Water resources - Overview - Western Australia
Basin & Surface Water Management Area: Sandy Desert
Introduction
Name: Sandy Deser
Description: Central upper catchment, arid climate. Natural vegetation tree and shrub steppe. Land use Crown Land, National Park and some lead mining.
Vital Statistics:
| Area: | 404,325 Km2 |
|---|---|
| Total storage volume: | no data |
| Total surface water use: | 0 ML/yr |
| Development category: | LOW DEVELOPMENT |
| Mean annual run-off: | 0 ML/yr |
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.
| Category | Development status | ||
|---|---|---|---|
| 1 | <30% | Low development | |
| 2 | 30 - 70% | Moderate development | |
| 3 | 70 - 100% | Highly developed | |
| 4 | 100% | Overdeveloped |
* Water use as a percentage of sustainable flow regime (surface water) and sustainable yield (groundwater)
PLEASE NOTE:
Sustainable Yield:
Sustainable yields are considered nominal only and no detailed calculation of these figures has been undertaken.
PLEASE NOTE:
Categorisation:
Categorisation for SWMA's and Sub Areas based on NLWRA classifications for 1996/97 Water Use as a percentage of Sustainable Yield.
How saline are the surface water resources in the Sandy Desert surface water management area?
Table: Surface water resource by salinity class.
| Total Volume, Divertible Yield (ML/Yr) | |
|---|---|
| Total volume (ML/yr), DIVERSION | 0 |
| <500 mg/l (ML/yr) | 0 |
| 500 mg/l (ML/yr) - 1500 mg/l (ML/yr) | 0 |
| 1500 mg/l (ML/yr) - 5000 mg/l (ML/yr) | 0 |
| 5000 mg/l (ML/yr) - 14000 mg/l (ML/yr) | 0 |
| > 14000 mg/l (ML/yr) | 0 |
