Well they are close to full, now a cyclone?

[Tropicaltrout]

so what's the thoughts on this the dams are close to full and now a cyclone is spinning out off the coast by late week it may make land fall. Does this mean by its slow southerly coarse the already close to full dams will spill :end:

Anyone got any thoughts man it would be a bugger to see fish go sailing over spill ways all over:lipsrsealed:

well i think it might be a bit breezy next weekend but i think the cyclone might start drifting south and hopefully the high's pushing accross may keep it off our coast and we may only get showers hopefully

Hey Nath,

There's a good story from BOM about how little this cyclone will affect Queensland other than some coastal gales. No mention of any rain impact though...

I have pasted the story below.

Don't panic: cyclone fears dismissed

March 15, 2010 - 6:55AM

Fears a category five cyclone would cut a destructive path through northern Queensland this week have been dismissed by the Bureau of Meteorology.
Cyclone Ului is not expected to hit land at any time, forecaster Vikash Prasad told brisbanetimes.com.au this morning.
''It's not expected to hit the coast, [which] is something that is exciting a lot of people and we don't want any panic,'' Mr Prasad said.
''The cyclone is 1500km away from the [North Queensland] coast and moving at 10km/h, it's a very slow system. If you're going from Brisbane to Cairns at 10km/h how long will it take? That's how it is.
''It's going to slow down further so we're not expecting it to hit the coast at all and it will remain out in the Coral Sea and start moving southwards after Tuesday.''
Mr Prasad said Ului would remain at least 1000 kilometres from the Queensland coast and as it moved south would stay about 500 kilometres off Fraser Island.
''We're not expecting any direct impact from this system at all,'' Mr Prasad said.
''[North Queensland residents] can relax totally. As long as they're not going out in the water you'll be fine on land.''
Strong wind warnings are current for offshore waters but do not apply to inshore waters.
Mr Prasad said the winds would be marginally gale force and similar to winds experienced at the weekend.
The cyclone is now a category four but is expected to re-intensify to a category five - the highest BoM cyclone category - later today.
It had rapidly intensified from a category three to category five on Saturday night before weakening slightly in the past 24 hours.
A spokeswoman said Emergency Management Queensland was monitoring the situation.

That would be interesting if some of those big mummas ended up in the rivers below Awoonga and Mondy.

Nate - its overflowing still at Borumba. On Saturday we also saw plenty of evidence in the backwaters that it was nearly a metre higher than now. They must have lost a bucket load of fish over the wall.

[tiges]

The media always go into a frenzy over cyclones and other natural phenomenon. They love to beat it up and make a huge story out of it.

That said I think Mr Prasad is a little premature about discounting totally, a coastal crossing. Sure the steering systems and general trend of cyclones suggest this one will not cross. But as they say, "the only thing predictable about cyclones, is that they are unpredictable."

FWIW I hope he is right about it's path. Not only because of the impact of more water, and the destruction it will cause those in it's path. But because it will create some of the largest surf seen in a long time, and the points at Noosa and Rainbow side of D.I. are primed for a big swell.

Tuesday.''
Mr Prasad said Ului would remain at least 1000 kilometres from the Queensland coast and as it moved south would stay about 500 kilometres off Fraser Island.
.




I think that Mister Prasad should look at a map!!!!!!!! Because the last i looked Fraser Island wasn't 500km's off the qld coast!!! The above statement just doesn't make any sense!

[hkconc]

with the land saturated, the rivers and dams full, things can only lead to floods.
Thats even if it dosnt cross the coast. If it does cross the coast, it will lead to the biggest floods on record. You dont need to be a guiness to work that out.

[jayvee]

i have a trip planned to mondy this weekend so it can stay as far away as possible as far as im concerned....

[FNQCairns]

All 5 or so of world wide predicting models are pretty much in agreement ATM it's going to get very wet and possibly a little windy in 6 days time more or less down your way.

Actually it's not often they do align like this for a system so far away, I am no expert but i follow these closely because of where I live.

