It is the largest irrigation canal in the Southern Hemisphere.

[2] The canal, starting at Lake Mulwala, diverts water from the Murray River across the southern Riverina plain to the Edward River at Deniliquin.

The channel has an offtake capacity of 10,000 megalitres (ML) per day and annually supplies over 1,000,000 ML to 700,000 hectares (1,700,000 acres) in the Murray Irrigation Area.

[4] As well as water for agriculture, the canal also provides water for the southern Riverina towns of Berrigan, Finley, Bunnaloo and Wakool.

The power station, with a generating capacity of 2.5 MW of electricity, is Australia's first hydroelectric power station on an irrigation canal.
