AN imminent peak in the River Murray will threaten South Australian towns with 1992-93 flood levels, and more is on the way.
But the Department for Water’s Murray Darling Basin operations manager Andrew Beal said river levels were likely to drop before water from the Queensland and Victorian floods arrived.
Recent updates from the department predicted peak flows of between 65,000-75,000 megalitres per day across the State border in late January to mid-February but a flow advice update issued on Friday has upgraded the flow to 90,000ML a day.
The 1992-93 flood peak saw about 93,000ML per day enter the State and, while little damage was caused in the Murraylands, several shacks and low-lying areas were inundated.
Mr Beal said the State was looking at a repeat of 1992-93 but current conditions were not likely to push flows much over 90,000ML/day.
“(The Queensland and Victorian floods) will extend the period of high flow but not the peak flow,” he said.
He said shackowners should prepare for inundation in coming weeks if their properties were affected by floods such as those in the early 1990s, but more major rain would be needed in the southern basin before a major flood risk emerged in the Lower Murray.
