When early European explorers looked for the Murray Mouth they had high hopes of finding a natural harbour suitable for shipping. Had they found such a harbour, the Murray would have been used far more as a means of connecting many parts of inland Australia with the coast and beyond. Instead, what Captain Charles Sturt found was a treacherous river mouth that punched a channel through sand dunes into the sea. Captain Charles Sturt (April 28, 1795 _ June 16, 1869), Australian explorer, was born in India and joined the British Army as a young man, seeing action with the Duke of Wellington in Spain and at Waterloo. ...

The Murray Mouth's location is changeable. Historical records show that the channel out to sea moves along the sand dunes over time. At times of greater river flow and rough seas, the two bodies of water would erode the sand dunes to create a new channel leaving the old one to silt and disappear. The mouth is between two sandhill peninsulas. Sir Richard Peninsula on the northwest separates the Goolwa channel (the main river channel) from the ocean. The much longer Younghusband Peninsula separates the Coorong from the ocean on the southeast of the mouth. The Murray Mouth is separated from Lake Alexandrina by a row of low islands. The largest one, directly facing the mouth, is Hindmarsh Island. A series of barrages join the islands, separating the salt water from the fresh water of the lakes and river. The barrages can be opened during high river flow. Goolwa (35°30′ S 138°46′ E, population approx 2400) is a river port near the mouth of the River Murray in South Australia. ...

What made the Murray Mouth so dangerous to shipping in the past was the unpredictability of the currents and the depth of the channel. At high tides, sea water flows in through the channel and into the Coorong National Park's lagoon system. At the Mouth, the Murray flows eastward until it turns south for the last few hundred metres. To the east of the mouth river water and high tide sea water can continue eastward for over a 100km into magnificent saltwater lagoons protected from the fierce ocean by tall sand dunes.

River Murray water is used by farmers for irrigation in 4 of Australia's states, as well as supplying water to most towns along the river, and many further away through various pipelines. It has been widely accepted that too much water is being extracted, however business and political concerns make it difficult to remedy the problem. A visible symptom of the over extraction of river water is the closing of the Murray Mouth. Since the early 2000s, dredging machines have operated at the Murray Mouth, moving sand from the channel to maintain a minimal flow from the sea and into the Coorong's lagoon system. Without the 24 hour dredging, the Mouth would silt up and close, cutting the supply of fresh sea-water into the Coorong, which would then warm up, stagnate and die.
