State water recovery – independent review reports

An independent review of the planning assumptions and calculation methodologies used by the Australian Capital Territory (ACT) to determine the long-term diversion limit equivalence (LTDLE) factor for an entitlement registered to the Commonwealth Environmental Water Holder.

The review found the methods and assumptions upon which the factor is based are appropriate for the ACT water resource management context, best available at the time, and endorses the factor developed by the ACT.

A report outlining the findings of an independent review of the methodology and approach used by New South Wales for the derivation of the revised Long Term Diversion Limit Equivalence (LTDLE) factors, as outlined in The Technical Paper: NSW updated factors for water recovery.

The report concludes that the method used is appropriate in NSW for determining and accounting the volumes of water recovered. The report found that the methods used incorporated the conditions and assumptions used to inform the BDL model runs consistent with the Basin Plan, is based on best available data and information, and treated entitlement classes appropriately. The report also found that the method has been applied in a consistent manner across the NSW valleys in the Murray−Darling Basin.

An independent review of the Victorian method and planning assumptions for long term diversion limit equivalence (LTDLE) factors in the Murray-Darling Basin.

A report outlining the findings of an independent review of the planning assumptions and the calculation methodologies used by Victoria to determine their Long Term Diversion Limit Equivalence (LTDLE) factors. 

The review endorses the approach taken by Victoria to use their BDL models and planning assumptions inherent in these models to determine LTDLE factors. 

A report outlining the findings of an independent review of the methodology and approach used by South Australia for the derivation of the revised Long Term Diversion Limit Equivalence (LTDLE) factors.

The review endorses the LTDLE factors presented by South Australia. The methods and assumptions upon which the factors are based have been reviewed and are considered by the reviewers to be the best available at the current time.

A report outlining the findings of an independent review of the methodology and approach used by Queensland for the derivation of the revised Long Term Diversion Limit Equivalence (LTDLE) factors for both surface water and groundwater entitlements.

The review endorses the LTDLE factors developed by Queensland. The methods and assumptions upon which the factors are based have been reviewed and are considered by the reviewers to be the best available at the current time.
