78-671: The River Torrens / ˈ t ɒr ən z / ( 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
156-582: A gorge after Cudlee Creek . It flows through the gorge to Athelstone , passing over the Eden Fault Zone of the Adelaide Hills face and associated escarpment. After the scarp it flows over sedimentary rocks of varying resistance to erosion , which has led to interspersed narrows and broad basins. From the base of the Adelaide Hills to the Adelaide central business district it runs in a shallow valley with
234-529: A 1-in-200-year flood. When the O-Bahn Busway was opened, the bridges were designed to cope with this scale of flood, although the two bridges in St Peters would likely be awash. The 470 ML (17 million cu ft) Torrens Lake was created in 1881 with the construction of a weir, landscaping of Elder Park and modification of the river's bank and surrounds into an English formal park. The lake forms

468-406: A centrepiece of many Adelaide events and postcard scenes. Elder Park with its iron rotunda was opened on 28 November 1882. The Rotunda is a largely Glasgow built 9-metre-high (30 ft) iron bandstand which was funded by Sir Thomas Elder , the park being named after him. In 1867, prison labour from nearby Adelaide Gaol was used to build a wooden dam near the site of the current weir. The dam
546-500: A choir in Popeye 4 . Prime Minister Malcolm Fraser officially launched three new fibreglass models named Popeyes I , II and III in 1982 as the wooden boats' replacements. In the early days of Adelaide, the Torrens was used for bathing, stock watering, rubbish disposal, water supply and as a de facto sewer and drainage sump. This led to a range of health issues until finally, in 1839, when
624-637: A church some distance away. The town prospered by the 1850s, and the area was producing enough grain to justify the construction of the Blumberg Flour Mill (now the site of the motor museum). In 1865, during the local gold rush, the Blumberg Inn was built. Birdwood sits on a crossroads between the Adelaide-Mannum Road , the road leading north towards Williamstown and the Barossa Valley , and
702-507: A dysentery outbreak killed five children in one day, Governor Gawler forbade bathing, clothes washing and the disposal of animal carcases in the Torrens within 1.6 kilometres (1 mi) of town. The quality of the river's water was not helped by water supply methods. Carters used to drive water carts into the Torrens to refill. To prevent this the State Government in 1852 built a facility with steam powered pumps and water storage, from which
780-540: A terraced floor, then down the slope of its own alluvial fan . The structure of this fan shows that the river formerly entered Gulf St Vincent via the Port River . Over time the Torrens deposited sediment , choking its own outflow; becoming locked behind coastal sand dunes and forming the swampy areas of the Cowandilla Plains and The Reedbeds . The Torrens is fed by numerous seasonal creeks, which are dry for most of
858-408: A vast but shallow freshwater wetlands . These wetlands, known as The Reedbeds after the dominant vegetation, occupied a large area of the western Adelaide Plains and were also fed by other waterways. The river only flowed to the sea through the Port River , Barker Inlet , and Patawalonga River following heavy rain. The river's catchment area of approximately 500 km (193 sq mi)

#1732845396838936-644: A village on the Oder River in the settlers' area of origin. The German town name was anglicised to "Birdwood" during World War I , along with many others in the region in 1917. The new name honoured Sir William Birdwood , the Australian Imperial Force general who led the ANZACs at Gallipoli . Around the same time, the government closed the German-language school . The first Europeans to explore
1014-436: A weir on the river at Gumeracha , its elevation allows gravity supply of water to Adelaide's eastern suburbs. Due to the river's path through the centre of Adelaide, transport necessitated the construction of many bridges. Prior to the bridges all crossings had been via fords which proved a dangerous practice in winter and spring. The first bridge was one of timber built in 1839 approximately 500 metres (1,600 ft) west of
1092-457: A year with 785.6 millimetres (30.93 in) of rain compared to the Adelaide average of 530 millimetres (21 in). The river flooded market gardens and farms throughout its hills course causing extensive damage. Norwood was inundated to The Parade , Adelaide to Pirie and Rundle Streets, and many areas west of the city were left in a shallow lake. The river ran 9 feet (2.7 m) deep over
1170-560: Is a town in the Adelaide Hills area of South Australia , around 44 km (27 mi) from Adelaide city centre . It is located in the local government areas of the Adelaide Hills Council and the Mid Murray Council . Birdwood was originally named Blumberg. by Prussian settlers originating from the area around Zullichau . The original name's origins are uncertain, but it is likely that it derives from Groß Blumberg ,
1248-724: Is just beyond the town limits; the United Church in the centre of town, which united long before the Uniting Church formed, and the Seventh-day Adventist Church further along Shannon Street. Birdwood is also home to the National Motor Museum (in what used to be the Old Mill), and is the endpoint of the annual Bay to Birdwood run [1] , in which vintage motor vehicles are driven by their owners from Glenelg past
1326-437: Is now covered by the city of Adelaide , the capital of South Australia . The central area is considered the breadbasket of South Australia with many market gardens and wineries, particularly around the towns of Virginia and Angle Vale . The northern area is predominantly used for growing cereal grains such as wheat , barley , and canola , and farming sheep . Usage of the term Adelaide Plains frequently refers to
1404-498: Is now the official name of Fourth Creek. This name has been adapted to Morialta, which is now the name of an electoral district , school and the park through which the creek flows. Fifth Creek arises within the Morialta Conservation Park, runs alongside Montacute Road for some way and discharges into the Torrens at Athelstone . The largest catchment of the Torrens is Sixth Creek in the Adelaide Hills, which joins
1482-548: Is the largest of any waterway within the Adelaide region. The upper reaches are used to create a potable water supply for metropolitan Adelaide with the river supplying three of Adelaide's eight reservoirs. The upper catchment has an average annual rainfall of between 575 millimetres (22.6 in) at its eastern end to 1,025 millimetres (40.4 in) near Uraidla . The Torrens has a very variable flow leaving early settlers to use trial and error in determining bridge heights, with many bridges consequently being washed away. Due to

