Merv, When they refer to the current water volume of Wivenhoe it is a percentage of that level designed for drinking water.

ie. At 100% the dam holds 1,160,000 ML of water for drinking purposes, but has a further capacity of 1.45 million megalitres of additional water for flood mitigation which is not taken to account in the 100%.

The flood water will then released so that when it reaches Brisbane, the flow will coincide with an outgoing tide, thus reducing flood peaks in the City.

On the Morning of 21st May the dam was reported to be at 55.67% holding some 648653ML of water.

I would start worrying when they are reporting 200% (2,320,000ML) capacity as that would be approaching the designed total capacity of 2,610,000ML.

I have met some engineers who I would not trust to design a swimming pool let alone a dam of that capacity.
