The 1956 Murray River flood involved the rising of waters in the Murray River and flooding in three states of Australia, including the towns of Murray Bridge, Mildura, Nangiloc, Red Cliffs, Renmark,[1] Wentworth and many others. Some areas were flooded up to 100 km from the natural flow of the river. The flood was and still is considered the biggest flood in the recorded history of the River Murray and described as "the greatest catastrophe in South Australia's history".[3]
