In the Australian Capital Territory, no formal allocation announcement is made to extract water from storages and the allocation announcement for the year is assumed to be equal to the allocation diversion. Therefore, allocation remaining (carryover) will be shown as zero.

New South Wales data includes the carryover volume for the major and local water utility water access entitlement class. This line item does not contain the allocation remaining for high-security town water supply; see Line item 8.1.2.4 Allocation on regulated flows remaining – high-security, urban holder.

Allocations remaining for several New South Wales regions were negative volumes because of advance drawing. Allocations remaining for these regions are reported as zero for this line item while advance-drawing volumes are reported in Line item 7.6.

South Australia allocation remaining for urban class is reported in Line item 8.1.2.4.

No information is available for Victoria: see Line item 8.1.9.6 Allocation on regulated flows remaining – other lumped holders.

Quantification approach   


Data source

Australian Capital Territory: Water Audit Monitoring Report 2009–10 (30 November 2010).

New South Wales: NSW Office of Water’s Water Accounting section.

Queensland: Water Audit Monitoring Report 2009–10 (31 January 2011).

South Australia: Water Audit Monitoring Report 2009–10 (22 February 2011).

Victoria: Water Audit Monitoring Report 2009–10 (19 January 2011).

Note: water audit monitoring report (WAM) data are stored in the Murray–Darling Basin Authority (MDBA) HYDRO database.

Data provider

Method

  • Allocation remaining (carryover) is calculated by the states.
  • Australian Capital Territory allocation remaining is not available for the urban water access entitlement and therefore all allocation remaining at the end of the year is shown as zero.

Uncertainty

WAM-sourced data does not have an uncertainty information on allocation announcement. The uncertainty of the remaining data are shown in the above table entitled ‘Allocation/claim on regulated flows remaining within the region – urban water access entitlement/arrangement’.
