Mapped: Modelling shows what will flood under 120GL, 140GL, 160GL and 200GL daily flows into River Murray

Amid predictions River Murray flows will hit 175GL a day, new maps shows which parts of Riverland towns would flood at 200GL a day – as well as 120, 140 and 160GLs.

More than 4000 properties would be inundated if the River Murray reaches flows of 200GL a day.

Authorities have today increased the peak flow forecast for SA to 175GL a day by the start of December.

New flood maps released by the Department of Environment and Water show areas likely to go under water in a new scenario of 200GL per day.

Previous maps showed flooding at 120GL/day, 140GL/day and 160GL/day.

The maps reveal about 4250 properties would be flooded if the 200GL mark is reached.

This includes hundreds of shacks near Morgan and Mannum.

At 200GL/day, dozens of homes in the town of Renmark would find themselves almost completely surrounded by water.
