Lake Eyre Basin Surface water Potential Assessment Extents v01

Abstract

This dataset was derived by the Bioregional Assessment Programme. The parent datasets are identified in the Lineage field in this metadata statement. The process undertaken to produce this derived dataset are described in the History field in this metadata statement.

This dataset shows the surface water potential assessment extent (PAE) (version 1) for subregions within the Lake Eyre Basin Bioregional Assessment area. These first pass PAEs include the whole subregion as well as selected surface water features outside the subregion which are deemed to flow out of coal and coal seem gas tenement areas.

These PAEs do not include springs, bores or groundwater features.

Purpose

The role of the PAE is to optimise research agency effort by focussing on those locations where a material causal link may occur between coal resource development and impacts on water dependent assets. The lists of assets collated by the Program are filtered for "proximity" such that only those assets that intersect with the PAE are considered further in the assessment process. Changes to the PAE such as through the identification of a different development pathway or an improved hydrological understanding may require the proximity of assets to be considered again. Should the assessment process identify a material connection between a water dependent asset outside the PAE and coal resource development impacts, the PAE would need to be amended.

Dataset History

The following steps were followed to create each subregion's surface water PAE.

1. Surface water features from Geoscience Australia's 250K stream and lake datasets (GEODATA TOPO 250K Series 3, GUID: a0650f18-518a-4b99-a553-44f82f28bb5f) were opened in ArcMap.

2. Surface water features were selected which flow downstream from existing exploration or production coal and/or coal seam gas tenements (including those tenements under application at the time of creation) (sourced from multiple Queensland and South Australia tenement datasets, see Lineage).

3. Line features were buffered by 1km to create polygons.

4. All surface water polygons were merged with the subregion boundary polygon (Bioregional Assessment areas v02, GUID: e414b1b3-c42e-42e9-9cc4-2093054aa35f)
