Dam dumps water

JUST weeks after Wyaralong Dam reached capacity, water is being released to allow workers to finish the project.

Heavy rainfall in the dam catchment area saw it exceed its 103,000 megalitre capacity less than a month after it was plugged.

On January 11, water started flowing over the dam spillway and continued until February 2, releasing almost 60,000 megalitres.

Queensland Water Infrastructure (QWI) chief executive Frankie Carroll said several elements of the dam project had to be completed during the coming months.

Mr Carroll said it was necessary for controlled releases of the dam water to ensure employees could finish the project properly.

“Since February 3, controlled releases have been occurring through the valves to lower the water level of the dam by approximately 20,000 megalitres to safely finish the project,” Mr Carroll said.

“The water is being released at a rate of approximately 1000 megalitres a day over 20 to 30 days, depending on the weather.”

Mr Carroll said this amount of water – “less than one per cent of the dam’s capacity a day” – would have minimal impact on Teviot Brook, which flows into the Logan River.

“Over the next couple of months, finishing work on the dam, such as electrical and mechanical installations and site rehabilitation, including completing the planting of environmental corridors and the Mt Joyce Escape Recreation Park outdoor facilities, needs to be completed,” he said

“Up to 40 kilometres of multi-use recreation trails and about 25 kilometres of competition standard mountain bike tracks are taking shape around the dam.”

Other recreational facilities, including development of two main trailheads, barbecue and picnic facilities, camp grounds and toilets, are well advanced at both ends of the dam.

Mr Carroll said the controlled dam releases would ensure the project was on track for completion by the middle of the year.
