Water quality describes and measures the suitability of a particular body of water for a specific use, but it can also indicate the relative health of a waterway too.

Georges River mangroves

Mosquitoes can form large swarms at certain times of the year in the suburbs around the Georges River. They are as much a component of natural ecosystems as any other native wildlife, but when there are lots of them they are a nuisance for people.


The Georges River flows through a very varied landscape from the almost fully-urbanised lower coastal reaches through to the steep-sided, heavily-wooded upper reaches near Appin.

Introduced animals

The Georges River catchment is unfortunately threatened by many introduced animals. Cats and foxes are a big threat to native animals, preying on birds, small mammals and reptiles.


Weeds have a significant impact on our catchments and are a threat to native flora and fauna as well as the health of our waterways.
