New South Wales data includes the domestic and stock, domestic and stock (domestic) and domestic and stock (stock) licence classes. Usually the unused balances are forfeited at the end of the year. Overdraws against this class must be repaid in the future: see Line item 7.6 Non-physical water asset – other lumped for advance diversion of surface water allocation – remaining.

South Australian data are included in Line item 26.1.2.5.

For Victoria see Line item 26.1.9.7 Adjustment and forfeiture of allocation on regulated flows – other lumped holders, for values lumped for all entitlement classes.

  New South Wales: New South Wales 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 (WAM) report data are stored in the Murray–Darling Basin Authority (MDBA) HYDRO database.

Data provider

MDBA.

Method

Adjustment and forfeiture is as calculated by the states.

Uncertainty

WAM-sourced data does not have any uncertainty information on allocation remaining. The uncertainty of the remaining data are shown in the table provided in ‘Supporting information’.

Approximations, assumptions, caveats/limitations

  • Uncertainty reported by New South Wales Office of Water accounts for possible errors in the quantification of diversion and in the data-handling processes.
