Oyster Harbour catchment

Oyster Harbour is adjacent to the town of Albany on the South Coast of Western Australia. Two major rivers (the Kalgan and King) are connected to the northern harbour, and are estuarine (that is, influenced by tidal marine exchange) for  approximately nine and seven kilometres, respectively. Yakamia Creek meanders through urban areas of Albany and enters the harbour on the south-western side.

The catchment of Oyster Harbour is approximately 3,000 km² and extends north to the Porongurup and Stirling ranges. Approximately 70 per cent of the catchment has been cleared.
