Water resources - Overview - Queensland
Surface Water Management Area: Gregory
Introduction
The Greory SWMA has an area of 855 sq km. The Gregory River is a coastal stream which flows into the sea south of Bundaberg.
Most of the surrounding countryside is flat with low rolling hills, except in the south west of the catchment where the Woowoonga Range is situated. To the east, the Sea View Range forms the boundary with the Isis River catchment.
The mean annual rainfall for the area is 1100 mm.
The major storage in the system is the Gregory weir (390ML) which is used to supply urban water for the Isis Shire.
Vital Statistics:
| Area: | 855 Km2 |
|---|---|
| Total storage volume: | 250,415 ML |
| Total surface water use: | 7,903 ML/yr |
| Development category: | LOW DEVELOPMENT |
| Mean annual run-off: | 150,400 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.
| 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:
No sustainable yield studies are available for this SWMA.

There is a low level of development in this SWMA with irrigated sugar cane being the main crop. A Water Allocation and Management Plan is currently being developed for this SWMA.
How saline are the surface water resources in the Gregory 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.
