Preliminary Assessment Extent (PAE) Pedirka subregion v03

## **Abstract** 

This dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.



This dataset was created for the Bioregional Assessment by the Government of South Australia, Department of Environment, Water and Natural Resources. The data presents the approach taken to develop a Preliminary Assessment Extent (PAE) for the Pedirka Basin. This mapping and geospatial data, represent draft information presented to the Bioregional Assessment Team, which will be amended as required to support the Bioregional Assessment Programme. It is understood that the Pedirka PAE will be subject to revisions as new ecological, hydrological and hydrogeological information and understandings become available.

## **Dataset History** 

This dataset was created for the Bioregional Assessment by the Government of South Australia, Department of Environment, Water and Natural Resources. See the attached document relating to the methodology and assumptions in PAE development for more information



The following methodology was followed to formulate the Arckaringa PAE:

&#xB7; Inferred 210km groundwater drawdown extent assumes potential for up to 50 year LOM and large scale mining operations from DEWNR modelling undertaken in the Pedirka subregion for the Eromanga Basin based upon around 400ML/day over 50 years to 1m drawdown.

&#xB7; Westerly and southern boundaries follow the Great Artesian Basin (GAB) and Arckaringa Basin boundaries taking the further boundary from coal beds to identify potential groundwater connectivity.

&#xB7; Pedirka basin boundary (DEWNR Dataset).

&#xB7; 10 km buffer included where PAE intersects with fractured rock aquifer (FRA) extents.

&#xB7; DMITRE Mapped areas of economic coal beds (Coal beds).

&#xB7; Phreatic surface information was utilised to identify connectivity to shallow groundwater potentially utilised by vegetation, which was identified up to a 10m depth, based upon decisions made by the Bioregional Assessment team for other PAEs.

&#xB7; Tertiary sediments were excluded from consideration as a buffer to the GAB where they intersect with coal deposits as it was assumed direct impact to the tertiary sediments would occur should open cut mining activities occur.

&#xB7; Exploration Licences (EL) as lodged with DMITRE.

&#xB7; Known watercourses (surface water data) (DEWNR dataset).

&#xB7; Surface water basins - all of Macumba catchment surface waterbodies included (i.e. including sub catchments outside the Pedirka boundary) and downstream to the confluence with the Kallakoopah

&#xB7; Upstream catchments of the Neales-Peake outside of the inferred 210km drawdown zone have been included on the basis that some of the springs support critical refuges for aquatic species that inhabit upstream reaches.

&#xB7; 20km buffer boundary included as a contingency around known surface waters and groundwater drawdown extents, however all watercourse buffers are within the groundwater drawdown extent.

&#xB7; Springs locations with SA (DEWNR dataset) + national springs database compiled for the Recovery Plan by Fensham et al. 2005).

&#xB7; GAB springs of the Lake Eyre supergroup included with a 5km buffer around the point location to accommodate the extensive wetland and terrestrial ecosystems the spring support. It is noted that the impacts of drawdown on pressures would reduce further from the coal resource but recognising that there may be ecological dependencies between the springs.

&#xB7; A potentiometric surface has been generated for the GAB aquifer (Cadna-owie Formation - Algebuckina Sandstone and equivalents) for the SA and NT portions of the GAB.

&#xB7; Lower reaches of the Finke are within the 210km buffer around the Pedirka coal beds, which includes the Snake Gully/ Finke river floodout.

&#xB7; Dalhousie springs complex is within the 210km drawdown extent.

&#xB7; Water assets have been identified within northern areas of the Pedirka PAE based upon conservative assumptions that unknown vegetation dependency occurs from groundwater and shallow groundwater. This includes the Hale, Hay and Plenty Rivers together with wetlands of significance (Allitra tableland wetlands and Lower Plenty Lakes).

&#xB7; Water assets have been identified within northern and eastern areas of the Pedirka PAE based on unknown terrestrial vegetation dependency on groundwater and shallow groundwater. Water assets include poorly studied floodout forest (dense riparian vegetation) of the Hale, Hay and Plenty Rivers together with wetlands of significance (Allitra tableland wetlands, Lower Plenty Lakes and Mulligan River salt lakes). It is however recognised that no GAB springs exist within the eastern areas of the Pedirka PAE.
