Current water releases for the environment

Water for the environment is being released in the Thomson and Macalister rivers.

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

These water releases are timed to trigger the upstream migration of juvenile native diadromous fish, eel and lamprey species. These species need high flows followed by increased base flows in the spring months to migrate upstream from the estuary and back into freshwater environments.

Flows will also provide water to in channel aquatic vegetation as well as reduce the number of terrestrial saplings, shrubs and bushes that may be growing in the river channel.

Timing these flows together provides benefits to the lower Latrobe River.

The releases will be controlled to increase and decrease gradually and will be below minor flood levels and will not impact on properties or assets next to these rivers.

The expected conditions in these rivers are:

Thomson River at Coopers Creek
Start and end dates of water release: 31 October to 30 November, 2018
Highest flow and water level: 800 megalitres per day; 0.6 metres
Dates when flow is highest: 3 November to 6 November, 2018

Macalister River at Glenmaggie tail gauge
Start and end dates of water release: 2 November to 25 November, 2018
Highest flow and water level:
700 megalitres per day; 0.7 metres
Dates when flow is highest:
5 November to 25 November, 2018

Details provided are estimates, they may change due to operational reasons, rainfall, natural losses in the river and/or travel time of the water release, particularity in the lower sections of the river.

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

Latrobe and Tanjil rivers

Releases of water for the environment to the Tanjil and Latrobe rivers have been stopped due to recent rainfall in the catchment. Flows in the Latrobe River over coming days are expected to be sufficient to meet the environmental objectives of the previously scheduled releases.

Latest river heights for the Latrobe, Thomson and Macalister catchments are available from the Bureau of Meteorology website.
