The Northern connectivity event
In 2018, Commonwealth and NSW environmental water holders released water from storages in the Northern Murray-Darling Basin to support the environmental health of river systems including the Barwon-Darling down to Wilcannia and beyond for local communities and the fish and ecosystems that depend on them.
The Northern Connectivity Event Final Report
As a result of the Barwon-Darling ceasing to flow for an extended period, native fish and other aquatic life were under considerable stress in early 2018. The Northern Connectivity Event (NCE) ran between April and July 2018 improving water quality right along the river system. Water for the environment was released from Glenlyon and Copeton dams near the Queensland / NSW border. Connectivity between waterholes was achieved to the Menindee Lakes, near Broken Hill. In total, over 2,000 km of the Gwydir, Mehi, Dumaresq, Macintyre and Barwon-Darling rivers benefited from the flow. Water for the environment was contributed by both the Commonwealth and New South Wales (NSW).
There was strong community interest in the NCE. Towns along the river looked forward to the arrival of the flow. The NCE also provided the opportunity for government agencies to work together.
Whilst flow events such as the NCE are not expected or possible in many years, the NCE provides an example of what is possible under the Murray-Darling Basin Plan. Outcomes from the event are outlined in the Northern Connectivity Event Final Report.
