These releases will be to provide water supply and environmental flow for up to five days, which is usually supplied through the cone valve.

One radial gate will be opened by a small increment, to allow for the target flow of water supply as needed.

These operational releases are not expected to have downstream impacts and are being carefully managed by dam operators and flood engineers to match release volumes typically made from the cone valve, which can range from approximately 300 ML to 600 ML per day, depending on demand from the Water Treatment Plants, but more recently have ranged from 1000 ML to 3000 ML due to water quality and dam inflows.

Should releases from the flood mitigation storage compartment at Wivenhoe Dam be required during this time, we’ll issue community notifications through our regular channels. Stay up to date on our dam release update page: https://www.seqwater.com.au/dam-release-update
