The operations and assets of the River Murray system, including Dartmouth Dam, are controlled by a joint venture made up of the Australian, New South Wales, Victorian and South Australian governments.

2023 MDBA graduates share highlights, challenges and where to next.

Water infrastructure is a term which can apply to a range of assets: dams, weirs, flood levees and embankments, fishways, regulators, pump stations, managed aquifer recharge ponds and injection wells and desalination plants.

The 2023 JS Collings Trophy for excellence in maintaining major water management infrastructure on the River Murray has been awarded to Mildura Weir by the Murray–Darling Basin Authority (MDBA).

To understand how fish are counted in fishways, first it is important to understand why we want to count these fish in the first place.

Since 1922, when the first weir was constructed, there have been efforts to help fish move through the waterways. Our timeline shows the progress of the fishway infrastructure.

Fishways are important for the passage of fish through barriers such as weirs, to allow them to migrate up and down a river. There are many fishways along the River Murray. Learn about how they work, their types, locations, history and fish movement.

In 2019, the MDBA undertook a detailed survey of the River Murray channel through the Barmah–Millewa Reach. This revealed the presence of a very large quantity of sand on the bed of the river, something that was not expected. Since then, several further studies have been undertaken to investigate the extent and source of the sand, the rate that it is moving at and options to manage it. Reports of these studies are provided below.

We are currently undertaking airspace operations at Dartmouth Dam. Releases will reduce from near 8,900 ML/day to target 7,000 ML/day (measured at Colemans gauge).

Landholders and river users, including pumpers, on the Mitta Mitta River are advised to take into account the forecast releases of water from Dartmouth Dam and make any necessary adjustment to their river activities.
