Just a thought:

What the hell? Billions to CBC and no one can provide a 24-hour feed on this?
Water seems to hitting the Fraser without too much rise in the level, but full of debris.
Our town’s riverside boardwalk is closed but this seems an abundance of caution rather than active danger.
You never know when a big tree might come along and smash something. But glad to hear things are generally okay.
If you wanted to get the flow down to 20 kph, you’d need a pipe over 6 meters in diameter. Apart from building such a monstrous siphon, the other challenge is how to prime it: you’d need to valve off the downstream end and install a vacuum pump at the highest point. And your siphon would only work until the upstream level falls to about 30 feet below the highest point of the siphon; any more than that, and you start creating water vapor bubbles at the top that will unprime the whole thing. You’ll then have to reprime the siphon once again after the upstream level increases, and repeat the cycle ad infinitum.
That was pretty much the city’s exact rationale: from their Facebook comment on the post announcing the closed boardwalk, “The risk is that the landslide debris being brought down the river, combined with increased water flow, could potentially damage the boardwalk. We appreciate everyone’s cooperation in following advisories to stay off of and away from the river at this time.”
I agree that the live / near-live coverage has been poor.
The best summary I’ve found is from the GeologyHub YouTube channel (a good one).
The unstated real reason:
We know that if we leave the boardwalk open, lots of people will congregate there to take pictures. And of course somebody will fall in. And if anything bad happens with downstream flow or debris or undermining the walkway we’ll have a mass casualty event.
Smarter to prevent the public from being their usual moronic selves by simply closing off this attractive nuisance before they get the idea to be attracted to it.
This. So much this. It seems like people just keep getting dumber and dumber about that sort of thing.
Flood surge appears to have dissipated, but concerns about the banks of the river being unstable and dangerous.
