Soil and land capability, biodiversity and water resource investigations were undertaken in the Nangu Area, located 15 km south west of the community of Wadeye and covering an area of 5,960 ha. Collectively, the results of the investigations provide a comprehensive biophysical assessment of the Nangu landscape.

The information products will support Traditional Aboriginal owners’ understanding of the land capability of the Nangu study area and assist with scoping development opportunities, confident that biophysical risks and opportunities have been identified and understood.

Development potential summary

This summary provides an integrated overview of the land capability, water availability and biodiversity assets of the Nangu study area. The report summarises outcomes from three technical reports and a suite of maps which detail the water resources, biodiversity, and soil, land and vegetation communities of the study area.

Key development potential facts

  • 4,638 ha is predominantly deep, well-drained, sandy surfaced red earths on gentle plains and slopes with good potential for rain-fed or surface water based agricultural development.
  • 2,240 ha classified as having good potential for groundwater based development and a further 2,970 ha identified as having moderate potential.
  • 743 ha contained significant or high value biodiversity values that should be protected from development or soils that are unsuitable for agriculture as they are shallow, very gravelly, subject to flooding, poorly drained or too steep.
  • Local aquifers have a sustainable groundwater yield of approximately 2000 ML per annum with water quality of a standard suitable for human consumption and irrigation purposes. This groundwater yield is sufficient to support approximately 400 ha of irrigated agriculture.

Soil and land

The soil and land capability survey was undertaken in 2017. The report and maps document the soil and land factors likely to impact irrigated agricultural development and highlight the crops most suited to land within the Nangu study area.


The following report and map provide technical details of the Groundwater Resources of the Wadeye Region. The report estimates groundwater quality and bore yield within the study area.


The following report and map document the results of fauna and flora surveys within the Wadeye area, including occurrence and distribution of threatened species, significant habitat and biodiversity risk classes.
