BC landslide: Fears of giant water gush in Chilcotin River rise
HTML-код
- Опубликовано: 8 сен 2024
- In the Caribou region of B.C. - about 600km northeast of Vancouver - there are hopes tonight that a serious flooding disaster may be averted.
On Tuesday night, a giant landslide came down, blocking the Chilcotin River.
That river flows into the much larger Fraser River and when the blockage gives way, a rush of water could ensue.
Catherine Urquhart has the latest.

They're saying it could cause an ecological disaster, but this is nature doing natural things. These types of things have happened for hundreds of years and nature always recovers. It's man that seems to struggle to "survive".
Thank you for stating that. It was my first thought too.
living beside a river
*thousands of years. Agreed.
The breach could start with what’s called “piping”, small underground veins of water finding their way through to the other side. The soil is mostly sandy and porous
I don't understand how they think it's going to crest the top and then that's it. I'm no expert but I'm almost 100% positive that once the lake behind the slide reaches the top it will just be a matter of time before the water fully saturates the slide debri and then undermines it before it all let's go. They should be trying to clear a path to let water through now before there's 10 billion liters backed up. Good thing to know our leaders will do nothing just like in Jasper.
Doubt it. It’s too long and high. It will come over the top and when it does it will be carving out a new river through the slide area..🧐
Yeah, basically that dirt dam could liquefy from beneath and really come down like muddy pudding. It's all loose material, so even if it "just" overtops, it will still wash out in a really short period of time.
I'm dumbfounded why they are seemingly trying to play it down...
@@joeskill4663 I've studied geology and "long and high" has nothing to do with it. It's all loose material and I guarantee the water is already working it's way through and under that natural dam, especially as the temporary lake gets bigger and deeper and the water pressure down near the river bed is drastically increasing.
@@MrEricmopar Certainly this video isn't "playing it down"!
No panic; the river will cut a new path through the landslide. Stuff like this has been happening for millions of years.
yes but when it does there will be rapid erosion of the blockage and a sudden torrent of water and debris going down river. Thats what they are worried about. Rapid flooding and debris going down river.
Bro doesn't know about landslide based flash flooding
@@avroarchitect1793 We shall see. I base my assumption on the length of the slide and the fact that the river is already creeping over the top of it. Bro!
@@CypherJj4457 Yes I do.
You're no fun.
Once in a lifetime natural phenomena we all get to witness and celebrate as a community 😀
Over 9 million cubic meters of mountain stuck in mud. I'd be surprised if it burst/gave way. I'm betting on a new lake being born and the overflow finding it's way back down the rivers path.
new lake wont last long. That's all dirt, not bedrock. Will erode quickly.
@@thems_the_brakes great point
Time to invest in lake side real estate, with 100% water views

@@johngreydanus2033 Previous investments with river views did not work out that well
Thank you for sharing this update. Previous landslides in Chilcotin such as the 1964 event didn’t result in catastrophic breach but they gradually eroded a channel from the top down.
They need big disasters to pump up the news.
Yes, just reading about that, the news like to terrorize people.
From what I gather, this is basically a bunch of mud and small particle sediment.
If you've ever watched vids when people intentionally breach on the beach, it goes from a trickle to scary very quickly.
Although its 1KM long...It seems this could happen here as well.
Which is exactly what will happen here. Its not going to suddenly fail all at once, everything else is just hype.
now its a lake.... beautiful
We'll call it lake Fourdays
Not for long, it's not!
Geology in real time, usually one would have to sit around for a hundred years to see something like this. I saw the helicopter flight up this river and it looks like a whole lot of places where this could/will happen.
I noticed the same thing watching that flight, with one spot in particular that already looks to be underway.
Nature at it's finest.
Imagine if that ‘hold my beer while I continue fishing’ guy was your Dad. 🤦♀️
It’ll take something like 20+ hours for any kind of flood to make it to the Fraser. He’s right, there will be plenty of warning time.
