The Canning River is a river in the southwest of the Australian state of Western Australia .

geography

The source of the river is on the western slopes of the Darling Range , about ten kilometers north of the small town of North Bannister , east of the Albany Highway . The river flows northwest past Mount Cooke and Mount Randall , always up to ten kilometers from the highway. It crosses the northwestern part of the Monadnocks Conservation Reserve and is dammed into the Canning Reservoir shortly before reaching the urban area of Perth . From there, the river continues northwest, meandering through the southeastern suburbs of Perth in the Swan River's coastal plain , such as Cannington, Thornlie, Riverton, Shelley, Rossmoyne and Mount Pleasant . In Melville Water River, below the Canning Bridge , opens the Canning River in Swan River.

history

Europeans first saw the river in 1801 when a French expedition discovered the confluence with the Swan River. The crew named the estuary Entrée Moreau after Charles Moreau, their midshipman .

The Canning River was given its current name in 1827 by Captain James Stirling on board the HMS Success after exploring the area in March 1827. Stirling named the river after George Canning , an important British politician who was British Prime Minister at the time and whose government provided the funds for the expedition approved.

In November 1829, just five months after the Swan River Colony was founded , another expedition, led by Governor James Stirling, laid down a place for a new town named Kelmscott after a place on the Thames on the banks of the Canning River .

Convicts

Convicts built the Canning River Convict Fence so ships could move wood from Mason's Timber Mill in the Darling Range to Perth. It is still a sight today.

ecology

Many wild animals live in and around the river, such as dolphins , pelicans , swans and many other species of birds.

Algal bloom

Natural algal blooms occur regularly in the Canning River system. It is caused by the build-up of nutrients in the river. Human activities such as agriculture and the creation of gardens and parks have only exacerbated this phenomenon. The flowers are believed to be poisonous to mammals as well as fish and other aquatic life. The Swan River Trust monitors the river's nutrient levels and algae growth and issues warnings or closes sections of the river to swimmers and water sports enthusiasts. The Trust also runs purification programs to reduce the amount of nutrients reaching the river, as well as dephosphorization and oxygenation in places where algal bloom has been detected.

The appearance of carpets of algae ferns on parts of the Canning River has been welcomed by the Trust, as this fern limits the amount of sunlight available to the algae and absorbs large amounts of phosphorus and other nutrients from the water. However, it is also possible that algae fern carpets reduce the oxygen content in the water and give off a strong smell of sulfur compounds.
