Course

The watershed of the Maroochy River encompasses 630 square kilometres (240 sq mi) of undulating hills which have been cleared for agriculture and urban uses.[2] There are three dams in the catchment area including Wappa Dam, Cooloolabin Dam and Poona Dam which total to 27,997 megalitres (988.7×10^6 cu ft) of capacity.[1]

There are two main arms: North and South Maroochy Rivers.[3] Tributaries of the river include Petrie Creek and its major tributary Paynter Creek, Eudlo Creek, Coolum Creek, Doonan Creek and Yandina Creek.[3]

There is one Canal system open to the river Maroochy Waters and a second Canal system with restricted access to river namely Twin Waters. There are also numerous lake systems which drain to the river and its creeks such as Sunshine Cove.

There are a number of named Islands in the river including Pincushion Island, Goat Island, Channel Island, Chambers Island & Bungee's Island.

Floods

Significant floods on the Maroochy River have occurred in 1893, 1951, 1974 and 1992.[4] In 1994 the Maroochy River flood warning system was set up to provide river height predictions for the Maroochy Shire Council.[4]

History

In the early days of settlement, the only way to travel from Yandina to Maroochydore was by boat along the Maroochy River.[5]

The growth of urban settlements in 1930 had improved the Maroochy River due to its transport developments.[5]

The mouth of the river was affected by the 2009 southeast Queensland oil spill, reaching about 2 kilometres (1.2 mi) upstream to the Maroochy Bridge.[6]
