Known by locals as ‘the Yarra,’ there’s much more to the Yarra River than meets the eye.
Despite being one of the city’s most recognisable natural landmarks, even locals know little about the Yarra River. Here are six interesting facts you need to know:
The river that runs upside-down
The Yarra River is often referred to as the “upside-down river” because of its brown colour. The strong brown, muddy colour of the river is caused by clay soils. The clay soil in the region breaks up into tiny particles and dissipates throughout the whole of the river. The Yarra had clear water before European settlement but during the industrial revolution in the 19th century, high levels of land clearing and development caused these microscopic clay particles to enter the water, making it the colour it is today.
Victorians are concerned about the health of the Yarra
Due to stormwater runoff, up to 350,000 cigarette butts enter the Yarra catchment every day, which is a small representation of the rubbish that makes its way into the river and locals are worried. In fact, new research commissioned by Ocean Protect, shows Victorian residents are extremely concerned about marine and waterway health in relation to population growth – over half rated it as their number one concern from a total list of 12 common concerns including increased traffic, housing density, competition for jobs and possible reduced water supply. The study also found that 70 per cent of Victorians don’t know that stormwater is the leading source of pollution in city and suburban waterways include the Yarra.
The current name of the river was translated incorrectly
The actual name of the Yarra River is Yarro-yarro, which is a Wurundjeri term in the Boonwurrung language meaning “ever-flowing.” This is a very accurate description as the river is a perennial waterway, meaning it has a continuous flow all year round due to years of normal rainfall.
Main food source for Indigenous Australians pre-European history
The Yarra River played a pivotal role for the Wurundjeri people, serving as their epicentre for food, meeting and camping. The Wurundjeri people caught eels in the lagoons and swamps of the river and also fished using funnel shaped fish pots.
A history of flooding
The first recorded flood in the Yarra River was in 1839. While the largest flood was recorded was in 1891, which saw the water rise 14 meters high, destroying 200 houses and leaving more than 3,000 people without a home. The last time the Yarra experienced a major flood was in 1934, when the region endured 48 hours of rain, which destroyed 400 buildings and left 6,000 people homeless. Following this, the river was widened to protect Melbourne residents from future flooding.
Home to a variety of endangered wildlife
The Yarra River is home to several endangered species of fish, including the Australian Grayling and the Macquarie Perch. The Macquarie Perch’s population is dependent on the Yarra River, as there has been a major decline in the Murray-Darling Macquarie Perch population. The Yarra River is also home to other creatures; there are 18 species of frogs, 57 species of wetland birds and 113 species of streamside birds as well as waterbugs and platypus.