#17328453968381716-590: The Adelaide Zoo . The first boat was launched on the Torrens Lake by Gordon Watts in 1935. It was a 25-foot (7.6 m) boat, built on the banks of the Torrens to hold up to 20 passengers and named Popeye 1 . Watts purchased a former Glenelg cruise boat in 1948 and placed it in service as Popeye 2 . Over the next two years three new jarrah hulled boats were built at Port Adelaide ; carrying 40 passengers each they were numbered Popeye 3 through Popeye 5 . Trips on
1794-485: The Adelaide-Mannum Road , and the sites of these are marked with red and black posts. Birdwood once had a train station on the Mount Pleasant railway line at 44.13 miles (71 km) from Adelaide . The line came via Balhannah and was not a very direct route. The line was closed during one of the rail reformations as it was not a very profitable line, probably due to the more direct Adelaide–Mannum Road . The track

The river then continues the remaining eight kilometres to the sea at Henley Beach South, emptying into Gulf St Vincent via a constructed outlet. Hope Valley , Millbrook and Kangaroo Creek Reservoirs, which provide water storage for Adelaide, capture
2028-703: The Paleozoic era then further dislocated during the Cretaceous and earliest Tertiary . There is a 400-metre (1,300 ft) subsidence along the Para Fault which also affects the rivers flow. This subsidence was formed in the last two million years, after the Pliocene era. From its origin to Birdwood the river follows rolling, relatively level country before entering a hilly section that continues to Gumeracha . The river then follows sedimentary rock strata before entering
2106-579: The "Parliamentary Standing Committee on Public Works" recommended that an outlet for the river be created to accommodate flows of up to 370 m/s (13,000 cu ft/s), covering a 1-in-60-year flood. The work was partly financed by a Commonwealth Government grant with the State Government arranging for the balance. The State Government, western and eastern local councils and the Municipal Tramways Trust shared interest costs. The scheme
2184-424: The 1889 flood, the weir was overwhelmed, its gates jammed, and in trying to free them the weir's designer John Langdon was crippled. The weir was rebuilt from 1928 to 1929 with its footbridge relocated and the centre section replaced. The gates can now be fully raised and the river allowed to flow unimpeded. The " Popeye " boats are privately owned recreational ferries that operate on the lake between Elder Park and
2262-565: The 19th century, native forests were 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 have been controlled as weeds. The river and its tributaries are highly variable in flow, and together drain an area of 508 square kilometres (196 sq mi). They range from sometimes raging torrents, damaging bridges and flooding city areas, to trickles and completely dry in summer. Winter and spring flooding has prompted
2340-414: The 2,840 ML (620 million imp gal; 750 million US gal) Hope Valley Reservoir in the foothills of the Adelaide Hills was completed as a storage reservoir, supplied via an aqueduct and tunnel. Public baths were built in 1861 just north of the current Parliament House . They were supplied with reticulated water from the Torrens and progressively upgraded with the last change
2418-538: The Kangaroo Creek dam's level was raised, its spillway modified, the Breakout Creek channel capacity increased and some bridges reinforced. A development plan was approved in 1981 to purchase land along the length of the river, create a flood mitigating linear park and also to modify the Kangaroo Creek dam further. The sea outlet was enlarged to a capacity of 410 m/s (14,000 cu ft/s) which now covered

