5.1 Surface water allocation remaining
The volume presented in the water accounting statements (13,946 ML) represents the allocation remaining for high-reliability water shares and low-reliability water shares in the Melbourne region. According to Southern Rural Water's Werribee & Bacchus Marsh Allocation Method, any unused allocation at the end of the season (30 June) will be part of the opening allocation at the start of the following season (1 July).
A large portion of allocations made during the 2010–11 year were left unused at the end of the period due to the wet year in the region, and relatively low diversions.
The surface water allocation remaining was calculated as shown in the following table:
|Opening balance (30 June 2010)||937|
|Closing balance (30 June 2011)||13,946|
Details of the allocation model are available on the Southern Rural Water website.
