Supplementary flow events are announced periodically during the season when high flow events occur, with the period of extraction and volume of water to be extracted determined based on the rules as set out in the water sharing plans. Available Water Determinations are made once at the start of the year and unless there is a management change due to the growth in use strategy it is maintained at the maximum value prescribed in the plan generally 100 per cent of share component.

Guidelines for setting Available Water Determinations are set by Part 8 Division 2 of the Water Sharing Plan.
