About Us

GMW is Australia's largest rural water corporation managing around 70 per cent of Victoria's stored water resources, around 50 per cent of Victoria's underground water supplies and Australia's largest irrigation delivery network.

Goulburn-Murray Rural Water Corporation, trading as Goulburn-Murray Water, is a statutory Corporation established under the provisions of the Victorian Water Act. Goulburn-Murray Water (GMW) manages water related services in a region of 68,000 square kilometres, bordered by the Great Dividing Range in the South and the River Murray in the North and stretching from Corryong in the East down river to Nyah. We have more than 39,000 customers in Northern Victoria.

GMW manages both regulated and unregulated river systems that flow into the Murray and administers groundwater within this area.

GMW also operates a number of storages and weirs on behalf of the MDBA, operates salinity mitigation works on the Murray downstream of Nyah, and is the Victorian constructing authority for the Murray-Darling Basin Authority (MBDA).

GMW is the Victorian Resource Manager appointed by the Minister for Water and has been given responsibility for making the seasonal determination for all Northern Victorian declared water systems.

FAQs
What is blue-green algae?
Blue-green algae are naturally occurring bacteria in our waterways and storages. Hot weather and low slow flowing water provide peak conditions for algae levels to increase in our rivers, streams and channels. Blue-green algae contain toxins that are harmful to humans and animals. It is not known how long the blue-green algae will remain at high levels however; cool, cloudy and windy weather will help to reduce blue-green algae levels.
How are blue-green algae detected?
GMW tests water on a weekly basis during times of peak blooms. Samples are sent to a laboratory, where the blue-green algae are identified and counted under a microscope. As soon as it is detected, GMW issues alerts and advice through its website, hotline and the media.
Can blue-green algae be removed?
Blue-green algae are very small and GMW cannot remove them. Chemicals that kill blue-green algae cannot be used in natural waterbodies due to their impact on other creatures that live in the water.
