The Old River is a perennial river of the Port Phillip catchment, located in the Western District region of the Australian state of Victoria.
A perennial stream or perennial river is a stream or river (channel) that has continuous flow in parts of its stream bed all year round during years of normal rainfall. "Perennial" streams are contrasted with "intermittent" streams which normally cease flowing for weeks or months each year, and with "ephemeral" channels that flow only for hours or days following rainfall. During unusually dry years, a normally perennial stream may cease flowing, becoming intermittent for days, weeks, or months depending on severity of the drought. The boundaries between perennial, intermittent, and ephemeral channels are not defined, and subject to a variety of identification methods adopted by local governments, academics, and others with a need to classify stream-flow permanence.
Port Phillip , is a port in southern Victoria, Australia. It is nearly surrounded by the city of Melbourne and its suburbs. Geographically, the port covers 1,930 square kilometres and the shore stretches roughly 264 km (164 mi). Although it is extremely shallow for its size, most of the port is navigable. The deepest portion is only 24 metres (79 ft), and half the region is shallower than 8 m (26 ft). The volume of the water in the port is around 25 cubic kilometres (6.0 cu mi).
The Western District comprises western regions of the Australian state of Victoria. It is said to be an ill–defined district, sometimes incorrectly referred to as an economic region,. The district is located within parts of the Barwon South West and the Grampians regions; extending from the south-west corner of the state to Ballarat in the east and as far north as Ararat. The district is bounded by the Wimmera district in the north, by the Goldfields district in the east, by Bass Strait and the Southern Ocean in the south, and by the South Australian border in the west. The district is well known for the production of wool. The most populated city in the Western District is the Ballarat region, with 96,940 inhabitants.
