Tributaries

The Torrens is fed by numerous seasonal creeks, which are dry for most of the year in their lower reaches, but prone to occasional flooding during the winter and spring. There are five main creeks that join it from the southern side as it crosses the Adelaide Plains east of Adelaide, and at least five more in its path through the Adelaide Hills. The plains tributaries, known as First to Fifth Creeks, lie to the east of the city, with First being the most southerly and the rest numbered consecutively northward. They were once named Greenhill, Hallett, Todd, Anstey and Ormsby rivulets respectively, and had

It remains the only reservoir damming the river rather than being fed from weirs. The "River Torrens Committee" was formed in 1964 to advise the minister of works on preserving and enhancing the river's natural beauty, and developing it for recreational uses. The "River Torrens Acquisition Act 1970–72" was passed, authorising the purchase of land, in some cases 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.

was used to build a wooden dam near the site of the current weir. The dam 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 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 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.

Water use

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 a dysentery outbreak killed five children in one day, Governor Gawler forbid bathing, clothes washing and the disposal of animal carcases in the Torrens within 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 built a facility with steam powered pumps and water storage in 1852, from which the carters then filled.Altmann et al. 1999, p.6 The "Waterworks Act" of 1856 was passed to enable damming of the upstream Torrens for water supply purposes.Altmann et al. 1999, p.3 The resulting "Water Commission" arranged the following year for foundations to be laid for a water supply weir from Adelaide near Campbelltown. Unsuitable geology and shoddy work by contractors Frost & Watson led to it being washed away in July 1858 and the site abandoned. Engineer

was replaced by John England. Government then created a Waterworks Department, which started construction of a weir from the city and reservoir at Thorndon Park in 1859. The weir was completed on 4 June 1860 and the reservoir began supplying piped water in December. Engineer England was found by a Select Committee to have overpaid 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, the

They were supplied with reticulated water from the Torrens and progressively upgraded with the last change a 1940 remodelling including an Olympic-size swimming pool and diving tower. The baths were demolished in 1970 to make way for the Adelaide Festival Centre. The Millbrook Reservoir was constructed high in the Adelaide Hills from 1913 to 1918 submerging the town of Millbrook.

Bridges

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 west of the current City bridge, but destroyed by floods in September 1844. In 1849 £6,000 was allocated to bridge the Torrens. 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.
