The name for the system of barriers is derived from the town of Goolwa , which is located at the mouth of the Murray River. The barriers connect the Sir Richard Peninsula near Goolwa in the west via various islands with Pelican Point on the Narrung Peninsula in the east. The road that leads over the barrages and the islands is over 26 kilometers long.
