Taking a look at the enlarged Cotter Dam

By johnboy - 15 October 2013 12

cotter dam

With the Tokyo Bureau Chief in town we went for a look at the enlarged cotter dam and the new piece of public art; Flow.

To be honest 15 tonnes of concrete sculpture is a little underwhelming in the context of the entire dam wall.

Blurb or no blurb the dam wall is not going to have its show stolen by any sculpture.

Reading the documentation we discovered there was a path to a lookout over the dam. Having come all this way we thought why not?

It’s a moderately challenging walk and I recommend wearing good shoes.

There’s also a moderately vicious magpie along the way which was a nice “welcome back to Australia” for the Tokyo Bureau Chief.

Once you get up to height it turns out you can see Telstrayama from there. (Which means you should be able to see the dam from Black Mountain now that I think about it)

The warning signs up top were particularly colourful.

Particularly when you look at the wire used on the fence.

Genuine razor wire was, however, found further down.

Once out on the platform is was nice to observe the world’s loneliest staircase.

You could shoot a great science fiction movie on that there dam wall!

On the way down we enjoyed the diligent tagging work done a long way from town.

So it’s worth a look. Cotter Avenue is a picnickers delight, the dam wall is impressive, and it’s a good walk to the lookout.

Impressive, very impressive.

I’ve posted previously that this structure doesn’t look safe. The water behind the wall might put too much pressure on it. From one of the pics it looks like the water is already coming thru the wall. Oh dear.

LOL.
There are pipes travelling through the dam to keep the environmental flows in the river. All dams do leak to one degree or another but that ain’t water coming through the actual dam wall. If you look at it closely the water is coming from the left hand side of the photo into the stilling basin from a pipe.

If the partially completed dam survived the floods of 18 months ago, you don’t think the fully completed dam could put up with the steady pressure it has been designed to withstand?

You make the right side of politics look really stupid, regularly.

I think there should be more productivity from the Tokyo Bureau Chief, in terms of…whatever.

That being said, this is a lovely photographic essay.

Personally, I would just like to see the word ‘water’ on the dam wall in various fonts, and perhaps different languages.

But I am an accredited wanker, and proud of it…(-:

CC is on the money – its a cavitation abatement system to break the flow of the water that would otherwise destroy the wall through cavitation (Google cavitation if youre not lazy)

Is ‘Cotter Avenue’ any good these days? I remember it as having wonderful metal play equipment, a decent strip of grass for french cricket, and a pebbly weir you could walk across . . .

Aeration step – designed to prevent damage to the wall from water flow

Nice pics JB – thanks.

Nice pics – it’s good to know the lookout is now open. According to the signage, there’s supposed to be a picnic area up past the lookout (on the slab where the concrete batching plant was) though it’s pedestrian access only so I can’t see many people dragging their picnic baskets up to it – does anyone know if this is area is open to the public yet?
