People are being urged to evacuate in southern Queensland amid fears a dam is in imminent danger of failing.
An emergency warning was issued after a 5.5-metre hole formed at the bottom of the 430 megalitre Bolzan Quarry Dam on Dalrymple Creek, about 30 kilometres north of Warwick, at about 5:00pm on Friday.
The dam wall has not yet collapsed, however attempts to repair the hole have failed so far.
Authorities will put up a drone this morning to assess the integrity of the dam.
An emergency alert has been issued for people in parts of Talgai, with flooding expected to occur between Talgai West Road and Dalrymple Creek Road.
Residents have been told to leave for higher ground, with dangerous downstream flooding expected to hit low-lying areas.
Southern Downs Mayor Tracey Dobie said the water was leaking at an alarming rate, with at least 250 properties expected to be affected.
“So the dam has broken at the base of the dam and the water is coming out at a considerable rate of knots right now and because the Dalrymple Creek is already in a moderate flood because we’ve had extensive rain, this water will come down that creek very, very quickly,” Cr Dobie said.
“The Queensland Fire and Emergency Services have prepared a polygon based on the anticipated spread of that water when that dam wall bursts.
“The area is already saturated from the considerable rain we’ve had in the last week and Dalrymple Creek has been breaking its banks the last couple of days.”
An evacuation centre has opened at Warwick Christian College, 70 Horsman Road, Warwick.Â
