Vital Statistics:

Area: 199,000 Km2
Total storage volume: no data
Total surface water use: 1,505 ML/yr
Development category: LOW DEVELOPMENT
Mean annual run-off: 0 ML/yr

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.

CategoryDevelopment status
1<30% Low development
230 - 70% Moderate development
370 - 100% Highly developed
4100% Overdeveloped

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

How saline are the surface water resources in the Gairdner surface water management area?
