Introduction

There is no major infrastructure or diversion for surface water extraction within this SWMA. This management area is same as the NT portion of Warburton Basin, and is Aboriginal land. The management area is surrounded by Petermann Range in the north and many mountain ranges in the south on the border with South Australia. During the Wet few creeks flow from the ranges into the central part of the management area. These flows finally evaporate and disappear into the ground. The mean annual rainfall is less than 200mm. There is no surface water licensing.

Vital Statistics:

Please note:

No data were supplied about total surface water use for some river basins (eg. unregulated basins in NSW).

A four-class classification system was developed to provide a simple method to communicate the status of the use and allocation of Australia's water resources in relation to sustainable water management.

It is important to recognise that adequately quantifying a sustainable flow regime or sustainable yield and consequent operating rules is a complex matter. State, Territory and scientific agencies continue to develop and apply methods and measures for determining sustainable flow regimes and sustainable yields.

This categorisation provides a general guide only. Please refer to the State and Territory Overview and Technical reports for detail on the analysis methods used.

* Water use as a percentage of sustainable flow regime (surface water) and sustainable yield (groundwater)

PLEASE NOTE:

Sustainable Yield:

As this SWMA is in arid zone, the sustainable yield is estimated as 5% of the Divertible Yield. Divertible Yield was not estimated for the SWMA, and hence Sustainable Yield could not be estimated. The assumptions, method and basis for estimation of environmental flow in general are explained in the section titled 'Environmental Flow Requirement' in the NT Technical Report.

PLEASE NOTE:

Categorisation:

Categorisation was based on the level of surface water resource development which is very low.

How saline are the surface water resources in the Warburton (NT) surface water management area?

No data were available about the salinity of surface water resources in the Basin / SWMA for the Australian Water Resources Assessment 2000.

There were no major water storages reported in this area as part of the assessment
