Goulburn-Murray Water

Goulburn-Murray Water (GMW) is Victoria’s largest rural water provider. It stores, manages and delivers about 70 per cent of Victoria’s stored water and around 50 per cent of its underground water supplies. It also operates Australia’s largest irrigation delivery network and manages a range of recreational facilities and services across northern Victoria, including leasing land, licensing houseboats and maintaining public amenities.

GMW has more than 21,000 customers, delivers more than 39,000 services and maintains more than $5 billion in assets. Its major customers comprise irrigators who grow food, and country customers who require water for stock, pets and gardens. It also supplies water to urban water corporations and environmental water holders, who have purchased water entitlements to maintain the health of rivers, streams and wetlands.

GMW’s service area covers about a third of Victoria. It is bordered by the Great Dividing Range in the south and the Murray River in the north, and stretches from Corryong in the east to Nyah in the west. A key part of the region is the Goulburn-Murray Irrigation District, which spans 27,000 square kilometres and is responsible for almost $6 billion of agricultural production each year.

Water resources

GMW is responsible for managing seven river basins, including the Loddon, Campaspe, Goulburn, Broken, Ovens, Kiewa and Upper Murray basins, and their associated water supply systems. Water is provided from these systems to rural customers, urban water businesses and environmental water holders that protect and improve waterway health.

GMW manages a number of historic irrigation assets, including Goulburn Weir, Lake Eildon and Dartmouth Dam, the largest capacity dam in Victoria.

Victoria’s Minister for Water has also appointed GMW to undertake the role of Northern Victorian Resource Manager. The Resource Manager makes seasonal determinations for all northern Victorian regulated river systems.
