Overhauls
Routine maintenance activities are required to enable the ongoing safety and reliability of our assets. These maintenance activities, which require the generators to be taken out of service, are planned in advance and in consultation with the Australian Energy Market Operator (AEMO). However, there are times when unplanned outages are required.
Outages typically involve one generation turbine coming offline at a time, full outages where all turbines are offline are scheduled on a 4-5 year cycle.
Natural river flows remain unaffected by outages.
Water releases to enable generation will be reduced during outages dependent on the number of turbines that are offline. For example, at Kareeya during a partial outage when one turbine is offline, the power station can generate max 66MW, releasing 66ML down the river.
| Station | Outage commences | Outage ends (inclusive) |
|---|---|---|
| Koombooloomba | 6 June 2023 | 6 October 2023 |
| Barron Gorge | 7 August 2023 | 30 September 2023 |
| Kareeya | 11 September 2023 | 15 September 2023 |

Dam Management
CleanCo has three dams which support energy generation for our assets.
Koombooloomba Dam
| Location | 30km south of Ravenshoe |
| Storage Capacity | 186,750 ML |
| Area | 1600 ha |
| Catchment area | 163km2 |
Located 39km by road south-east of Ravenshoe on the Tully River in north Queensland, Koombooloomba Dam is the storage reservoir for the Koombooloomba and Kareeya hydros.
Koombooloomba Dam is accessible to the public for recreational use however when the capacity is below 25% or above 90%, restrictions apply for vessels powered by engines in excess of 3 kilowatts or 4 horsepower.
CleanCo proactively manages the water levels of the dam through generation activities.
Dam failures are extremely rare, however it’s important that neighbours and people downstream of dams know what to do in the unlikely event of an emergency.
Splityard Creek Dam
| Location | 30km north-west of Ipswich |
| Storage Capacity | 28,700 ML |
| Area | 104 ha |
| Catchment area | 3.8km2 |
Located above the Wivenhoe Pumped Storage Hydro Power Station in the Somerset Region, Splityard Creek Dam is the upper reservoir for hydro generation. This dam is not accessible to the public for recreational water activities.
Water levels in Splityard Creek Dam are not published as water is released and pumped on a regular basis as required to meet energy generation needs. CleanCo proactively manages the water levels of the dam through generation activities.
Dam failure is extremely rare, however it’s important that neighbours and people downstream of dams know what to do in the unlikely event of an emergency.
Swanbank Cooling Water Dam
| Location | 10km south of Ipswich |
| Storage Capacity | 863 ML |
| Area | 27 ha |
| Catchment area | 744 ha |
Swanbank Cooling Water Dam is the main water storage facility for the Swanbank E Power Station, located on Oaky Creek just upstream of Bundamba Creek near Ipswich. The water is used to cool steam exhausted by the power station’s steam turbine during generation.
Water levels in Swanbank Cooling Water Dam are not published and the dam is not accessible to the public for recreational water activities.
Dam failures are extremely rare, however it’s important that neighbours and people downstream of dams know what to do in the unlikely event of an emergency.

Recreational River Use
CleanCo is committed to establishing and maintaining positive relationships with the communities within which we operate, with a focus on supporting local businesses and community initiatives. We are committed to engaging with the paddling community to support the continuation of recreational water activities on the Tully and Barron rivers.
Upcoming overhauls
At times, the Kareeya and Barron Gorge hydros are taken out of service to allow for maintenance activities to take place. While every effort is made to plan these works in advance, there are times when unplanned outages are required.
Staying safe on our waterway
Water levels in Tully Gorge and Barron Gorge can increase and decrease rapidly and without warning.
