Good to see other people are noticing the pathetic standard of BoM attempts to model rainfall 90 days out in their three month Outlooks.
Scroll well down on this article at: www.stockinterview.com/News/03092007/Ranger-Flooded-ERA.html
under the Australian rainfall map for
“On February 22nd, the Australian Government’s Bureau of Meteorology issued a “Neutral” three-month outlook for the country’s Northern Territories, writing, “The Northern Territory outlook for total March to May rainfall shows no strong swings in the odds toward wetter or drier conditions.” A few days later, one of the world’s largest producing uranium mines shut down because of heavy rainfall and flooding, ..etc”
The BoM prediction/forecast, whatever, could not hold for a week. Readers here may have seen my critique of years of failed BoM rainfall Outlooks at: www.warwickhughes.com/drought/ which could do with updating.
Premier Peter Beattie and his Deputy Premier Anna Bligh are whining in concert that the Federal Government is not doing enough to assist drought-stricken Queenslanders.
Within the last ten years the Queensland Govt. stood by and let Cubbie Station trap river flows at the border with NSW up to a scale of 600 GL per year (MDBC), about equal to the annual water consumption in Sydney.

Recent news items copied below record the discovery of a 140 million year old trapdoor spider species in the SW of Western Australia. If is fascinating to read carefully the words from the Department of Environment and Conservation and ponder how they reveal exactly how Dark Green policy is formed that will impinge irrationally on the States population.
Here is a species that has survived since before the dinosaurs and in just the last million years has coped with four global ice ages, involving repeated climate changes through times that were most certainly, hotter than now, colder than now, wetter than now and dryer than now. Not to mention tens of thousands of years subjected to indigenous forest burning customs, followed by over a century of european logging.

Finally got around to assembling a rain history for the Brisbane River catchments. More to say at the above link.
This is the graphic.
I have more to say at the above link.
So much still to be discovered.
Perth uses approximately 300GL of water PA.
The Govt. is constructing a ~$400Mill seawater desalination plant to produce 45GL PA.
In 2005 May to October (the runoff season) Perth dam catchments which total 3500 squ. kms had circa 958mm of rain. This equates to about 3353GL water falling free into catchments of which approx. 115GL flowed into dams, meaning that catchment efficiency (yield) was 3.4%.
My graphic at the Perth Water Users web site shows that up until the mid 1990’s catchment efficiency was 5.5 to 6%. Let’s just assume for a minute that our Governments had been sensible and maintained catchment management work, keeping yields this year at say 5.7%. An increase of 2.3% (5.7-3.4) in this years yield would have put an extra 75+ GL (2.3% of 3353 GL) into our dams, which is 160% of the projected production from the Kwinana Desalination Plant (KDP), where costs have already blown out to over $387Million.
