Gascoyne River |
Gascoyne River Surface Water Management Area is within Western Australia and is 75,835 km2
| |
The estimate of regional water consumption was prepared by the Australian Bureau of Statistics (ABS) for the Gascoyne River Surface Water Management Area
Estimated water consumption is 4,652 ML
Other comprises approximately 50% of total water consumption; Agriculture comprises approximately 44% of total water consumption; Household comprises approximately 5% of total water consumption; Mining and Manufacturing comprise the remainder.
PLEASE NOTE: Regional estimates were derived using survey data designed to produce state- and territory-level estimates, and incorporated data from a range of other sources. The degree of confidence that can be attached to individual regional estimates is variable. In general, the estimates should be used with a moderate degree of confidence. For further details see ABS Publication 4610.0.055.002
|
The categories used for the breakdown of water consumption are as per Table 2.9
of the Water Account 2004-05. "Other" in respect of the estimated water consumption
comprises water use within the following industries:
- Water supply, sewerage and drainage services
- Electricity and gas
- Forestry and fishing
- Services to Agriculture
- "Other industries"

Surface water sustainable yield
|
The sustainable yield within this surface water management area for 2004/05 was: |
196000 ML |
