Monitoring water quality in our rivers and creeks

Wednesday 10 January, 2024
Following the recent high rainfall, we're keeping watch on water quality in our waterways.

One of the ways we're doing this is by monitoring dissolved oxygen levels.

Dissolved oxygen is a measure of how much oxygen is dissolved in the water - the amount of oxygen available for aquatic organisms such as fish.

High rainfall and floodwaters carry large amounts of organic material like leaves, twigs and grass into our rivers and creeks which turns the water a dark brown or black colour.

As bacteria eat the organic material, they also consume the oxygen dissolved in the water, reducing the amount available for fish and other water animals.

The diagram shows a scale of dissolved oxygen levels with 0 (purple) being the worst for fish and 9 (green) being the best.

Information on water quality and dissolved oxygen levels in some waterways is available on our website: Water Quality and Dissolved Oxygen - GB CMA - Goulburn Broken CMA

 

 

The Goulburn Broken CMA acknowledges and respects First Nations people and the deep connection they have with their land and waters.


We acknowledge the Yorta Yorta and Taungurung people and their ancestors/forbears as Traditional Owners of the land and waters in the Goulburn Broken Catchment (and beyond). We value our ongoing partnerships with Yorta Yorta Nation Aboriginal Corporation and Taungurung Land and Waters Council for the health of Country and its people.


We pay our respects to Elders past, present and emerging and acknowledge and recognise the primacy of Traditional Owners obligations, rights and responsibilities to use and care for their traditional lands and waters.