How dare you assume the identity of that person? 😮
@@MtHoodMikeZ but why risk it? How does that seem worth it, just fish somewhere else. It’s silly, and if he gets hurt, selfish and irresponsible.
@@crakkbone you still wear a mask don't you? Turn off the corporate fear propaganda and enjoy life. This won't even burst, it'll create a new pond along the river. Have you never witnessed nature first hand?
@@MtHoodMikeZThere may be plenty of time but whose to say you would actually receive suitable warning in time. It's not as if those emergency alerts are instantaneous either, especially the smart phone warnings as those are point to point communications not broadcast communications like TV's and radios. Does he have a radio constantly playing through an ear bud while he's fishing? Besides telecommunications, especially cell phones are spotty throughout the mountains. The advice to stay away from the rivers is because people have been washed away in the past so there have been cases where people did not receive warnings early enough or maybe not at all despite that it does take some time for the water to propagate along the length of the river.
It will do as nature intends.
I don't understand how people get so worked up. They should be grateful there is advance notice and just deal with the eventual consequences. Life is uncertain.
It's going to take a long time for the new lake to drain. A new stream is going to have to figure out a way to cut through the landslide, which is huge. It's not going to get pushed out of the way all at once.
They’ve been saying 24-48 hours for over 48 hours now
@@Shadow_Lurker968 Yeah if the water crests the dam - which is inevitable at some point, that loose soil and debris will collapse fast.
“The Experts”
I knew when they said that 24-48 hrs. They had no idea, but wanted to get the public panicked. Because if it does break loose there could be a series of mini disasters all the way to Hells Gate canyon. But it could be more like the Big Bar slide. Tough for fish but no major disaster.
@@festerofest4374 🤔👈😉👉🤣
It’s 24-48 hours since they said it last don’tchyaknow?
I'm no expert but when it first happened why couldn't they blow it up.

Yeah, or even now; blast a small channel or something.
It would require someone to put a drill rig on the blockage which might give way at any moment.
By the time they got the equipment for it up there, water would have built up a lot by then, and also if they blow the dam & it causes damage, they could potentially be found responsible for it
@@Plutogalaxy I guess you never blew up beaver dams
Sending positive vibes to everyone that is affected by this situation. I am at the mouth of the Fraser but so far no warnings here.😮
I would imagine it would slowly start to beech the top then very quickly start washing out the dam. Won’t be a sudden burst but once enough water flows over the top it won’t take long.
My guess too.
When earthen dam parts overtop, they just disintegrate.
And this stuff isn't even properly designed or compacted.
Mostly I wonder: Why not just open it, to limit the water buildup?
@@christopherg2347 >Why not just open it
Because that would be a mammoth undertaking putting man and machine in grave danger and probably take longer to mobilize than this thing will take to breach on its own.
@@nspro931dynamite
@@nspro931 Explosives can do the job.
Just give it a channel to flow, and the landslide will be gone in hours.
it's a landslide, very loose and not structurally sound in any way. Water could be tunneling through gravel and sand only for the dam to give away in a giant rush. Stuff is very dangerous and unstable
I pray everyone in the path gets to safety ♥
Nice thought but in reality we all know that prayer doesn’t do anything.
@@RedRoseSeptember22 praying is a bit lax.
If you want to help get out there and help. If you don't want to help that's fine too. But asking God to do something on your behalf is a little bit too lazy for my liking. He's giving you arms and legs use them
@@FYMASMD I couldn't disagree with with you more. Prayer permits the lazy people to Pat themselves on the back
Over hyped fearmongering, as usual. Its going to do almost NOTHING!
Don't think twice just move out before is too late.
Another video said people would have 12 to 24 hours notice for the Frasier River. There is not great fear there.
@@Machoman-mp3hm - there is a lot of door knocking going on right now.
@@Golfnut_2099they also said that the Fraser won’t raise past spring peak either. It won’t be that crazy on the Fraser but hells canyon and other places will be interesting.
