Compared with most of the other dams in the Hills
Scheme supplying high quality drinking water to the
people of Perth, North Dandalup Dam is a relatively
recent construction. Opened by former State Premier
Richard Court in October 1994, it was the final project in
a dam building program that included the new Victoria
and Conjurunup Dams.
The $50 million project to dam the North Dandalup River
significantly boosted storage capacity to meet the needs
of the City’s growing population.
With a capacity of 75 million kilolitres, it is able to supply
about 10 per cent of Perth’s annual water consumption.
As well as the main dam, two earthfill saddle dams, the
larger 22 metres and the smaller nine metres high, were
built on low lying ridges slightly to the northwest.
The original small pipehead dam, which operated from
1971 until replaced by the larger dam, still plays a useful
role as a recreation lake for visitors. It can be seen just due
south of the main dam wall
