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%.

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.

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