Learn moreAbout Contour Channel Walk, Banyowla Regional Park
The Contour Channel walk follows a series of man-made concrete channels and steel and cast-iron pipelines along the contours of the Darling Scarp through Roleystone and Kelmscott. The project was a Depression era public works scheme and constructed, mostly by manual labour, between July 1935 and December 1936 to carry potable water from just below Canning Dam through the hills to a pumping station near Gosnells by following the natural contours of the Canning Valley and scarp - hence it was entirely gravity-fed. The channel supplied drinking water to the metropolitan area of Perth from 1940 to 1975.
The walk trail passes through forests of Marri and Flooded Gums and offers great views over Perth City and the Swan Coastal Plain. The area nearer to Canning Mills Road has a rich and diverse range of wildflowers from July to November.
Kangaroos and Black cockatoos can often be seen throughout the woodlands here.
