JINDABYNE LAKE LEVELS – Updated 21 March 2022

21/03/2022

High inflows to the Snowy Scheme, including Jindabyne catchment, have continued through March.

As the lake level at Jindabyne approached 100% on 7 March, additional releases were made to the Snowy River below Jindabyne Dam to manage the high inflows. These release have now tapered off, and will again follow the environmental release targets notified here: https://www.snowyhydro.com.au/about/reports/

The outlook as we head towards winter is for wet conditions to continue. Snowy Hydro will continue to pump water from Jindabyne to Geehi to be released through Murray 1 and 2 Power stations into the upper Murray River at every opportunity. Further releases to the Snowy River may still be required to avoid uncontrolled releases.

If Lake Jindabyne reaches 100%, it will trigger operation of the spillway gates. Dam safety is paramount at this time and the spillway gates will automatically release water at any time the storage reaches or exceeds 100%.
For the community, the most important message is to stay safe and well-informed. The public can stay updated about flood alerts here:

JINDABYNE LAKE LEVELS

07/03/2022

Wet conditions have persisted through summer and are now continuing into autumn. Snowy Hydro has been pumping water out of the Jindabyne catchment at every opportunity and gradually created a significant amount of reservoir airspace considering the conditions.

Heavy rainfall on Saturday has triggered high inflows to Jindabyne Dam and with a forecast for lingering showers and potential for further heavy rain next week, additional releases will be required from Jindabyne Dam to the Snowy River.

Snowy Hydro commenced making additional releases into the Snowy River below Jindabyne storage today on Monday 7 March. These releases will be greater than the environmental releases notified on Snowy Hydro’s website and may change at short notice in response to the weather conditions. Releases could reach flow rates up to 3,000 megalitres per day, similar to the rates that were released in late December 2021 and early January 2022. Releases are expected to continue at these elevated rates for the next week or until Jindabyne dam levels can be lowered.

If Lake Jindabyne reaches 100%, it will trigger operation of the spillway gates. Dam safety is paramount at this time and the spillway gates will automatically release water at any time the storage reaches or exceeds 100%.

NSW Department of Planning and Environment (DPE Water) has been consulted on this plan and continues to work closely with Snowy Hydro to make controlled releases to manage the spill risks and minimise downstream impacts.

UPDATED: JINDABYNE LAKE LEVELS

24/01/2022

December 2021 was officially the wettest since records began for the Lake Jindabyne catchment and with over 160mm of rain so far, January isn’t too far behind. The lake level will continue to stay high throughout summer. 

Releases from Jindabyne Dam to the Snowy River returned to the advised environmental releases from 18 January. Additional flows above the notified environmental releases into the Snowy River are possible while wet conditions persist. Snowy Hydro will continue to look for opportunities to pump water to Geehi Reservoir, however, at times, the surplus of water pumped to Geehi will be returned to Jindabyne.

It remains possible that the storage may again reach 100% (or full supply level), triggering operation of the spillway gates. Dam safety is paramount at this time and the spillway gates will automatically release water at any time the storage reaches or exceeds 100%.

NSW Department of Planning, Industry and Environment (DPIE Water) has been consulted on this plan and continues to work closely with Snowy Hydro to make controlled releases to manage the spill risks and minimise downstream impacts.

UPDATED: JINDABYNE LAKE LEVELS

11/01/2022

December 2021 was officially the wettest since records began for the Lake Jindabyne catchment. The lake level will continue to stay high throughout summer. 

Daily water releases from the lake of up to 3,000 megalitres (ML) per day will continue until at least 17 January. It is likely that additional flows above the notified environmental releases will continue down the Snowy River while wet conditions persist. Snowy Hydro will continue to look for opportunities to pump water to Geehi Reservoir, however, at times, the surplus of water pumped to Geehi will be returned to Jindabyne.

It remains possible that the storage may again reach 100% (or full supply level), triggering operation of the spillway gates. Dam safety is paramount at this time and the spillway gates will automatically release water at any time the storage reaches or exceeds 100%.

UPDATED: JINDABYNE DAM SPILL

22/12/2021

Following recent significant rainfall events, Jindabyne Dam reached full supply level on Monday 20 December and commenced spilling into the Snowy River.

Up to 140mm of rain was recorded in Snowy Scheme catchments last weekend, continuing what has been a very wet year and the wettest November/December since 1992.

