About Cairn Curran Reservoir

There is current a blue-green algae warning for Cairn Curran Reservoir. Click here for further information.

History 

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.

Operations

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.

Location

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

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.

Local anglers advise that using yabbies as bait on a running sinker can increase your chances of catching Redfin.

The water in Cairn Curran Reservoir is owned by GMW customers, who produce food and fibre, supply towns and businesses downstream of the storage, and protect and improve environmental waterway health. 

Visitors need to be conscious of potential hazards and consider their own safety and the safety of other users at all times. Water levels (high or low) can prompt increased safety measures, and changes to access for recreational areas and boating. Safety information and alerts will be signposted at public areas and boat ramps.

 Boating rules at Cairn Curran may change depending on water level.

  • Level 1 (normal water levels) is above 28% capacity and normal boat zoning rules apply
  • Level 2 (low water levels) is between 28% capacity and 13% capacity, and means those travelling above five knots are restricted to the waters at Tower Bay and south of a line of buoys running parallel to the main embankment
  • Level 3 (very low water levels) is below 13% capacity, and this means the reservoir is closed to vessels operating at a speed above five knots.

Refer to the Guide to Vessel Operating and Zoning Rules for Victorian watersand current water level information.

At times, the level of blue-green algae in storages can exceed safe limits. When this happens you should avoid direct contact with the water as the algae can cause;

  • skin rashes
  • itchiness
  • sore eyes, ears and nose
  • nausea.

If unsafe levels occur, warning signs will be positioned at major recreational areas.

Online Blue-green algae warnings are available or by calling the 24 hour GMW blue-green algae hotline on  (03) 5826 3785.

Camping at Cairn Curran Reservoir is only allowed in commercial caravan and holiday parks located around the water storage (see map).
