The Whole DAM situation (Tallest dam in US), deteriorating spillway causes lots of anxiety

This is Oroville Dam (right) and the spillway (left). Oroville Dam is the tallest dam in the United States, 50 ft taller than Hoover. It is in Northern California in a little town called Oroville (go figure). 1 hour north of Sacramento, close to Chico, CA, 2 hours south of Redding.
(http://i.imgur.com/xh6kwM7.jpg)
During these storms, the spillway was releasing 70,000 cfs of water (cubic feet a second). Large chunks of concrete began shooting off the spillway. Water started shooting into the air at this sink hole spot.
(http://i.imgur.com/7tgwYVd.jpg)
After shutting it off, they discovered this HUGE sink hole. Speculation now is that during the years of drought, the ground pulled away from the concrete. State experts are working on the cause, but we still have BIG problems.
(http://i.imgur.com/9sfVAbi.jpg)
Just some banana dudes for scale. The lake is rising during the current storms at a rate of about 130,000 cfs. It is almost near capacity. They need to release water so the dam doesn't crest or the emergency spillway be used.
(http://i.imgur.com/XMhX8Fm.png)
Overnight they did some water releasing tests. Bigger hole. Every goes into emergency meetings. Huge hole + powerful water = no easy solutions. Lake is still rising. Town is getting very scared. Many remember the evacuations during the 96-97 El Niño season.

A little side by side. Remember the dudes.

There is an emergency spillway but the State doesn't want to use it for a couple reasons. (1) They never have used it. (2) The water just spills over the the wall down the mountain. Lots of debris into the river could clog downriver smaller dams. (3) There is not controlling this. It is an open system, kind of like that little hole in your bathroom sink. The rate the water goes into the lake would be the rate the water goes over the emergency spillway. It could reach 200,000 cfs if it keeps raining.
(http://i.imgur.com/mE25a9U.jpg)
THEY HAVE A PLAN - and that plan is just to use the busted up spillway at a limited capacity. This will make the concrete problem a lot worse, but will hopefully help them beat the rain. Lots of repairs late spring and early summer. As you can see, the water is rushing down side, eroding the hillside. This is about 20,000 cfs.
(http://]http://i.imgur.com/9O07yXj.jpg)
Here it is at about 40,000 cfs. They turned it up because it rained hard. They are seriously trying not to use the emergency spillway, but they are clearing trees now because it looks like it might be used for the first time sometime Saturday.

Here is my contribution.
Thank you for following our journey. The Officials say there is no imminent threat to the public. Evacuations haven't been scheduled, but all the schools are closed (for some reason). The DAM is totally fine, for now, but our town is on edge because of the weird stuff with the spillway. It has been a total paradigm shift, all of us realizing we live downstream from a potentially huge issue.

The spillway is generally operational only in the rainy season, as a crucial flood-control outlet. Routine water deliveries flow through a power plant at the dam.

Saturday morning, helicopters flew back and forth over the dam area, as Pacific Gas and Electric crews worked to dismantle cables and electrical components from electrical towers on a hillside adjacent to the main spillway, concerned that they, too, could be dragged into the channel by the crashing flows.
Denny Boyles, a spokesman for PG&E, said the work was being done in “an abundance of caution” to minimize materials that might get sucked into the river if the land around the towers is eroded by the powerful flows.
Unlike the main spillway, which is lined in concrete, the emergency spillway dumps water onto an open hillside. DWR officials had worked feverishly in recent days to try to lower reservoir levels enough to avoid overtopping the emergency structure, concerned that the outflows would scour the hillside, dumping additional trees, mud and debris into the Feather River. Work crews spent Thursday and Friday removing some of the trees from the ravine below the emergency spillway as a contingency.
Cal Fire spokesman Mike Smith said DWR officials had laid out floating structures known as booms in the waterways to catch debris.

The dam is not at risk of failure. The spillway is a separate structure and the emergency spillway is even farther apart.

