Modelling that was used to inform the development of the connectivity actions in the Western Regional Water Strategy.

Modelling base case provides the diversions under current conditions (Water Sharing Plan rules). The base case provides daily flows and diversions for the period 1895 to 2020 for the Barwon-Darling and the following regulated tributary valleys

• NSW Border Rivers

• Gwydir

• Namoi

• Macquarie

Preliminary modelling analysis (bookend analysis) done for the Western Regional Water Strategy to understand the upper limit of possible connectivity benefits from imposing water restrictions in the Barwon-Darling and upstream regulated tributary rivers. This modelling assessed the change in daily flows from restricting all supplementary access in the tributary valleys, as well as Class A, B and C access in the Barwon-Darling.
