The weir is located 14 kilometres (8.7 mi) northwest of Beaudesert, and 5 kilometres (3.1 mi) southwest of Jimboomba and is connected to the Wyaralong Dam on Teviot Brook and the Bromelton Offstream Storage facility. The project was completed in December 2007 at a cost of A$18.5 million and provides up to 11 megalitres (390×10^3 cu ft) of water per day. Initially managed by Queensland Water Infrastructure, a body set up to administer major water infrastructure projects, the weir is now manager by SEQ Water.
In conjunction with the South Maclean Weir and water treatment plants, the Cedar Grove Weir acts as a pumping pool for captured releases from Wyaralong Dam located upstream; and provides immediate supplies to the Beaudesert region. The weir also connects to the regional South East Queensland Water Grid. The weir overflowed for the first time on the 4 January 2008.
