Canning Contour Channel

The Canning Contour Channel is a water distribution system spanning about 16 kilometers through the Darling Scarp using concrete channels and metal pipes. It flows by gravity from Canning Dam through Roleystone and Kelmscott, ending in Gosnells.

The system was built between 1935 and 1936 during the Depression, employing local workers to ensure Perth's water supply. This project represented a major effort to develop the region's water resources during an economically difficult period.

The channel shaped how this region developed its relationship with water distribution and land use. Walking along it today reveals how such infrastructure became woven into the local landscape and community needs.

The system uses siphons to cross major roadways and valleys, showing its engineering complexity. Visitors can explore various sections of the channel, though some areas are difficult to access and you should prepare for the terrain.

A section at Araluen collapsed in 1950, revealing how much strain the infrastructure faced from the terrain. This event shows the challenges that early water systems had to overcome in this region.
