WaterNSW dams to capture rain event inflows without spill

WaterNSW dams to capture rain event inflows without spill

01 December 2017

WaterNSW dams will capture any run-off generated by a major weather event forecast to occur in coming days over the central and southern regions of NSW.

WaterNSW is working closely with the NSW Bureau of Meteorology (BoM) to monitor what is anticipated to be a significant rainfall episode, expected to peak on Saturday.

Those dams most likely to be affected all have considerable storage capacity to absorb inflows without spilling. Water releases from dams in the vicinity have been scaled back as a precaution.

On current information the dams most likely to be impacted are:

  • Hume on the Murray River (75% of storage capacity)
  • Burrinjuck (62%) on the Murrumbidgee
  • Blowering (55%) on the Tumut
  • Wyangala (78%) on the Lachlan.

While the BoM is forecasting heavy falls across the central and southern regions of NSW – and heavier falls in Victoria – the dry catchment conditions mean that approximately 40mm of rain must occur before run-off commences. The forecast rainfall is likely to result in some good inflows into the southern storages over the coming weeks.

Rain projections indicate that flooding in these regions will occur downstream of the dams, and landholders should remain vigilant and take precautions to protect stock and equipment.

The increased flows downstream of the dams are likely to trigger a supplementary event for irrigators over the weekend and during next week.
