Greaves Creek dam history

A concrete arch dam, Greaves Creek Dam was built in 1942 and upgraded in 1993.

It is believed that in 1941 workers placed a time capsule in the centre line of the wall, at the top water level. The capsule contains a list of the workers’ names and a dedication about pride in their workmanship in building a dam that “will remain stable and durable and will impound the rains which fall on the catchment for centuries to come”.

The dam originally supplied communities from Medlow Bath to Mt Victoria with water from the Greaves Creek water filtration plant. Today, the dam supplies water via the Cascade dams to the Cascade water filtration plant, which provides water to the middle and upper Blue Mountains.
