Goulburn-Murray Water (GMW) is a statutory Corporation constituted by Ministerial Order under the provisions of the Water Act 1989 (the Act). An Independent Board of Directors (the Board) governs GMW. The Board operates under part 6 of the Act and reports annually to the Minister for Water and the Treasurer.

We have functions and powers under the Act to provide, manage and operate an irrigation district (pursuant to section 221 of the Act), a water district (pursuant to section 163 of the Act) and a waterway management district (pursuant to section 189 of the Act).

Goulburn-Murray Water is Australia’s largest rural water corporation.

We manage, store and deliver water through approximately 10,000 km of delivery and drainage infrastructure to more than 25,000 active customers in northern Victoria.

We manage 23 water storages that can hold approximately 11,400 GL of water and also have responsibility for managing more than 100,000 hectares of public land surrounding our storages.

We manage 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, stretching from Corryong in the east down river to Nyah. This area supports diverse agricultural commodities including dairy, cropping, horticulture, beef and sheep.

Goulburn-Murray Water is the northern Victorian Resource Manager appointed by the Minister for Water and is responsible for making the seasonal determination for all northern Victorian declared water systems. We are a partner in the Victorian Water Register, which manages more than $7 billion of water entitlements and over $300 million in water share and allocation trade for Victoria. 

We are Victoria’s largest inland boating authority and manage boating and recreational activities across the majority of our storages.

In addition, we service and supply a diverse range of Urban Water Authorities, Environmental Water Holders, Catchment Management Authorities (CMA) and the Murray-Darling Basin Authority (MDBA).

Goulburn-Murray Water maintains recreational infrastructure and services at 23 storages, managing safe boating access at 16 of these. To varying degrees, all the dams managed by GMW are available to the public for recreational use such as boating, fishing and swimming.

The complementary services portfolio includes 724 houseboat licences, over 50 public boat ramps, 673 occupational licenses, 245 agricultural licences, 13 caravan park leases and 62 community/club leases. The 85 recreation reserves located around GMW and MDBA storages are funded by GMW, the MDBA and partly or fully by local government.
