context_page_description: The Brisbane River is the longest river in South-East Queensland, Australia, and flows through the city of Brisbane, before emptying into Moreton Bay on the Coral Sea. John Oxley, the first European to explore the river, named it after the Governor of New South Wales, Sir Thomas Brisbane in 1823. The penal colony of Moreton Bay later adopted the same name, eventually becoming the present city of Brisbane. The river is a tidal estuary and the water is brackish from its mouth through the majority of the Brisbane metropolitan area westward to the Mount Crosby Weir. The river is wide and navigable throughout the Brisbane metropolitan area.
  The river travels 344 km from Mount Stanley. The river is dammed by the Wivenhoe Dam, forming Lake Wivenhoe, the main water supply for Brisbane. The waterway is a habitat for the rare Queensland lungfish, Brisbane River cod, and bull sharks. The largest ship built on the river was the Robert Miller. The 66,000 tonne vessel became un-moored in the 1974 Brisbane flood. While not the highest experienced along the river since European settlement, this flood was the most damaging. Major floods also occurred in January 2011 and multiple times during 1893.
context_section_description: In 1895-1896, the Queensland lungfish was only found in the Mary and Burnett river systems. Concerned about the species survival, it was introduced into other Queensland waterways with varying success. Self-sustaining populations of lungfish were successfully established in the Brisbane River, the Enoggera Reservoir and the North Pine River.
