About the LFRIP

Background

In December 2004, the Queensland Government, in partnership with local government, committed to developing the Central Queensland Regional Water Supply Strategy as part of the long-term water supply strategy for the region. The strategy identified that further infrastructure on the Lower Fitzroy River is required in order to provide the appropriate reliability of supply to meet the needs of urban populations, industry and agriculture. The Lower Fitzroy River Infrastructure Project (LFRIP) was identified as appropriate infrastructure to satisfy short, medium and long-term supply requirements.

The Water Plan (Fitzroy Basin) 2011 reserves unallocated water as strategic reserves, strategic water infrastructure reserves and general reserves. Unallocated water held as a strategic water infrastructure reserve may be granted for nominated water infrastructure on the Fitzroy River. A nominal volume of 76,000 ML may be granted as a supplemented water allocation from the strategic water infrastructure reserve for the LFRIP.

Key features

The key features of the LFRIP are:

  • Construction of a new weir at Rookwood, across two stages
  • Raising the existing Eden Bann Weir, in two stages
  • New and upgraded fish passage and turtle passage at Eden Bann Weir and Rookwood Weir
  • Construction of new crossings on the Fitzroy River at Glenroy, Riverslea and Hanrahan roads and on the Mackenzie River at Duaringa-Apis Creek Road (Foleyvale)
  • Upgrades to access roads and local intersections.

Eden Bann Weir

Eden Bann Weir is located approximately 62 km north west of Rockhampton on the Fitzroy River.

The existing Eden Bann Weir (Stage 1) was constructed in 1994 to supply water to Stanwell Power Station. It is a conventional concrete weir with a full supply level (FSL) of 14.5 m AHD. Eden Bann Weir is owned and operated by SunWater.

The LFRIP proposes to raise Eden Bann Weir as follows:

  • Stage 2 – Raise the existing Eden Bann Weir to FSL 18.2 m AHD
  • Stage 3 – Addition of 2 m high flap gates to achieve FSL 20.2 m AHD

Impoundment associated with the raised Eden Bann Weir extends along the Fitzroy River.

Rookwood Weir

The proposed Rookwood Weir site is located approximately 66 km south west of Rockhampton on the Fitzroy River.

Proposed development at Rookwood includes:

  • Stage 1 – Construct new weir to FSL 45.5 m AHD
  • Stage 2 – Addition of 3.5 m high flap gates to FSL 49.0 m AHD

Impoundment associated with the Rookwood Weir extends along the Fitzroy, Mackenzie and Dawson rivers.

Weirs and dams explained

What is a weir and how is it different to a dam?

Barrage Weir Dam

A barrage is an in-river structure similar to a weir but is located within the tidal zone of a river, resulting in a separation of fresh and marine water.

A weir is an in-river structure designed such that the highest level of the weir is at, or less than, the high bank of the river. A weir is designed to be overtopped by flows which exceed the rivers capacity. Weirs are not designed for flood mitigation.

A dam is an in-valley structure and utilises both the river and surrounding valley. The highest level of a dam will intersect the adjacent hills of the valley and as a result generally impounds a much greater area of land. A dam may be designed to mitigate floods and the spillway is designed to pass flood flows.

Development approach

Future demand for water resources is predicted due to the continued growth of industrial and urban expansion and agricultural development in the Gladstone, Rockhampton and Capricorn Coast areas. In addition to direct increases in demand for high priority water there is also a potential requirement to improve the level of reliability of the existing water supplies locally and regionally.

The LFRIP is expected to be staged, with sequencing and timing dependant on a number of demand triggers including existing and new urban, industrial and agricultural consumers, drought conditions and security of supply requirements. The LFRIP has been developed to be implemented by way of a flexible strategy to allow the rapid delivery of water to meet anticipated future demands, when triggered.

A staged approach to development enables Proponents to respond to potentially smaller demands in the short-term and progressively respond to increasing and/or larger demand requirements over time through intermediate infrastructure builds until full development is reached.

Demand triggers

Key potential water demand triggers include water supply to:

  • Gladstone, via the proposed Gladstone-Fitzroy Pipeline (30,000 ML/a) to satisfy demand from existing and/or new consumers and provide a contingency supply source for the Gladstone Area Water Board
  • Rockhampton and Livingstone Shire Councils to support improved reliability initiatives and increased urban water supplies
  • Industry and mining to support economic growth in Rockhampton’s Gracemere-Stanwell Industrial Corridor and industrial demand in the Gladstone region
  • Agricultural expansion and/or development projects, for example Regional Development Australia’s Growing Central Queensland initiative; the lower Fitzroy Agricultural Corridor; and linkages to development in Northern Australia to improve agricultural competitiveness regionally.
