Report to assist community consultation
The Barwon-Darling: Floodplain harvesting in water sharing plans – Report to assist community consultation report (PDF, 850 KB) aims to assist the community in understanding the proposed types of rules for floodplain harvesting access licences in the Barwon-Darling. It also provides a summary of the other three technical reports and explains the interaction between the rules, modelling, and the expected downstream outcomes once they are put in place.
The NSW Floodplain Harvesting Policy requires that individual entitlements in regulated river systems and the Barwon-Darling unregulated river water source will be informed by a capability assessment that considers the works used for floodplain harvesting and the opportunity to access floodplain flows based on location and climatic variability. This capability assessment is undertaken through river system models.
Building the river system model for the Barwon-Darling Valley unregulated river system: Model Build Report (PDF, 4.1 MB) describes the development of the Barwon-Darling Valley river system model. The model was developed using multiple lines of evidence and best available industry data. The report provides evidence and assessments to demonstrate that the model is fit for purpose.
Floodplain harvesting entitlements for the Barwon-Darling unregulated river system: Model Scenarios Report (PDF, 821 KB) describes how the model of the Barwon-Darling was used to estimate the basin diversion limit, and to subsequently estimate individual floodplain harvesting entitlements.
The modelling reports for the Barwon-Darling have been independently peer-reviewed – Barwon-Darling reports review – summary May 2022 (PDF, 142 KB).
Downstream effects report
The NSW Floodplain Harvesting Policy will restrict the volume of water that can be taken from the floodplain providing gains to the system through foregone diversion.
Any gains in upstream systems such as the Barwon-Darling Valley will translate into the downstream with additional volumes originating in each of the Barwon-Darling tributary valleys contributing to connectivity between the broader northern Basin system and provision of increased flows towards Menindee Lakes and into the Murray River.
Modelled downstream effects of licensing floodplain harvesting in the Barwon-Darling Report (PDF, 4.1 MB) quantifies the potential downstream impacts of these increased flows. This report includes work completed for the NSW Border Rivers and the Gwydir and Macquarie valleys.
