The volumetric value for the line item at the end of the 2011–12 year was 21,187,196 ML.
The line item represents the volume of water held in storages that are used to supply water for entitlements in regulated systems and for flood mitigation purposes. The volume reported for this line item includes the volume of dead storage.
Volumetric data for a number of small storages were not received at the time of compilation of this note, and are therefore not included in the following table.
A number of mid-river storages, locks, weirs and the like also support the delivery of water. These storages form part of the river channel and usually only provide very short-term supply. The volume for a number of these storages is reported in line item 1.3 Regulated river. Water may also be used from lakes and wetlands within the Murray–Darling Basin (MDB), as reported in line item 1.4 Lakes and wetlands.
Storage information is categorised according to MDB surface water resources plan (WRP) areas. Storage information on a WRP area basis is summarised in the following table. Specific details of individual storages are included in the second table.

4The volume in Lake Menindee is available for Lower Darling, Victorian Murray and South Australian Murray sustainable diversion limit (SDL) areas.
5The volume in Lake Victoria is available for Victorian Murray and South Australian Murray SDL areas.
6–7The volume in Lake Hume and Lake Dartmouth is available for NSW Murray and Victorian Murray SDL areas.
8The volume in Googong Reservoir is available for Australian Capital Territory SDL area. Therefore, the reservoir is included under that SDL area although located within New South Wales.
Bureau of Meteorology (the Bureau): Water storages, Australian Water Information System (AWRIS); Maranoa regional Council: information received for Neil Turner Weir; and NSW State Water Corporation: information for Lake Brewster.
Storage volume is measured at the start and end of the year by using gauged water level height(s) in metres Australian height datum (mAHD) for individual storages. The height measurement is converted to a volume using the storage-volume curve(s) of the storage.
Assumptions, limitations, caveats and approximations
- Storage-volume curves represent specifically surveyed parts of the water storage, and may not reflect the storage-volume relationship across the entire storage.
- Water storages are subject to sedimentation and other physical changes over time, which in turn affect the accuracy of the storage-volume curves.
The following changes resulted in the restatement of the 2010–11 year volume:
- updated information
- scope change.
The changes and their respective values are detailed in the table below:
|Segment||2012 Account volume at 30 June 2011 (ML)||2011 Account volume at 30 June 2011 (ML)||Difference due to updated information and scope change (ML)|
Updating the 2010–11 volume was due to recalculation of the Lake Brewster volume, resulting in a 40,713 ML decrease. Scope change comprised the inclusion of McCall Say, Barkers Creek, McCay, Sandhurst and Spring Gully reservoirs, resulting in a 7,021 ML increase.
