Information about managing the storage level at Cairn Curran Reservoir.

Cairn Curran Embankment Closure

GMW is required to manage the safety of the public when they visit the Cairn Curran embankment area, and the ongoing safe operation and maintenance of the storage assets including the embankment, spillway and tower, while also continuing to provide a duty of care to GMW staff while they are at work. To ensure this is achieved, GMW has implemented a public exclusion zone on the embankment immediately adjacent to the spillway at Cairn Curran Reservoir and a permanent fence has been installed.

The existing sealed road linking Cairn Curran Road to the Spillway Reserve will remain open for vehicles and pedestrians at designated times, to allow public access to the monument and spillway reserve.

Public access is being trialled from 6am to 8.30am and 4.30pm to 8pm Monday to Friday and from 9am to 8pm on Saturday and Sunday, in daylight hours. Please note this area may be closed during maintenance.

GMW acknowledges that this is a significant change for local residents and visitors and is committed to working with them to develop a suitable outcome that not only meets GMW’s safety and operational requirements but also continues to delivers a functional recreational space for visitors.

About Cairn Curran Reservoir

Cairn Curran
Cairn Curran


Cairn Curran Reservoir is located on the Loddon River, about 10 km west of Maldon.


Cairn Curran Reservoir was constructed between 1947 and 1956. The storage has a primary spillway, and a secondary spillway situated 2 km south‑west of the main structure that will spill before the embankment is overtopped.


Cairn Curran Reservoir was constructed to supply water for irrigation and domestic and stock use to customers along the Loddon River.

Supplements to the Goulburn supply system are available when resources are abundant.

All visitors are asked to be aware of the dangers associated with low water levels and exercise caution.

All recreation areas and toilet facilities are accessible to the public, except the Spillway recreation area, which has no water.  As the season progresses, it may become increasingly difficult to provide access to recreation areas and toilet facilities if we are unable to supply water to them.
