BC landslide: Chilcotin River dam overflow more likely than sudden burst, officials say

According to B.C. officials, the most likely way for water to start getting through the Chilcotin River landslide dam is a gradual overtopping — but plans are being put in place for other scenarios, including a catastrophic breach and flooding.

The situation around the landslide remains dynamic and ongoing, according to Minister of Emergency Management, Bowinn Ma.

She adds if and when the water breaks through the landslide dam, it will take between 12 to 24 hours to reach the community Hope downstream on the Fraser River.

    Overtopping leads to sudden collapse of a non-compacted dam. This is going to be horrific.

    Well if I was a land owner at the dam area, next season I’d be sampling for alluvial gold deposits in what is left behind. The entire water way of the Fraser and its tributaries are well known for alluvial gold placer deposits. It could very well leave placer gold at surface levels not seen in over 160 years, that’s a lot of ground that is going to be naturally sluiced by nature.

    The water will start slowly running over it but because the slide has a compromised structure the water should eat through it quick would be my thoughts so if it was me I would get the hell out the way
  • Great reporting however you have not shown a map of the area impacted.
  • @ownedurfase
    Where’s Noah? We need a bigger boat when this breaks 😳
  • @bethhillier1294
    I think they are down-playing what will happen. I'm can't believe the Province of BC is going to 'sit and wait' to see what happens. Unbelievable!
  • @rosspayne2235
    If i was down stream after the water stopped i would have got as many 5 gallon buckets of mud as i could its probably loaded with gold 😊
  • Would be really cool to see a Timelapse of the water filling to overflowing!
  • @sluggou812beotch
    I remember when Lake Bonneville let loose. It was exactly the same scenario but on a much grander scale. A little trickle at first but then the loose substrate gives way and water takes the path of least resistance taking the earthen dam with it. The Corps of engineers should have 25 D11 cats out there digging a relief trench.

    Judging by the size of the slide, it could be a week or more before tops. Of course, it’s just an opinion of some random YouTube watcher.😗
  • @Aitch-102
    I disagree, none of that material is compacted, once water starts to flow it will erode VERY quickly.
  • @Summitspeedfly
    Looks like there is time to build a compacted and cement lined spillway before it crests. Or at least bury some large pipelines to direct the water over the top.
  • @SotR59
    In actual pictures the slide is much bigger than it looked in a graphic. The river doesn't look big enough to push that much dirt any time soon. Would hate to be in the path.

    When I fly from Toronto to Vancouver years ago, I saw the Rocky close to Fraser Valley has lots of geographical erosion.
  • @ReginaRedding
    All that water is going to go around, over, or through that debris.😮🙏
  • Get the military engineering department to blow a path through this , controlled

    Over topping is only about 5 min different than a ‘burst’
