Glenbawn Dam is a major ungated earth and rock fill with clay core embankment dam with concrete chute spillway plus fuse plugs across the Hunter River upstream of Aberdeen in the Hunter Valley of New South Wales, Australia. The dam's purpose includes flood mitigation, hydro-electric power, irrigation, water supply and conservation. The impounded reservoir is called Lake Glenbawn.
Glenbawn Dam was created through enabling legislation enacted through the passage of the Glenbawn Dam Act, 1946 (NSW). The Act appropriated A£1,500,000 as the estimated cost of construction of the dam.[1]
