Current water releases for the environment

Water releases for the environment in the Thomson, Macalister, Tanjil and Latrobe rivers

Many rivers and wetlands have been modified to provide water for towns, industry and food production. This can mean about half of the natural flow into rivers and wetlands is removed each year.

Water for the environment has been set aside in the Thomson Reservoir, Lake Glenmaggie and Blue Rock Reservoir. This water is released to support the animals and plants of the Thomson, Macalister, Tanjil and Latrobe rivers to live, feed and breed.

Water releases are planned in these rivers in April and May 2017. These releases will trigger the migration and breeding of Australian grayling, a vulnerable migratory fish species.

Releases will be controlled to increase and decrease gradually. They will be well 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: 19 to 30 April, 2017
Highest flow and water level: 800 megalitres per day; 0.6 metres
Dates when flow is highest: 22 to 25 April, 2017

Macalister River below Lake Glenmaggie
Start and end dates of water release: 21 to 29 April, 2017
Highest flow and water level: 350 megalitres per day; 0.56 metres
Dates when flow is highest: 22 to 26 April, 2017

Tanjil River at Tanjil South
Start and end dates of water release: 19 April to 1 May, 2017
Highest flow and water level: 800 megalitres per day; 1.6 metres
Dates when flow is highest: 23 to 24 April, 2017

Latrobe River at Thoms Bridge
Start and end dates of water release: 25 April to 30 April, 2017
Highest flow and water level: 1300 megalitres per day; 1.15 metres
Dates when flow is highest: 26 to 28 April, 2017

This is an estimate and may change slightly due to natural losses in the river and travel time of these water releases, particularly in the lower sections on the river.

Please be careful near these rivers at these times
