It begins in the Mount Barney National Park, near the New South Wales border between Mount Lindesay and Mount Ernest, before heading north, east, and eventually flowing 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 Logan was discovered 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.cite book |title=Stories of the Southside |last=Roberts |first=Beryl |authorlink= |coauthors= |year=1991 |publisher=Aussie Books |location=Archerfield, Queensland |isbn=094733601X |pages=45 ]

Water harvesting

Maroon Dam subverts Burnnett Creek, and supplies water to the Beaudesert Shire. Maroon is managed by SunWater and covers approximatley 106km².Several projects are underway, to supply water to the Queensland Government's "Southern Regional Pipeline". The Bromelton off-stream storage facility is currently under construction on the Logan River, outside Beaudesert, as is the Cedar Grove Weir, near Jimboomba.

On July 4, 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 15 properties instead of the 100 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 eight kilometres west, covering a significant section of the Boonah-Rathdowney Road.

Water quality and conservation

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. [ [http://www.ehmp.org/filelibrary/1_reportcard2007.pdf EcosystemHealth Monitoring Program, “ReportCard ‘07”] , accessed 25 November 2007.] Much of the environmental degradation has been caused by land clearing, the Bromelton industrial estate, [ [http://www.healthywaterways.org/logan_albert.html EcosystemHealth Monitoring Program, “About SEQ Waterways: Logan – Albert Catchments"] , accessed on 30 January 2007.] nutrient run-off and the pumping of wastewater directly from several wastewater treatment plants in and around the Logan River. [ [http://www.epa.qld.gov.au/publications/p00351aa.pdf/LoganNerang_water_quality_study.pdf Queensland Government, Environmental Protection Agency, “Queensland Waterways No. 3, March 2001 – Logan-Nerang Water Quality Study"] , accessed on 25 November 2007.]

Community projects exist in the Logan catchment area to clean up enhance the quality of the ecosystem. Competitions such as "Carp-busters" are aimed at reducing the number of Carp, and therefore allow native species of fish a better chance of survival.
