Wyaralong Dam

Boonah, Queensland

Wyaralong Dam is the newest dam in South East Queensland, completed in 2011. The dam holds 102,883 mega litres of water at full capacity. The lake and surrounding areas also provide recreation facilities and have become a major tourist drawcard for the Scenic Rim region.

The Wyaralong Dam is located in the Logan River Catchment outside of Beaudesert.  The dam was constructed to help meet the growing demand for water from urban and industrial development and provide additional supply for the South East Queensland water grid.  The dam wall is 500 metres long and 48 metres high.  The dam wall was constructed as a roller compacted concrete dam during a continuous 24hr cycle.  The scope of works involved a 6km single carriageway road, accessing from the main road to the dam wall. Earthworks to prepare the foundation of the wall, quarry design and drill and blast.  Drilling, grouting and anchoring works at the left and right abutments.  Setout for the dam face and spillway, monitoring of the concrete lifts, intake tower and design of the gallery spaning the length of the wall.
