Location and features

Catchment of the Mulgrave River southeast of Gordonvale

Sourced by runoff from the

Volcanic activity that resulted in the rise of Green Hill in the Mulgrave Valley blocked the river from entering the sea near present-day Cairns.[7] However, further research has shown river sediments above the basalt flows and it is now believed that other factors such as alluvial sediments may have altered the river's course and that perhaps it has alternated between the two mouths over time.[8]

The river is crossed by the Bruce Highway south of Gordonvale via the Desmond Trannore Bridge.

History

Gold was discovered in the river in the 1870s, bringing considerable change to the Goldsborough Valley. Gravel is now extracted from the riverbed.[6]

Together with the Russell River, the Mulgrave River has a well-recorded flood history with documented evidence of flooding beginning in the late 19th century.[9][10]

Fauna

Freshwater stonefish and crocodiles are found in the river, so caution is advised if swimming in the river.[11] The pest fish tilapia have been discovered in the river and have been the target of eradication efforts.[12]

Language

Yidinji (also known as Yidinj, Yidiny, and Idindji) is an Australian Aboriginal language. Its traditional language region is within the local government areas of Cairns Region and Tablelands Region, in such localities as Cairns, Gordonvale, and the Mulgrave River, and the southern part of the Atherton Tableland including Atherton and Kairi.[13]
