Extraction shares are a share of the total amount of water that can be drawn from regulated rivers at a certain point over a given period. Extraction shares are used to restrict water extraction in times of high demand. The extraction share is expressed on a works licence.
Reporting against this priority output indicates that the VEWH has not completed all formal operating arrangement documents between storage managers, waterway managers and land managers (where applicable). This is a clear, easily interpreted and measurable output.
Operating arrangements, including those related to channel capacity, are a requirement in bulk and environmental entitlements (for example see Bulk Entitlement (River Murray - Flora and Fauna) Conversion Order 1999 as at 5 June 2014, that can be viewed at the Victorian Water Register). Volume 2 of the Strategic Review of the VEWH Organisational Performance page 20 notes that the operating arrangements for delivery of environmental water are being completed by the VEWH.
The lack of formal documentation of current operating arrangements was discussed in an interview with a storage manager. The storage manager recognised the value of the arrangements. However, they believed that the excellent communication and coordination role played by the VEWH meant that effective water management was being achieved even though not all arrangements were in place. Informal arrangements are in place and well understood.
To date the lack of formal documentation has not had significant consequences. Existing processes appear to be meeting the requirements of the action. However, the VEWH should endeavour to complete formal operating arrangements required by bulk and environmental entitlements.
