In 2012 the Basin Plan listed estimates of the average annual volumes of floodplain harvesting as components of the baseline diversion limit (BDL) in some northern Basin sustainable diversion limit (SDL) resource units. The New South Wales ‘Healthy Floodplains Project’ includes work to enable calculation of re-estimates of BDLs associated with floodplain harvesting in these northern New South Wales SDL resource units. These volumes will contribute to re-estimates of the total BDLs for all forms of take.

With the warm sunny days still upon us, this weekend is the perfect opportunity to soak up the beauty of the Murray–Darling Basin or take part in the many activities and events happening across Basin catchments and communities.

This is a review of the hydrological models that underpin the Barwon-Darling Watercourse water resource plan that was submitted to the Murray–Darling Basin Authority in June 2020. The 2 most important of these models were the Baseline Diversion Limit model and the Annual Permitted Take model. This review was prepared to assist the Murray–Darling Basin Authority in their appraisal of the Barwon-Darling Watercourse water resource plan prior to its accreditation and implementation under the Basin Plan.
