Catchments, rivers and creeks



It’s often said that our waterways - rivers, streams and creeks - are like the arteries of the environment. They play an important role in the functioning of the greater system - in this case the catchment. They provide water for habitat, household use, industry, agriculture and recreation. And just like our arteries, need to be cared for to ensure they’re in good working order.

What is a catchment?

As the name suggests, a catchment is an area of land that catches water as it flows through the landscape.  

Catchments can be further broken down into sub-catchments, which are simply the smaller areas of land that drain into a particular area through the smaller watercourse features like creeks, streams and wetlands.  

The plants, trees, rivers, creeks, soils and geology of the area are all part of the catchment, and so are the man made elements of the land – the houses, roads, factories, farms, and businesses that make up the landscape.  

All of these elements are connected by our waterways. For this reason, everything that occurs within a catchment can affect the health of the waterways and surrounding environment.

Campbelltown's catchments

Most of Campbelltown’s local government area (or LGA) drains into the Georges River catchment, while a smaller area drains into the Nepean River catchment.

The Georges River catchment covers an area of almost 1000 square kilometres, and supports a range of land uses, including market gardens, agriculture, mining, industrial manufacturing, landfill and army firing range.

While the catchment is highly urbanised in some areas, large areas of the bushland surrounding the river - including remnant floodplain forests of the Cumberland Plain - are some of the most pristine in western Sydney. A large corridor from Appin to Glenfield has been protected as part of the Georges River Regional Open Space Corridor.

Georges River Combined Councils Committee

Formed in 1979, the Georges River Combine Council Committee’s (GRCCC) mission is to advocate for the protection, conservation and enhancement of the health of the Georges River, by developing programs and partnerships and by lobbying government organisations and other stakeholders.

The GRCCC represents local councils in the Georges River Catchment of NSW. Members include nine local councils: Campbelltown City, Rockdale City, Sutherland Shire, Kogarah City, Hurstville City, Bankstown City, Liverpool City, Fairfield City and Wollondilly Shire councils. It is an incorporated association of local councils working in partnership with State and Federal Government agencies and community representatives within the Georges River Catchment.

Programs delivered under the auspice of the GRCCC include:
