The Mulwala Canal is an irrigation canal in the southern Riverina region of New South Wales, Australia. It is the largest irrigation canal in the Southern Hemisphere. 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.
