 – = Data not available

The volumes provided in the above table include trading volumes related to regulated (including supplementary entitlements) and unregulated systems for which information was available. Information on tagging of entitlements is not included in this line item. Movement of water associated with tagging of entitlements is included in line item 37.1 Surface water allocation trade within region

Total volume of entitlement trade reported in the 2011 Account for the 2010–11 year was 557,082 ML. The volume was based on available information for the 2011 Account. National Water Commission (2011) sources show that total entitlement trade volume in the region as 914,000 ML for the 2010–11 year.

Quantification approach

Data source

(1) Murray–Darling Basin Authority: water audit monitoring (WAM) data received from New South Wales (22 January 2013), Queensland (4 February 2013), South Australia (15 March 2013) and Victoria (21 March 2013), and stored in the HYDRO database; (2) Environmental and Sustainable Development Directorate of the ACT Government: entitlement database; and (3) National Water Commision's Australian Water Markets Report 2011–12 ( National Water Commission 2013).

Provided by

Bureau of Meteorology (the Bureau).

Method

WAM-supplied data were obtained from water trade registers.

Assumptions, limitations, caveats and approximations

In general all trade was occurring within sustainable diversion limit areas that are predominantly regulated or supplemented. However, in Queensland trade in both regulated (supplemented) and unregulated (unsupplemented) systems occurred.

Uncertainty information

The uncertainty estimate was not quantified.
