The NSW Office of Water has issued a 'rising river alert' for the Snowy River between Jindabyne Dam and Dalgety in southern NSW for today (Tuesday).
The river will rise due to the fourth and largest in a series of five planned environmental releases from Jindabyne Dam to the Snowy River this spring.
The highest flow rate will occur at Jindabyne Dam from 8am to 4pm on Tuesday and will be equivalent to 10,083 megalitres per day for the eight hour period.
For the remainder of Tuesday the flow rate will be equivalent to 4,909 megalitres per day.
The flow rate will drop back to 2,099 megalitres per day on Wednesday.
The environmental changes from this release are expected to be greatest between the dam wall to the junction with the Delegate River. However, the pulse will be noticeable down to the estuary in Victoria.
It is expected to see the river water level at Dalgety rise to 1.85m.
This is the largest of the spring releases, with water released from both the cone valves and over the spill way.
Snowy Hydro Limited has a designated viewing area available from last Saturday to Thursday. The viewing area will be open to the public from 10am to 4pm, and will be accessible from the Jindabyne Tip Road.
It is important to note that water released at Jindabyne will take about four to five 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.
The Office of Water further indicated that while the fourth and largest release is scheduled for October 8, the release will be subject to weather conditions.
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.
