Glenbawn Dam is a popular inland sport and recreation destination near Scone, offering year-round attractions for water sports and fishing enthusiasts, nature lovers, bushwalkers, campers and picnickers. The dam has one of the largest rock-fill embankment walls in Australia, 100 metres high and 1.1 kilometres long. The main purpose of the dam is to supply water for irrigation, power generation, stock, industry and household needs in the Hunter Valley, and provide flood mitigation and environmental flows.

Dam Summary
Facts & History
Glenbawn Dam is situated on the Hunter River about 14 kilometres east of Scone in the NSW Hunter Valley. The dam is about 270 kilometres north-west of Sydney.
Glenbawn Dam has a capacity of 750,000 megalitres, one and a half times that of Sydney Harbour. It has additional potential capacity of 120,000 megalitres for flood mitigation.
Glenbawn Dam is named after a property on which it is built.
Why the dam was built
The dam was built in the 1950s to secure water for agriculture, industry and the surrounding townships, and to mitigate flooding.
Vineyards and pastures for dairy farming are the main agricultural industries supported by irrigation. The dam also provides water for nearby power stations and the towns of Scone and Muswellbrook.
Glenbawn Dam operates in conjunction with Glennies Creek Dam to supply water requirements along 40 kilometres of the Hunter River from Glenbawn to the tidal reaches near Maitland.
A six megawatt hydroelectric power station uses irrigation, flood mitigation and environmental flows.
How the dam was built
Glenbawn Dam is a rock-fill embankment with a clay core. An ungated concrete chute spillway is located about one kilometre south of the dam wall.
The original embankment was 78 metres high, providing a storage capacity of 300,000 megalitres. Construction began in 1948 and finished in 1958. The dam was enlarged in 1987.
Later improvements
Glenbawn Dam was enlarged in 1987, raising the wall to 100 metres high and increasing storage capacity to 750,000 megalitres with additional potential capacity of 120,000 megalitres for flood mitigation.

- Notification - You are advised to move to higher ground and if necessary evacuate.
Red alert
- Trigger - Storage level has reached crest level.
- Notification - Residents are advised to evacuate to their designated flood assembly points.
Flood notifications
Flood notifications indicate the dam is releasing controlled or uncontrolled flows, likely to cause downstream flooding.
Flood operations
- Trigger - Flow increases of 12,000, 30,000 and 60,000 megalitres per day
- Notification - Flows of XX,000 megalitres per day are being passed.
Flood of record
- Trigger - Spillway flows of over 98,000 megalitres per day, last reached in 1995.
- Notification - Flows of over 98,000 megalitres per day are being passed, levels last reached in 1995.
High regulated release notifications
High regulated releases are when our operations may impact landholders immediately downstream or we are releasing higher than normal flows.
Normal operations
- Range - 0 to 1,000 megalitres per day.
- Notification - No notifications in this range.
Increased flows
- Trigger - When flow increases above 1000 megalitres per day, and when they raise to 4,500 megalitres per day for the first time.
- Notification - Releases are planned to increase from XX,000 megalitres per day (ML/day) to YY,000 ML/day at 00:00 on DD/MM/YY.
