Maps and spatial data

We use maps and spatial data, including remote sensing data daily, to support our various programs and projects. This includes data on hydrology, biota, terrain, vegetation, geology, and important built and natural assets.

Murray–Darling Basin boundary

This simple small-scale map shows the approximate border of the Murray–Darling Basin as defined in the Murray–Darling Basin Agreement of the Water Act 2007, and in relation to state boundaries, rivers, coastline and select cities and towns.

Water resource plan areas (WRPA) for surface water

The boundaries of the 20 surface-water water resource plan areas as defined by the Basin Plan. Surface water only is represented here (water in a watercourse, lake or wetland, or flowing over or lying on the land's surface).

Water resource plan areas (WRPA) for groundwater

The boundaries of the 22 groundwater water resource plan areas as defined by the Basin Plan

Traditional Owners for water resource plan areas

Traditional Owners for the 22 groundwater water resource plan areas and 20 surface-water water resource plan areas as defined by the Basin Plan

Surface water SDL resource units

The boundaries of the 29 surface water Sustainable Diversion Limit (SDL) resource units as defined by the Basin Plan. The surface-water SDL is the maximum long-term annual average quantity of water that can be taken on a sustainable basis from water resources in a surface-water SDL resource unit.

Groundwater SDL resource units

The boundaries of the 66 groundwater Sustainable Diversion Limit (SDL) resource units as defined by the Basin Plan. This includes 7 groundwater SDL resource units for deep groundwater. A groundwater sustainable diversion limit (SDL) resource unit describes a geographical area which encompasses a set of water resources.

Water Quality zones

The boundaries of the Water Quality Regions/Zones as defined by the Basin Plan. This dataset is subdivided into altitude zones — these correspond to 1 of 7 categories: Montane, Upland, Slopes, Lowland, Upper, Middle, Lower and Mt Lofty.
