Catchment Management
A catchment is an area of land, bound by hills or mountains from which all runoff water flows to the same low point. The low point could be a lake, dam, a river or the mouth of a river where it enters the ocean. Rainwater will flow to this lowest point, via creeks, rivers and stormwater systems.
Auburn local government area predominately falls within the Parramatta River Catchment. The catchment also includes the local government areas of Ashfield Council, Bankstown City Council, Blacktown City Council, Burwood Council, City of Canada Bay Council, Holroyd City Council, Hunters Hill Council, Leichhardt Municipal Council, Parramatta City Council, City of Ryde Council, Strathfield Municipal Council and The Hills Shire Council.
The Parramatta River is the main tributary of Sydney Harbour; the River extends from Blacktown in the west to Lane Cove in the east. Auburn City Council is a member of The Parramatta River Catchment Group (PRCG); The PRCG is a regional organisation of local councils, state agencies and community representatives whose aim is to work together to improve the health of the Parramatta River catchment.
Haslams Creek
Haslams Creek begins in Rookwood; it flows via a formalised channel system from the M4 motorway to the Hill Road Bridge from this point it forms a natural channel which flows through Sydney Olympic Park and joins Parramatta River at Homebush Bay. Haslams Creek catchment is 17 square kilometres, it is highly urbanised with a large percentage of industry operating throughout the area.
Duck River
Duck River is 11.5 kilometres in length, it begins in Birrong in Bankstown City Council area; it flows in a north easterly direction through a formalised channel system until it reaches the Sydney Water pipeline at Sefton. The River enters Auburn Council local government area at this point and becomes a more natural watercourse, it continues through to Silverwater where it enters the Parramatta River. Duck River forms the local government area boundary of Auburn and Parramatta council’s.
Duck River is a freshwater system from Birrong to Clyde weir, the zone from the Sydney Water pipeline to Clyde weir is referred to as Upper Duck River. The tidal zone of the River runs from Silverwater to the base of Clyde weir, this is referred to as lower Duck River.
The Duck River corridor contains regionally significant areas of natural bushland and wildlife habitat occurring within an otherwise highly urbanised landscape. The open space corridor associated with the Duck River also incorporates numerous recreational facilities of regional significance. As well, the area provides opportunities for passive recreation and there is habitat for a number of native flora and fauna species and sensitive vegetation communities.
