Allocation limit
Annual volume of water set aside for licensed use from a water resource.
Aquifer
A geological formation or group of formations able to receive, store and transmit significant quantities of water.
Crown
Vested in His Majesty which is not for the time being dedicated to any public purpose, or subject to any grant, lease, licence, contract, or engagement made by or on behalf of His Majesty.
Entitlement
The quantity of groundwater permitted to be abstracted by a well (bore) licence, usually specified in kilolitres/year (kL/year).
Groundwater
The water that occurs in pore spaces and fractures in rocks beneath the ground surface.
Groundwater is contained in the following types of aquifer:
- The unconfined aquifer (also referred to as a 'superficial', 'surficial' or ‘non-artesian’ aquifer) is the aquifer nearest the surface, having no overlying confining layer. The upper surface of the groundwater within the aquifer is called the watertable.
- A confined aquifer is an aquifer lying between confining layers (such as clay, coal or rock) containing water under pressure.
- An artesian aquifer is a confined aquifer under hydraulic pressure that causes water levels to rise naturally to the ground surface. In all areas of the State, the use of artesian water is only permitted by the approval of a groundwater licence.
Groundwater and surface water areas
All the boundaries that are proclaimed under the Rights in Water and Irrigation Act 1914 and used for water allocation planning and management.
Groundwater resource area
All the boundaries that are proclaimed under the Rights in Water and Irrigation Act 1914 and used for water allocation planning and management.
Hectare (ha)
A surface measure of area equal to 10,000 square metres or approximately 2.47 acres.
Intensive
In relation to stock watering, intensive (conditions) means conditions in which the cattle or stock:
- are confined to an area smaller than that required for grazing under normal conditions
- are usually fed by hand or by mechanical means.
Letter of undertaking
A letter issued to the applicant stating that a water licence will be granted when all the criteria outlined in the letter are met by the applicant (this usually includes proof of legal access).
Non-artesian well
A well (bore), including all associated works, from which water does not flow or has not flowed naturally to the surface but has to be raised or has been raised by pumping or other artificial means.
Proclaimed area
Proclamation is a legal process that makes managing water resources the Department of Water and Environmental Regulation’s responsibility. In proclaimed areas, under the Rights in Water and Irrigation Act 1914, it is illegal to take water from a watercourse or groundwater aquifer without a licence or a conferred right (e.g. exemption, riparian right).
Proclamation
A legal process that allows the Department of Water and Environmental Regulation to regulate the taking of water in certain areas under the Rights in Water and Irrigation Act 1914.
Recoup
In some circumstances, the ‘Unused Water Entitlement’ may be 'recouped' by the department if not been taken (used) for more than three consecutive years, unless otherwise specified in licence conditions or operating strategies or agreed development timeframes.
Spring
Water rising naturally to and flowing over the surface of the land. This does not include the discharge of underground water directly into a watercourse, wetland, reservoir or other water body. In some circumstances, the use of spring water may be exempt from water licensing in proclaimed resource areas.
Sensibly-diminished
Noticeable impact on downstream users or to the environment.
Subarea
A sub-division within a proclaimed groundwater resource area, defined for the purpose of managing the allocation of groundwater resources.
Surface water
Water flowing or held in waterways or wetlands on the surface of the landscape.
Surface water resource area
Area boundaries (generally hydrologic basins or parts of basins) defined by the Department of Water and Environmental Regulation proclaimed under the Rights in Water and Irrigation Act 1914 and used for water allocation planning and management.
Take
In relation to water, under the Rights in Water and Irrigation Act 1914, means to remove water from, or reduce the flow of water in, a watercourse, wetland or underground water source, including by:
- pumping or siphoning water
- stopping, impeding or diverting the flow of water
- releasing water from a wetland
- permitting water to flow under natural pressure from a well
- permitting stock to drink from a watercourse or wetland
- storing water during, or ancillary to, any of those processes or activities.
Unused water entitlement
Part or all of the licensed annual water entitlement that has not been taken (used) for more than three consecutive years, unless otherwise specified in licence conditions or operating strategies or agreed development timeframes.
Watercourse
A river, stream or creek in which water flows in a natural channel, whether permanently or intermittently.
Watertable
The saturated level of the unconfined groundwater. Wetlands in low-lying areas are often seasonal or permanent surface expressions of the watertable.
Wetland
A natural collection of water, whether permanent or temporary, on the surface of any land and includes:
- any lake, lagoon, swamp or marsh
- a natural collection of water that has been artificially altered
but does not include a watercourse.
