Current water releases for the environment

Water for the environment to be released in the Thomson and Macalister rivers.

Water for the environment, will be released from Thomson Reservoir and Lake Glenmaggie into the Thomson and Macalister rivers on the following dates.

These water releases are timed top trigger the downstream migration and spawning of tupong and Australian bass. Both species need high flows in the winter months to migrate downstream to the estuary or ocean to spawn.

The release will be controlled to increase and decrease gradually and will be well below minor flood levels and will not impact on properties or assets next to the river.

The expected conditions in these rivers are:

Macalister River at Glenmaggie tail gauge
Start and end dates of water release: 23 July to 3 August, 2018
Highest flow and water level: 700 megalitres per day; 0.7 metres
Dates when flow is highest: 25 July to 29 July, 2018

Thomson River at Coopers Creek
Start and end dates of water release: 2 August to 12 August, 2018
Highest flow and water level: 800 megalitres per day; 0.6 metres
Dates when flow is highest: 4 August to 7 August, 2018

Details provided are estimates. They may change slightly due to operational changes, natural losses in the river and travel time of the water release, particularly in the lower sections of the river.

Please take all reasonable care when you are doing anything near the river at these times.