Hells gate canyon*
@@somethingsomething404 ....and WHO lives close to the water near "Hell's Gate Canyon"????
.
I find this fascinating but don't think it's going to 'burst'. My uneducated opinion is that when the water finds a path over, it will cut its new channel and meter the flow to some degree. The river downstream is lower if not dry, so it should handle the extra volume.
Yes, catastrophic failure of the blockage would be.... catastrophic, I just don't believe it will fail that way.
The 1964 slide eroded down about a foot per day. That slide was about two weeks later in the season.
Prayers to all 14 people that will be affected by this
"experts are most concerned about sockeye"
I'm sure Jesus and Darwin will take care of everything else!
😂😂
@@jgp7414 14 people live downstream from this.
@@jgp7414 correct
The dam is one km long. It is not going to burst.
When it overtops, it won't be much different from a burst caused by seeping.
Tell me you know nothing about loose material without telling me you know nothing about loose material.
It all depends on the configuration of the logs, and soil characteristics. Some of the soil may not be loose. It would help if we knew the soil characteristics, and the base flow in the river
I don't understand how they think it's going to crest the top and then that's it. I'm no expert but I'm almost 100% positive that once the lake behind the slide reaches the top it will just be a matter of time before the water fully saturates the slide debri and then undermines it before it all let's go.

It likely won't burst. But I will start seeping beneath the dirt. Slowly at first then full on. I don't think it will flow over. But the river will be once again. Very soon
Rainy season is a month away, means this will swell and flood towards the coast, why isn't that being mentioned 😮
It could over top but it could also saturate for along time. Its so huge that its hard to imagine a sudden failure but dont take a chance get out of the path.
because of how sandy and dry the soil is, there will be rapid erosion around the breach or channel it over tops at. Which will dig it out faster and faster releasing a relatively rapid torrent of water down stream
Sounds likely i live under Ororivile dam ca. And it was starting to happen there it is just how fast that is scary. Water is very powereful.@@avroarchitect1793
Hells Gate canyon could be a disaster with all the displaced trees.
There's actually areas that are more narrow up the river too.
@Broesky thanks for the note
Will those pressure points wipe out roads, housing or communications?
Well, the aerial tram could go back on the map with this new "feature"
Now THAT might be a real possibility .....but this is NOT going to happen over night ....nor over 24 hours, ....nor over a week, ......nor over a month. No one, especially any attending "experts" have come close to describing what IS going to happen .....but it most REALISTICALLY ....IS GOING TO TAKE TIME FOR THE WATER TO CUT THROUGH AND EVENTUALLY AFFECT ALL THE BLOCKAGE. THIS IS NOT A DAM AS GOSSIP SOCIAL MEDIA HAS INSISTED ON DESCRIBING THIS SITUATION.
.
who are these people? they're in charge? 1km long? i saw a video from two days ago of a helicopter flyover and the new reservoir was easily at least five kilometers long. it's getting bigger every second. and at least 100' deep at the dam, probably that deep for almost the entire reservoir.
Why not dig a channel and let the river dig a new base.
Exactly. You can actually see where the water is at it’s highest point and the general direction it’s going to take. So that’s where you would start digging a channel. Don’t think they could get heavy equipment in there tho…🤷♂️ maybe some Bobcats and a lot of people shoveling..🧐
@@joeskill4663 yeah too remote for anything significant. And that pile is mega unstable. Too risky for people. It's too late/deep now but given how remote it is, small uncontrolled but predicted releases via dropped explosives seems preferable to one unscheduled massive catastrophic one. Works for avalanche protection.
So, the Chilcotin River is essentially completely isolated from major cities and towns. There are two roads you can use to get to it: Farwell Canyon Road and Chilcotin Bella Ccola Highway according to Google maps. So the first issue is remoteness - how could we get enough heavy digging equipment to this area. Normally this wouldn't be an issue, but there's only so much time.
