South Dandalup Dam

The largest of all dams supplying Perth, South Dandalup Dam is a popular destination all year for its tall trees, rich birdlife, and close proximity to the historic timber town of Dwellingup.

 

Please note: There are some instances when our dam recreation areas will be closed, particularly in summer when there may be a bushfire risk. Before planning a visit to one of our dams, phone us 24 hours on 13 13 75 or check our Facebook page for a post about dam closures.
