The Blackwood River is a major river and catchment in the South West of Western Australia.
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 river emerges into Flinders Bay at Augusta.
It was first discovered by a Europeen in 1827 by Captain (later Admiral Sir) James Stirling and named in honour of Henry Blackwood, under whom Stirling had served as a youth from April 1808 to April 1810.
Historically it was of considerable importance in the early days of the Swan River Colony, and more recently of importance in the ecology of the Augusta-Margaret River region due to conflicts in land use policy.
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.
