Our river's incredible surge

THE Bremer River peaked below its expected level of 20.5 metres at the height of the flood, hitting 19.35m.

The Bureau of Meteorology said the river peaked at 5.05pm Wednesday before falling back to 19.30m by 5.44pm and, like Wivenhoe Dam, it has continued to drop.

Seqwater Grid chief executive Barry Dennien said the dam was currently at 187 per cent and was gradually dropping with controlled releases through all five gates, of 215,000 megalitres per day.

This is down from the peak of 645,000 megalitres earlier in the week.

“The dam’s slow recession is due in part to inflows of 121,000 megalitres per day via a sluice gate from Somerset Dam,” Mr Dennien said. “Somerset is at 174 per cent.”

After the expected downstream peak in the lower Brisbane River has passed, releases will be increased to 301,000 megalitres per day.

Mr Dennien said the increase was unlikely to cause a second significant rise in the river and was necessary in order to relieve Wivenhoe Dam’s swollen flood storage compartment in order to create space for further rainfall and inflows, should they occur.

“All releases are being made in consultation with the Bureau of Meteorology and local councils and every effort is being made to limit downstream impacts where possible,” he said. “Due to a combination of Lockyer Creek, local runoff and Wivenhoe releases, Twin Bridges, Savages Crossing, Burtons Bridge, Kholo Bridge Colleges Crossing, Fernvale Bridge, and Mt Crosby Weir Bridge may be inundated until at least Sunday.”
