 The Canning River rises not far from North Bannister, southeast of Perth and joins the Swan at Applecross, opening into Melville Water.The river then narrows into Blackwall Reach, a narrow and deep stretch leading the river through Fremantle Harbour to the sea.The Noongar people believe that the Darling Scarp represents the body of a Wagyl (also spelt Waugal) – a snakelike being from Dreamtime that meandered over the land creating rivers, waterways and lakes.
