Welcome to MDBA River Data.
As of 26 September 2023, the River Murray System is fully regulated for the first time since 2021. Under dry conditions, all irrigation and environmental water demands will be met by releasing water from storages.
This website aims to give an overview only of flow and storage information for the River Murray System. Please note that some sites may be off-line and no data is shown.
For information from other catchments please contact your relevant state water agency. More information is available at Who does what in the catchments.
Lake Alexandrina (Calculated) Murray
The Lower Lakes are not a consumptive storage for South Australia. Water in the lakes is a combination of South Australia entitlement flow, volume for dilution to reduce salinity and to mitigate the impact of seawater intrusion. At times, environmental water may be used in the lakes to enhance environmental outcomes and to maintain Barrage releases. Releases of water at the barrages are closely managed to optimise environmental and water quality outcomes, consistent with the Murray–Darling Basin Plan.
This is a calculated mean lake level. The calculation is based on a three day moving average from multiple sites within Lake Alexandrina. Data for individual sites can be viewed via River Murray Data.
Salinity data provided here are for the site at Milang Jetty in Lake Alexandrina. This is one of the designated salinity monitoring sites for assessing performance against salinity targets in the Basin Plan.
