Water is being released down the Darling-Anabranch in Far West New South Wales today for the first time since 2017.
The anabranch leaves the main Darling River just south of the Menindee Lakes and runs down to the Murray River, just west of Wentworth near the border with Victoria.
The Interim Commonwealth Environmental Water Holder, Hilton Taylor, said they were anticipating about 100 gigalitres would be needed to send water all the way through the system.
He said releases would come out from Lake Cawndilla in Menindee.
"Flowing all the way through to the Murray to connect these fish and this old paleo stream, as it's called," he said.
Balancing water use and preservation
Mr Taylor said water authorities were comfortable about releasing the water now.
He said quite a bit of water was still coming down the basin system, the Menindee Lakes were already surcharged above their full supply limit and the long term forecast was for good spring and early summer rain.
"This is part of the communication and conversations with the local community and the water resource managers."
Summer oasis
Wyndam Station's Angus Whyte, who lives along the anabranch, said the release was "absolutely ideal".
He said the river would be beautiful this summer.
"I reckon the yabbies will appreciate it, certainly the wildlife, the birds," he said.
"So really really happy about that."
