Hut owners along the Murray River in South Australia are receiving local advice to prepare for possible flooding.
Key points:
- Some barracks owners have begun relocating their belongings to prepare for a flood
- There is more water in the system due to the weather conditions in La Niña and the dams upstream.
- Shacks are at risk of water damage when the flow reaches 60 gigaliters per day
Mark Dutton owns the second lowest hut in Morgan City, about two hours east of Adelaide.
His house has been flooded twice before and he knows it could sink again soon.
“You just have to be more discriminating with the help you render toward other people.
“It’s part of the beauty of the area after a flood, it’s amazing, the life of the birds in the backwaters comes to life.

“We saw spoons from our back balcony fishing for jabbies in the conservation park behind our site.
“But obviously to get a lot of furniture moving, you have to clean up a lot after a flood. And you have those long periods of time when you can’t access your shack, let alone use it.
“Indeed, your place becomes the bottom of the river, so you have to clean up all that mud, mud and mud from there. So it’s a bit of a threat. It’s a little nasty.”
Mr Dutton says the water reached about three feet inside his shack, causing $ 15,000 to $ 20,000 in damage. (Provided by Mark Dutton)
Dutton said that while he understood the risk to his property, he wanted prior notice from authorities.
“On both occasions in the past, flood warnings come from the ferry operator,” he said.
“When the water comes … it is an unstoppable force, and it stays there for a while.
“So, bottom line is that we’re really looking forward to it.

Mid Murray Council CEO Ben Scales said preparations to protect the infrastructure and alert property owners were underway.
“Our plan will be to look at our assets, our swimming systems and the potential roads we have, which we know create problems depending on the flow of the river and some pontoons on the ramps of our boats, where we have to try to take away “If it goes up too much,” he said.
“More health at Murray”
Downstream in Mannum, David Hartley and his wife Wendy run a business that rents river huts for vacation.
He said the increase in flows had been an attraction for visitors, with a lot of wildlife around.
“The Pelicans [have] all have disappeared because they are in areas that have already been flooded, “Hartley said.
“There seems to be a lot more cormorants, more egrets and just your general cormorants, but there seems to be a little more health in the Murray.”
Hartley said he would keep the books open for the 90 properties, but would offer refunds if any shack were cut down by the floodwaters.
“With that happening in the winter as well, it’s not really the traditional time of the river, so a lot of people are very happy to still go up and look at the high water and something a little different,” he said.

Where does the water come from?
Continued wet weather has meant that unregulated flow (river water that is not yet in use) has been flowing in South Australia since July last year.
The water flowing along the border reached a maximum in December at about 37 gigaliters a day in winter and has dropped to about 28 gigalitres a day, but the rains sustained during the autumn and now winter have made the unregulated flow continues for some time.
Chrissie Bloss, water supply manager for the Department of the Environment and Water (DEW) says about 40 gigaliters a day is needed to provide benefits to the floodplains.
“We had a very good barrage discharge which has helped to cool the Coorong, it has been very good from the environment of the lower lakes,” he said.
DEW plans to irrigate the floodplain and raise dams in late winter and spring, with regulators set to activate in Chowilla, Pike and Katarapko.
Inlets in southern Australia are expected to increase in the coming weeks with rain falling on the catchments of the Murray River and more Darling water being introduced into the system.
“At 40 gigaliters per day [DEW] it will issue high-flow advice just to let people know that the river is moving faster and water levels will rise, ”Ms Bloss said.
“If the forecast reaches 60 gigaliters per day, that is when a minor flood warning will be issued for the shack areas between Morgan and Mannum, but at the moment there are no indications that the river will reach that high.”
