Thought I would start a thread on water storage levels as we head into the warmer months.

Dam storage levels are very low around my area & several towns that rely on them for water are heading for some harsh restrictions if we do not get decent rainfall soon. Coming into the summer cropping season the amount of water available for irrigation will be minimal & the effect on the local economy of these towns will be affected, possibly leading to job losses.

Dam storage levels from around my area:

Gwydir Valley
Copeton Dam - nearly three times as large as Sydney Harbour.
Currently at 8.6% (134,701 ml of 1,364,000 megalitres) Irrigation & water supply for Inverell, population 11,000.

Namoi Valley
Keepit Dam - nearly as large as Sydney Harbour.
Currently at 0.9% (10,621 ml of 425,000 megalitres) Mainly used for irrigation.

Splitrock Dam - three-quarters the volume of Sydney Harbour.
Currently at 1.9% (10,638 ml of 397,370 megalitres) Back up for Keepit & water supply for 1,410 people.

Chaffey Dam - 40,000 Olympic Pools.
Currently at 20.7% (23,188 ml of 100,500 megalitres) Mainly for the city of Tamworth with a population of 45,000

Tamworth are currently on Level 4 restrictions & I think the trigger point for Level 5 is 20%. Many other towns are out of water & are relying on water being trucked in.
Luckily my home town does not have any restrictions at the moment as there was a pipeline constructed from Splitrock Dam around 8 years ago, but this could change if the drought persists.

YTD - MAX 42.2 Jan 16 (record) MIN -7.1 June 22 Rainfall 99.0 mm

Great thread Ambient. Gee, I didn't realise it was that bad. I know from the news it says it is dry and that there are x amount of drought regions etc, but until you see the numbers like that it makes it easy to understand the future and not just the current situation. I guess it will take more than a bit of rain to increase them too, because the land is so dry it will soak up a huge amount before there is any run off.

Fingers crossed for some rain.

Thanks ambient. An extremely important topic that l will surely follow..


I had NO idea things were that bad for dams out your way or in fact any place.Crying I rarely pay attention to such things.

Found this BOM info that l never knew existed.

http://www.bom.gov.au/wa...014&productType=FC_7

I don't think we would be surprised at this 3 month forecast.

If l am reading that right , l believe the graph is saying inflows will be about one fifth , or 70-80% less inflow than normal of normal ( historical reference) for this time period?

I think the restrictions will get worse you would think.

The ground is very hydrophobic at the moment so any heavy rain is just going to run off. I can see a flood event coming when the drought eventually breaks, will be good for the impoundments but will cause a lot of erosion.

Thanks for that link SB, will add it to my reference material. Checked the forecast for the Upper Namoi & it looks about the same. Most of the rivers would have the same outlook I would expect.

Front page of Sunday Telegraph.. September 15th 2019

DAY ZERO
Doomsday countdown reveals major towns tomrun dry on weeks..

My my ! What papers will do to sell papers. Drama, drama . Same with TV. None the less l succumbed and bought the darn thing today.

Actually. I think it is a good thing. The radio talk back John laws channel and social media were on to this today.Big time.

Some great discussion about adaptability and making our country drought proof. I think some good will come of this.

quote

"Dubbo will be dry in November unless there is major rainfall" -Page one

There is a double page spread on all the day zeros for major catchments. There is too much to go through the lot but might pick away at it in the coming weeks.

Anyway. Radio talk had the Dubbo major on this morning . He assured all residents they would have drinking and shower water.RollEyes

Great business for water rank manufacturers. Maybe a good thing. Independence is a wonderful thing

Dubbo is on level 2 restrictions and gets 70% of its water from the Macquarie river and 30% from bores and the major said they catch storm water run off for garden watering .

So all eyes on the Macquarie river catchment in the coming months.

Actually an informative double page on the state of our water supply. I think it was worth the $3 for the paper , just for this very handy bit of research

I read the news today and l believe some parts of the country are doing tuff in regards to water supply.Sad

I have to say l have never paid attention to the Gladstone water supply. In fact l know nothing about it. Generally take it all for granted.

I went on to the council site to see if there were restrictionsBlushing

and the good news is



Water restrictions

For consumers within the Gladstone Regional Council local government area there are currently no water restrictions. Council would only impose restrictions when circumstances change, and restrictions are required.

There is lots of talk on TV and other media about water shortage.

Tamworth apparently is a problem but how bad is a bit hazy

https://www.northerndail...tion-for-tamworth/?cs=12

Tamworth water supply: WaterNSW report suggests Tamworth could run out by June 2020

but then

the major says something different. So you just don't now really. I don't live there but l wonder what the residents think?

Is there a problem or not..?Quite a mish mash really'Tamworth water supply: WaterNSW report suggests Tamworth could run out by June 2020

Council to fight for extra water from Chaffey Dam
Level 5 restrictions to be introduced early for Tamworth
Dam shame: councillor claims 500 days of water lost

But Col Murray said it was too early to be making predictions on a day zero for Tamworth and the city "was not that close" to running dry.

Cr Murray said there would be more certainty about the longevity of the city's remaining supply by the end of the summer.

"We're not sure what the losses will be without any irrigation from surface water," he said.

"We're not sure what the losses will be with water drawn from the aquifer for groundwater irrigation.

"We're doing our best to try and get the longest possible time out the water that is left."

The state government is believed to be working double time to get the Chaffey to Dungowan pipeline built by March 2020.

The pipeline has been seen as a solution to "transmission loss" which meant the council was requesting a release from Chaffey Dam almost double what was needed to service the city.

Cr Murray believed the pipeline would give the city more certainty and had bought more time.

"We would have definitely run out next year if the actions proposed weren't taken," he said.

The state government recently pledged $39 million to build the pipeline which was seen as an emergency measure to see the city through the drought.

But it appears there is still no certainty on a long term water security project.

An expansion to Dungowan Dam has firmed as the best option for Tamworth.

"That rests with the other levels of government and their capacity to fund it, local government simply does not have that capacity," he said.

Deputy premier John Barilaro said the state needed to start building dams sooner and suggested easing planning requirements and community consultation on the process.

Six months after Murrurundi's water ran out, the New South Wales Upper Hunter community struggles to survive on extreme, level-six water restrictions, in a grim prediction of the future for other country towns facing their own impending water crisis as the drought continues.

Every day, Murrurundi's water supply must be carted in via a convoy of water trucks from Scone, a costly exercise for the local council.

But residents told 7.30 they did not drink the supplied town water, and were mulling over their future in the town if nothing improved after the council's pipeline comes online in 2020.

Pictures comparing upstream of Dubbo in 2017 and 2019.

Did it really only take 2 years to empty this?
