Lake Eyre Basin - River Basin, 1997

Abstract

The dataset was derived by the Bioregional Assessment Programme from 1997 Australia's River Basins dataset (GUID: d4561e86-2d13-4dcb-bf9e-aae75ba4850c). The Lake Eyre Basin, River Basin was extracted and was used to derive the Lake Eyre Basin Bioregional Assessment Boundary. The source dataset is identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.

The following abstract is taken directly from the source dataset:

Australia's River Basins 1997 is the result of a joint State and Commonwealth project to create a national spatial database of major hydrologic basins. The data has been derived from topographic maps at scales ranging from 1:10 000 to 1:250 000. These basins are the primary building block for the collection of national hydrologic data and the assessment of water resources.

Australia is divided into drainage divisions. The drainage divisions are sub-divided into water regions, which are in-turn sub-divided into river basins. Statistics are gathered and used at all three levels.

This database contains boundary information for 12 divisions, 77 regions and 245 basins. It also contains, for each basin, information relating to its individual basin/region/division name and number. State borders are also included in the data. Data for Division XIII Distant Islands Division is not included.

The former Australian Water Resources Council (AWRC) formally defined the drainage divisions and river basins in the early 1960s and, with minor modifications resulting from improved mapping of the inland arid zone area, has been the basis for the study of Australian hydrology since. The drainage divisions were defined by both the major topographic features of the continent and the main climatic zones to give broadly homogenous hydrologic regions. Within the drainage divisions, the river basins are defined by the major watershed lines.

Purpose

This dataset provides a standalone polygon shapefile of the Lake Eyre Basin - River Basin for use in the Lake Eyre Basin Bioregional Assessment area.

Dataset History

All features from the Australia's River Basins 1997 dataset (GUID: d4561e86-2d13-4dcb-bf9e-aae75ba4850c) with the 'DNAME' attribute field populated as "LAKE EYRE" were merged and exported into this dataset. No attributes were retained.

Source lineage:

Data for basin boundaries have been captured by relevant State and Territory authorities from 1:10 000 and 1:250 000 scale source material.
