Wolffdene dam
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

1.The Wolffdene Dam cancellation assurances not met

Wolffdene Dam.jpg (145784 bytes)Extract from the Ministerial Statement by Hon. E. D. Casey (Mackay-Minister for Primary Industries) ALP member. Statement was made on the 1st March 1990 setting out the reason for the cancellation of the Wolffdene Dam.

He had this to say on future water supplies: "On present indications, an additional source of supply is unlikely to be required before the year 2010. However, it is recognised that the actual timing will depend very much on future population growth in the South East Urban corridors."

"Adequate time is available to properly plan to meet those water needs. The people of Brisbane and surrounding areas can be assured that the Goss Government (ALP) has such planning well in hand."

Obviously, this assurance made on behalf of the Government, was not met! Two years later in 1992 it was clear that normal summer rainfall was inadequate for our needs and that the Wivenhoe/Somerset dams were reliant on random "low pressure systems" to fill them as explained in the leader to this page. 

Much larger dam space is needed to control them for the Ecology and our use. This website recommends enlargement of the Borumba Dam and connection to the Wivenhoe/Somerset Dams. 

Partial correction of the oversight has unnecessarily cost us billions of dollars so far. It is fair to say that a backup water supply in the Wolffdene Dam would have permitted prior reduction in our water supply to counter the 2011 flood thus reducing the damage to our citizens of SEQ. 

The 2011 flood was true to form. The saturation rains of "low pressure systems" had filled our dams by March 2010. This is well before the weather pattern of two major "low pressure systems" had set in and the Wolffdene Dam, like the Wivenhoe and Somerset dams, would have been full.

The "drought" excuse was used for non-compliance to the assurance which leads to:-
