The Namoi River peaked in the town about 7.1m on Sunday and predictions are the shire's roads will have sustained serious damage ? on top of the damage from the floods from November last year.

"We're all just sick of it at the moment. It's really steamy and horrible; it's like a sauna out there at the moment," Cr Faber said.

"We need the water to go down so we can see how bad the damage is to the roads system. We still haven't even done the assessment for the (flood) in November. It's going to be massive.

"From what I can see where the water came through in the flash part of this flood, it's just gouged the bottom out of roads. It didn't just take gravel off, it ... caused washaways.

"We're going to have a pretty massive bill. It's a pretty big task; it's going to be beyond our capability, even if we had the money."

She said the government needed to spend money on building infrastructure such as metre-high culverts on the region's highways, to enable floodwaters to flow under, rather than over, roads.

"It's time, when governments help us for flood repairs, to give us some money to repair them so they don't get washed away," Cr Faber said.

"Stop throwing good money after bad and let's take the time and fix these things properly and enable us to keep moving."

She predicts the repair bill for flood-damaged roads in the Narrabri and Moree Plains shires to total $40 million, due to combined damage from floods in November last year.

"We really need a bit of focus on our area. We don't just mean assistance with a bit of interest relief for businesses ? we really need some infrastructure. In reality we need big dollars," she said.

While Narrabri has yet to see the last of the floodwaters from the Tamworth region, she said she expected the Namoi River to stay at about the level it was yesterday before it started to slowly recede.

"Everyone's in mop-up mode," she said.

"The council will be going around trying to collect wrecked stuff from houses and things this week."
