Woronora Dam is only 10.8 km to the South West of where I live – but its location in the centre of Heathcote National Park meant I had to drive an astonishing 63 km via Appin and Helensburgh just to get there!
The dam holds 285,000 cubic metres of water and was constructed between 1927 and 1941 and supplies water to the Sydney southern suburbs. It is 390 metres long.
At the end of this post are a couple of images I had taken from the dam on my previous visit in 1970.
The pontoons in the main reservoir are used by Maritime Operations Division within the Australian Department of Defence to test its sonar facilities, according to an entry in Wikipedia.
The above image is a modern replica of the following historical image which I took from exacly the same spot over forty-four years earlier, just two months after my arrival in Australia as a migrant from England.
I took a second image that day:
Both of the 1970 images have been partially restored but some of the noise on the print after forty-four years was just too much to eradicate.
Finally an image that is hardly one of my best but stretching my camera out over the 66 metre abyss below and trying to keep it level proved too much for me. These are the stairs down from the top of the dam to the river bed below:
