Today’s River Murray flow update shows the floodwater peak is still due in Renmark around the end of December and forecasts remain between 190 and 220 gigalitres a day, consistent with previous projections.
While flow rates are useful for forecasting the scale of floods, water heights provide a better picture of conditions on the ground. Subsequently, as we are now closer to the expected peak, the Department for Environment and Water is now able to provide daily height forecasts for population centres.
As the peak moves closer to the South Australian border, DEW is now in a better position to forecast when peak water levels are expected to arrive at different locations along the river and this information will be made available www.sa.gov.au
Effective from today, the peak is expected in Renmark between 24-31 December, in Berri between 25 December and 5 January, in Waikerie between 1-12 January, in Swan Reach between 5-16 January and Murray Bridge between 6-17 January.
River communities should consider this as part of their flood emergency preparedness and factor in potential road and ferry closures, disruptions to the power network and reduced services.
Overnight, the SES issued an emergency message for Walker Flat after floodwaters threatened to isolate the town. There are also current Watch and Act message for Caurnamont, Purnong and Bowhill.
