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.

The Barmah–Millewa Reach, or the narrowest parts of it, are referred to as the ‘The Narrows’. It was previously referred to as Barmah Choke.

A large number of water access rights are traded throughout the Basin. These rights all have different characteristics including priority, reliability and form of take.

To continue to support the efficient functioning of water markets in the River Murray system, the Murray–Darling Basin Authority and water agencies and authorities from New South Wales, Victoria and South Australia have been investigating better ways to make trade adjustments.

There is reduced flow of water through the Barmah–Millewa Reach caused from the build-up of sand on the riverbed.
