In 2005, the $52.5 million Eildon Dam Improvement Project was completed.
The project included strengthening the spillway and reconstructing the upper 10 metres of the embankment, which was then raised a further 5.5 metres to ensure the safety of the dam in extreme floods.
The project was delivered more than $4.5 million under budget and more than two months ahead of schedule.
It received a High Commendation at the 2005 Victorian Engineering Excellence Awards.
