A series of maps are available that anticipate River Murray areas at risk of flooding if flows of 80,000 mega litres (ML) a day occur over the coming weeks.
After a long period of drought, the river is receiving increased flows over the South Australian border due to rainfall across the Murray-Darling Basin. The additional flows are providing major environmental benefits , but could also result in some low-lying areas being flooded.
51 maps so far have been produced to show potential risk areas and surrounding floodplains between Morgan to Mannum. This area has been mapped first because of a high number of structures, such as holiday homes, on low-lying areas. Mapping of other areas along the river is being undertaken and will be made available when it is completed.
South Australia is likely to receive a peak flow of 80,000 ML/day in late January to early February and high flows are expected to continue into March. Flows of this level have not been experienced since 1992 and many holiday homes along the river have changed ownership during that time.
A flow at this level does not pose a major risk to towns along the river, but some low-lying areas and floodplains may be at risk. The maps are indicative only and should only be used as a guide for broad scale risk management and planning . They should not be used to draw conclusions about flooding on individual properties.
