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.

For the community, the most important message is to stay safe and well-informed. The public can stay updated about flood alerts here:

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

05/01/2022

Due to additional rainfall in the forecast, Snowy Hydro is increasing releases from Jindabyne Dam to the Snowy River from the planned target of 200ML per day, to 3,000ML per day.

These increased releases will reduce the risk of flooding and minimise pressure on communities around and downstream of Lake 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) have been consulted on this plan and continue to work closely with Snowy Hydro to make controlled releases to manage the spill risks and minimise downstream impacts.

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

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.
