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.

Sam O’Rafferty is an emerging young leader who is passionate about solving water efficiency problems for growers.

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

The Murray–Darling Basin Authority (MDBA) operates the River Murray to share water between New South Wales, Victoria and South Australia, as required under the Murray–Darling Basin Agreement. To undertake this work the MDBA has built, maintained and operated a hydrological model of the River Murray.

The delivery of water from the major storages in the Upper Murray to irrigators throughout the Basin can be challenging. There are a number of constraints that impact water delivery to below the Barmah Reach, such as the length of time required to deliver water and the amount of water that can be delivered at any one time.