With further storm activity forecast for the Christmas weekend and limited opportunities to pump water from Lake Jindabyne into the Murray River catchment, Snowy Hydro has reached agreement with NSW Department of Planning, Industry and Environment (DPIE Water) to increase releases from the dam to bring the lake below full supply level. However, it is possible that the spillway may operate again if further extreme rainfall is experienced.

Upcoming releases from Jindabyne Dam into the Snowy River:

On Wednesday 22 December, the river will have a daily flow rate of 4,092 megalitres per day over a 24-hour period. According to DPIE (Water), this will result in a highest peak of 1.45m at Dalgety Weir. 

On Thursday 23 December, the river will have a daily flow rate of 5,000 megalitres per day over a 24-hour period. According to DPIE (Water), this will result in a highest peak of 1.51m at Dalgety Weir. 

On Friday 24 December, the river will have a daily flow rate of 4,866 megalitres per day over a 24-hour period. According to DPIE (Water), this will result in a highest peak of 1.50m at Dalgety Weir. 

On Saturday 25 December, the river will have a daily flow rate of 2,387 megalitres per day over a 24-hour period. According to DPIE (Water), this will result in a highest peak of 1.50m at Dalgety Weir. 

Snowy Hydro will continue to work closely with DPIE Water to identify opportunities to make controlled releases to manage the spill risks and minimise downstream impacts. Dam safety is paramount at this time and the spillway gates will automatically release water at any time the storage reaches or exceeds 100%.

Lake levels are anticipated to remain high for at least the next month, with continuing wet weather predicted in the seasonal outlook.

JINDABYNE DAM SPILL

20/12/2021

Following recent significant rainfall events, Jindabyne Dam reached full supply level (FSL) today and commenced spilling into the Snowy River this morning.

Up to 140mm of rain was recorded in Snowy Scheme catchments over the weekend, continuing what has been a very wet year and the wettest November/December since 1992.

The spillway is likely to continue to operate intermittently for the next few days and Lake Jindabyne will remain very close to FSL this week.

With further storm activity forecast for the Christmas weekend and limited opportunities to pump water from Lake Jindabyne into the Murray River catchment, it is expected the spillway may operate again by the end of the week.

Snowy Hydro is working closely with NSW Department of Planning, Industry and Environment (Water) to identify opportunities to make controlled releases and manage downstream impacts. Dam safety is paramount at this time and the spillway gates will automatically release water to return the storage to 100%.

Lake levels are anticipated to remain high for at least the next month, with continuing wet weather predicted in the seasonal outlook.

National Heritage Listing for the Snowy Scheme

14/10/2016

The Snowy Mountains Scheme has today been honoured with inclusion on the National Heritage List. As the biggest industrial development Australia has ever attempted, the Snowy Mountains Scheme changed the face of Australia.

Constructed between 1949 and 1974, the Snowy Mountains Scheme is the largest public works engineering scheme ever undertaken in Australia. Made up of 225 kilometres of tunnels, pipelines and aqueducts, sixteen major dams, nine power stations and a pumping station, the entire Scheme covers a mountainous area of 5124 square kilometres in southern New South Wales. Only two per cent of the entire construction is visible above the ground.

The Scheme’s dams, tunnels, aqueducts and power stations, including some buried deep underground, are some of the most complex and technical engineering and construction feats in the country and the world. Significant engineering advancements were achieved during the construction of the Scheme, including rockbolting and the use of 330 kV transmission lines. Remarkably, the Scheme was completed on time and on budget.

Over 100,000 people from more than 30 countries worked on the Snowy Mountains Scheme. Seventy per cent of these were migrants displaced from their homes in Europe during the Second World War. These workers and their children lived in towns and camps across the Snowy Mountains during construction. While many of these people moved on after completing their work, the Scheme still holds a special significance for workers, their descendants and the wider community as a symbol of multicultural Australia. Cooma’s annual multicultural festival continues to showcase the diversity of cultures in the region.

“The Scheme’s inclusion on the National Heritage List formalises the important chapter the Snowy Scheme has in the Australian story and cements our place in the nation’s history,” said Snowy Hydro Limited Chief Executive Officer Paul Broad.

“Snowy Hydro continues to be an important part of the social fabric of the communities we operate in and we continue to be linked with the Snowy Mountains communities that we helped build. While we have evolved to become a dynamic and growing energy company, the heart of our operations continues to be the Snowy Mountains region.”

The Snowy Mountains Scheme is an audacious and brilliant example of modern Australia—a bold idea brought to life by the hard-work of thousands of people coming to Australia from all over the world.