Even if we had all the time in the world though, looking at Google maps reveals the Chilcotin is at the bottom of a steep canyon. While I am very certain laborers have done more with less, that definitely plays a massive role as to why this option isn't being pursued.
Tldr; the logistics of getting there, getting down there and beating the clock combined together make such an endeavor nigh impossible given the circumstances.
Good reasons. Research instead of chirping.
Cost, risk, low probability of success, high probability of losses, injuries or deaths. We might make it worse.
Dunce caps for everyone.
Is there a road nearby? Place for a big helicopter to land?
Quit crying. Mother Nature just made a new lake.
“Giant water gush?!” Global’s grasp of technical terminology is always impressive. “Biggie, quicky, floody thing” or “catastrophic rivergasm” might also work.
It’s gonna be a “super soaker”!
Better than trump “very wet in terms of water”
At least it is not "atmosferic river"!
Over hyped fearmongering, as usual. Its going to do almost NOTHING!
No worries. Mark my word it will not burst. It will start cutting a new river bed through all that land that slide and blicked the river. This will be really cool to see what it does with making a new river path.
Over hyped fearmongering, as usual. Its going to do almost NOTHING!
@@kidwave1 Exactly, way to much land in the way for it to "burst" or cause any real threat.
I realize that the quality of journalism has taken a dive but could you please get the place names right ? In BC the region you're reporting on is in the Cariboo not Caribou.
There will be hungry bears.
drone flying made illegal today. Do you have word if mouth of river is dry? 600 meters of blockage , we have another week+ before this tops over. Why not dynamite a channel out now? That salmon run is going to be wrecked for years.
Possibly wiped out.
Canada loves its totalitarian control.
@@Trumpulator gov presser today said most of the chinook run had passed
sockeye coming up now. Gonna be a mess.
so call me stupid but what's to prevent them from laying an explosive path through the blockage to drain the buildup instead of waiting for a catastrophic breach.?
It would be very easier to build short pipelines with pumps to carry water over the landslide while plans are made to remove the blockage to prevent damage. Once that landslide is overtopped it will be only a short time for the landslide to be breached and have an uncontrolled release
1:29 - salmon freaking out about it!
Unless there is a torrential rainstorm that river is not going anywhere soon. Isn't B.C currently having excessive heat?
What does this have to do with excessive heat?
And nobody said the river is going anywhere...
yeah it's summer. lol
Another 10 days I bet. Yes heat = snowpack melt = faster rise.
Nature means business. Stop interfering 😢🛡
This is how lakes were made for millions of years, I love how humans think they can put themselves in the path of these things and think they can change it
Well I'll be damed
A similar thing happened in tasmania in the early 1900s , it took years to clean up
Clean up? Just leave it alone as it lies. Where are all the ecofreaks complaining about disturbing nature?
It should not be a surprise... Do a scan of the top of the slide. You can then predict pretty closely where the water will go as the river rises behind the slide.
why are they not digging a small channel so they can manage and direct the water and get it moving instead of waiting for it to build up to to a unmanageable flow .. the higher the water gets the worse its going to be when it does breach ..
Not safe enough to do that
and also it isn’t really possible
Can they not help by carving a path through that section to help the water flow through. I know nothing about this and am asking so I can understand better, not because I think I know anything about it, so please keep that in mind when responding.
I realize that wouldn't be as simple as it sounds and would be a huge undertaking.
What, don't they have escavators in Canada? Fly a backhoe out there, dig a little canal and the water will do the rest.
Gold
That Sturgeon fisherman has a bit of an Oceangate vibe going on about all of this.......
when it goes over the top the rapid erosion is essentially exactly the same as it "bursting". this thing is going to be _BAD._
why not have army EOD place charges to relieve instead of waiting for mass damage
Why doesn't someone turn the water off?
Seriously. Surely someone in Victoria has Poseidon's number
Someone did. That's what the landslide did.
