The Koau and Matau Rivers, also called the Koau and Matau Branches, are the two distributaries of New Zealand's Clutha River. The two distributaries split immediately to the southeast of the town of Balclutha, at which point the more northerly branch becomes the Matau and the more southerly becomes the Koau. The two branches both flow generally southeast to reach the Pacific Ocean, surrounding the island of Inch Clutha. A small silty channel connects the two rivers close to their mouths, creating a smaller unnamed island to the south of Inch Clutha.
