The NSW State Water Corporation says there is no fear of flooding from Blowering Dam which is 85 per cent, not 90 per cent full.
ABC News reported incorrectly today that Blowering Dam is 90 per cent full, citing concerns from Tumut River Landowners' Association spokesman Peter Luders.
Mr Luders says regardless, the policy is to fill the dams as much as possible and after three floods in recent years, there is deep anxiety about another flood along the Tumut River.
The NSW Office of Water says all dams have a variable airspace policy, but an extra 100 gigalitres is kept in Blowering under a deal with Snowy Hydro.
State Water spokesman Tony Webber says there is actually a 15 per cent buffer in the dam at present, when Mr Luders only wants 12 per cent.
"I would hope that would be reassuring," said Mr Webber.
"That translates to 235 gigalitres of what we call airspace, or room that's left within the dam for inflows. When you consider that we haven't exceeded 10 or 11 gigalitres of inflows since late July, I would think we can see that that's still a lot of space in the dam to absorb any significant rain event in the area," he said.
