Rising river alert - Snowy river below Jindabyne dam - September
Media release | 24 August 2020
The NSW Department of Planning, Industry and Environment today issued a ‘rising river alert’ for the Snowy River between Jindabyne Dam and Dalgety in southern NSW for Thursday 3 September 2020.
The river will rise due to the third high-flow event in a series of four planned environmental releases from Jindabyne Dam to the Snowy River during winter and spring 2020.
The highest flow rate will occur at Jindabyne Dam from 8am to 4pm on Thursday 3 September 2020 and will be equivalent to 4,500 megalitres per day for the eight hour period.
It is expected to see the river level at Dalgety rise from 1.0m to 1.49m, a rise of 0.49m, however; higher river levels can eventuate from local rainfall. Weather conditions will be closely monitored and the release reduced or postponed if necessary to avoid impacting natural river levels.
For the remainder of Thursday 3 September, the flow rate will be about 1,970 megalitres per day. The flow rate will drop back to a target of about 1,200 megalitres per day on Friday 4 September.
The environmental benefits from this release are expected to be greatest between the dam wall and the junction with the Delegate River. However, the flow pulse will be noticeable well down into Victoria.
Water released at Jindabyne will take about six hours to reach Dalgety Weir at this flow rate. Landholders downstream of the Jindabyne Dam are advised to take all necessary precautions with stock, fencing and property in proximity to the river.
The department will work with the NSW State Emergency Service and the Bureau of Meteorology to provide information to the community regarding the management of this release should weather conditions warrant.
Conditions will be closely monitored in the lead up to the release. If heavy rainfall appears likely the release will be reduced or postponed to avoid any impact on natural river levels and an announcement will be made accordingly.
