Dalby residents are being asked to conserve water because of flooding in the Condamine River.
The Western Downs council says the town's treatment plant is safe but some outlying bores are being affected by flooding.
Mayor Ray Brown says there are enough supplies for the town but level five restrictions are being enforced as a precaution.
"By closing off and decommissioning the bores themselves to make sure the electricity is cut off we're in a position to recommission them very quickly and that's the key point, being prepared and having a contingency in place," he said.
The Condamine River at Condamine is at 10 metres and the bridge to the town remains open this morning.
Authorities say the river will reach at least 12 metres, isolating the town for a week.
