In 1697 Willem De Vlamingh (there are alternate spellings of this name) named the Swan River after the large flocks of black swans which inhabited the area. The original name was actually Swartte Swaane Drift (Black Swan River).
Francis-Antoine Boniface Heirisson was the first person to draw a detailed map of the river in 1801 and Heirisson Island - where the causeway crosses) was named after him.
When James Stirling gave the river the English name 'Swan River', he only applied it to that portion of the river upstream of Heirisson Island. The section from the island downstream to Fremantle was referred to as Melville Water - a name that is still used today - although now the name Sawn River encompasses both sections. It is more correct to refer to the down stream area as the Swan Estuary.
At the time the river near where Perth sits today was described as a 'little bit brackish' (salty). Today it is as salty as the ocean and this is due to the removal of the rock bar at Fremantle, the damming of the Helena River and the Hotham River turning salty due to land clearing in the wheat belt.
Each winter an influx of freshwater from rain run-off flushes out some of the salt water. This means the creatures that live in the river must develop different responses to survive the rapid change in environment. Crabs, prawns and other salt-water species, simply swim out to sea but shellfish that cannot move must find ways to cope with the fresh water or perish.
Migratory birds from the northern hemisphere visit the Swan Estuary each year and the marine sanctuaries of Alfred Cove, Pelican Point and Milyu Beach become an important refuge in the highly urbanised area.
The river was once a vital commercial link between
Fremantle, Perth and Guildford. It could be as
expensive to ship goods from Fremantle to Guildford as it was to get the same
goods all the way from England to Australia.
32 hectares of the river were reclaimed to provide room for the Narrows Bridge interchange on the north bank. There has been a good deal of re-shaping and dredging of the river both to stop flooding and to provide land for development.
The river was once a major obstacle to travel but today there are 18 bridges spanning its waters. Starting at Fremantle and heading upstream these include:
Fremantle Railway Bridge
Fremantle Traffic Bridge
Garratt Road Bridge
Guildford Road Bridge
Guildford Railway Bridge
Upper Swan Bridge
Why does this list only show 14 bridges when we just said there were 18? because the Narrows is actually 3 separate bridges, the Causeway is 2 and Garratt Road is 2.
Over the years the river has been subject to flooding with the worst on record taking place in 1892. The most recent flood was in the late 1970s but with falling yearly rainfall averages, the threat of further floods is diminishing.
The defunct oysters did leave behind something of value, their shells. With a high lime content they were used to make cement by the Swan Cement Company and over 3 million tons of shell were dredged from the river between 1927-1956.
North - South rivalry.
People seem to have a natural tendency to divide each other into the groups 'them' and 'us'. This tendency is frequently highlighted between states and cities (especially between Sydney and Melbourne) but there is also a historic rivalry between those living north of the Swan River and those living to the south. It is perhaps less pronounced today than it used to be but at one time some businesses operated with separate phone numbers for north and south customers.
Swan River Trust
This organisation was established to oversee the use, health and condition of both the Swan and Canning Rivers. It meets bi-monthly, providing advice to the Minister for the Environment, the Western Australian Planning Commission and local governments on the future development of the river and its surrounds.
