Flooding contributes to major improvements in the long-term health of the Murray–Darling Basin and dissolved organic carbon-rich water (blackwater) can result via natural processes.

As COVID-19 challenges our way of working and communicating, the Murray–Darling Basin Authority remains committed to serving Basin communities and the nation with as little disruption as possible in the coming weeks and months. Implementing the Basin Plan and managing the River Murray on behalf of Basin governments continues to be our priority.

The New South Wales Government and the Australian Government requested the Murray–Darling Basin Authority to undertake a review of Nimmie-Caira’s estimated contribution to the water recovery target.

Complementary measures include a range of non-flow natural resource management activities such as installation of fishways, fish diversion screens, release of the carp herpes virus, investments to address cold water pollution and riparian management activities and habitat restoration. 

This document is the last annual implementation report of the Basin Salinity Management Strategy (BSMS) that was implemented by the MDBA and Basin governments from 2001 to 2015.

Managing flows, wherever possible, can help to mitigate salinity, turbidity, fluctuating water temperature and dissolved oxygen shortages.

The Murray–Darling Basin Authority’s (MDBA) position statement for managing groundwater in the Murray–Darling Basin outlines the expectations of the MDBA in regard to sustainable management of groundwater resources.

The Salinity Impact Rapid Assessment Tool (SIMRAT) is one of a suite of tools developed for estimating salinity impacts of accountable actions to support Basin Salinity Management Strategy (BSMS) objectives. SIMRAT was developed for the Murray– Darling Basin Commission (MDBC) and accredited in 2005 for assessing salinity debits due to water trades to greenfield irrigation sites within the Pilot Interstate Water Trading area (i.e. Mallee region of Vic, NSW, SA).

The General Review of Salinity Management established the current understanding of the salinity risk to the shared water resources in the Murray–Darling Basin and assessed the future salinity risk within the context of a changed flow regime anticipated by the implementation of the Basin Plan.

The Murray–Darling Basin Authority (MDBA) has recommended an adjustment of 605 gigalitres (GL) to the Sustainable Diversion Limits in the southern Basin to the Deputy Prime Minister and Minister for Agriculture and Water Resources, Barnaby Joyce.
