Murray–Darling Basin

14.7.1 Allocation diversion of regulated flows – S&D water access entitlement

Supporting information

The volumetric value for the line item is 42,934 ML. The line item reports on diversions made using a specific stock and domestic entitlement. In New South Wales, this entitlement is used for diversion for stock and domestic purposes when the property is not adjacent to the river. If the property is adjacent to the river, the abstraction occurs under a statutory basic right (see Line item 14.5.1 Surface water diversion – riparian right). The following table provides a breakdown of the line item value.

New South Wales data include the domestic and stock, domestic and stock (domestic) and domestic and stock (stock) diversions.

Victoria does not have entitlements of a specific stock and domestic class. See Line item 14.7.9.7 Allocation diversion of regulated flows – other lumped holders, for values lumped for all entitlement classes.

Uncertainty

See the above table entitled ’Allocation diversion of regulated flows made under stock and domestic water access entitlement in the Murray–Darling Basin region in 2009–10’ for the uncertainty estimates.

Approximations, assumptions, caveats/limitations

Uncertainty reported for diversion at the abstraction point accounts for possible errors in the data collection process.
Uncertainty of diversion at the diversion point: a single metered abstraction point may provide water to a range of users, under various types of entitlements (e.g. stock and domestic class). When this happens, the jurisdiction may split the metered abstraction into several classes of entitlements or types of users, according to priority rules governing the entitlements. This split has an inherent uncertainty that is not considered here.
