Rookwood Weir

Rookwood Weir is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Rookwood Weir rather than just read about it. In short: The Rookwood Weir (Darumbal: Managibei Gamu, meaning keeping – saving [water]) is a concrete weir across the Fitzroy River, located near Gogango, approximately 66 kilometres (41 mi) south-west of Rockhampton, in Central Queensland, Australia. The weir was constructed to assist with the supply of water for agriculture, potable water for the Livingstone Shire Council, and industrial needs.

Key takeaways

Rookwood Weir belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Rookwood Weir to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Rookwood Weir from memory before moving on to harder problems.

Reference excerpt

The Rookwood Weir (Darumbal: Managibei Gamu, meaning keeping – saving [water]) is a concrete weir across the Fitzroy River, located near Gogango, approximately 66 kilometres (41 mi) south-west of Rockhampton, in Central Queensland, Australia. The weir was constructed to assist with the supply of water for agriculture, potable water for the Livingstone Shire Council, and industrial needs.

Overview Built between 2020 and 2023, and officially opened on 22 November 2023 by the Queensland Treasurer Cameron Dick and the Federal Minister for the Environment and Water Tanya Plibersek, it was reported that the weir was the largest built in Australia since World War II. Funding for the weir was provided jointly by the Australian and Queensland governments at a cost of A$568.9 million. The weir is situated downriver from the confluence of the Dawson and Mackenzie rivers, in the upper reaches of the Fitzroy, and upriver from the Eden Bann Weir and the Fitzroy River Barrage. Managed by SunWater, the weir is 16.2 metres (53 ft) high and 350 metres (1,150 ft) long. The resultant reservoir has a full supply volume (FSV) of 74,325 megalitres (60,256 acre⋅ft), with a yield at FSL of 86,000 megalitres (70,000 acre⋅ft) that covers 1,930 hectares (4,800 acres), and with a shoreline that is 60 kilometres (37 mi) in circumference. The spillway is 202 metres (663 ft) long. During 2023, agriculture investment was announced with a macadamia farm and a cattle feedlot development underway, supported by water supplied from the weir. The weir includes a specially-designed passage to allow local turtles, including the Fitzroy River Turtle and the White-throated Snapping Turtle, to travel up and downstream to breed, seek shelter, and find food; as well as an innovative fish lock.

Worked examples

Example 1 — a first encounter with Rookwood Weir

Start with the simplest possible case. Write down what Rookwood Weir claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Rookwood Weir before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Rookwood Weir ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Rookwood Weir

In research: Rookwood Weir appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Rookwood Weir in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Rookwood Weir is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2023 establishments in Australia, Buildings and structures in Central Queensland, Dams completed in 2023, so understanding it makes those chapters shorter.
In everyday life: Look for Rookwood Weir outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
