Council general manager Robert Campbell said the shire was "reasonably fortunate" to come out of the floods relatively unscathed, with no forced evacuations taking place.

About two or three voluntary evacuations were carried out, with a lot of properties in the Bloomfield St part of town significantly affected.

A major point of access, the Oxley Highway at Carroll, is open, as is the Kamilaroi Highway to Boggabri.

However, Mr Campbell said Kelvin Rd at Cohens Bridge still had "quite a bit of water over it". Releases from Lake Keepit will have some effect on the level of the Namoi River in town.

"We're pretty right. Compared to the unfortunate situation at Moree and the up-and-coming worsening situation at St George (in Queensland), we've come out of this reasonably well," he said.

"It could've been a lot worse.

"Everything's functioning. All of our services are up and running and the water's certainly still dropping.

"But we will have several hundred thousand dollars' of increases in our road damage. That relates to the pre-existing damage that we had before (from the November 2011 floods)."

He predicted the shire would face a $400,000 bill for road repairs, but it could be more.

"We don't know until we've done the details of the roads. Until we know what the true damage is ... it may be more than that. We've already got $1.2 million worth of damage from late last year," Mr Campbell said.

He said last week's floods came at a bad time, as council was taking steps to get damage from November repaired.

"One of the problems we have, of course, is that we can't get into a lot of the major, substantial works ... until we have the final assessment approved from the RTA. We can't do much by way of substantial repairs until we get our final sign-off," Mr Campbell said.

"We won't get funding for everything, obviously. It will cost our community for the works we can't get funding for, so we're hoping for as much as possible to cover that damage."
