MDBA
The likelihood of water quality issues increases under warmer conditions.
Key water quality issues:
- Harmful algal blooms: Algae can pose a risk to the health of humans, animals and the environment.
Blue-green algae levels remain elevated across much of the Basin including in NSW’s central-north, Menindee/lower Darling, NSW/VIC mid-Murray regions, and in VIC’s central-north.
- Bushfire contamination: Rainfall-mobilised ash, debris, and topsoil following fire can pollute waterways and jeopardise the health of aquatic biota.
Post-fire contamination of waterways in the upper Murray & Mitta regions remains a threat following recent regional bushfires and rainfall.
Water quality within the Basin is monitored by individual States. Any site-specific alerts, warnings or advisories are issued by those respective States.
