Black Water in the Murray River

Last updated: 2pm, 18 November 2016

Speed, Patchewollock, Tempy, Nandaly, Lalbert, Lalbert, Ultima, Nullawil, Culgoa, Berriwillock, Chinkapook, Chilllingollah, Waitchie and Murray River supplied rural piplines

Black water alert

Reason: Black water in the Murray River


As a result of flooding in September and October 2016 large amounts of organic matter, such as leaves and wood, have been moved from swamps, forest and wetlands situated along waterways. Return flows from these areas are bringing dissolving organic matter into the Murray River, changing the water to a dark tea colour ('black water').

Water Quality in the Murray is improving and indications are that it may pass in a few weeks. Water quality laboratory results taken from our river pump stations indicate that the worst of the black water has moved past most of our pump stations.

We are continuing to monitor and improve water quality where possible and we remind customers that they can continue to use their water for non-drinking purposes.

More information on each area is detailed below.

If you have any concerns, please contact our difficulties and faults number on 1800 188 586 at any time.
