The Blackwood River is a major river in south-west of the Australian state of Western Australia.

Geography

It arises in the Darling Range from the confluence of the Arthur River and Balgarup River, flows in a northwesterly direction to Cape Leeuwin where it discharges into the Indian Ocean, after passing through the town of Augusta. The river reaches a length of about 380 kilometers.

At the upper reaches of the river flows through agricultural area, while the middle course runs mostly through forest. In the lower reaches there are both agriculture and forests, but also densely populated areas.

The Hardy Inlet, in the Blackwood River flows, has a number of islands including Iceland and Thomas Molloy Iceland. The estuary in the Southern Ocean at Augusta has repeatedly closed in the past 100 years and re-opened. The Duke Head on its west side can serve as a reference point for these changes.
