The Brisbane River rises in the southeast of the Australian state of Queensland and flows through the capital Brisbane , before moving to the Moreton Bay opens .

geography

River course

The river has its source on the slopes of Mount Stanley , about 45 kilometers east of the town of Kingaroy, and flows southeast. To the north of Harlin it passes under the D'Aguilar Highway and about 20 kilometers further forms Lake Wivenhoe , which was created by the Wivenhoe Dam ( ⊙ ) . The reservoir is the main source of water in Brisbane. At its southeast end, the Brisbane River leaves the reservoir and continues its way southeast to Ipswich . There it turns its course to the northeast, flows through the city of Brisbane in many meanders and flows next to the city's airport in Moreton Bay, a bay in the South Pacific .

There are currently twelve main bridges, including the Story Bridge and the Gateway Bridge , across the Brisbane River.

history

Discovery and naming

In 1823 the explorer John Oxley named the river after Sir Thomas Brisbane , the then governor of New South Wales .

Floods

Floods occur regularly on the banks of the Brisbane River. However, since the construction of the Wivenhoe Dam on the upper reaches of the river, these have not occurred as frequently and to a lesser extent.

On January 14, 1841, the highest water level so far was measured. In February 1893, several people lost their lives in a series of floods. The largest such disaster of the 20th century struck Brisbane on January 27, 1974.

In January 2011, heavy rainfall in the catchment area caused flooding along the course of the river.

Environmental issues

From an environmental point of view, the river has been in a bad state for many years. The cause of the environmental pollution lies mainly in the sewage, which has a high amount of nutrients, hydrocarbons , pesticides and bacteria . These pollutants accumulate in the river water and are deposited in the form of sediments. The dark color of the river is also striking. It is not recommended to swim in it.

In the past, the river bed was repeatedly dredged to make the river navigable for ships. The result was that the turbidity of the water increased, erosion set in and changes in the flood hydraulics occurred. After the expansion, a loamy sediment formed in the Brisbane River, which was no longer washed away. In September 1997 the government stopped dredging the river to prevent future environmental damage.
