The project
This project is being delivered on Dja Dja Wurrung Country.
A project is underway to explore options for strengthening the dam wall of the reservoir, ensuring it can remain safe and open to park visitors for many years to come.
Parks Victoria regularly monitor dams across our parks to ensure they are safe. An independent engineering assessment has found that this 156-year-old reservoir needs works to ensure that it remains safe should a heavy flooding event occur.
The first phase of this multi-year project will explore options for upgrading and making the reservoir safe, so that the community can continue to enjoy this tranquil spot in the Castlemaine Diggings National Heritage Park.
Expedition Pass Reservoir was constructed in 1868 to supply water to Chewton and Castlemaine until 1874, when silting reduced capacity so severely that an alternative supply from the Coliban River was secured. Since then, the reservoir has become a popular place for locals and tourists, with a significant number of people visiting the park and Expedition Pass across the warmer months.
Project funding
The Victorian Government is investing $6.42 million to upgrade Expedition Pass Reservoir.

FAQs
Why is the reservoir being upgraded?
Extensive engineering studies have found that dam needs upgrading to keep the reservoir safe and to ensure its longevity.
How will the reservoir be upgraded?
We’re currently undertaking site assessments to determine the best option for making the reservoir safe by strengthening the dam wall. We’ll continue to update the community as assessments progress and designs for the upgrade are developed. To stay updated on the project, subscribe for updates.
When will the project start and finish?
Undertaking works on public land requires careful planning. This can take time – but it’s essential we deliver projects in the right place and in the right way. This will be a multi-year project. Engineers, cultural heritage advisors, arborists, and flora and fauna specialists will assess the site to understand the best way forward and develop designs for the upgrade. We’ll continue to provide updates as things progress and project timelines are confirmed.
What environmental and cultural heritage management is being undertaken?
Comprehensive planning, environmental and heritage assessments will be undertaken as part of the project.
