The water-dependent asset register for the Pedirka subregion is a simple and authoritative list of assets within the preliminary assessment extent that are potentially affected by changes in water due to coal seam gas and coal mining development.
This register was extracted from the subregion's asset database in August 2015.
Preliminary assessment extent
The development of the preliminary assessment extent for the Pedirka subregion was carried out by South Australian Department of Environment, Water and Natural Resources.
The preliminary assessment extent was based on the geological Pedirka Basin boundary, the Great Artesian Basin boundary, and the known coal beds and existing exploration licences in the area.
The coal beds lie between Andado Station in the Northern Territory and Dalhousie Springs in South Australia. The preliminary assessment extent extends up to 210 kilometres in most directions from the locations of the coal beds, extending north–south from the eastern MacDonnell Ranges to William Creek, and east–west from near Birdsville to Cooper Pedy. It encompasses almost all of the Simpson Desert, and the river catchments that drain into the north-western corner of Kati Thanda–Lake Eyre, including the lower reaches of the Finke River, Macumba River and Neales River. It includes Dalhousie Springs and the northern part of the Lake Eyre supergroup of Great Artesian Basin springs.
There were 1052 water-dependent assets identified in the preliminary assessment extent for the Pedirka subregion and included in the water-dependent asset register.
Ecological water-dependent assets
There are 992 ecological water-dependent assets in the Pedirka subregion. They include:
- the habitats of 11 threatened or endangered species
- six nationally important wetlands
- three nationally important bird habitats
- one nationally-listed threatened ecosystem
- 68 lakes and wetlands.
Economic water-dependent assets
There are seven economic water-dependent assets. They include rivers and creeks.
Sociocultural water-dependent assets
The 53 sociocultural water-dependent assets include:
- six heritage-listed sites
- 36 Indigenous sites
- 11 recreation sites.
Many of the sociocultural assets were also classified as ecological assets.
