I feel your concern bartholomu. Events like this flood (as well as severe cyclones) make me really anxious. I barely slept last night, fretting about the heavy rain that seemed to just keep coming. And this flood is unprecedented in modern times, so I think we'd all be justified in being a little uncertain about just how bad things are going to get.

I've spent a bit of time reviewing the EAP myself today, and as a resident of the pink zone, if I've interpreted correctly, then we'll be subject to inundation at a dam height of 43.60m. It's concerning that the dam level is still rising, despite the gates being open wider. Yesterday it remained pretty steady for a period, but not today.

Ross R at Ross River Dam # 6.33pm Fri 41.51 rising
2.96 above Spillway

So, will the dam operator go to transitioning fully open?

I reckon not. Politics.

Fair enough, the people downstream are in the firing line. But then again, dam or no dam, they always were.

With all the talk being about highly professional dam operators supposedly operating with an ulterior motive, it might be a good time to warn locals of a text being circulated, seemingly coming from a local disaster group, it claims dam wall failure is imminent and to evacuate certain suburbs immediately. Poor spelling and advice give it away to most, but it pays to be vigilant as there are some strange ones about who must be doing this for enjoyment.

Spot on CF, just love watching them build as they head south down the coast. you must miss it up this time of year?


Yeah I loved the wet but prefer the climate overall down here mate. Feeling cool in Winter is something I didn't think I'd enjoy until last Winter.

Ulterior motive? What are you suggesting?

If the procedure is to open the middle gate in transitioning to fully open at a certain operating point, and that procedure is not followed, is it purely down to the "highly professional staff" to make that decision unilaterally?

I think not. That is politics.

You will find short term forecasting is to be considered with dam management in record flood type events.


Can you post your qualifications about reservoir management? ....else sit back and monitor your copy of the operation manual and post your observations post event. Very alarmist.

And there you go. I fail to understand the rationale for attacking people for their concerns( unfounded or not) over the unprecedented inflows into the dam.

Currently 190%

No evidence of increased flows to the weirs below, and another big band of rain not far away.

Post event, indeed.

Hello Salty,

I'm suggesting that the operation of a dam during a likely historic flood event would be one of the most highly scrutinized jobs around. I'm suggesting dam failure is not an option for anyone involved and the idea that the system would be deliberately mismanaged for political gain is beyond ridiculous.

As for the lack of evidence re Increased flows to the lower weirs, there has been very little rainfall within their smaller catchments over the last 3 hours and they react quickly to this. I don't claim to be an expert here but I assume that the 40m or so wide dam spillway isn't feeding water downstream as quickly as the 150m wide weirs are offloading it?

New severe weather warning out. Areas north of Cardwell removed. Looks likes the monsoon is staying put and not going on a trip north.

Just putting my 10c in... have been avid follower daily (on the sidelines) since Yasi living in Cairns before moving south. Apart from all the "forecasting" the other side of the Forums are when the sXXX hits the fan and real time info and discussion is precious and well received...I believe voicing concerns are important, as those in the know (hopefully) can explain or allay any concerns or fears...
Oh, and to our Townsville friends your doughnut hole looking more like a swimming pool... stay safe...

I am not suggesting dam failure either. I am suggesting we are in unknown territory. Seems to me those weirs will react pretty swiftly to full flow from the middle gate. Particularly Black's.

41.53 AHD, and steady as she goes. Let's hope it doesn't rain...

(you clearly have a higher regard for politicians than I do)

Haha certainly not impressed with the current crop of politicians at any level eek
Let's hope we all get to enjoy this incredible rain event with no further damage, after years of the Weather having all kinds of excuses for missing us we're in the right spot at the right (wrong?) time.

Petro, I am only to happy to supply you with my qualifications when you are sitting in a deck chair at the ross dam park directly in front of the ross dam wall and book in to stay for 2 weeks. Jetstar are still operating direct flights from Melbourne. I will even drive you from the Townsville airport to the ross dam park. It is a bit rich to call me alarmist as you sit in your chair in Victoria, when the QLD premier just backed the local council to release water early, intervening in the EAP operating manual, I only hope I can post a comment post event, that is why I am commenting now Petro, as my survival chances being 3km from the ross dam in the event of a dam failure are ZERO. I do not want a failure to Occur, I will refrain from commenting when I meet you at the dam car park, or the moderators of this forum request me to.

Early intervention regarding water release when faced with the forecast in the ross dam catchment is what I have been praying for, at 120% the ross dam should have been attempted to be drawn down to 75%, it was unlikely to have been attained, yet we are in real time not hindsight so public comments do count one would hope. The Ross dam is a fantastic flood prevention device until it becomes so full its role is reversed. The situation for we who live in the flood zones it causes a loss of sleep due to the unknown territory that comes with dam levels that have never before been experienced. Oh poo it starting raining heavy again.
