Reclassification of licence

 Surface water allocation announcements during 2009–10 have been restated because:

  1. the Bureau of Meteorology (the Bureau) reclassified the Lake Argyle Village licence (SWL166420) to urban supply. This reclassification caused Line item 21.1 Surface water allocation announcements to be overstated by 75 ML
  2. the Bureau changed the water accounting treatment of Tropical Forest Service licence (SWL162772). Previously, the liability was not recorded as the licence was deemed to be an unregulated due to the status of the Dunham River. However, the Tropical Forest Service licence is regulated as the present obligation can be discharged from the available water source at Arthur Creek Dam.
