Dam release should not close road
SEQWATER has stopped short of providing a guarantee that the pending release of water from Wivenhoe Dam will not flood Colleges Crossing.
Dam operators are planning a seven-day release pattern beginning late tomorrow afternoon, which will result in 57,000 megalitres of water spilling into the Brisbane River at a rate of about 120 cubic metres per second.
It follows a Queensland Government decision to drain the dam to 75% as a precaution for this year's wet season, which the Bureau of Meteorology said could deliver high rainfall.
In a statement released this week, south-east Queensland's water grid managers said the releases would affect some local bridges close to the dam.
However, the water was not expected to reach such a level in the Brisbane River that it would force the closure of Colleges Crossing, or interfere with Somerset Regional Council's permanent restoration works at Savages Crossing.
Twin Bridges will be closed for the duration of the release and while Savages Crossing will be closed initially as a precaution, it could be open again by Saturday morning depending on flows.
"The release rate is not expected to impact Colleges Crossing or provide any noticeable change to water levels in the Brisbane River below Moggill," SEQ Water said in a statement.
Brisbane City Council's Pullenvale Ward representative, Margaret de Wit, said residents on both sides of the river deserved a promise after all they'd been through last year.
"In 20-plus years of living in the western suburbs I have never seen water released from Wivenhoe without it causing Colleges to close," she said.
"I would like an assurance from the CEO of SEQWater that Colleges Crossing will definitely not go under as a result of this release from Wivenhoe Dam."
Burtons Bridge, Kholo Bridge, Mt Crosby Weir Bridge, Fernvale Bridge and all other bridges and crossings below Moggill were also not expected to be affected by the release.
The viewing platform at Wivenhoe remains closed but people can watch the releases on an operational safety camera at Watergrid.
