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.

How high the River Murray is likely to get in Morgan

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.
