At its 1836 discovery an inland bend was chosen as the site of Adelaide and North Adelaide. The river is named after Colonel Robert Torrens, a significant figure in the city's founding. In Adelaide, is also known by its native Kaurna name Karra wirra-parri. The river and its tributaries are highly variable in flow, and together drain an area of 508 km2. They range from sometimes raging torrents, damaging bridges and flooding city areas, to trickles or completely dry in summer. Winter and spring flooding has prompted the construction of flood reduction works. A constructed sea outlet, landscaped linear parks and three holding reservoirs contain peak flow. The river's flora and fauna have been both deliberately and accidentally impacted since settlement. Native forests have been cleared, gravel removed for construction and many foreign species introduced. With construction of the linear parks, many species native to the river have been replanted and introduced species controlled as weeds. Since European settlement the river has been a frequently touted tourist attraction. The river formerly acted as the city’s primary water source and main sewer, leading to outbreaks of typhus and cholera. |
