Barrage gates to remain open

ALL 18 gates of the Fitzroy River barrage will remain open until the flow of the river slows considerably, according to the Rockhampton Regional Council.

The Fitzroy Barrage gates are controlled automatically to open and close as required to maintain the upstream storage level at a pre-determined level in accordance with the Queensland Government regulated operating rules for the Barrage Storage.

The 18 gates will open at different levels between 0.3 and 2.1 metres in order to control and maintain the upstream storage level.

Three water level sensors are used to ensure that the storage level is controlled with a high degree of precision and reliability.

If the upstream river level continues to rise after all 18 gates have opened to 2.1 metres, all the gates will then automatically lift up out of the water to the top of the Barrage and remain clear of the water until the river level drops.

It is normal to see the Barrage gates partly submerged during low or minor flow events or alternatively see the gates fully clear of the water during moderate or major flow events.

Once the river level drops the gates are then lowered using a controlled sequence of steps to ensure that the upstream storage level is again maintained at the pre-determined level.

The Fitzroy Barrage is also monitored 24 hours a day from the Glenmore Water Treatment Plant Control Room to ensure that it is operating correctly.
