South Australia's Strategic Plan is comprised of 100 targets. These targets are specific and measurable and enable us to measure our progress towards achieving the Plan's visions and goals.

Each target is reported on through this section of the website. Data has been updated as at December 2017.

Target:

77. River Murray – salinity:

Explanatory Comments

Under Schedule B of the Murray-Darling Basin Agreement (Schedule 1, Water Act 2007 (Cth)), South Australia is accountable for actions that will change salinity in the River Murray. 

The actions are recorded as debits or credits on the Murray-Darling Basin Authority (MDBA) Salinity Registers. Actions such as irrigation development increase the salinity impacts and result in a debit on the Salinity Register, whereas actions such as salt interception, improved irrigation efficiency and rehabilitation of drainage schemes decrease the salinity impacts and result in credits on the Salinity Register.

As at November 2016 (the most recent published data), South Australia maintains a positive credit balance of $7.035 million per year on the Salinity Registers.

The Y-axis on the above graph is “Salinity cost/benefit in $m/year”, which is an MDBA approved formula used to calculate the conversion of the salinity impact in tonnes per day to a salinity cost/benefit in dollars per year for the Salinity Registers.
