WaterNSW raising releases to lower storage ahead of rain

16 November 2021

WaterNSW is increasing release rates from Burrinjuck Dam to lower the storage level to capture inflows from a rain event forecast for the weekend.

Following weather advice from the Bureau of Meteorology and in consultation with the Murrumbidgee Airspace Reference Panel, releases from Burrinjuck will increase to a rate of ~32 gigalitres per day (GL/day) this afternoon.

Burrinjuck Dam currently sits at 99% of storage capacity, having risen from 92% last week after receiving 131GL of inflow in four days from rainfall last week.

While the increased releases will keep river levels well below minor flood level, low-lying areas around Gundagai and Collingullie may experience some inundation. Landholders in these areas should monitor river heights and take precautions with stock and equipment.

Blowering Dam sits at 98% of capacity with 36GL of storage capacity, and a decision will be made this week as to release requirements to achieve a target of 40GL in available airspace.

WaterNSW is monitoring the situation and consulting the Murrumbidgee Airspace Reference Panel which includes the NSW State Emergency Service, local councils in the Murrumbidgee, irrigators, landholders and other key stakeholders.

WaterNSW Executive Manager of System Operations, Adrian Langdon said based on weather forecasts from the Bureau of Meteorology and in consultation with local airspace advisory panels, WaterNSW has already released large volumes from dams in flood-prone river valleys.

With the Bureau of Meteorology continuing to forecast a climate outlook that “indicates rainfall over the coming months is likely to be above average” WaterNSW will continue to make airspace releases as required.
