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:
