Port River

Port River

Port River (coord|34|45|S|138|30|E|region:AU-SA) is a river that runs through Port Adelaide, a part of the capital of South Australia, Adelaide. The River separates the LeFevre Peninsula, Adelaide’s suburbs and Torrens Island, and is the sea entrance to the port facilities of Adelaide. The Port River does not flow from any significant source but is largely a tidal inlet from Gulf Saint Vincent. It drains the constructed saltwater lakes of the West Lakes district in the western suburbs of Adelaide and connects to the Barker Inlet via the "North Arm" and "Angas Inlet" which surround "Garden Island".

The banks of the river are largely industrialised and have some of Adelaide’s wharves, bulk cargo and container handling facilities although there are some remnant mangroves. One of its main attractions other than transport is the Port River dolphins, who are the only wild dolphins in the world that live within a city.

Apart from ship transport using the river’s main channel, a fishing fleet operates out of the "north arm" which also has a speed boat club and boating marina. The Australian Submarine Corporation has its maintenance facility and dock at Osborne, there is a Quarantine Station on Torrens Island and Torrens Island, Pelican Point power station abuts the river. The Port Adelaide Rowing Club has rowed on the river for one hundred and thirty years [ [http://www.messengerwest.com.au/article/2007/07/18/1623_west_news.html Messenger Community Newspapers Local News Adelaide South Australia ] ] , and the river was formerly a frequent venue for the Intervarsity eights race.

Environment

There are some mangroves (avicennia marina var resinifera) remaining from the pre-settlement forests along Torrens Island, the north arm of the river and north of the Submarine Corporation near "mutton cove". Spring tides are over 2½ metres and at low tide mudflats are exposed near the outlet of the river, forming a breeding ground for blue swimmer crabs and other species. A 118 km² Dolphin sanctuary [cite web|url=http://www.environment.sa.gov.au/coasts/ads/location.html|title = Adelaide Dolphin Sanctuary, Location and Maps|publisher=South Australian Department of Environment and Heritage |accessdate = 2006-12-26|date = 2006] was enacted by the 2005 "Adelaide Dolphin Sanctuary Act" [cite web| url=http://www.austlii.edu.au/au/legis/sa/consol_act/adsa2005238/ |title= ADELAIDE DOLPHIN SANCTUARY ACT 2005|accessdate=2006-12-26] and covers all of the Barker Inlet and Port River. Bottlenose dolphins are often seen in the river, examine and follow small boats and have become a well known tourist attraction with dolphin cruises departing from "Queens Wharf".

ettlement history

Prior to the 1836 settlement of South Australia, the river was a shallow and narrow tidal creek winding between mangrove swamps. The river was officially discovered in 1834 by Captain John Jones after an 1831 sighting by Captain Collet Barker. cite web|url= http://users.olis.net.au/penta/history.htm |title=HISTORY OF PORT ADELAIDE |publisher=Port Adelaide Historical Society |accessdate=2007-01-03] The initial landing place in Adelaide was some way north of the current port and had such poor conditions that for many years it was known as "Port Misery". In 1837 a harbour was declared when harbourmaster Captain Thomas Lipson took up residence on the shore of the then named port creek with the first migrants landing in the same year and Mclaren wharf built in 1839.cite web|url= http://www.southaustralianhistory.com.au/portadelaide.htm |title= Port Adelaide |publisher =Flinders Ranges Research |accessdate =2006-01-03] The current port location was opened in 1840 but, due to the shallow depth of the river, a new harbor was authorised for construction at Outer Harbour in 1902 and completed in 1908. This new harbour allowed the larger steamships that were then arriving at Adelaide to dock, with smaller steam vessels and sailboats able to use the old port facilities.

The river was first bridged in 1859 opening the LeFevre Peninsula to development and now is crossed by 3 road bridges including the Birkenhead bridge, the first bascule moving bridge in Australia.

hips graveyard

The North Arm contains a significant ships graveyard with 25 identified wrecks and was also used to house explosives stores from the 1880s.
