Spillway Road Bridge Maintenance Works 

Update 15 April 2021 - Rodborough Road over the Tullaroop Spillway Bridge will close in both directions from Thursday 22 April to Saturday 24 April 2021, as part of the maintenance works currently underway on the bridge. An alternate route will be signposted during the closure period and the road will reopen on Sunday 24 April 2021.

From early February to late April 2021, maintenance works will be undertaken on the Spillway Road bridge to replace the support bearings and re-paint the bridge.

The works are expected to take 12 weeks depending on weather conditions. During this time there will be reduced speed limits over the spillway bridge and there will be periods of up to two days when the bridge will be closed to all road users, including emergency services. During these closures, an alternate route will be signposted.

For visitors to the storage, there will be no change to public access to the embankment if accessed from the West. Access from the East will not be possible due to the bridge works.

Works will be undertaken during daylight hours from Monday through to Saturday with night works only in the event urgent work is required to secure the site.

As we expect some increase in traffic on the roads near the reservoir, we ask drivers to take extra care.

We anticipate that there may be some additional noise and dust. All works will be conducted within Environment Protection Authority (EPA) guidelines. The worksite will include scaffolding with an encapsulated air-conditioning system to ensure the old paint is contained and removed in a safe manner with no risk to the environment and workers.

GMW staff and contractors will also be adhering to current government COVIDSafe guidelines while undertaking the works if needed.

If you have any questions about the works, please email GMW Project Manager Don Carroll at Don.Carroll@gmwater.com.au or call 1800 013 357.

About Tullaroop Reservoir


Tullaroop Reservoir dams the Tullaroop Creek, a tributary of the Loddon River. The storage embankment is situated about 7 km south-east of Carisbrook.

History Tullaroop Reservoir

Tullaroop Reservoir was built between 1958 and 1959. The construction involved substantial excavation, including the removal of 300,000 cubic yards of material from the bed of Tullaroop Creek.


Tullaroop Reservoir stores water for supplies to irrigated properties along Tullaroop Creek and the Loddon River.

Supplementation of the western sector of the Goulburn water supply system using Loddon River resources such as that held in Tullaroop Reservoir occurs when water resources are abundant.

The reservoir also provides water for Maryborough.
