Trade out of the Broken is allowed when the Broken system’s inter-valley trade (IVT) account owes less than 1,500 megalitres (ML) to the Goulburn system.

Goulburn-Murray Water has advised that, as Lake Nillahcootie has filled and is now spilling, the undelivered opening balance of 1,162.6 ML in the Broken IVT account will be written off and reduce the Broken IVT account balance to around 337.4 ML.

As a result, around 1,160 ML of Broken Trade Out opportunity will become available. This opportunity will open at 10 am on Wednesday 19 August 2026, and will operate on a first-in, first-served basis.

Trading opportunities may increase again later in the season when water is delivered from the IVT account or if trade occurs back into the Broken system.
