The Goolwa Barrages comprise five tidal barrages in the channels separating Lake Alexandrina from the sea at the mouth of the River Murray, near Goolwa, in the Coorong National Park, in South Australia. They were constructed principally to reduce salinity levels in the lower reaches of the River Murray, Lake Alexandrina and Lake Albert, but also to stabilise the river level, for both upstream irrigation and pumping.
