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

Alcohol doesn't agree with me, but i sure do enjoy the argument!!!
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.
i have a trip planned to mondy this weekend so it can stay as far away as possible as far as im concerned....
No love its not new...i've had that reel for ages
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
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?????
cheers Steve
I dont have ADHD......ohh look a squirrell !!!
Wyvenhoe was initially built as Flood mitigation.
I hope they have opened the gate.
You cannot stop a flood with a full dam!
Most of my Money is spent on Booze and Fishin.The Rest is just Wasted!
To The Shed.............
But isn't it classed as being full at 50 to 60% capacity.????

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.
Jack.
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
