Lake Torrens National Park is a protected area located in South Australia about 345 kilometres (214 mi) north of Adelaide.

Environment[edit]

Geology[edit]

Lake Torrens is a 5,700-square-kilometre endorheic saline rift lake in South Australia,and is located in southern Australia. It forms part of the same rift valley that includes Spencer Gulf to the south and is approximately 240 km long. It is in the Lake Torrens National Park, and a permit is required to visit. Lake Torrens is usually a dry salt flat. It has been filled with water only once in the past 150 years – in 1989.

Birds[edit]

The lake has been identified by BirdLife International as an Important Bird Area known as the Lake Torrens Important Bird Area (IBA) because it supported up to 100,000 breeding Banded Stilts during the major filling event of 1989.[2] It may occasionally support over 1% of the world population of Red-capped Plovers. Cinnamon Quail-thrushes are also common in the IBA.[3]

History[edit]

Discovered by Edward John Eyre in 1839, for the following twenty years it was believed that Lake Torrens was an enormous horseshoe-shaped saltpan encircling the northern Flinders Ranges and blocking any path to the interior. The first European to penetrate the mythical barrier was A. C. Gregory from the north in March 1858; later the same year, an expedition under B. H. Babbage and Major Warburton in the north-west also crossed the non-existent barrier near modern Marree. Eyre's horseshoe lake was actually composed of Lake Frome, Lake Callabonna, Lake Blanche, Lake Gregory, Lake Eyre South, and Lake Torrens itself.
