31mm and Buller and 14mm at Eildon and no increase in inflow.....very dissappointing

[Trev_n_Ray]

We know they just dream up those figures.... But.... There is very little run-off on my place from this event, we have had less than half the average rainfall for Jan-Feb thus far and the place is very dry, as in a lot of this event is getting soaked up by the ground. It needed it.

Readings taken at 9am Saturday the 18th February 2012

Lake Eildon is at 287.0 mAHD or 1900 mm below full
This is a drop of 30 mm in the past 24 hours
Lake Eildon is currently 92.5% (not 93.9% as I incorrectly posted earlier).

Inflow is approximately 800 Ml/day
Releases are currently 4,500 Ml/day.

Goulburn river release water temp is 11.7 deg

The pondage is currently 42% but may be subject to rapid change

5.2 mm rain for the past 24 hours

[chopper]

Lake Eildon is currently 93.9%

I think that should be 92.5%

[allan]

Bugger 92.5%.

Just looked at my note - I always double check after copying and pasting from an old post, and I see that I've crossed off everything on my slip of paper EXCEPT 92.5% (pencil note after listening to the phone message).

Will edit the post.

I thought there was 8mm yesterday or the day before, at least thats what was registered on the BOM. Oh well... at least the inflows went up. Thanks for the updates!

EDIT: Oh just saw no report today....I should have read that as 8mm:)

Not sure if this is the right section to post this Question ?
Can anyone tell me if there is a set sceduale for when the generate power from the pondage power station ?
I would like to know when the water is NOT flowing from the pondage into the golbourn river.
Any help would be appreciated.

The pondage mini hydro power station operates at ALL times that the release into the river is 1,500 Ml/day or higher.

That is, generally all the time during the irrigation season. They carry out their annual maintenance at a time of year when releases are highly unlikely to exceed 1,500 Ml/day, so as to be available to take advantage of flood releases, pre-releases, environ. releases etc.

The maximum amount of water that the turbine can handle is about 5,000 Ml/day. If the required release is greater than that, then the gates are opened as well (ie. the power station is still operating) to meet the total amount.

Hi Allan,

If running at max outflow (5,000ml/day), do you have any idea at all as to how much power this would add to the Vic/Melb power grid? For instance would it equate to 1% or 2% or any measurable percentage of our total power useage?

I've always been curious about this, so if you or anyone else knows, I would be grateful!!

Hi all, around 2pm yesterday GMW released water down the spillway via the gates for a brief period.
Is this a normal event..

last test on the spillway gates occurred back 12th oct 2011.

I hope their not testing the gates in preparation for major releases considering how full the Lake still is for this time of year!!!!
According to Phlips report this is the first time since the Dam was built that it has remained at over 3,000,000ml for such a long time into summer and also that there has only ever been 4 previous years where the Dam was higher at this time of year!!

Who knows what MGW could have in mind!! Maybe they are thinking that the level "is" too high for this time of year, especially with all the other dams still being at high levels as well!!

The mini-hydro power station has a maximum output of 5 MW. The highest (instantaneous) demand on the Victorian system is from memory around 7 or 8 thousand MW!!!!!!!

Whilst 5 MW is relatively modest, it avoids digging up and burning coal and producing CO2 to that same amount. And it produces power close to the end-user, so neglible loss in the transmission system. (Something like what your roof-mounted solar systems do at only 2 or 3 KW.)

EDIT to add: that the large PS at the base of the dam is 2*60 MW plus 2*7.5 MW (much greater 'fall' or height of water than at the pondage) - still not large compared to the Victorian network; but when the 60 MW turbogenerators went in (1955/56) they were equal largest in the network!
When the 7.5s went in, originally on the old Sugarloaf dam, they were VERY big - early 1930s!
As was the nearby Rubicon scheme at 13 MW in 1926 - which annually produced around 15% of the state's electricity needs. And is still going strong today.

Hi all,does anyone have the INFLOW AND OUTFLOW figures for the THURSDAY 23rd FEB 2012