Kevin Dossey, a DWR engineer, said Friday that additional cracks had appeared in the main spillway as recently as 2013 but also were repaired. With water hitting the concrete chute at an estimated 50 mph, "spillway erosion is a natural thing," he said.
The spillway has had nearly half a century of fast moving water eroding the surface. The dam holds back nearly unmoving water. The erosion on the spillway is not related to the dam.

Good news is that it was expected to fail a couple of hours ago, and is still holding at this point. The erosion has been less than anticipated and is slowing. The water level in the reservoir is being drawn down, and they're dropping rock from helicopters to slow erosion from water spilling over the earthen spillway.

It's not the dam. The dam is fine.

Evacuations ordered below Oroville Dam after a hole is found in its emergency spillway
LA Times, Feb 12, 2017, 8:15 pm Local
Tens of thousands of residents in Northern California were ordered to immediately evacuate Sunday afternoon after erosion at the emergency spillway on the Oroville Dam threatened to flood Oroville and nearby towns below.
Officials said late Sunday that they will use bags of rocks to try to plug the hole at the head of the emergency spillway, and also will reduce the water level at Lake Oroville to alleviate stress on the spillway.
They emphasized the situation remains dangerous at the nation’s tallest dam and urged residents in communities along the Feather River to evacuate to higher ground.
The National Weather Service initially said the auxiliary spillway at the Oroville Dam was expected to fail at about 5:45 p.m., which could send an “uncontrolled release of flood waters from Lake Oroville.”

The earthen dam wasn't the problem. Looks like the problem began at te concrete spillway
Compacted earth is probably the most common type of dam there is in the USA. All of the dams around me are earthen dams with a concrete spillway and millrace. The 1 that is 100 yards from where I sit is an earthen dam first built in the 1880s and rebuilt in the 1980s.

Live updates at L.A. Times (http://www.latimes.com/local/california/la-live-updates-oroville-dam-20170212-htmlstory.html).
Latest:Feb. 13, 2017, 3:45 a.m.
"This is not a drill. Repeat this is not a drill,” the National Weather Service said Sunday, urging people living below Oroville Dam to evacuate.
More than 100,000 people were told to evacuate because of a “hazardous situation” involving the Northern California dam's emergency spillway. At one point, the NWS warned that the auxiliary spillway was expected to fail and could send an “uncontrolled release of flood waters from Lake Oroville.” However, by late Sunday night, officials said the immediate threat had passed because water had stopped washing over the emergency spillway.
• The mass evacuations cap a week of frantic efforts to prevent flooding as the reservoir behind America’s tallest dam reached capacity and its main spillway was severely damaged.
• On Saturday, water levels rose so high that an emergency spillway was used for the first time. Officials initially believed the measure worked. But Sunday afternoon, as more water from record storms flowed into Lake Oroville, officials detected a hole in the emergency spillway and eventually ordered the evacuations.
• By late Sunday, the crisis at the Oroville Dam eased somewhat, as the water level at the reservoir dropped. That halted water flow from a damaged emergency spillway that officials feared could collapse. But officials stressed that the situation is still dangerous and that evacuations should continue.
• A failure of the emergency spillway could cause huge amounts of water to flow into the Feather River, which runs through downtown Oroville, and other waterways.
• Gov. Jerry Brown issued an emergency order aimed at bolstering the state's response to the crisis. ...

So true.
But environmentalists warned about the emergency spillway more than a decade ago...
Three environmental groups - the Friends of the River, the Sierra Club and the South Yuba Citizens League - filed a motion with the federal government on Oct. 17, 2005, as part of Oroville Dam's relicensing process, urging federal officials to require that the dam's emergency spillway be armored with concrete, rather than remain as an earthen hillside.
...
The Bush administration rejected that request, however, after the state Department of Water Resources, and the water agencies that would likely have had to pay the bill for the upgrades, said they were unnecessary.
http://www.orovillemr.com/general-news/20170212/state-was-warned-about-inadequacy-of-emergency-spillway
It was the erosion of that emergency spillway that had them dumping rock via helicopter to try to decrease scour.
OTOH, the erosion was less than feared.

