5.1 Surface water allocation remaining

Supporting information

The volume recognised in the water accounting statements (23,801 ML) represents the volume of surface water allocation remaining for individual user licence entitlements at the end of the 2011–12 year. 

The Department of Water administers 100 separate licences in this category held by individual licensees. Licences primarily relate to water sourced from the main Ord River channel, Upper Ord River, Dunham River and King River for the agricultural and mining sectors.

Generally, the water management year for private users commences on the date the licence is issued. Consequently, there are a high number of private water users whose licence anniversary falls outside the standard water year (1 July–30 June). As a result, the allocation remaining on 30 June 2012 is relatively high (more than two thirds of the allocation announcement).