@@stevenweaver3386 If the water was turned off, it wouldn't be building up.
@@shelbyseelbach9568...that's literally what happens when you shut the water off.
@@Holy.HannaH No, if it's shut off, it LITERALLY, it stops building up. It's building up, because it's still turned on. This is the equivalent of a blockage in a pipe. Ultimately water can only be truly turned off at the source.
Why is global news reporting that the Fraser river flow rate is 300 cubic meters per second. Its 3700 and in freshiit up to 17000
It will be something to see.
Call me uneducated, but could the military not come in and shoot mortars at it in order to blow a trench for the water to start passing through? No one would need to be close in order to do so. And you could do it in a slow controlled manner letting the river advance little by little
Where is the Canadian Military with a few well placed JDAMS from the aging CF-18 fleet, we could’ve cleared that significant blockage the next day without incurring a giant build up of water, with the potential property damage and loss off life. Just a quick little training exercise out of Cold Lake, Alberta….but hey, let’s just do nothing, and observe and report.
That soil is more compact than they think. It seems it will fill and crest the top, then once the water gains speed again its gonna rip that earthen dam right away.
I bet you it will most likely breach the dam by overflow when the maximum height it can go is attained.... So to further explain, when the overflow starts, that will also be the point of most vertical advancement..
It would help if we knew the flow rate in the river. There seems a chance it won't be catastrophic, if the logs help slow erosion and if the soil is still consolidated.
There's a gauge a little ways upstream which has been reading around 200 cubic meters per second. The BC River Forecast Centre Discusses their modeling of the potential downstream flood in their latest warning.
The flow rate in the river today was 202m3 per second.
The flow rate would equal approx. 5200 olympic size pools per day.
@@MrSnowmover So how long will take to reach the dam top, if one assumes there is no leakage or erosion, i.e. just as it stands now ? That would be one data point
@@MrSnowmover TY! That's a lot of water. It could def cause erosion of soil. )o:
Would it be possible to open a small canal - or maybe two small canals - around the landslide to release the water pressure? How long would that take?
O no a natural disaster how ever could the fish survive what they have for millions and millions of years
Yeah, like this never happend before.
No pictures of the slide ??
Let's all pray nature does its thing. We can learn of many geological phenomnah from this event, such as the formation of the Grand Canyon and the Columbia river basin.
Mother nature is like I’ll put an instant damn here right now boom 💥
I predict it only takes a few hours for the mud slide to be washed out after it breaks over the top
Has happened many times before. Stop trying to scare everyone
Not with towns downstream.

@@jeepstuff4004 If this is so common, when was the last time a river in North America got dammed by a landslide of this scale? Yes, it has happened many times over geological history, but not in recent human history -- the history when there have been towns downstream.
@@ohsweetmystery
Yes, because they're being informed by others such as the media
It will eventually come over the top and carve a new channel.
Possibly release catastrophically as a Bosporus.
I don't understand how they think it's going to crest the top and then that's it. I'm no expert but I'm almost 100% positive that once the lake behind the slide reaches the top it will just be a matter of time before the water fully saturates the slide debri and then undermines it before it all let's go. They should be trying to clear a path to let water through now before there's 10 billion liters backed up. Good thing to know our leaders will do nothing just like in Jasper.
Probably be good if they started removing logs from the lake. It will start off slow and begin carving out a river through the slide area. But once it gets going and those logs are flying through there it could get ugly down stream..🤷♂️
Over hyped fearmongering, as usual. Its going to do almost NOTHING!
1959 Hebgen Lake earthquake (also known as the 1959 Yellowstone earthquake)
occurred in the western United States on August 17 at 11:37 pm (MST) in southwestern Montana
They should know what needs to be done if they have the man power
The lake it created is still there called Quake lake ,the slide materials was lots of giant boulders that formed a permanent dam.
It isn’t either overtop of fail catastrophically. Most likely first it overtops and that causes a catastrophic failure.