It doesn't matter how high they.
The problem isn't with the dam. The problem is with the concrete spillway next to the dam and the natural hillside that the dam abuts to. They could have built the dam out of concrete, steel or solid diamonds and the same thing would have happened.

They all managed to find an excuse, usually involving keeping their toys, to stay. Actions have consequences. If that dam goes, they lose their toys and maybe their lives and those of their families. But they knew better and chose to stay.

The construction of the dam is believed to have led to a quake of something like 5.7 (Richter) on a local fault, in the mid-70s.
Yes, liquifaction can occur with water and shaking. A quake would not be good right now.

The bill for repair of the spillway is likely already close to a quarter of a billion dollars.

OTOH, the erosion was less than feared.
You'd expect the soil and loose material to be stripped by the current, especially that much water. The key issue with the emergency spillway is the integrity of the underlying bedrock. I would expect that the bedrock on either end of the dam would be solid enough to withstand both the pressure of the water behind it and the flow of substantial water over it, otherwise, the reservoir would have evacuated itself long ago.

They were right to be concerned and authorities should have taken it seriously but the enviros have damaged their own credibility over the years.
However its also important to know exactly what the enviros were saying at the time. Generally when enviros speak about dams its to demand that the river be released from its shackles and allowed to run free.

And Arnie the governator was in charge of California, good to see that he took charge.
-
Yup.
They were right to be concerned and authorities should have taken it seriously but the enviros have damaged their own credibility over the years.
However its also important to know exactly what the enviros were saying at the time. Generally when enviros speak about dams its to demand that the river be released from its shackles and allowed to run free.
If the project had been approved and funded, the enviros would have sued because they suddenly discovered evidence of the endangered snarfblat of which 5 potentially exist, only live on the spillway, so building the thing would be impossible by law.
The enviros would then sue to have the dam dismantled as a safety hazzard plus legal expenses. A Cali court would have given them a win and $$$.
Eliminating every dam in the country is one of the goals of the econazis. They are not remotely concerned about public safety in this case. Or any other. I have serious doubts that they had a team of scientists or even a random construction worker 'advising them' when they determined the dam/spillway had an issue. At best, it was a 'lucky' guess.
-
While I won't take issue with the aims of ecowhacko groups trying to have dams removed, You don't exactly need a PhD in Civil Engineering to figure out that when massive quantities of water run over unprotected soil, you are going to get erosion. No "lucky guess", actually, just an unusual display of common sense.

I don't know about the dam at Oroville but a lot of dams, locks, canals etc are under the jurisdiction of the army corps of engineers. The USACE oversaw the rebuild the dam here where I live as well as one near where I grew up. In fact if I want to put in a permenant dock, I have to send plans and an application to the USACE for approval.
That said, I can't find any connection to the USACE in the case of the Oroville dam.

It requires permits from the USACE because it's affecting so-called "waters of the United States" which pretty much covers most significant water resources.

Thank you. So the Feds can set minimum requirements, but there was no reason the State Agency overseeing and paying for the work could not have decided to make the emergency spillway contain more concrete farther down the slope.

The state agencies decided it was unnecessary and fought the request. I suspect it was because of costs.

Has anyone seen discussion of this problem being partly due to attempting to maintain too high a level in the dam, given the current snow and rain conditions?
We have seen problems in Texas where it appears those responsible for flood control dams, after many years of drought, maintain too high a level in the reservoir and are unable to prevent flooding.
It is as if they retrain the operations to maintain as high a possible water level to deal with problems of water supply, then are over run by heavy rains.

They were releasing the maximum amount they felt they could without further damaging the main spillway, which had a sinkhole developing.

But when did that release start? Should it have been at slower flows a lot earlier? Or have they trained themselves to always first try to maximize lake level?

No it was not a federal project. it was built by the state of California back when they were a national leader on doing infrastructure work. Since the 80's the state has abandoned infrastructure work and even quit doing maintenance on what they had in order to spend more on welfare, environmentalism and crony projects.

