No not the Gordon below Franklin dam - that wasn't built. This dam on the Gordon River really started all the controversy and kicked off the Green movement in Australia when it flooded the natural Lake Pedder.

There had to be some pretty smart engineering go into this wall it is all curves in 3 dimensions. Completed in 1974 a lot of the design work would have been done with slide rules. Maybe in the end the commission had access to some sort of prehistoric computer but there would not have been any sophisticated computer modelling of today.

It is a bloody long way down there.

Gordon Dam.

There is a Hydro station here but it is completely underground. It is even deeper than the bottom of the dam. The tailings race empties into the Gordon River further downstream where it is lower.
