Water quality is generally good throughout the Basin but can be compromised by a number of threats, including high salinity, blue-green algal blooms, low dissolved oxygen levels, nutrients, bushfires and turbidity. Natural events such as droughts, floods and high temperatures can also quickly degrade water quality.
Keeping this in consideration, what problems is the Murray Darling Basin facing?
Many issues affect the water resources and ecosystems of the MDB including salinity, erosion, blue-green algal blooms, water quality, and invasive species. Climate change and resultant possible increases in drought pose a significant risk to the availability of surface water in the MDB.
