Cedar Grove Weir
lake in Australia
The Cedar Grove Weir is a weir located across the Logan River in the South East region of Queensland, Australia. The main purpose of the weir is for potable water storage.
Location and features
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 managed 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 4 January 2008.

This brief starts where responsible research should: with the source description of “Cedar Grove Weir” as lake in Australia. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as lake in Australia. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Jul 1, 2026. The linked authority identifier is Q5056738. Authority coordinates are -27.846, 152.975. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2007 and 2008.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
