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.

Barmah–Millewa Feasibility Study wrap up from the MDBA.

The Murray–Darling Basin Authority is moving ahead with detailed design work on a suite of options to improve the movement of water through the Barmah–Millewa Reach of the Murray River.

The Barmah Choke has a default trade restriction in place. This is necessary to protect water delivery to existing water entitlement holders and maintain the river environment in the Choke.

The Barmah Choke is a naturally occurring narrow stretch of the River Murray. A default trade restriction is in place at the Choke to protect water delivery to existing entitlement holders and for environmental reasons.

In response to the declining flow capacity, the increasing risks, and the recommendation that a range of intervention measures be investigated, the MDBA instigated the Barmah–Millewa Feasibility Study (BMFS). Six options were investigated as part of the Barmah–Millewa Feasibility Study.

The Barmah–Millewa Feasibility Study investigated and assessed options for reinstating water delivery capacity in the Barmah–Millewa Reach.
