System Block
AN OBSERVATION OF THE CONFLUENCE OF STATISTICAL ABERRATIONS, DAM RATIOS, TIMING AND UNCOMMON RAINFALL EVENTS THAT COMBINED TO HAVE OUR LEADERS DRAW INCORRECT CONCLUSIONS. THEIR INFLUENCE ON ACTIONS TAKEN.

The principal thrust of this website is
FLOOD PROOFING BRISBANE from damaging floods to the point of extinction. MITIGATING flooding in Ipswich and Gympie. Putting REAL MEANING into "Drought proofing SEQ" and ensuring our water supplies by natural means well into the future

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

The current block to the system that needs to be rectified.

8. The volume of water that is available each year from the Wivenhoe/Somerset was set at 449,500ML in year 2002 in SEQWater annual report.
9. As required, the Water resource plan (Moreton) was drafted in 2007. The "High Powered" Technical Advisory Panel recommended that 66% of all water that passes through the system must reach the Brisbane River mouth. I have no problem with that.
10. The problem occurred with the permanent base on which the 66% is calculated. It effectively became 78% by the "clumsy" or alternatively  "clever" definition including all large floods the inclusion of which the Technical Advisory Panel said would "skew" the result.
11. This resulted in a further 160,000ML annually being needlessly diverted to the ecology when applied to the 113 years 1894 to 2006 as an example. This is more than the Traveston proposal could have supplied when fully completed.
12. The available water was reduced from the published 449,500ML to 286,000ML which is approximately the increase in percentages from 66% to 78%.
13. This application was used effectively by Qld Water Infrastructure, the Government sponsored proponent of the proposed Traveston Dam, publically and in their Environmental Impact Study of the Traveston, to block the use of the Borumba Dam expanded citing that no further water could be taken from the Wivenhoe/Somerset system.
