West Beach, South Australia in the context of "River Torrens"

The River Torrens /ˈtɒrənz/ (Karrawirra Parri / Karrawirraparri) is the most significant river of the Adelaide Plains. It was one of the main reasons for the siting of the city of Adelaide, capital of South Australia. It flows 85 kilometres (53 mi) from its source in the Adelaide Hills near Mount Pleasant, across the Adelaide Plains, past the city centre and empties into Gulf St Vincent between Henley Beach South and West Beach. The upper stretches of the river and the reservoirs in its watershed supply a significant part of the city's water supply.

The river is also known by the native Kaurna name for the river—Karrawirra Parri or Karrawirraparri (karra meaning redgum, wirra meaning forest and parri meaning river), having been officially dual-named in 2001. Another Kaurna name for the river was Tarndaparri (Kangaroo river). The river was thought to be a reflection of the Milky Way ("wodliparri"), and was the heartland of the Kaurna people, who lived along its length and around the tributary creeks.
