An upgrade of Painkalac Reservoir is nearing completion.
Although wet weather has hampered progress, construction is now entering the final phase and work is expected to be completed by mid-May.
The reservoir, which supplies the townships of Aireys Inlet and Fairhaven, is being brought into line with recently updated Australian dam safety guidelines.
The project involves improvements to the 8.6-metre high embankment and concrete spillway.
The 125-metre embankment is being raised two metres and an additional one-metre concrete parapet wall constructed.
Work on the spillway, which was widened four metres and the height of its walls increased by 3.5 metres, has been completed. Raising the embankment is expected to be finished in the next three weeks.
The parapet walls will then be put in place and monitoring equipment installed. A new access road will also be constructed.
Painkalac Reservoir was constructed in 1978.
The project is being delivered by the Barwon Water Alliance.
