Water status: Water Storage

/

The volume of water in storage as a percentage of the accessible storage capacity. Note that the percentage full may exceed 100% due to floods for example.

Related: accessible storage capacity

Synonym: percentage full

This definition applies to:

The volume of water that a water storage can hold between the minimum supply level and full supply level; equal to the total storage capacity excluding the dead storage capacity. It is the sum of this capacity that is reported for a collection of water storages. See the water storage diagram for more information.

Synonym: capacity

This definition applies to:

The volume of water stored at a particular time and date. It excludes the dead storage volume and hence is the volume of water that can be accessed under normal circumstances without the installation of additional infrastructure. See the water storage diagram for more information.

Synonym: volume

This definition applies to:

The sum of volumes held in water storages that are within a region or associated with a city or system. Each water storage can contribute up to its accessible storage capacity to the aggregated volume. In some cases only a portion of the water in a storage is shared with a city or system.

Australian Height Datum

The datum that sets mean sea level as zero elevation. Mean sea level was determined from observations recorded by 30 tide gauges around the coast of the Australian continent for the period 1966–1968. See Geoscience Australia for further information.

This definition applies to:

The date on which the published measurement was observed.

This definition applies to:

The portion of total storage capacity that is equal to the volume of water below the level of the lowest outlet (the minimum supply level). This water cannot be accessed under normal operating conditions. See the water storage diagram for more information.

This definition applies to:

Representation of the catchments of major surface water drainage systems, generally comprising a number of river basins. In Australia, 12 drainage divisions were first defined in the 1960s by the Australian Water Resources Council. Australian drainage division boundaries were revised by the Bureau in 2010 in line with the creation of the Australian Hydrological Geospatial Fabric (Geofabric) based on the 9 second Digital Elevation Model.

Any water storage that has a total storage capacity of 1000 million litres or more.

This definition applies to:

The lowest water level to which a water storage can be drawn down (0% full) with existing outlet infrastructure; typically equal to the level of the lowest outlet, the lower limit of accessible storage capacity. See the water storage diagram for more information.

Minimum Supply Level

This definition applies to:

The volume of water in storage as a percentage of the accessible storage capacity. Note that the percentage full may exceed 100% due to floods for example.

Related: accessible storage capacity

Synonym: % full

This definition applies to:

The area of the water surface, typically measured when the water storage is at full supply level.

This definition applies to:

The entire volume of water contained by the water storage at full supply level; equal to the sum of the accessible storage capacity plus the dead storage capacity. See the water storage diagram for more information.

Synonym: accessible storage volume

This definition applies to:

The height of water in a water storage at a particular time and date measured from the minimum supply level. See the water storage diagram for more information.

This definition applies to:

The elevation of the water surface at a particular time and date, measured relative to a specified datum.

This definition applies to:

A hydrological feature in which water is stored. Surface water storages include natural and artificial ponds, lakes, reservoirs and lagoons, also the bodies of water held behind weirs and dams.

In the National Water Account, surface water storages include only artificial or natural water storages connected to rivers, which primary purposes are medium to long term water storage to service surface water access rights. These storages can be managed by an organisation to provide water to an urban water system.

This definition applies to:

The year when the water storage structure was completed, as advised by the water storage owner or operator.
