Wow - how much extra would that Warragamba catchment cover if it was raised fifty feet? Anyone provided a map yet?

Apparently not only is 'global warming' causing the oceans to rise, but the dams as well.. buggar me! We might see a flooded for good Lake Eyre yet.... open it up to the sea and install the GAIA Phase I..... we'll forcefully remove the Eyrian Mud Kipper and the Saltbush Striped Sloth to a better environment so they won't become extinct.

Put all those boat people to digging the canal from Port Pirie or whatever....

Or increased water requirements based on increased population growth, that would be fools talk.

A good contour map of the district would show how much extra land would be taken up by the 50 feet. 16 metrres

Wow! You must be a denier-scientist. Mixing imperial and metric measures and no evidence for your claim.

50 feet equals 15.24 metres. Close to 16 metres.

No evidence of what? Raising a dam wall 50 feet could raise the water behind the dam, up to a 50 foot (15.24m) higher contour line? You really disagree with that statement?

Sorry Darling. Wrong again. A prudent man would take into account wave height which might mean the dam could not be filled to 15.24 metres and definitely not 16 metres.

As chief protagonist of a 15.24 metre erection, what would be the effect of an earthquake?

Raising the dam wall won't stop a catastrophic weather event .............. mother nature always bests that

it will destroy even more environment for wildlife by flooding more land or property

it will more likely probably benefit a private enterprise water company by increasing the volume they can sell

And from what I can see the natural sides ...especially the southern side wouldn't support a 46 foot increase in the height.

Warragamba is now in an earthquake zone? DamN. Wink

They would fill to the height of the spillway. That is how they are designed.

I know that - which is why I raised the question... and the next question is:- Is Baird talking through his hat? Some homes may disappear under an extra fifty feet of water... allowing for a spillway at the top....

You don't get it. Waves!

I am awarding you an F in dam design.

'The spillway:

prevents dambreak in extreme floods
protects Sydney's major water supply
reduces risk of dambreak flooding
reduces potential flood levels at Windsor by up to four metres
is the most practical and cost-effective way to increase flood handling capacity
enables the dam to fully comply with modern dam safety standards.'

'In the event of an extreme flood, five erodible earth and clay walls or 'fuse plugs' built across the upstream opening of the auxiliary spillway would progressively wash away by the rising floodwaters. The auxiliary spillway would then divert excess floodwater around the dam. The 'flip bucket' at the downstream end of the auxiliary spillway manages the floodwaters entering the river at the point where they meet the flow from the central spillway. This dissipates the water's energy and minimises erosion of the riverbed and banks.'

http://www.waternsw.com.au/supply/Greater-Sydney/safety/warragamba-dam-auxiliary...

No mention of waves there.

To increase the height of the dam wall they are going to have replace those 5 erodible plugs.