They wanted the emergency spillway armored with concrete. President Bush declined their request.
Hugh Hewitt reported that the environmental groups OPPOSED concrete as a solution.
Regardless, the State of California was the negligent party. I'm no huge fan of Bush 43 (or 41 for that matter) but the reality is that the Feds had no legal right to do anything because it was owned / administrated by Mexifornia and even though it was likely not fully up to code, the state regulatory agencies had jurisdiction. It was apparently marginally compliant with federal regulations. Since we can't blame Bush, maybe we can move on to blaming DJT. (rolls eyes)
The more cost-effective solution would have been to think long-term, ignore the idiotic ecoparanoids, approve funding to line the necessary parts with concrete and just do it. Now the cost will be much, much higher than if they had just fixed the issue before it became a chaotic mess.
But of course, that is what government (especially 'Crat dominated government) does best - create chaos, needless waste, loss and destruction.
-
hah hah Not true. The environmental groups OPPOSED concrete as a solution. As usual, they were trying simply to give a lot of criticism without having any practical, constructive, cost-effective ideas for help (to effectively throw a monkey wrench into anything that was healthy for the state's economy).
The government was warned that the Oroville Dam emergency spillway was unsafe. It didn’t listen.

...In October 2005, as the Oroville Dam was going through a re-licensing process, the three groups filed a motion urging a federal regulatory agency to require state officials to armor the emergency spillway with concrete so that in the event of extreme rain and flooding, water would not freely cascade down and erode the hillside. The upgrade would have cost millions of dollars and no one wanted to foot the bill, said Ronald Stork, senior policy advocate for Friends of the River, one of the groups that filed the motion....

hah hah well, you got me. That will teach me to rely on Hugh Hewitt for information like this. However, that hardly places the Bush administration at the center of the responsibility chain. The Army Corps of Engineers tossed the ball to the state, who promptly sat on it using the legal authority of jurisdiction because they didn't want to spend the money. Maybe the state b*astards were hoping that there would be a catastrophe which would then allow federal disaster-relief funding to kick in so that the state wouldn't have to pay for it.

Reading through the aboved linked petition, these groups wanted the Emergency Spillway reclassified as an Auxiliary Spillway due to the operations maintaining a rather full reservoir. With the classification as an Auxiliary Spillway, it is no longer permitted to be designed with the expected significant damage when used. As an Auxiliary Spillway, the hillside had to be armored (concrete covered). In the petition conclusions, page 29 of 29 they stated:
ACE required regulated design-release operational-surcharge operations would divert up to this entire flow over the ungated spillway and onto the hillside to the left of the main-service spillway. In spite of believing during the 1997 New Years Day flood that it was in hours of needing to use this unarmored “spillway without a spillway,” DWR proposes to relicense Oroville Dam without constructing an auxiliary spillway to ensure such flows do not mobilize the hillside. Intervenors (in part) seek an action by the Federal Energy Regulatory Commission to require such an auxiliary spillway.
-
However, that hardly places the Bush administration at the center of the responsibility chain.
Absolutely agree.
Their argument was the state agency has chosen to operate it in such a fashion that the use of the emergency spillway is more likely (due to high water levels) than is justified by the term emergency.

Ah! Thanks very much for providing that clarifying information in the previous post. No doubt the leftist mass media will be silent on how the government pushed the matter down the road (resulting in ballooning costs to fix it) since the politicians and agencies responsible were likely all leftists.
I think I understand why Hewitt's program misled me, the environmental groups were in favor of fixing the spillway but apparently not in favor of covering the entire hillside with concrete as would have been required if it was reclassified. So I guess maybe they chickened out at the last minute when they found out that reclassification and armoring the hillside with concrete were inseparable which would explain why there was no further litigation from the groups to fight the state on the decision to leave the hillside below the dam (especially along the main channel) as it was (bare, erosion-prone soil instead of concrete).
-
I've been checking with some old timers about the two dams that were rebuilt near me in the 80s. Turns out that both earthen dams breached at the concrete spillway or millrace.
Water in the ground comes up against the impervious concrete and begins to pool and flow there. In some cases water gets behind the concrete by way of a crack. In fact, modern dams are designed to leak in a controlled and monitored manner.
The one in Horton Michigan near where I grew up actually breached twice. The first time was because the century old un-maintained earthen dam simply eroded and weakened. Trees had grown up in the dam and died further weakening it and finally a storm blew down a big willow tree perched atop the dam and took out several tons of the dam and started to flow. The USACE spent the summer rebuilding the dam and that following winter it breached beside the spillway.

