Travelling Australia - Journal 2006
16-21 March 2006 - Port Elliot  (Coorong)

One day we went on a tourist boat trip from Goolwa along the Coorong (the narrow body of water running for tens of kilometres behind the ocean dunes and established as a national park about 20(?) years ago. The boat passes through a lock in the Goolwa Barrage (one of several barriers stopping salty ocean water getting into Lake Alexandrina and marks a definite boundary between fresh water and salt water in the water system around the mouth of the Murray). Then we went for about an hour along the Coorong looking at the scenery. The high point was undoubtedly the waterbird life; there seemed to be waterbirds in large numbers all over the place. Pelicans are most obvious because of their size and numbers but many other species were easily seen from the boat.
Goolwa Lock Lock in the Goolwa Barrage allows vessels to pass through the barrage.
Fish ladder in the barrage Fish ladders allow migratory fish to pass through the barrage. Some fish species must migrate between salt and fresh water to complete their reproductive cycle.
Cruise boat Cruise boat run onto the sand while the passengers explore ashore.
Ocean beach Ocean beach on Encounter Bay near the entrance to the Coorong and Murray River. Pipi bivalves are harvested from this beach.
Glasswort plant Glasswort is commonly found in salty habitats, this is growing between the Coorong and the ocean beach. Parts of this plant are edible.
Dune Dune in the background on the Younghusband Peninsula separate the ocean beach from the Coorong. The birds are standing on a mud bank.
Mouth of Murray The mouth of the Murray marked by breaking waves in the distance. Wave action and water running out of the river erode the sand allowing the mouth to move along the coast apparently at random.
Dredge Dredge working inside the entrance to the river draws sand up from the river bed then pumps it to a dump point on the ocean beach.
