It seems, deliberating the syphoning testifies perfectly to a very context of my posts because, according to Collinsett 's post on 4 Feb-07, "...let the seawater trickle downhill into lake Eyre, as it is below sea level".

I agree with geek100's assessment on the 'lift limits', but not totally convinced yet - that it is an impractical proposition.
If the syphon 'lift' was kept to a maximum of say 6 to 7 metres a substantial proportion of the distance from Port Augusta to Lake Eyre South can be easily accommodated with a pipe laid in along the edge of Lake Torrens (about 7 metres AHD). Question - What is the minimum height profile from Lake Torrens to Lake Eyre South?
That would determine whether it would be practical to 'trench in' or tunnel a syphoning pipe right through.

frostyinferno,

What has got a rooster to a wind-pointer?

I would very much appreciate your priceless on technical/engineering merits attending to my question.

For MichaelK,
It is a 'weather cock' - cock head - points to the wind!

Already ostracised here, I try avoiding any ambiguity of which cock-words are.

Thank you for eventually broadening your understanding with issue.
