Grahamstown Dam is a major off-stream earthfill Embankment dam with a controlled labyrinth spillway and baffle chute that stores water from the Williams River. The dam is located north of Newcastle, New South Wales, Australia. The dam's main purpose is water supply; it provides about 40 per cent of
the potable water for the Hunter Region; and is its largest drinking water supply dam. The impounded reservoir is called Grahamstown Lake or the Grahamstown Storage Reservoir.
