The Blackwood, at 300km, is one of the longest rivers in WA’s South-West. Due to inland explorers not realising they were on its headwaters, the upper Blackwood is now known as the Arthur River and the Blackwood name commences at the junction of the Arthur with the Balgarup River near Wild Horse Swamp SW of Moodiarup. It flows generally SW past  the townships of Boyup Brook, Bridgetown and Nannup before entering the sea from Hardy Inlet at Augusta. Besides the Arthur and Balgarup rivers, its tributaries include the Tweed, Hillman, Buchanan, Beaufort and Carrolup rivers. That’s a heck of a catchment.
