.
Inspection / maintenance engineering operation—toast.
These are the fruits of a Democrat run State. A disaster. Immense prayers for all these people. Lord protect them all.
“Department of Water Resources spokesman Kevin Dossey told the Sacramento Bee the emergency spillway was rated to handle 250,000 cubic feet per second, but it began to show weakness Sunday at a small fraction of that. Flows through the spillway peaked at 12,600 cubic feet per second at 1 a.m. Sunday and were down to 8,000 cubic feet per second by midday.”
No an engineer here, but it sounds like they now do not have the design controls that were built into the dam.
But, has it been maintained and upgraded in that time?
“The press conference right now sounds like that spillway failure is not imminent. “
There is a hole under the spillway.
It will fail, if not in the next hour, in the next 12-24 hours.
The Russians hacked the dam?
.
The material under the emergency spillway is soft limestone.
It will go slowly, and leave the weir high and dry.
Bigger danger is damage to the head gates of the main spillway from that erosion.
Yes, but the dam was almost finished by the time he was elected governor.
In fact, it was topped out in the very year he became governor, 1967.
How about driving out at least part way so you get past key bottlenecks? Wait there for several hours - avoid the panicked hordes?
It’s going to be like the freeways of LA, a parking lot.”
Bet a lot of them don’t have a tank full of gas, extra food or any cash money. We live on the Gulf and ever since Hurricane Ike we always have bug out bags ready to go, extra cash and never let the gas tank get below half full. Just a habit we developed.
Hopefully the next 12-24 hours allows everyone in path of the danger to get out.
Whether or not their town is spared is unknown, but at least lives will be spared.
This dam was apparently dedicated when Reagan was Governor. Expect his name to be dragged through the mud.
The problem, at least according to statements from a TV helicopter pilot who was streaming live about 1 hour ago, was that water was running over the area at the end of the emergency spillway and eroding soil there, and that erosion could lead to a failure of the emergency spillway.
They ran out of daylight, but there is video showing the problem area and the traffic backups of people trying to escape Here
Yes, same one.
Where do you see a reference to a “hole under the spillway”?
If you’re referring to the hole in the concrete-lined spillway, that hole does not appear to have expanded upstream since yesterday.
“weakness” evident of 5% of the design flow. Usually with good design margins, things will work at 1.5X to 2X of rated capacity. Here we have potential failure at 5% of rated capacity. That is very odd.
It’s wonderful that we are building a useless high-speed choo-choo and ignoring our basic water infrastructure. State heads better roll over this (starting with moonbeam) even if the situation gets no worse.