The Snowy Mountains Scheme remains one of Australia’s largest producers of renewable energy, including nearly a third of renewable energy fed into the eastern mainland grid, and manages water flows for over $3 billion in agricultural produce.

The Snowy Mountains Scheme is the 107th place added to Australia’s National Heritage List. For more details see www.environment.gov.au/ heritage/places/national/snowy-mountains-scheme

One of the wettest winters on record

12/09/2016

Our weather specialists have been busy monitoring and forecasting the interesting weather patterns that have occurred over the Snowy Mountains region to date in 2016.

The dramatic turn of climate conditions from very dry to very wet has eventuated largely as we were forecasting earlier in the year. Conditions have turned from one of the driest summers on record to one of the wettest autumn/winters on record. This has included some significant inflow events such as around 22 July when we saw the average inflows for the Scheme for the month of July occur in one week alone.

For the statisticians, inflows are now tracking at roughly a 9 per cent probability of exceedance, meaning that we would only expect nine in every 100 years to be wetter. With only four months of the water year passed, we have received well over half of our annual inflows.

As well as the constant and careful management of diversions and forced generation that these very wet conditions require within the Scheme, we are also working closely with stakeholders downstream to make sure key information is exchanged and there are no surprises. This includes the water authorities of NSW Department of Primary Industries – Water, Water NSW and the Murray Darling Basin Authority who operate the major storages downstream of us, as well as our local communities who live and work in an around the Snowy Scheme.

There is still a healthy snowpack on the hill so we are planning for continued wet conditions for spring and early summer which will keep our people and assets on their toes and doing what they do best. The outlook into summer is less certain, but with such a wet catchment we are not expecting things to turn dry any time soon!

Experiencing wet conditions

07/09/2016

What a difference a couple of months make! Earlier in the year we were preparing for drier conditions off the back of El Nino but, as our Snowy Hydro climate scientists predicted last edition, we are now experiencing decidedly wetter conditions. With only four months of the water year passed, we have already received well over half of our annual inflows and the snowpack hasn’t started to melt yet. Already we have seen some high inflow events in July which affected landholders around the Murray; and NSW water authorities are carefully watching the Murrumbidgee side to manage any water issues that could arise there.

Snowy Hydro is working with local emergency services and property owners to ensure the lines of communication are open and we update people regularly on the conditions we are experiencing on the waterways across our operations. As the snow melts and inflows into the Scheme increase, it’s important local communities and landholders are kept abreast of any major movements of water. We will continue to work with local authorities and communities in the coming months to carefully manage any water events as they arise.

On a pleasing note, Snowy Hydro has ended the 2015/16 financial year in a strong position. This is the first full year that our recent acquisitions – our gas power station in Colongra and diesel assets in South Australia, as well as Lumo Energy and Direct Connect – have contributed to our financial results.

We hit some significant milestones as a business this year – exceeding more than $2 billion in revenue and passing the one million retail customer mark – a position we have sustained and continue to grow. Our retail businesses – Red Energy, Lumo Energy and Direct Connect – are all working together to attract and retain customers, focusing on superior customer service and industry leading customer satisfaction scores. We have more than 1200 staff working in our retail businesses in Melbourne and we are working to bring them all together under one roof by next year.

Our generation business has also had a strong year. Generation levels have increased as market and operational conditions improved. We are focused on improving the performance of our assets across the fleet and are currently working on a major upgrade of one of the units at Murray 1 in Khancoban, meaning more Snowy Hydro workers will be located in and around that region over the coming months.

We would love to grow support for Red Energy in the Snowy Mountains and, as such, we have been sponsoring local events and festivals and we’re once again sponsoring the ski season this Winter. As a local company with such a long and proud history in the Snowy Mountains, we want to ensure that the communities we live and work in can get the benefit of being our customers, with energy backed by the mighty Snowy Scheme. Our field sales teams have been out and about in the Cooma and Tumut regions over the last few months and will continue to encourage households and businesses to get on board with Red.

Shortly we will be conducting our biennial community research so you may receive a phone call asking you to spend some time talking about Snowy Hydro, how we communicate with you and your understanding of our business and its challenges. If you are approached, we would greatly appreciate you spending the time to give us your thoughts. It’s all confidential and anonymous, of course. It will help us to ensure we are doing the right things to keep you informed about our business. In the meantime, stay safe and dry!
