Authorities say there is still a danger a leaking dam at Talgai could fail, as engineers work to stabilise its wall and construct a water bypass channel.
Authorities are still working to stabilise a leaking, privately owned 430-megalitre irrigation dam on Queensland's Southern Downs amid fears its wall could fail.Some roads remain closed, but most residents have been able to return homeAn emergency was declared in the area around the dam near Talgai, north-west of Warwick, on Friday night after the property owner found water gushing from a 3.5-metre by 1.5-metre hole in the wall.
Residents were evacuated on Friday, but most were allowed to return home on Sunday night when the emergency alert was lifted."There is instability in the dam wall, which is why the concern is still there the wall will give way," she said. "A bypass channel will be constructed around the southern edge of the dam wall to take the water away from the wall in a controlled manner.
"That will be released down that valley and will contribute to the need for road closures because there will be flooding.
