Catchment management

A catchment is an area of land bounded by natural features such as hills, where stormwater flows to a common low point such as a creek, lake or river. Parramatta and its suburbs cover an area of 84km2 at the foot of the Hills district, 24km from Sydney. These hills, and the valley below, make up part of the catchment of the Parramatta River.

As a member of the Parramatta River Catchment Group (PRCG), we're focused on working together to improve the health of the Parramatta River catchment.

Members of the PRCG include staff and councillor representatives from Cumberland, Inner West, Blacktown, Canada Bay, Ryde, Hunters Hill, Canterbury Bankstown, and Parramatta Councils, as well as Sydney Water and other state government agencies and authorities. Members meet regularly to address various issues such as stormwater pollution, estuary health and the protection of biodiversity corridors through information sharing and collaborative initiatives. 

The creeks of the Upper Parramatta Catchment (including Coopers, Darling Mills Creek, Hunts Creek, Quarry Branch, Finlaysons, Greystanes, Pendle Hill and Toongabbie Creeks), Duck River Catchment and the Lower Parramatta River Catchment (including Vineyard, Subiaco, Clay Cliff, and Brickfield Creeks) all eventually flow into Parramatta River.

The only catchment area in Parramatta that doesn’t flow into Parramatta River is the Lane Cove Catchment, which comprises Terrys Creek and Devlins Creek. These creeks make their way to Lane Cove River.
