Cotter dam expansion rolls on

I heard that the head of Actew has put his job on the line for both cost and completion dates? That’s a pretty fair indication that the ‘estimates’ are pretty spot on…

and he will get the boot and a huge payout to go with it and say thanks.

Enlarging Cotter is a good Idea its overflowing all the time that dam and also it will make a great fishery. You cant bring water from Tantangara as its in another catchment from Corin and also its used as a top up for the Snowy Mountains Scheme and is usually only around 5% full if that.

The point would be that Corin is being slowly filled as it’s not being used to fill the Cotter and Bendora dams, as they are overflowing with the recent rains.

Extra capacity at the Cotter will mean the ability to hold the water entering the catchment below Corin.

Correct. The 3 dams up that way are one complete system. It is healthy and storage volumes are growing. So enlarging the Cotter makes sense.

Hang on – the festering bucket of mouldy water in my back yard has been full as well – (as long as the dog hasn’t knocked it over again!)

Your point is?????

The post I was replying to said that the Cotter dam wouldn’t fill above 10%. I was pointing out that the water flows in the cotter/Bendora/Corin systems have actually been quite good so I think it will fill. The quality is not an issue.

I’m trying to work out where 27.1 ML (Megalitres) went yesterday being a Sunday and a wet one at that.

Oops. That should read 10.7 ML

FFS – just buy 100GL from Tatangara and let it flow down to Corin, and then pump it across to Googong. I’m getting sick of hearing the neighbours whinging when I hose my driveway.

Is there 100GL in Tantangara?

Actually if you look at the dam stats you will see the Cotter and Bendora dams have been 100% full for some time. Now considering these are being topped up by Corin which has reminded static I would say that the catchment in this area is healthy, so will rise and fill the enlarged Cotter over time.

Water can’t flow from Tantangara to Corin, unless we built a pipeline to connect them. Water released from Tantangara flows down the Murrumbidgee.

There is a seperate project building a weir on the Murrumbidgee at Angle Crossing, together with a pumping station and a pipeline to Googong, that when complete will allow water to be pumped from the Murrumbidgee to Googong (and so also allow us to purchase Tantangara water, if we wanted to).

Ah yes – but will the “water conservation measures” (the word ‘restriction’ is no longer used) ever be lifted?

I am prepared to bet a large chunk of hard earned that we will continue to be restricted in how we use the water we pay for.

Yes we are going to fund the new dam wall, yes it should ‘secure our water needs’ but no promise that we’ll be acually free to decide how and when we use it after paying for it.
