At the very end of Harris River Road.
North of Collie, Harris Dam is a peaceful, relaxing location, with native gardens, grassed areas for hitting the football or throwing a frisbee, free gas barbecues, picnic tables and toilet facilities.
A walk along the Bibbulmun Track, or from the picnic area to the top of the earth wall embankment, is a great way to work up an appetite or to walk off lunch.
Harris Dam is a water supply, so swimming, fishing, camping are not permitted. Dogs on a leash are welcome except in the water catchment area.
