The principal thrust of this
This is my review based on official
statistics and documents. It is done in conjunction with Ron McMah, grazier
of Imbil and Trevor Herse, retired of the Gold Coast
Queensland Climate Change Centre of Excellence
This organisation has presented misleading information in the name of "Climate Change". They produced this document that has been picked up in the Queensland Water Commission Water Strategy and now by the Flood Inquiry in its interim report.
This is their initial report that compared the 2001-2007 period with the Federation Drought 1898-1903.
They extended the 2001 to 2007 period to 2009.
Cover of the 2007 publication : Their caveats that they applied.
They pointed out that "rainfall is
not necessarily the best indicator of a hydrological drought". They
did not proceed on that basis "due to lack of material at that distance in
years" There are three points for consideration:
2. The rainfall figures available to all were not researched by this organisation. Very detailed observations and statistics are laid out in Federation drought tab of this website. One will see that the rainfall patterns in the years 1898 to 1903 were thinly spread over the period with inability to create flow whereas the period 2001 to 2007 had at least one summer period that produced an inflow into both dams of 15.6%

3. Rainfall stations in the Wivenhoe/Somerset catchments for the summer period December to March read 99.1% of the long term average for the Wivenhoe and 91.4% for the Somerset. The 20% reduction as listed by QCCCE is in the non-summer months that produce limited inflow.

The extension of the "drought" period to 2009.
This document extends the "drought" by another two years adding years 2008 and 2009. You will notice that it draws on various parts of Queensland that have no relationship to the Wivenhoe/Somerset catchments. It is done to justify their case.
However the Bureau of Meteorology rainfall period 24 months to April 2009 shown here record that the catchments received 125% of the long term average for that period and there was no drought in the catchment for that period being in "decile" 8 to 9 which is "above average".

These substantial inaccurate statements have now been picked up the Queensland Water Commission and the Flood Inquiry. They block research into the solution of Flood proofing Brisbane and Ipswich, mitigating flooding in Gympie and putting real meaning into "drought proofing".