It's the first time i have seen such alignment over 10years, only one model disagrees and has it by then further north.

cheers fnq

[Steve B]

Agree FNQ.
THere is this NZ predictor (who guessed all the last lot of rains) who reckons the Bundy area will get another 600ml before the end of march!!!!...geez I hope hes wrong...But like you said, when that many 'respected' forecasters think along the same lines of prediction.....well?????

Wyvenhoe was initially built as Flood mitigation.

I hope they have opened the gate.
You cannot stop a flood with a full dam!

But isn't it classed as being full at 50 to 60% capacity.????

[quote=darylive;1142225]Wyvenhoe was initially built as Flood mitigation.

and in their infinate wisdom they built Wivenhoe on the most active fault line in QLD!!!...wouldn't like to be a bris-ite, if we get a decent quake.!!!

Steve

[tunaticer]

Wivenhoe actually has a full capacity of 100% and a flood mitigation capacity of almost 75% more above the full level. It was designed and built primarily for flood mitigation and water storage.
None of the other dams were built for flood mitigation, only ones with overflow spillways do not have some form of over capacity mitigation. Dams like NPD that have active floodgates offer controlled overflow in the form of flood mitigation.

So basically we would need 3/4 of the rainfall we have had in the past 2 years to over fill Wivenhoe and actively flood Brisbane.

[robersl]

Yes wivenhoe holds 2 times the amount of sydney harbour when considered full but on top of that they has 3 times the water held in sydney harbour as flood mitagation storage But why are they not pumping the excess water up to the towoomba dam now that the new pipeline is installed and working

shane

[Tropicaltrout]

Yeah Shane there's another topic in itself, those pipes I read somewhere were built to supply water to the treament plants and arn't allowed to pump directly into each lake?

Well in light of this topic it is a shoe in we will get a lot more wet stuff, I hope the dams like waruma, cainia, BP fill no water for so long out there.

[hkconc]

Annas got no money left to start the pumps up.

[Apollo]

Talking to a bloke who is involved with Paradise. He was telling me that when the dam was nearing full, they opened the gates, but things begun to vibrate uncomfortably, so they reduced them and let the spill take up the work.

[finga]

Leslie is still only 10% full...or is that 90% empty. :(

[rodneyk]

Dont know how true this is but heard thats new pumps arent big enough to pump to Toowoomba ??????? some one may have not got there calculations right:-/

[robersl]

My understanding is thats what this pipelinewas put in for to supply the dam up there when low as the were worried it would not be finished in time before they ran out of water

shane

[Andrew M]

I have read that Wivenhoe has a full capacity of 1.5 milliion ML & a further flood mitigation capacity of 1.45 million ML. Given that sort of flood mitigation capacity it shoul be a while before we loose any Bass over the top.

Cheers Andrew

[Pretzil]

Fun... But yeah I read that Wivenhoe can get to something like 200% capacity before they have to release. I think its something like they control it so they only release during low and runout tides so it doesnt back up and flood brisbane.

[tiges]

Scripps institute in California are usually very accurate with track prediction. Here's their take.

Shane you are starting to talk common sense now and that is against gov policy

[Batters]

bring on the rain! this system could mean the best estuary fishing for years for the next few summers to come. whats wrong with 100's or 1000's of big female barra being released into the rivers? check out townville it is one of the best saltwater fisheries for barra on the east coast and all in the middle of the biggest city in the north, all thanks to the stocking efforts in the freshwater reaches of the ross.

cheers

mick Mick nothing wrong with them being released into the rivers .its getting to the rivers .The fall from the spillway at Awoonga will kill quite a few and to me thats just a waste

3.20am Trev, trouble sleeping, or up to go fishing?

Regarding Leslie dam, did you know they are releasing water for the irrigators downstream. the Northbranch on the Condermine River around brookstead has been running for the past 2 weeks now. Check out the river hights on the BOM site. I suppose, that is what the dam was built for, irrigation downstream.

Yep, I knew that. It's why it was built. For the irrigators not for town supply.
Connolly is for the town and she's chockers virtually.

But it would be nice to see the water up to the boat ramps.
I've been here since '93 and the water has never been above 14% if the old memory serves me okky dokkily.

That reminds me...a kids fishing day at Connelly on the 28th....