It's funny...this was such a surprising revelation to me in grad school, it still stands out in my mind (I took some civil engineering classes to support my geology research, and as part of it we covered some dam design [which I didn't need!]).
But you're right, hydraulic pressure is a very important part of dam design, and lengthening the pathways the water has to seep through (so it dissipates the pressure) is an important component. In fact, without accounting for this, a dam can actually be lifted upward from the pressure difference, with water flowing under it.

Lots of mass moving at once doesn't always behave the way we would expect. Kind of like pyroclastic flows going hundreds of miles at high speed. Rock and dirt wouldn't flow as far as fast over the ground without riding on a cushion of air. Kinda like an air hockey table.

I don't know about lifting up, but water seepage can bring down a dam if the circumstances are wrong.

While not directly related, I was just looking at this indirectly related page: http://imgur.com/gallery/JMMQm
It's an important consideration in the flow of glaciers, too...a very thin layer of water can allow a glacier to flow much faster.
The earth has so many fascinating aspects. I still experience wonder and amazement.

The issue regarding possible dam structure failure seems to focus on water tunneling under the dam's base caused by erosion. As with any large structure, its stability depends upon a consistently solid base to distribute downward stress evenly along the entire structure. A small-scale failure of even a fraction of that foundation can destabilize the weight and cause catastrophic failure along the entire structure- especially since there is shifting forward force emanating from the water behind the structure. Like a crack in a curved window, even a small collapse under the foundation at the right point could destroy the structural integrity of the whole dam.

Correct, though generally, dams are designed to not distribute it evenly, but with most of the weight on the "upstream" side, where the uplift pressure is greatest. Generally, if there's a sheeted or grouted curtain under the dam, there's much less need for downforce on the downstream side than upstream.

Note how there's 150' of head at C and only 30 at K.

Exactly. The downforce isn't evenly spread. Note that the water is atop part of the dam on the upstream side, then it tails off in downforce as you go downstream from the crest.

Obama Stimulus Funds Went to California Dam in ‘Good Shape,’ But Not Oroville
Posted By Elizabeth Harrington On February 16, 2017 @ 5:00 am In Issues | No Comments
The 2009 stimulus package funded millions of dollars for safety improvements for a dam in California that was in “good shape,” but not to the Oroville Dam that is now on the verge of a spillway crisis.
Nearly 200,000 residents north of Sacramento were ordered to evacuate after fears that erosion would cause the emergency spillway to fail, which would lead to “catastrophic flooding“ from a 30-foot wall of water.
Despite more than a decade of warnings about Oroville, there is no public record of the country’s tallest dam receiving any of the more than $34 billion from the American Recovery and Reinvestment Act sent to California for infrastructure projects.

I look at the amount of erosion there, and knowing one man's erosion is another man's sediment, realize that if you or I allowed that much sediment load to enter a river we would be besieged with EPA, USFWS, ACoE, and an alphabet soup of agencies for the amount of turbidity we had caused downstream. When it is a government agency, though, Gold King Mine rules apply,,,

It's ba-a-ck! Oroville again threatening lives
Officials don't believe there would be time for evacuations if dam failed
Published: 13 hours ago
Californians who dodged a bullet only a week ago when the water from California’s Lake Oroville, a giant reservoir created by a dam 770 feet tall, was overwhelming a damaged spillway and eroding the hillside, have reason to worry again.
Not only is a massive weather system predicted to drop large amounts of precipitation over the drainage this weekend, new warnings are being issued that the entire structure could fail and people downstream wouldn’t have time to flee.
The Associated Press reported late Friday it had uncovered reports from federal regulators several years ago who insisted there should be public-warning systems, annual publicity campaigns and better detection procedures because of the threat that exists from the dam.

It kind of reminds me of the foreign film, The Wave.
