Blackwood River
The Blackwood River is a major river and catchment in the South West region of Western Australia.
The river begins at the junction of Arthur River and Balgarup River near Quelarup. It travels in a southwesterly direction through Bridgetown then through Nannup until it discharges into the Southern Ocean at Hardy Inlet near the town of Augusta.
Hardy Inlet has a number of islands – namely Molloy Island and Thomas Island. The mouth of the river has attracted interest in its various points of opening and closing over the last 100 years, Duke Head at the west side being a benchmark location for the shifting mouth.
The river has 42 tributaries including Dinninup Brook, Balingup Brook, St John Brook, Boyup Brook, Tweed River, Ti Tree Gully, Christmas Creek and Tanjannerup Creek.
The river has a total catchment area of 28,100 square kilometres (10,849 sq mi) stretching from Kukerin in the east to Hardy Inlet in the west, and from Darkan in the north to Augusta in the south.
Several major towns are found within the catchment including Katanning, Narrogin, Bridgetown, Boyup Brook and Nannup.
The upper or larger catchment area of the river is in agricultural areas, while the middle catchment area passes through forest areas, and the lower portion of the river passes into mixed forest, agricultural, and residential lands. The middle catchment passes through what is known as the Blackwood Plateau between the Whicher Scarp and the Scott Coastal Plain.
The river emerges into Flinders Bay at Augusta.
