The Logan River (Yugambeh: Dugulumba) is a perennial river located in the Secenic Rim, Logan and Gold Coast local government areas of the South East region of Queensland, Australia. The 184-kilometre (114 mi)-long river is one of the dominant waterways in South East Queensland that drains the southern ranges of the Scenic Rim and empties into Moreton Bay after navigating the City of Logan, a major suburban centre located south of Brisbane. The catchment is dominated by urban and agricultural land use. Near the river mouth are mangrove forests and a number of aquaculture farms.

The river rises below Mount Ernest on the southern slopes of the Scenic Rim, part of the Great Dividing Range and forms in the Mount Barney National Park, near the Queensland – New South Wales border, below Mount Lindesay. The river flows generally north by northeast, joined by eleven minor tributaries, before heading east and eventually emptying into Moreton Bay. Its principal tributaries are the Albert River which joins it just east of Beenleigh; Teviot Brook which begins at Mount Superbus and joins the Logan River at Cedar Pocket; and Burnett Creek which is subverted by the Maroon Dam west of Rathdowney. The river descends 380 metres (1,250 ft) over its 184-kilometre (114 mi) course.

In addition to the Scenic Rim, the Logan and its tributaries drain more than 3,000 square kilometres (1,200 sq mi) including the northern parts of the Border Ranges, the western slopes of the McPherson Range and the eastern slopes of the Main Range. The river's upper catchment is heavily influenced by the national parks of Tamborine, Mount Barney, Moogerah Peaks, Main Range and the Lamington Plateau, and numerous local government-owned reserves and conservation areas, that comprise part of the Shield Volcano Group of the UNESCO World Heritage Site Gondwana Rainforests of Australia.

The river is crossed by the Mount Lindesay Highway near {Rathdowney and at North Maclean via Maclean's Bridge. The river is also crossed by the Pacific Motorway and the Old Pacific Highway south of Loganholme. The Beenleigh railway line crosses the Logan between Loganlea and Bethania.

Water harvesting

Maroon Dam subverts Burnnett Creek, and supplies water to the Beaudesert Shire. Maroon is managed by SunWater and covers approximately 106 square kilometres (41 sq mi). The Queensland Government has considered several projects to supply water to its Southern Regional Pipeline. The Bromelton off-stream storage facility is under construction on the Logan River, outside Beaudesert, as is the Cedar Grove Weir, near Jimboomba. In 2006 the Queensland Government decided against the construction of a Logan River dam at Tilley's Bridge in Rathdowney due to mounting public pressure and high road diversion costs. Instead, the Wyaralong Dam was proposed on Teviot Brook near Boonah which will inundate fifteen properties instead of the one hundred properties for the Tilley's Bridge site. The Tilley's Bridge dam, if it had been approved, would have inundated the area of land between Tilley's Bridge, just to the south of Rathdowney, and Bigriggan Camping Reserve, some 8 kilometres (5.0 mi) west, covering a significant section of the Boonah-Rathdowney Road.

History

The Yugambeh clan of the Jagera people are thought to have once roamed throughout the catchment. Traditional owners in the catchment made use of the abundant natural resources, various plants and animals were used as staple foods as the seasons changed and as new food sources became available. hey called the river Dugulumba in their traditional Yugambeh dialect of the Bandjalang language.

The river was discovered by Europeans in August 1826 by Captain Patrick Logan. Logan initially named the river the Darling River, but to avoid confusion, Governor Ralph Darling ordered the name be changed to honour its discoverer.

Boat traffic was thriving along the river by the 1860s mostly because it was the best transport route in the area. Steam ships, cutters and hand-loaded punts were the most common vessels.

For navigation purposes the river was surveyed in 1871 from its mouth upstream to McLean. Wharfs were initially built at McLean, Beenleigh, Waterford and Logan Village with more built due to public demand. Unofficial ferry crossing were conducted as early as 1862. Long-term services were established at Alberton, Loganholme and Waterford. The rail bridge at Loganlea was operating in 1885 only to be demolished two later during floods. A new bridge opened in 1888 and lasted until 1972 when another bridge was built.

In 1905, a crocodile was found dead on the banks of the river. The find was preceded by reports of sightings for several years which were met with skepticism because southern Queensland is well south of their natural distribution.

A toll bridge on the river north of Beenleigh was collecting money by the late 1930s as weekend traffic between Brisbane and the Gold Coast increased.

The flooding in the lower reaches of the river were the worst for the 20th century during the 1974 Brisbane flood.

Water quality and conservation

The quality of the water in the Logan River is very turbid. The annual Healthy Waterways Report Card for the waterways and catchments of South East Queensland rated the condition of the Logan River as very poor. Much of the environmental degradation has been caused by land clearing, the Bromelton Industrial Estate, nutrient run-off and the pumping of wastewater directly from several wastewater treatment plants in and around the Logan River. In 2009, the Healthy Waterways Ecosystem Health Monitoring Program rated the River's freshwater area at a "D"; its Estuarine area was given an "F".

Community projects in the Logan catchment area aim to improve the quality of the ecosystem. Competitions such as Carp-busters are aimed at reducing the number of carp and hence allowing native species of fish a better chance of survival.
