About Dartmouth Dam

Dartmouth Dam is operated by Goulburn-Murray Water on behalf of the Murray-Darling Basin Authority.

It is the largest capacity dam in Victoria and the highest structure of its kind in Australia. When full, the dam stores almost 4,000,000 megalitres (ML).

Visit the MDBA Dartmouth Dam page here.


Dartmouth Dam is located downstream of the confluence of the Mitta Mitta and Dart Rivers, approximately 24 km east of Mitta Mitta in North-Eastern Victoria.


Dartmouth Dam was constructed by the Victorian Rural Water Commission on behalf of the then River Murray Commission, the forerunner to today's MDBA. Construction began in 1973 and was completed in 1979.

Construction costs were shared equally by the Commonwealth, Victoria, New South Wales and South Australia due to the role of the storage in the Murray system.

The primary purpose of Dartmouth Dam is the storage of water for irrigation and domestic and stock use in Victoria and New South Wales.

In dry seasons, the storage supplements releases from Lake Hume and increases supplies to the River Murray system.

Further Information

Lake Dartmouth offers a variety of water sports as well as recreation facilities. It is a favourite spot for fishing, especially trout

Macquarie perch (Maccas) are present, but can’t be caught or targeted by recreational fishers from any waterway in Victoria, giving wild populations the best chance to re-establish.

Inadvertently caught Maccas must be returned to the water quickly and safely.

For more information on the Victorian Fisheries Authority’s efforts to recover Macquarie perch, visit www.vfa.vic.gov.au/recoveringmaccas

Camping (with limited facilities) is permitted in designated areas around the Lake. The track from Sassafras Gap to the Eustace Creek camping area can be accessed by car, although a four wheel drive is recommended in wet conditions. The two other camping grounds can only be reached by boat.

There are good boat launching facilities but, while motor boats can be used, water skiing and house boating is not permitted. Boats are required to keep at least 700 metres away from the dam wall.  Work is being done to extend temporary boat launching facilities to enable continued boat access at low lake levels.
