[1][2] An ephemeral stream originating from the remnant vegetation Beni forest to the east flowing approximately 10 kilometres via Troy Gully north-west through grazing land, heavy residential, industrial and terminating into the Macquarie River system.
Troy Creek has suffered significant scalding and vegetation loss as a direct result of salinity.
Sections within the catchment have recorded soil salt levels twice that of sea water and over ten times tolerable to native grass and tree species.
Local land care volunteers, businesses, and school students have planted thousands of trees in Troy Gully (upstream of Yarrandale Rd.)
