More developments for the Sound in the pipeline
Since the late 1960s, Cockburn Sound’s unique environment has come under a wide range of pressures as the result of increasing industrialisation. Just some of the environmental stressors the Sound endures include concentrated brine outflow from the desalination plant, ongoing dredging for cement production, contaminated land and groundwater input, nutrient discharges flow restriction caused by the Causeway and coastal modification.
The Cockburn Sound environment
Cockburn Sound is a sheltered marine embayment south of the Swan River mouth at Fremantle. It is 22km long and ranges from 15km wide in the north to 9km in the south with an area of about 124 square-kilometres. Its central basin is between 17-22m deep, flanked by the relatively steep slopes of the surrounding banks. Garden Island extends along the western side of the Sound providing protection from prevailing winds and ocean swells.
