Welcome to MDBA River Data – providing flow and storage information for the River Murray System. For information from other catchments please contact your relevant state water agency.
The site aims to give an overview only of conditions across the whole of the River Murray System and some sites may be off-line due to flood inundation and no data is shown.
For the latest river heights please refer to Australia Rainfall and River Conditions (bom.gov.au) For the latest flood watches and warnings see National Warnings Summary (bom.gov.au).
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.
