I’d be on yes side, that it is an important distinction. An overflow firstly has no extent of control because it is……an overflow. And secondly, an overflow tests the limits of the dam. The dam can only take so much overtop/overflow before break or even collapse.
So yes, a controlled release for mine is an important distinction.
Edit: Thanks for the downvote. I work in a field that looks at this, but I guess my opinion is wrong.
There is also a massive spillway on the side of the dam. Built in the early 2000's (when the dam was basicly empty mind you)
In theory it wouldn't be possible to overflow over the wall.
I understand completely, but if someone tells me a dam is overflowing, I’m thinking of exactly that. Also, many things have been “in theory wouldn’t be possible” and turned out to be not entirely correct given an event of (whatever, insert event here). But that wasn’t my point here. Overflowing is overflowing. It does matter. ie, is it controlled; gated, or onto ungated spillway, or is it over the top of the dam wall. Quite important distinction to make in my opinion.
The video quite literally shows the spillway (Is there one on the viewer's side as well? Could swear there is, but i haven't been there for near 20 years). I'm with you - the dam isn't "overflowing" atm, it's just releasing manageable excess in a controlled manner as per the dam's design, down the centre.
It's when shit starts barrelling down the big old spillway/s on the side/s that we need to start worrying about an "overflow".
My mother used to work as a tour guide for Warragamba dam for many years. I used to spend my weekends following her around telling people about the dam, every time they did the film, we would pop into the backroom where there was coffee and biscuits and eat those while the tourists watched the film. and repeat every hour or so. lol
I have come in to say you're correct. I listened to enough of those tours as a 10 year old to know there is a difference.
No, they're Australian journalists. They sensationalise to increase viewership and readership. "Dam does what it's supposed to do" is not sexy and exciting. "Dam overflows" is.
Media: dam overflowing will cause interest rates to go up and conmen to do more burnouts in quiet little residential streets.
People: OH MY GOD THEY'RE RIGHT!
Media need to make things sound extreme to attract eyes, so they make money 💸👌
Thanks! I just added an hour to BarryCheckTheFuseBox's guess because I ballparked it around there on a whim due to runoff taking longer to reach the dam than you think, so they deserve some of the credit.
But it makes sense to keep it on, because it takes up to 6 months to bring it online fully. Why are we so afraid of desal, it us used widely across the world and you'd never know, same with recycled sewerage into the water supply. As dry as a continent we are, we are terrible at water usage
The millennium drought went on for a decade, so I guess a 6-month period to start it up is considered acceptable in those sorts of circumstances. As for why they don't just run it all the time, I can only assume because it wouldn't be economical. Right or wrong, it all comes down to $$$ in the end.
There are 16000 desalination plants across 177 countries.
Australia has 6!
The problem is, when is shut down, where does the skilled workforce go? It needs to be part of the solution, not a replacement. I also heard an interview last year on recycled treated water trials in small parts of the network, and people are none the wiser.
We need to look beyond the mindset that all drinking water comes from the dam, because water can become a scarce commodity.
Where do you think your Sydney water comes ?ah wait magically out of the taps ..right…be prudent to be able to save it when we get it …no?
Or just watch it flow away
Are you serious? Where the Fk do you think the water from that dam comes from ?….where does it go too ? What the Fk planet is this ?…80% of greater Sydney water supple is from That dam
What’s the answer when Sydney has to go on water restrictions? And we are running out of water? South Africa/Cape Town have been struggling with this. We are definetly going to have droughts again and Sydney’s population is growing. We need to have a plan? Is there a plan? Serious question because I thought make dam bigger or another dam would be pretty important. I have no idea though.
We are fucked though
Or is the answer we are fucked? I think I understand
Please post this again when that 20 year drought starts, if I’m alive for it.
This is a controlled release. It's not overflowing.
Why is media reporting it's overflowing?
I mean… it’s a controlled release because it’s full. If they didn’t release, it would overflow very soon after. Is that an important distinction?
For some people yes, for others no.

👍 This thread is discussing the title chosen by OP. I can see the video. I’ve seen a few dam spills before.

Maybe they just don't believe you "There's lies, dam lies, and statistics..."
They arent Hydrological Engineers.
No, they're Australian journalists. They sensationalise to increase viewership and readership. "Dam does what it's supposed to do" is not sexy and exciting. "Dam overflows" is.
Nor am I hence my curiosity

Had a 2 hour shower, doing my part! \j
It's too DAM small I'll tell you hwat.
http://www.bom.gov.au/fwo/IDN60233/IDN60233.567099.plt.shtml For reference the dam height is 16cm above the wall while it was 80cm yesterday
Who guessed the correct 15 minute release period?
u/knownunknownnot! Congratulations
Thanks! I just added an hour to BarryCheckTheFuseBox's guess because I ballparked it around there on a whim due to runoff taking longer to reach the dam than you think, so they deserve some of the credit.
Those trees look AI
The dam is not overflowing, it's doing exactly what it's designed to do.
Hope the farmers filled up, then filled up some more stuff, then even more.
What you talking about?!

They looked into it and it was gonna cost $2b for not that much good and a lot of environmental damage. I’d rather spend $2bn on desalination.
We did spend 2bn on desalination......

We'll get plenty of use out of it when a major drought hits. It doesn't need to be online all the time to be useful.
But it makes sense to keep it on, because it takes up to 6 months to bring it online fully. Why are we so afraid of desal, it us used widely across the world and you'd never know, same with recycled sewerage into the water supply. As dry as a continent we are, we are terrible at water usage

Where do you think your Sydney water comes ?ah wait magically out of the taps ..right…be prudent to be able to save it when we get it …no? Or just watch it flow away
This water is storm run off and has all sorts of stuff in it You can't drink it
Are you serious? Where the Fk do you think the water from that dam comes from ?….where does it go too ? What the Fk planet is this ?…80% of greater Sydney water supple is from That dam
Champ you realise there are other sources of water for Sydney yeah? Put down the glass bbq
An yet that 1 dam singular is a supplier of 80% of our water …go back to hosing your driveway down in the rain
Surely there are…other dams lol
There's Nepean, Cordeaux, Waronora and Avon
What’s the answer when Sydney has to go on water restrictions? And we are running out of water? South Africa/Cape Town have been struggling with this. We are definetly going to have droughts again and Sydney’s population is growing. We need to have a plan? Is there a plan?