or over the top and a gradual (fast but slower than a sudden failure) erosion which will unblock it.

Do we have an estimate for the burst time? I'd like(probably can't) to as well as plenty of people to see this once in a lifetime thing happenning.
anyone know what caused the landslide?
This ain't no little beaver damn.
Prayers for all,Affected. ❤
Would be nice if someone would do the math with the rising water lever to calc. when a over top is due!
As thats the hard max. time limit!
And probably also worst case as its more water and upstream embankments could be unstable after a sudden release of that hold back water.
A "calculated guess"??
I prefer WAG, Wild Azz Guess
Yeah, I'm still waiting for the calculation too..
By the shape of the slide the river will be doing a few turns to get over the slide.......when it does start flowing over the slide the water won't won't be able to quickly dig out a trench that will cause a huge release at once
I my opinion this is the best case scenario for how the slide settled but trees grass and bushes and other debris will cause problems downstream for sure
Once the water finds a way to apss the blocking masses it could cut a totalt free way within hours. This has happend in other places, once due to man made attempts to cut a "small" channel using the water flow.
That's not going to blow, it's too deep and too long.
The river will carve a new path with new riverbanks.
I wonder when the max capacity is reached? ( river flow & total volume )
how close to the top is the water? How much is it rising every day?? How deep is the lake??? Some piss poor reporting!!
If it goes today, then it will have the same anniversary as Mt Pollley, August 04.
That background with the northern lights..... 😂
Wow! Nature expressing itself ……
Had good luck gold prospecting last few days south of the slide. Going back tomorrow for more 🥇
this is nature at its finest. why havent they dug a channel for the inevitable water flow to follow for one thing and i wonder if they are preparing for washed out bridges and roads . im only sensing helplessness and panic and not much help from ottawa
over the top, saturate, burst
Would be a good idea to buy some of that new lakefront property
Keep me posted!
Can the not blow it up to break up the blockage?
I heard there was 1 person that got hurt in the slide, should they be drug in for questions as to why that person was there and what kind of explosives that were used ? 😊
Maybe it will cut a new channel around the right side looking down river.
"Giant water gush"... ROFL. They now have 12 year old experts looking into the landslide!

@K.C-2049 "Experts say that the lake is gonna get rilly big and it might pop and go fwoosh and stuff. Residents are warned to watch out and get their rubber boots ready. This is Susie McBoogers for CBC news, back to you Brian."
Let's all avoid that Hope fishing excursion outfit.
His bottom line mote important than his guests.
Guys like this always justifies their actions
He's correct though. The water wouldn't even reach Hope for like 12 hours if the damn is breached.
A "giant water gush" ..is that an academic term?
They should research Earthquake Lake, west of Yellowstone National Park. Same thing happened. They quickly brought in a bunch of dozers to cut the top down so the water would gradually go over the top and slowly erode a channel through it.
No amount of prayers will stop the water from breaching the dam.
Thanks for the news on the slide, wasn't enough seeing " models' of what's to come.
Thank you for pronouncing kilometer properly!
Start digging!
Come you people just don’t play with the dam that compaction is strong just nature has made it stronger
Where can we find information from people who acutely know what's going on?
Here's your information you requested. There's been a landsl 0:57 ide, the river is currently blocked from flowing, eventually the water will build up and overflow the blockage and everything will slowly return to normal. Normal means this will happen again in the future, and then again and then again. Nothing to see here folks
Here's the information you requested. There's been a landslide. The river is currently blocked, the water will build up behind the blockage and then wash the blockage away. Then, there will be another Landslide next year or later this summer or in a few years from now and the same thing will happen again. There are no experts on things like this. We just got to watch the show if you're interested
It reminds me of that slow motion steam roller scene in Austin Powers.
That is unfortunate.
All thirteen people where evacuated.
Not a big deal.
But keep building up the story.
Get a camera on it!
