The latest River Murray flow update shows the peak flow of floodwater is due in Renmark around the end of December and will be between 190 and 220 gigalitres a day.
This prediction is largely consistent with previous projections.
Current flows across the border are in the order of 180 gigalitres a day.
Should flows reach 200GL a day, the water level at Lock 5 near Renmark is forecast to be around 18.8 metres AHD.
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.
Last week, emergency services personnel began door-knocking homes at risk of inundation and as of last night 5083 premises had been checked. Of those, 1100 properties are still occupied, with 647 indicating an intent to remain on their property once floodwaters arrive.
Of the residents that have advised they intend to leave once flooding occurs, 290 households consisting of 538 adults and 68 children people will require emergency accommodation. A total of 703 properties have so far been inundated.
There are presently 1850 electricity disconnections across at-risk areas, and SA Power Networks are continually assessing the need for further disconnections as water rises.
People are reminded not to go within 50 metres of submerged electricity poles including in canoes, kayaks, surf skis or rowboats.
The SA Housing Authority has established Emergency Relief Centre’s in Berri and Mannum where the public can access information and apply for various forms of support, including financial relief and emergency accommodation.
