Another rising river alert

The NSW Office of Water has issued a 'rising river alert' for the Snowy River between Jindabyne Dam and the Delegate River in southern NSW for yesterday (Wednesday). It relates to the fifth and final high flow spring release that has seen 96.6 gigalitres of environmental water delivered to the Snowy River since early September this year.

The flow rate in the Snowy River below Jindabyne Dam will increase from 579 megalitres per day from midnight 5 November, reaching a peak flow rate equivalent to 3,306 megalitres per day for 8 hours between 8am and 4pm on November 6.

The release will then be scaled back to an equivalent flow rate of 2,177 megalitres per day for the remainder of that day.

The flow rate for the following three days, November 7 to 9, will remain above 1,000 megalitres per day. On Sunday the flow rate will decrease to 965 megalitres per day.

The impact of this release is expected to be greatest immediately below Jindabyne Dam wall, with the effects reducing as the flow moves further down the Snowy River towards the Delegate River.

It is expected to see the river water level at Dalgety rise to 1.36m for eight hours. This rise was expected to occur at approximately midday on November 6 at Dalgety, given the travel time of the water being released from Jindabyne Dam.

Landholders downstream of the Jindabyne Dam are advised to take all necessary precautions with stock, fencing and property.

The NSW Office of Water will work with the NSW State Emergency Service and Bureau of Meteorology to provide information to the community regarding the management of this release should weather conditions warrant.

Three additional smaller high flow pulses will also occur between the end of this November event and Christmas. Following these events the Snowy River will reflect a summer flow pattern.