Rowers use the lake for training all year round, and many clubs such as the Adelaide University Boat Club , the Adelaide Rowing Club , and the boat houses of the secondary schools which participate in the annual Head of the River are located upon its banks. Several rowing regattas are held on
2574-501: The Popeyes from Elder Park to the zoo became a treasured family outing and the boats hosted weddings and other events. In March 1962 Keith Altman, owner of riverside eatery "Jolley's Boathouse", took over the Popeyes and introduced recreational paddle boats to the river. The Popeyes had a brush with royalty in March 1977 with Popeye 5 ferrying Queen Elizabeth II and Prince Philip followed by

Stonyfell Creek , arising on the eastern boundary of Stonyfell , flows through Kensington Gardens , including an open stretch in the Reserve before again being piped underground under West Terrace, passing under Kensington Park and Beulah Park . It joins Second Creek near the junction of Magill and Portrush Roads . First and Second Creeks come within about 46 metres (50 yd) of each other in Marryatville, with formerly only flat land between them. Third Creek arises near Norton Summit and flows through
2886-471: The board of Colonisation Commissioners for South Australia from 1834 to 1841 (when he was sacked). From March 1837 settlers camped in tents and makeshift huts along the west end of the River Torrens and freely used the river's resources. A Native Location was created on the north banks of the Torrens and indigenous labour was often used by the settlers for tasks such as hewing wood or delivering water. During
2964-481: The carters then filled their casks. The "Waterworks Act" of 1856 was passed to enable damming of the upstream Torrens for water supply purposes. The resulting "Water Commission" arranged the following year for foundations to be laid for a water supply weir 11 kilometres (7 mi) from Adelaide near Campbelltown . Unsuitable geology and shoddy work by contractors Frost & Watson led to it being washed away in July 1858 and

The museum was started by Jack Kaines and Len Vigar in 1964, and was purchased by the South Australian Government in 1976, holding a large and historically important collection of cars, motorcycles and commercial vehicles. Next door to the Museum is the Birdwood Motel (2015), Just north of Birdwood is the Cromer Conservation Park , proclaimed in 1976, with an open-forest formation of long-leafed box with Pink Gum and an open woodland formation of Red Gum , which forms an important habitat for honeyeaters . Mining for yellow ochre occurred in
3120-612: The construction of flood reduction works. A constructed sea outlet, landscaped linear parks and three holding reservoirs contain peak flow. The River Torrens runs largely westward from the Adelaide Hills, through the centre of Adelaide to the Gulf St Vincent. It originates close to the eastern fault scarp of the Mount Lofty Ranges , near Mount Pleasant , approximately 480 metres (1,575 ft) above sea level . It runs predominantly along faulted north-south ground structures, which were formed over 250 million years ago during
3198-470: The contractors and forced to resign. The water was captured at the weir, piped for storage to the Thorndon Park Reservoir then to a water tower at Kent Town. Water from Kent Town storage was distributed via a manually controlled water system, unmetered for its first six years. Within six years 20,000 citizens in Adelaide and Port Adelaide were connected to reticulated water from the Torrens. By 1872,

Within four years three wooden bridges had been built and subsequently destroyed in floods. The bridges listed below are from up-river to down-river. The river was formerly a food source with yabbies , mussels and small fish, however the reduction in water quality, changing of
3354-576: The department of works favoured a cutting through sand dunes near Henley Beach allowing the river an outlet, mitigating floods and preventing silting of the Port River. He also advocated the construction of a reservoir where the Kangaroo Creek Reservoir is now, to both mitigate floods and provide summer irrigation water for market gardens. Unfortunately the bill lapsed with no action as the government and local councils were unwilling to fund

In 1839-40 the South Australian Company claimed several Special Surveys in the district which were later subdivided to allow for closer settlement. Migrants who had temporarily settled at Lobethal began looking for land of their own in 1848. Pastor Fritzsch recommended this spot beside the Torrens, where he camped on the way to Bethany . Birdwood grew with homes on land leased from George Fife Angas and

Since European settlement the river has been a frequently touted tourist attraction . The river's long linear parks and a constructed lake in the lower stretch are iconic of the city. The river's flora and fauna have been both deliberately and accidentally impacted since settlement . In
3588-419: The flooding elsewhere. Two early floods were, 18 September 1841 which resulted in two people drowning while trying to cross the river at Klemzig , and 22 September 1844, the largest recorded since settlement began, when "Shands' Brewery" was washed away after the river undermined its foundations . The 1899 flood was particularly widespread with extensive flooding of both the river and its tributaries , after

