The Curdies River is a perennial river of the Corangamite catchment, located in the Otways region of the Australian state of Victoria.
Curdies River rises below the settlement of Tandarook in southwest Victoria, east of the settlement of and flows generally south by west, joined by six minor tributaries, before reaching its river mouth in the Port Campbell National Park and emptying into the Great Australian Bight at Curdies Inlet, at the settlement of . From its highest point, the Curdies River descends over its 66km (41miles) course.[2]
Curdies Inlet, when full, covers an area of around 280 hectares and is located near the mouth of the Curdies River. Reasonable fishing and birdwatching can be enjoyed in the inlet.
The mouth is periodically blocked by sand. Sometimes, in order to avoid flooding around Peterborough, it has to be opened by excavation.[3]
The river was named after the first doctor in Cobden, Daniel Curdie.
In April 2022, a blue-green algae outbreak started in the river. Some parts of the river turned green and emitted a strong putrid smell. Dead fish and cattle were found dead and floating in the river.[4]
EPA Victoria investigated 25 dairy farms situated within the catchment of the River. Two of the 25 inspected farms were not taking care of their effluent properly.[5]
The algae outbreak was due to the fact that the majority of the nutrients remained and built up at the bottom of the river after entering it between July and October and being stimulated by the warmth and sunlight of the summer.[6]
