Glennies Creek Dam is a minor ungated concrete faced curved earth and rockfill embankment dam with an uncontrolled rock cut spillway across the Glennies Creek, upstream of Singleton, in the Hunter region of New South Wales, Australia. The dam's purpose includes flood mitigation, irrigation, water supply and conservation. The impounded reservoir is called Lake Saint Clair.

Glennies Creek Dam was created through enabling legislation enacted through the passage of the Glennies Creek Dam, 1979 (NSW). The Act appropriated AU$30 million as the estimated cost of construction of the dam.[1]
