The Emmaville pool has been closed "until further notice" with the Glen Innes Severn Council concerned about the impact of bushfire-fighting helicopters.
In a press release the council said they had closed the pool for two days during this week's fire emergency to give its staff the choice to leave the town, which was expected to be threatened.
But the closure has become permanent.
"Due to the emergency services helicopters using the oval Council is concerned about cross contamination into the pool from the grass and dust this generates," the release said.
"This causes the need for continual backwash and the water resources at Emmaville are not available to achieve this."

When the pool is reopened, council will publish a notice on its Facebook page and website.
Council has vowed to keep existing water in the pool treated and will endeavour to re-open it again as soon as possible.
Earlier this week the council was moved to quash a rumour that the Deepwater standpipe was being used to water roadworks.
"Council has been made aware of concerns raised by members of the Deepwater community regarding the carting of potable water from the Deepwater water standpipe for use in Roads and Maritime Services road works projects," that release read.
"Although a number of trucks regularly use the Deepwater water standpipe, the majority of this water is going to help local rural customers."
The Glen Innes Severn council did sell water for use at the Bolivia Hill roadworks on the New England highway. Initially the water came from Glen Innes reserves but later council sold water from the Deepwater weir. Water sale ended in September.
Some 192.48 kilolitres of water was provided from Deepwater, around one day's use in Glen Innes and Deepwater, according to council.
The project is now carting water from Wallangarra in Queensland.
"Council is in regular contact with local water carting contractors and to our knowledge no water is being taken from the Deepwater standpipe for use on road works projects, state or local," the release said.
