What is the Coorong?

The Coorong is a saline lagoon located in South Australia.


How was The Coorong formed according to Ngarrindjeri oral tradition?

The formation of the Coorong is intricately linked to their Dreamtime stories. One such story involves the actions of ancestral beings and natural forces shaping the landscape over time. While specific details may vary among different storytellers, the general narrative often revolves around the actions of powerful Dreamtime beings like Ngurunderi, the Rainbow Serpent, and other ancestral figures.

In Ngarrindjeri lore, Ngurunderi is a significant figure credited with shaping the landscape of the Coorong and surrounding areas. According to some versions of the story, Ngurunderi traveled through the region, pursuing a giant Murray cod named Pondi. During his journey, Ngurunderi created the waterways, rivers, and lagoons that now define the Coorong, shaping the land with his actions and leaving behind a landscape that provided sustenance and resources for future generations.

Additionally, the Rainbow Serpent, Wai-nang-kotchi, is often associated with the creation of waterways and landforms in Aboriginal Dreaming stories. It’s believed that Wai-nang-kotchi’s movements and actions carved out rivers and watercourses as she traveled across the land, leaving behind a network of interconnected waterways, including those found within the Coorong.

These Dreamtime stories offer a cultural and spiritual explanation for the formation of the Coorong according to Ngarrindjeri tradition. They highlight the deep connection between the Aboriginal peoples and the land, as well as the significance of ancestral beings and natural forces in shaping the landscape and providing a foundation for life in the region.

 

How was the Coorong formed?

The Coorong unveils its geological tale as a labyrinth of intricate and ancient sand dunes. The most ancient among them, dating back approximately 120,000 years, lay the foundation for this natural wonder. Another dune formation, aged around 80,000 years, still graces the landscape of Younghusband Peninsula. The contemporary Coorong, however, emerged between 6,000 and 20,000 years ago, when rising sea levels transformed the 80,000-year-old dune into an island, giving rise to a lagoon nestled behind the current line of coastal dunes. Initially, the lagoon likely boasted numerous sea access points, but the relentless dance of wind and sand over millennia gradually sealed them off, sculpting this distinctive isthmus of land.

 

Is the Coorong freshwater or salty water?

The Coorong is salty or Hyper-Saline not fresh. Divided into the North Lagoon and the South Lagoon by the narrows at Parnka Point. The two lagoons are distinct from the Murray Estuary leading from the mouth to Goolwa Barrage. The aquatic environment ranges from estuarine in the North Lagoon to hyper-saline in the far reaches of the South Lagoon.

How many Barrages are there alone the Coorong?

There are 5 barrages: Goolwa Barrage, Mundoo Barrage, Boundary Creek Barrage, Ewe Island and Tauwitchere Barrages. Goolwa Barrage, located 8km upstream of the Murray Mouth, is the deepest of the barrages and is constructed on fine sand and silt. It is founded on timber piles and sheet piling up to 14m deep. Ewe Island and Tauwitchere Barrages are wide and shallow barrages built on a calcareous reef, with earth embankments at both ends. The Mundoo Barrage and Boundary Creek Barrage are the shortest of the barrages and are founded on a limestone reef.

 

The Coorong, Lower Lakes and Murray Mouth are a system of lakes?

Lagoons and wetlands which form the terminus of the River Murray. The diverse environmental, economic, social and cultural values offered by the Coorong and Lower Lakes has been formally recognised by the declaration of portions of the system as a wetland of international importance under the Ramsar convention and the area’s nomination as an Icon Site under the Living Murray Initiative. The system covers approximately 140 500 hectares (ha) and contains both fresh water and estuarine ecosystems. There are three major bodies of water – Lake Alexandrina, Lake Albert and the Coorong.


Lake Alexandrina

Lake Alexandrina is the largest of the lakes with an area of 76 000ha. The lake is relatively shallow, with a maximum depth of approximately 4 metres (m), and is fed by fresh water from the Murray River and rivers from the Mt Lofty ranges. The Murray passes through Lake Alexandrina to the sea. The lake receives the majority of its fresh water from the Murray, although local rainfall and runoff from the Mt Lofty Ranges also contributes substantial inflows. Historically, the lake has been a predominantly fresh to brackish water system which, in the pre-European period would have occasionally become saline for short periods during extreme droughts. Currently the water in the lake is highly saline near the barrages and brackish in the centre.

Lake Albert

Lake Albert is a smaller fresh water lake connected to Lake Alexandrina. It has an area of 16 800ha and is shallower than Lake Alexandrina. It has no other significant inflows and is not connected to the sea.


What is Coorong Mullet?

Yellow eye mullet (Aldrichetta forsteri).

The mullet when living in the Coorong takes on a distinctive sweet flavour. The flavour of the flesh varies slightly according salinity of the Coorong and food sources. The flesh is moist with a soft to medium texture. As the fish fillets are small they cook quickly. Best when fresh or frozen fresh, the sweet flavour strengthens over time, as the high oil content oxidises.

Is the Coorong Tidal?

The Coorong’s vitality hinges on a delicate interplay of river currents, tidal rhythms, runoff from surrounding landscapes, and groundwater from the Upper South East Drainage scheme area, all choreographed by the whims of the wind. However, the past decade has borne witness to diminished river flows, a shrinking tidal prism, and the gradual silting of its mouth, culminating in the South Lagoon’s hypersalinity surpassing its natural thresholds.

 

How long is the Coorong?

The Coorong is a long, shallow saline lagoon that stretches more than 100 km and that is separated from the Southern Ocean by a narrow sand dune peninsula. It marks the termination of Australia’s longest river, the Murray