Traditionally entirely occupied by the Kaurna (indigenous) people, the Adelaide Plains are crossed by a number of rivers and creeks, but several dry up during summer. The rivers (from south to north) include: the Onkaparinga/Ngangki , Sturt/Warri Torrens/Karra Wirra , Little Para , Gawler , Light/Yarralinka and Wakefield/Undalya . The plains are generally fertile with annual rainfall of about 460 millimetres (18 in) per year. The plain can be roughly divided into three parts. The southern area

Still present are many of the original vegetation species like: Sheoak ( Casuarina stricta ), native cherry ( Exocarpos cupressiformis ), native pine ( Callitris preissii ) and Australia's floral emblem the golden wattle ( Acacia pycnantha ) From its source the river flows westwards through Birdwood and Gumeracha . It then continues down through Torrens Gorge entering suburban Adelaide at Athelstone with some of its path paralleled by
3822-428: The lake are icons of the area and frequently featured in postcard photographs of the city. Due to now-limited natural river flow and stormwater born organic material, the lower river, (particularly the lake), is often polluted with algal blooms and significant levels of E. coli bacteria in spring and summer. Numerous taskforces have been formed to improve the river's water quality , including one created in 2006 by

In places the steep banks of the river are an ideal habitat for long-necked tortoises . The river, and its tributaries, had a population of water rats (Hydromys chrysogaster) and Australian swamp rats ( Rattus lutreolus ). Water rats remain in reduced numbers, but the introduced black rat ( Rattus rattus ) and brown rat ( Rattus norvegicus ) have largely supplanted

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
4446-475: The river has been dually known by the indigenous Kaurna people's name of Karra wirra-parri (meaning river of the Red Gum forest), referring to the dense eucalyptus forest that lined its banks prior to clearing by early settlers. This name, alternatively Karra-weera , only referred to the lake section of the river, between Adelaide and North Adelaide. It was known as Karrundo-ingga at Hindmarsh , Witoingga near
4524-442: The river's alluvial fan. As development of Adelaide progressed the amount of rainfall required for flooding decreased and consequent damage increased. Increased stormwater runoff, modification of the river's banks and other changes all served to exacerbate the problem. Work done by various groups to minimise flooding was often counter productive with the creation of levees , moving and widening channels and other works simply shifting

The "River Torrens Acquisition Act 1970–72" was passed, authorising the purchase of land, in some cases 60 metres (200 ft) back from the top of the river's banks. By 1980, further development along the riverbanks and removal of levées had reduced the outlet's capacity to a 1-in-35-year flood. A study showed that a 1-in-200-year flood would inundate 13,000 properties; so

5772-456: Was enacted in 1935 with the construction of the Breakout Creek (also sometimes Breakout Channel ) to take the Torrens westwards to the sea, completed in 1937. The scheme involved diversion of the river at Lockleys (near Adelaide Airport ), with the original channel blocked and a new channel created to the sea. The reedbeds and swamps were subsequently drained and some of their area is now
5850-614: Was named "The Yatala" by the party but later renamed by Surveyor General Colonel William Light after Robert Torrens , chairman of the South Australian Colonisation Commission . On 29 December 1836 Light announced the location of the new city of Adelaide, 6 miles (9.7 km) inland on the river's banks. The first Europeans to explore the Torrens Gorge to the headwaters and sources of the river were Dr George Imlay and John Hill in January 1838. In recent years
5928-414: Was poorly constructed and almost immediately the Torrens washed it away. Construction of a permanent concrete weir was begun in November 1880 and completed, at a cost of £7,000, in 1881. The sluice gates were closed to begin filling the 12-hectare (30-acre) Torrens Lake on 1 July 1881. At the lake's official opening on 21 July 1881 an estimated 40,000, almost the entire population of Adelaide, attended. During
6006-478: Was removed, the banks were eroded and the riverbed gradually levelled as waterholes filled. By 1878 the river was noted to be a malodorous, black sewer rather than the sylvan stream of the 1830s. ...anything in the guise of a river more ugly than the Torrens would be impossible to either see or describe... Much of the river's catchment area consists of cleared farmland with run-off captured in private dams to sustain farming over Adelaide's dry summer. Combined with
6084-544: 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. At its 1836 exploration by William Light , an inland bend was chosen as the site of the Adelaide city centre and North Adelaide . The river was first named the Yatala by the initial exploration party, but later renamed to honour Robert Torrens senior, chairman of
